This PhD by project is an examination of process-based architectural design. It offers an examination of one approach to undertaking process-based experimentation in architecture - based on reflection of my own practice and body of work - through which I have been able to consider a complex array of questions and issues that are associated with working in this way.

The performance of product development processes is important to the commercial success of new products. The improvement of these processes is thus a strategic imperative for many engineering companies - the aero-engine is one example of a complex product for which market pressures necessitate ever-shorter development times. This thesis argues that process modelling and simulation can support the improvement of complex product development processes. A literature review identified that design process modelling is a well-establishedresearch area encompassing a diverse range of approaches. However, most existing tools and methods are not widely applied in industry. An extended case study was therefore conducted to explore the pragmatic utility of process modelling and simulation. It is argued that iteration is a key driver of design process behaviour which cannot be fully reflected in a mechanistic model. Understanding iteration can help select an appropriate representation for a given process domain and modelling objective. A model-based approach to improve the management of iterative design processes was developed. This approach shows that design process simulation models can support practice despite their limited fidelity. The modelling and simulation framework resulting from this work was enhanced for application to a wider range of process improvement activities. A robust and extensible software platform was also developed. The framework and software tool have made significant contribution to research projects investigating process redesign, process robustness and process optimisation. These projects are discussed to validate the framework and tool and to highlight their applicability beyond the original approach. The research results were disseminated in academia and industry - 72 copies of the software were distributed following requests in the first three months of its release.

The concert industry has been expanded enormously the last couple of years. At the same time as the increasing engagement for concerts, the digital market is growing rapidly. Today during concerts, people use their smartphones to send text messages, connect on social media, take photos, record film clips, and use the flashlight function in a replacement of a lighter. This behaviour may be perceived as a distracting moment and instead moves the person’s focus from the live performance to the phone. The distracting moment can be solved by making an application that makes the interaction more enjoyable through the study of user experience. This can lead to more focus on the music and therefore, enhance the concert experience. In this project, the work behind the development of designing prototypes is described. The method used in the thesis is the process of Design Thinking. The process is divided into a five-step model: empathize, define, ideate, prototype and test. The result presents three prototypes that are based on digital competitions that interact the audience during a concert experience. At the end of the thesis, a discussion about how to secure a positive outcome of interacting the audience and the artist is presented. The conclusion was that the interactions have good potential to work in a concert environment, but the interactions need to be additionally tested to secure a positive outcome. Another conclusion was that the time before a concert has more scope to make interactions work well and to not distract the users from the live performance. / Konsertindustrin har expanderat enormt de senaste åren. Samtidigt som det ökande engagemanget för konserter, växer den digitala marknaden snabbt. Idag använder publiken sina mobiltelefoner under en konsert för att skicka textmeddelanden, ansluta på sociala medier, ta foton, spela in filmklipp och använda ficklampans funktion som en tändare. Det här beteendet kan uppfattas som ett distraherande ögonblick och i stället flytta personens fokus från konserten till telefonen. Det distraherande ögonblicket kan undvikas genom en studie av användarupplevelse som gör att en mobilapplikation gör samspelet smidigare. Det kan leda till mer fokus på musiken och genom det förbättra konsertupplevelsen. I det här projektet beskrivs arbetet bakom utvecklingen av prototyper. Metoden som används i rapporten är processen Design Thinking. Processen är uppdelad i en femstegsmodell: sympatisera, definiera, föreställa, prototyp och testa. Resultatet presenterar tre prototyper som bygger på digitala tävlingar som interagerar publiken under en konsertupplevelse. I slutet av rapporten presenteras en diskussion om hur man kan få ett positivt resultat av att interagera publiken och artisten med varandra. Slutsatsen var att interaktionerna har god potential att fungera i en konsertmiljö, men interaktionerna måste testas ytterligare för att säkerställa ett positivt resultat. En annan slutsats var att tiden före en konsert har mer spelrum för interaktionerna att fungera bra och att inte distrahera användarna från konsertupplevelsen.

