Výzkum využití technologie rozšířené reality při práci konstruktérů / Untersuchung des Einsatzes von Augmented-Reality-Techniken auf die Arbeitsprozesse in der Konstruktion

Holešovský, Jiří January 2018 (has links)
This diploma thesis summarizes the principles of augmented reality and the possibilities how this technology could be used in the work of designers. The thesis also describes the possibilities of realizing an augmented reality (AR) program and compares specific AR devices. The process of the designer's work is also analyzed, and concepts how AR could be used during the work process were designed. One concept of use has been implemented. It was a visual-ization of new constructed parts of autonomous robot, developed in project "FOLLOWme". The designers will use this program to detect collisions between parts and verify overall design of the robot.

Are building design rating systems effective towards the goal of sustainability in the design and construction of public and private buildings and how will new energy performance and sustainable design requirements affect the professional liability of building design professionals?

Transue, Samuel D. 01 January 2011 (has links)
The following paper will explore the future of sustainable building practices as it relates to building design rating systems and whether building design rating systems are effective in conserving energy and resources in the construction of new buildings. This paper will begin by highlighting some of the general principles behind sustainable design practices, and the challenges of determining if building design rating systems are utilized effectively towards the goal of sustainability. In addition, the paper will highlight issues specific to ongoing litigation in Gifford v. U.S. Green Building Council and allegations made within the lawsuit that question the methodology and efficacy of building design rating systems. How political and ideological influences have propelled sustainability practices into the mainstream, and to what extent government is and should be involved in regulating building design rating systems will also be explored. Lastly, how will new energy performance and sustainable design methodologies, which are now being required in the law, affect the professional liability of building design professionals in the future?

The role of a design engineer in safety of building projects

Vermeulen, Bernard 04 1900 (has links)
Thesis (MEng)--Stellenbosch University, 2014. / One of the causes for money to be wasted on construction sites is accidents. The reason is that an accident on site is an unplanned event typically relating to the loss of production or the loss of life. Many industry stakeholders and role players have focused on construction health and safety and to improve this area of concern; however, construction health and safety are not significantly improving. Construction still continues to contribute a large number of fatalities and injuries relative to other industry sectors. During the construction phase, poor construction health and safety performance is attributable to a lack of management commitment, inadequate supervision, and a lack of health and safety training and - systems. Health and safety systems do not only include excellent health and safety management on site, but rather an integrated approach on health and safety issues from the conceptual design phase by all stakeholders participating. This integrated approach includes the design done by the engineer. The inspiration behind this research is the question of whether South African Engineers design buildings safe for construction. The lack of knowledge by engineers with regard to construction processes, the lack of health and safety enforcement in the engineering offices and construction sites, and whether engineers adhere to safe design principles is the subject of investigation in this research. Therefore, this research aims to investigate the role of the design engineer in the safety of building projects. Specifically, it investigates to what extent the design engineer can contribute to site safety, and to what extent this is actually taking place. The Construction Regulations states the engineer can be appointed to act on behalf of a client and should share any information that might affect the health and safety of construction employees with the contractor. By means of a literature study, the investigation of case studies and the investigation of questionnaires to which a percentage of South African engineers responded, this research identified the information that should be shared by the design engineer with the contractor. The information can be shared by indicating hazardous activities or - locations on the actual drawings. Information can also be shared by specifying and reminding the contractor of certain health and safety hazards in the health and safety specifications of the building project. Although the Construction Regulations state that the safety hazards associated with most construction processes are the responsibility of the contractor, it will be beneficial for the safety of the employees if the engineer also consults the contractor on the hazards identified by him or her during the early design stages. Early collaboration between the engineer and contractor is also beneficial for the safety of construction employees. The result is an integrated approach towards safety hazard identification and mitigation. Having adequate knowledge with regard to construction processes allows the engineer to be aware of possible safety hazards. This will result in the correct information to be shared with the contractor and incorporated into the early design phases of the project to ensure a healthy and safe working environment. The study shows that a percentage of South African engineers have a lack of site experience, a lack of safety training, a lack of knowledge with regard to the content of the Construction Regulations, and a lack of knowledge with regard to construction processes. These shortcomings can be detrimental to site safety.

Kostnadseffektiv design och framtagning av flexibel innerförpackning åt elektronikprodukter / Cost efficient design and development of flexible packaging interior for electronics

Berglund, Sofie January 2013 (has links)
Abilia utvecklar, tillverkar och säljer tekniska hjälpmedel till personer som antingen har en fysisk eller psykisk begränsning som påverkar deras vardag. För att dra ner på kostnaderna och få en bättre enhetlighet vill Abilia att ytterförpackningarna ska standardiseras samt att ett flexibelt inrede som ska kunna anpassas till många av företagets produkter utvecklas. En förstudie lade grunden för projektet där många olika områden och metoder undersöktes. De existerade förpackningarna utvärderades, deras och produkternas livscykel kartlades varpå det framgick vilka som var projektets huvudanvändare. Dessa intervjuades och en kravspecifikation kunde sedan fastställas. Förstudien resulterade i att det fanns två grupper av produkter som lösningen måste kunna anpassas till. Lösningen måste även vara flexibel både för produkterna och för dess tillbehör. Hjälpmedelscentralerna som visade sig vara projektets huvudanvändare hade krav att lösningen skulle vara hållbar och ge förpackningen en strukturerad insida. Koncept genererades med hjälp av en praktisk idégenerering som resulterade i olika former och konstruktioner. Konceptval genomfördes genom diskussion med personal från Abilia samt genom en viktad konceptvalsmatris. Projektet resulterade i ett flexibelt och hållbart inrede i två lösningar. En produktpresentationsdel som har en konstruktion med nedvikbara flikar som gör det möjligt att kila fast produkter oberoende av storlek samt en flexibel tillbehörsdel som både kan regleras i höjdled och sidled. Lösningen uppfyller kraven från kravspecifikationen och har verifierats av experter inom området att den fungerar i verkliga situationer. Materialet i lösningen är det bäst anpassade för funktionen och är även det material som har lägst miljöpåverkan av de som undersöktes i projektet. / Abilia develops, manufactures and sells aids for people who have either a physical or mental limitations that affect their everyday lives. In order to save money and get a better uniformity Abilia want to standardize the packaging and develop a flexible interior that can be adapted to many of the company’s products. A pilot study laid the foundation for the project where many different areas and methods were examined. The existing packages were evaluated, and their and the products lifecycles were identified and that made it clear who the projects user was. They were interviewed and a product specification could be established. The pilot study resulted that it was two groups of products and the solution must be able to adapt to both. The solution must also be flexible to the products and their accessories. The Hjälpmedelscentralerna turned out to be the users in this project and they had requirements that the solution must be sustainable and provide a more structured inside of the packaging. Concepts were generated with a practical idea generation that resulted in different forms and constructions. The concept selection was made after discussion with the staff from Abilia and through a balanced concept selection matrix. The project resulted in a flexible and durable interior in two parts. A product presentation part which has a design with folddown flaps that allows the product to get stuck no matter which size and a flexible accessory which can be adjusted both vertically and horizontally. The solution fulfills the requirements from the product specification and has been verified by expert that it would work in real situation. The material in the solution is the best suited for the function and it is also the material with the lowest environmental impact of those surveyed in the project.

Transportation demands : of chilled and frozen groceries

Österberg, Viktor January 2019 (has links)
Today focus on the environemnt is bigger than ever before. UN writes in their climate agenda that they by 2030want to cut the food waste per capita in half. There are strict regulations today regarding how food needs to betransported and stored, but as soon as the consument takes, for example, milk from the frigde at a store there areonly a few guidelines about how the product should be stored. If a chilled or frozen product is not kept insidethe range of the given temperature, a microbilogical growth will begin. This leads to that the food goes bad or,in worst case, that the consumer gets poisoned. There is a change happening today in how the consumers shoptheir food and more focus is layed upon the customer to handle their grocery shopping by themselves. This project focuses on developing a solution that will help the consumer to keep their food at the right temperatureduring an extended period of time. The project is carried out in Stockholm during 20 weeks in collaborationwith IKEA of Sweden in Älmhult. The target group in this project is IKEA’s broad customer group.With help from a Human Centered Design process this project goes through the three phases; inspiration,ideation and implementation. The project has been formed with interaction through workshops with differentexternal actors like users and focus groups. The ideation resulted in four simpler concepts that verged in to twothrough external decision making with supervisors from IKEA of Sweden. During the project, the prototypeshave been used together with users to evaluate the usability of the concepts. The result consists of two concepts; Behålla and Blåsa, that are aimed to meet two different users that hasbeen identified through surveys and interviews. Behålla is a smaller product that is target towards the user thatbrings food with them to work or school, also to those who buys less groceries at the store. Blåsa is, in contrastto Behålla, a bigger product that is targeted towards the customers that buys a bigger set of chilled and frozengroceries. Additionally four color variations has been created to offer IKEA alternative executions. These conceptsare visualized with renderings through Adobe Illustratior. With these concepts IKEA can enlarge theirsustainability profile and offer their customers two new products to keep their chilled and frozen foods cold. / Fokus på miljön är idag större än någonsin. FN skriver i sin klimat agenda att de till 2030 siktar på att halveramatsvinnet per capita. Idag finns det hårda regleringar om hur livsmedel ska transporte-ras och förvaras, menfrån den sekund konsumenten tar ut exempelvis ett mjölkpaket ur kyldisken finns det bara få riktlinjer om hurprodukten bör förvaras. Om en kyld eller fryst produkt inte hålls inom det angivna temperaturspannet skerdet en ökning i den mikrobiologiska tillväxten i livsmed-let. Detta leder i sin tur att matvaran blir dålig eller, ivärsta fall, att konsumenten blir förgiftad. Idag sker det också en förändring i hur konsumenterna handlar sinalivsmedel och allt större vikt läggs på att konsumenten för sig själv ska genomföra sitt köp. Detta projekt fokuserar på att utveckla en lösning som ska hjälpa konsumenten att hålla sina matvaror tempereradeunder en viss tid. Projektet är genomfört i Stockholm under 20 veckor i samarbete med IKEA ofSweden i Älmhult. Målgruppen i detta projekt är den breda kundgrupp som IKEA erhåller. Med hjälp av enanvändarcentrerad designprocess går det här projektet genom de tre designfaserna; inspiration, idégenereringoch slutligen implementering. Projektet har formats av interaktion genom workshops med olika externa aktörerså som användare och fokusgrupper. Idégenereringsfasen resulterade i fyra stycken enklare koncept somavgränsades till två genom extern beslutsfattning med handledare från IKEA of Sweden. Under projektets gånghar prototyper använts tillsammans med användare för att evaluera användarvänligheten hos koncepten. Resultatet består av två stycken koncept; Behålla och Blåsa, som är ämnade att möta två olika kundgrupper somhar identifierats genom enkäter och intervjuer. Behålla är en mindre produkt som riktar sig till de användaresom tar med sig matlåda till jobbet eller skolan samt till dem som köper färre matvaror i butiken. Blåsa är, ikontrast till Behålla en större produkt, skapad med fokus på de kunder som köper fler kylda och frysta matvaror.Utöver detta har fyra färgvariation skapats av produkterna för att erbjuda IKEA alternativa utföranden. Dessakoncept är visualiserade med hjälp av renderingar som har gjort i Adobe Illustrator. Med dessa koncept kanIKEA utöka sin hållbarhets profil och erbjuda sina kunder två nya produkter för att hålla deras kylda och frystamatvaror kalla.