In surgery, suturing is the use of needle and thread to join cut and/or damaged anatomical structures together. This repair strategy is highly versatile and is universal for all types of surgery as the goal is to restore, repair or improve function and/or appearance. The needles are almost always curved in shape, and it is handled and maneuvered by surgeons with a special tool called: needle driver. The versatility of this setup has proven its worth over time as needle drivers are one of the indispensable instruments in all types of surgery. We are entering a future where robots can be programmed to execute tasks with much higher level of precision and speed compared to humans. Medical robotics in surgery has gained ground over the past decades due to promising clinical results. A straightforward step in this direction would be to create a solution that enables the robot to grip needle driver. The purpose of this study was to develop a gripper tool that enables a collaborative robot to perform suturing with one of the most common types of needle drivers used in surgery. The Double Diamond design framework was employed. The selected content in the predefined four phases were: 1) Discover: Observation, MoSCoW Prioritization, Brainstorming, Choosing a Sample, Fast Visualisation, 2) Define: Assessment criteria, 3) Develop: Physical prototyping 4) Deliver: Final testing and Evaluation. In the first phase, Discover, clinical and technical demands were formulated. In the second phase, Define, numerous design ideas were generated and drafted on paper whereof the one with highest assessment score was chosen for physical prototyping. In phase three, Develop, the selected design idea was modelled in cardboard, clay and silicon, and 3D printed. Multiple design iterations were guided by feedback from clinical and technical experts and resulted in a final prototype design that was accepted by the experts. In phase four, Deliver, the final prototype was subjected to final testing and evaluation. Observation of five live and one video recording of surgical procedures on real patients were made. The insights gained were confirmed with the lead and co-surgeons of each procedure and were summarized in 24 clinically important observations relevant for the gripper tool design. Careful analysis of the previously designed gripper tool, live observation of the robot’s motion pattern and range, and interview with robotic engineer were summarized in ten technically important observations. The observations were then used to formulate the clinical and technical demands that the gripper tool design aims to fulfill, followed by prioritizing the demands and design features according by MoSCoW method and brainstorming on how to improve previous gripper tool design. To limit the scope of the design challenge, one of the five types of needle drivers used in pediatric heart surgery in Lund was selected in the method Choosing a Sample. To further characterize the clinical and technical demands, a test bench was set up to Define and measure force vectors applied on the needle driver when held by a surgeon during suturing. The radial forces vectors in six directions perpendicular to the tip of the needle driver ranged from 1.6 N to 3.8 N. The axial force along the length of the needle driver was 7.6 N towards the tip and 8.4 N towards the back end. The clockwise and counterclockwise torque along the length axis of the needle driver was 0.2 Nm and 0.18 Nm, respectively. The set of defined demands were sufficient to sketch numerous ideas of gripper tool designs according to the Fast Visualization method. These designs were then used in the Define phase to communicate the design ideas with surgeons, robotic and product development engineers. The most promising idea was advanced to the Develop phase where physical prototypes were produced in cardboard, clay and silicon and 3D printed. Inadequacies were found during design feedback with interviews and testing together with clinical and technical experts, and design actions were taken to arrive at the final prototype. The final prototype was brought into the Deliver phase for final testing and evaluation. The gripper tool could handle lager force loads than the human surgeon in all the stability tests. However, deflection of the needle driver occurred with the gripper tool unlike when the surgeon was subject to stability testing. One pediatric heart surgeon and one robotic engineer was asked to generate a composite score of fulfillment rate from 1–5, where 1 is bad, 3 satisfactory, and 5 excellent after final testing of the gripper tool was carried out. The final prototype of the gripper tool fulfills all clinical and technical demands at the level of 4, and 3–5, respectively. In conclusion, the design methodology used in this study was useful in the development of a gripper tool design that respects both clinical and technical demands. This suggest that the methodology may be used in similar setting of design challenges in the field between medical and technical innovation. The gripper tool fulfilled the demands, although further refinement in the choice of material, further testing and investigation of regulatory aspects are required before it can be implemented in the operating room. / Vid operation är suturering användningen av nål och tråd för att sammanfoga snittad och/eller skadade anatomiska strukturer. Denna reparationsstrategi är mycket mångsidig och universell för alla typer av kirurgi eftersom målet är att återställa reparera eller förbättra funktion och/eller anatomisk defekt. Nålarna är nästan alltid krökta i sin form och de hanteras och manövreras av kirurgerna med ett speciellt verktyg som kallas: nålförare. Mångsidigheten i denna uppställning har visat sig över tid eftersom nålförare är ett av de oumbärliga instrumenten vid alla typer av operationer. Vi går in i en framtid där robotar kan programmeras för att utföra uppgifter med mycket högre precision och hastighet jämfört med människor. Medicinska robotar inom kirurgi har varit på frammarsch senaste årtionden på grund av goda kliniska resultat. Ett steg i denna riktning skulle vara att skapa en lösning som gör det möjligt för en robot att greppa nålföraren. Syftet med denna studie var att utveckla ett gripdon som möjliggör för en kollaborativ robot att utföra suturering med hjälp av en av de vanligaste typerna av nålförare som används vid operation. Design metodiken Double Diamond användes för att beskriva design processensen. Det valda metoderna i de fyra för definierade faser var: 1) Discover: Observation, MoSCoW Prioritization, Brainstorming, Choosing a Sample, Fast Vissualization, 2) Define: Assessment criteria, 3) Develop: Physical Prototyping, 4) Deliver: Final testing and Evaluation. I första fasen, Discover, formulerades kliniska och tekniska krav. I den andra fasen, Define, definierades flera designidéer som skissades på papper, varav den med den högsta poängen valdes i Assessment criteria. I fas tre, Develop, modellerades den valda designidén i kartong, lera och silikon samt 3D-printades. Flera designiterationer gjordes baserat på feedback från kliniska och tekniska experter vilket resulterade i en slutlig prototypdesign som godkändes av experterna. I fas fyra, Deliver, testades och utvärderades den slutliga prototypen. Observation av fem realtids och en videoinspelning av kirurgiska ingrepp på riktiga patienter gjordes. Insikterna som gjordes bekräftades med kirurgerna som genomförde operationen och sammanfattades i 24 kliniskt viktiga observationer som var relevanta för gripdon designen. Noggrann realtids observation av robotens rörelsemönster samt analys av det tidigare utformade gripdonen och intervju med en robotingenjör sammanfattades i tio tekniskt viktiga observationer. Observationerna användes för att formulera kliniska och tekniska krav som gripdons designen strävar efter att uppfylla, följt av prioritering av kraven och designegenskaper enligt MoSCoW-metoden och brainstorming kring hur tidigare gripdons design kan förbättras. För att begränsa designutmaningens omfattning valdes en av de fem typer av nålförare som används vid barnhjärtkirurgi i Lund genom metoden Chossing a sample. För att ytterligare karakterisera de kliniska och tekniska kraven upprättades en testbänk för att definiera och mäta kraftvektorer som appliceras på nålföraren när den hålls av en kirurg under suturering. De radiella krafterna i sex riktningar vinkelrätt mot nålförarens spets varierade från 1,6 N till 3,8 N. Den axiella kraften längs nålförarens längd var 7,6 N mot spetsen och 8,4 N mot bakänden. Medurs och moturs vridmoment längs nålförarens längdaxel var 0,2 Nm respektive 0,18 Nm. Dom definierade kraven låg till grund för skisser av flertal gripdondesign idéer enligt Fast Visualization. Dessa skisser användes sedan i Define fasen för att kommunicera designidéer med kirurger samt robot- och produktutvecklingsingenjörer. Den mest lovande idén togs till Develop fasen där fysiska prototyper togs fram i kartong, lera och silikon samt genom 3D-printning. Förbättringspunkter hittades under testning och återkoppling med intervjuer tillsammans med kliniska och tekniska experter. Designåtgärder baserat på återkopplingen gjordes för att komma fram till den slutliga prototypen. Slutlig testning och utvärdering av den slutliga prototypen genomfördes i Deliver fasen. Gripdons designen kunde hantera större belastningar än den mänskliga kirurgen i alla stabilitetstester. Böjning av nålföraren uppstod dock i testerna med gripverktyget till skillnad från testerna med kirurgen var föremål för stabilitetsprovning. En barnhjärtkirurg och en robotingenjör poängsatte uppfyllnadsgrad av de kliniska respektive tekniska kraven efter att slutlig testning av gripdonet utförts. Uppfyllnadsgraden poängsattes från 1–5 där 1 var dålig, 3 tillfredsställande och 5 utmärkt. Gripdonets slutliga prototyp uppfyller alla kliniska och tekniska krav på nivå 4 respektive 3–5. Designmetodiken som användes i denna studie var användbar för utvecklingen av gripdon som uppfyller både de kliniska och tekniska kraven. Detta tyder på att denna metod kan användas i liknande designutmaningar inom området mellan medicinsk och teknisk innovation. Gripdonet uppfyllde kraven även om ytterligare förfining i materialvalet, ytterligare testning och undersökning av regulatoriska aspekter krävs innan den kan användas under riktiga operationer i operationssalen.

In today's digital age, efficient field operations are crucial for success across various industries. However, usability challenges are often overlooked in favour of functionality, hindering seamless task execution in the field. Evado, a company specialising in software solutions for field workers, offers the Evado Mobile Flow application to help streamline their operations. Yet, as demands evolve and complexities increase, usability shortcomings become increasingly apparent. Therefore, this master's thesis aims to optimise field operations by redesigning Evado Mobile Flow to enhance usability and efficiency. Critical usability challenges within the current interface are identified, such as usage difficulties for new users, followed by a comprehensive redesign process using the double diamond design approach. The methodology encompasses discovery, definition, development, and delivery phases, ensuring an effective outcome. The project started with the discovery and define phases, focusing on understanding user needs and interface limitations. Various techniques, including literature review, benchmarking, navigation flowchart, interviews, observations, hierarchical task analysis, and personas, provided valuable insights into the interface and user understanding, which helped to understand the existing problems. Next up was the development and delivery phase, which employed ideation methods such as braindrawing and scampering to generate a broad range of improvements and ideas. These were evaluated through a Pugh matrix and refined through iterative prototyping. The winning design proposal then underwent usability tests, focusing on task completion rates, clicks, user satisfaction, and potential improvements. The initial round of testing on the first prototype prompted a redesign, addressing newly identified usability challenges and introducing new functionalities aligned with evolving user needs. After a redesign, the final design underwent a second usability test and a system usability scale, yielding a usability score of 88.8 and recommendations for future iterations. Recommendations for future work and iterations include exploring the redesigned interface's long-term impacts on field operations and opportunities for further enhancement. This thesis emphasises the importance of user-centred design in developing effective digital solutions and provides a framework for similar endeavours in mobile interface design. / I dagens digitala ålder är effektiva fältoperationer avgörande när det gäller framgång inom olika industrier. Trots det förbises användbarhetsutmaningar ofta till förmån för funktionalitet, vilket förhindrar effektivt utförande av uppgifter i fältet. Evado, ett företag specialiserat på programvarulösningar för fältarbetare, erbjuder applikationen Evado Mobile Flow för att hjälpa till att effektivisera denna typ av verksamhet. Ändå, i takt med att kraven utvecklas och komplexiteten ökar, blir bristerna i applikationens användbarhet alltmer uppenbara. Därför syftar detta examensarbete till att optimera fältoperationer genom att omforma Evado Mobile Flow för att förbättra användbarheten och effektiviteten. Kritiska användbarhetsutmaningar inom den nuvarande gränssnittet har identifierats, som svårigheter att använda gränssnittet som en ny användare, och följts upp med hjälp av en omfattande designprocess. Vilket har skett med hjälp av double diamond design processen. Metoden omfattar de olika faserna av upptäck, definiera, utveckla och leverera, vilket säkerställer ett effektivt resultat. Projektet inleddes med faserna upptäck och definiera, vilka fokuserade på att förstå användarnas behov och gränssnittets begränsningar. Olika tekniker, inklusive litteraturundersökning, benchmarking, navigationsflödesschema, intervjuer, observationer, hierarkisk uppgiftsanalys och personas, gav värdefulla insikter i gränssnitt- och användarförståelse, vilket hjälpte till att förstå de befintliga problemen. Nästa steg var utvecklings- och leveransfasen, som använde idégenererings metoder som braindrawing och scamper för att generera ett brett utbud av förbättringar och idéer. Dessa utvärderades genom en Pugh-matris och förfinades genom iterativa prototyper. Det vinnande designförslaget genomgick sedan användbarhetstester, med fokus på godkänt genomförande, klick, användarnöjdhet och potentiella förbättringar. Den initiala omgången av testning som skedde på den första prototypen ledde till en iteration i designen, vilket adresserade nya identifierade användbarhets-utmaningar och introducerade nya potentiella funktioner som kan anpassas till användarnas behov. Efter denna iteration genomgick den slutliga designen ett andra användbarhetstest samt metoden system usability scale, vilket resulterade i ett betyg på användbarheten, på 88.8 poäng och nya rekommendationer för framtida iterationer. Rekommendationer för framtida arbete och iteration på denna applikation kan vara att utforska det omformade gränssnittets långsiktiga påverkan på fältoperationer och möjligheter till ytterligare förbättringar. Detta examensarbete betonar även på vikten av användarcentrerad design i utvecklingen av effektiva digitala lösningar och tillhandahåller därmed en ram för liknande utveckling inom mobilgränssnittsdesign.

Master of Landscape Architecture / Department of Landscape Architecture/Regional and Community Planning / Mary C. Kingery-Page / Over time the conventional design process has minimally evolved from Hideo Sasaki’s staged-design process, one of the original models of landscape architectural design process (Murphy 2005, 50; Sasaki 1950, 35). Different types of conventional design process, as it is called in this study, incorporate more stages, devoting more time to each; however, the stages are still completed in an exact order due to the focus on problem solving. The lack of encouragement for personal creative thinking through an individual creative process within the conventional design processes used today is apparent in both the profession and the education of landscape architects today. Because a creative process does not simply solve problems but encourages creative thinking throughout design, the profession would see greater generation of new ideas if landscape architects began to embrace a more creative process, as identified by Graham Wallas in the 1920s (Lawson 2006, 149-150; Herrman 1995; Goswami and Goswami 1999, 43-44). Interviews with highly creative, or avant-garde, landscape architects, such as Thomas Balsley, Claude Cormier, Mikyoung Kim and Peter Walker, and assumedly creative artists helped to provide answers to primary research questions: How does the design process of avant-garde landscape architects compare to the assumedly creative process used by artists? And how can the conventional landscape architectural design process be reframed to incorporate more creative thinking in landscape architectural practice and landscape architectural education? Using a grounded theory approach, in-depth, open-ended interviews were completed with eight subjects. Initial coding themes were based upon broad categories from literature review. Substantial coding and analysis of interviews to find the creative and conventional design processes and characteristics of creativity for each subject resulted in emergent themes and sub-themes from the interviews. Analysis matrices were developed to document commonalities and discrepancies between initial themes from literature review and emergent themes from interviews. Conclusions on findings from initial and emergent themes include:highly creative landscape architects employ non-linear, creative processes throughout design, confidence in personal creativity is imperative to creative thinking, and landscape architectural programs should allow students flexibility and creative license for developing personal design processes.

Les travaux présentés proposent une méthode appelée GeoSpecif. L'objectif de cette méthode est de proposer une assistance à la recherche de spécifications géométriques. Cette méthode doit, de plus, s'intégrer au cycle de conception. Ces travaux sur la spécification sont basés sur deux outils : le Torseur des Petits Déplacements, pour la simulation, le langage GeoSpelling, pour l'expression de la spécification. Le produit est modélisé par deux vues, une première géométrique (correspondant aux pièces) et une seconde architecturale (correspondant à l'assemblage). La méthode peut être décomposée en plusieurs étapes : éprouver le mécanisme nominal afin de vérifier la robustesse de la conception, générer une architecture avec défauts afin de trouver des solutions pour gérer les mécanismes hyperstatiques, mettre en place une spécification, sur les éléments influents, exprimée dans le langage GeoSpelling. Un mécanisme industriel a servi d'application à ces résultats, il s'agit d'un manchon d'hélicoptère Eurocopter®. La méthode permet ainsi de passer d'une simulation des variations géométriques des pièces grâce à l'outil Torseur des Petits Déplacements à une spécification exprimée dans le langage GeoSpelling. Elle peut être appliquée sur toute sorte de mécanisme hyperstatique, sans changer son comportement, grâce à l'introduction des interfaces à l'issue de la définition de la séquence de mise en position. Elle propose une assistance au concepteur à toutes les étapes de la conception. La spécification qui résulte de la simulation est, grâce à cette méthode, plus proche du besoin fonctionnel des pièces.

Len Lye was born in Christchurch, New Zealand, in 1901. Lye was an avid enthusiast of kinetic sculpture and experimental film. In 1965 Lye built a prototype for a kinetic sculpture called Blade that he intended would be a much larger work. In 1996, Dr. Shayne Gooch of the University of Canterbury embarked on a research contract that saw the fruition of Lye’s Blade at a scale previously unachieved. This work was given the name Big Blade. This thesis provides a study into the maximum realisable scale of Blade using technology and materials available today. A new pivoting clamp design is tested and assessed using a small scale Blade sculpture built at the University of Canterbury and used as a test rig. Advancements in technology, material availability and manufacturing techniques lead to a comprehensive fatigue study of the new clamp design. Stresses are measured at the critical stress location in the blade material and a new maximum economic scale of Blade is suggested. The new sculpture requires a blade material that measures 10024mm x 1080mm x 22mm. The visible blade length is 8424mm. The new sculpture is called Giant Blade. A critical aesthetic component for Len Lye’s performance of Blade is the mode shapes formed by the blade material. Specifically, the second and third bending modes (Lye’s single and double harmonic) and the first torsional bending mode (Lye’s shimmering frequency). These frequencies are calculated using the new pivoting clamp design to ensure that these sections of the performance are maintained in Giant Blade. An important requirement of the new sculpture drive mechanism is the capability to reduce the amplitude of shuttle oscillation dynamically during Blade performances. This capability allows bending stresses in the blade material to be reduced in the third bending mode of vibration without halting the performance to adjust the shuttle oscillation amplitude. Four dynamically adjustable variable stroke mechanisms are presented and compared using the methods of Pahl and Beitz. A suitable mechanism for Giant Blade is selected and a proposed arrangement for the new sculpture is provided. An embodiment design is presented for Giant Blade. This embodiment design consists of a new pivoting clamp design and the proposed variable stroke mechanism. Further work includes the design of a mechanism to support the ball and wand assembly.