Integrering av iläggsskiva i matbord / Integration of a table leaf to a dining room table

dos Santos Cardoso Olsson, Johan, Karlsson, Marie January 2009 (has links)
Denna rapport har skrivits i samband med ett examensarbete i integrerad produktutveckling. Rapporten genomfördes under den avslutande kursen på designingenjörsprogrammet vid högskolan i Skövde 2008 i samarbete med företaget Lundbergs Möbler AB i Tibro. Rapporten redogör för designprocessen där en lösning för att integrera företagets iläggsskivor tas fram för deras matbord. Rapporten skildrar projektets olika delar från förstudie till slutligt koncept. Projektets inledande förstudie påvisade framförallt hur konkurrenternas lösningsprinciper ser ut, hur hanteringen av dagens iläggsskiva ser ut och dess hanteringsproblem samt ergonomin kring hanteringen av iläggsskivan. Det som framkom i förstudien låg därefter som beslutsunderlag för den fortsatta produktutvecklingen. Dessa områden gav en klarhet i om projektet var genomförbart och vidare vilka fysiska begränsningar och möjligheter projektet hade inför det fortsatta produktutvecklingsarbetet. Med den nya kunskapen bakom sig inleddes idégenereringsfasen. Här användes flera olika idégenereringsmetoder för att generera en mängd nya idéer. Idéerna utvecklades sedan för att därefter resultera i tre olika koncept. Förslagen pressenterades därefter för företaget som gick igenom koncepten och beslutade vilket koncept vi skulle arbeta vidare med. Efter företagets val använde vi oss av konceptvalsmatriser i den fortsatta produktutvecklingen för att nå fram till den bästa slutprodukten. Till sist framställdes en CAD-modell av det slutgiltiga konceptet och en teknisk prototyp tillverkad utefter denna modell. Prototypen gav en uppfattning om hur väl mekaniken hos konceptet fungerade. / This report covers the result of a final thesis in Product Design Engineering, in partial fulfillment of the Product Design Engineering program held at the University of Skövde. This report describes a project that was carried out in conjunction with Lundbergs Möbler in Tibro. The objective of the report is to convey the design process of integrating a table leaf into a Lundbergs dining table. The report will also present the product as it goes through the whole design process from idea, materializing in a prototype and concluding to a final concept/product. A pre study displays an overall view of product handling and current market solutions of today's table leaves, where handling issues and ergonomics of table leaf usage is illuminated. The information from the pre study has determined the feasibility of the project and has also been utilized as a foundation for a project specification upon which further product development can commence. With the information from the pre study as a foundation, the idea generation phase could begin. Different creativity methods are used to bring forth several innovatory ideas that can be utilized in improving the product. These ideas were improved on and evaluated to result in three different concepts. These concepts were then presented to Lundbergs Möbler who went through them and decided which concept to go forward with. Conceptual matrices were then used to steer further development of the product. When the concept was developed to satisfaction a CAD-model and a physical prototype has been built from the specifications and measurements from the CAD program. The prototype demonstrated the function of the mechanism that had resulted from the project. The prototype that resulted from integrating a table leaf in a dining table gave a functional mechanism that could be taken into production.

Modular Locking System to RBS Cabinet

Almqvist, Josefin, Sundelius, Emma January 2013 (has links)
Radio base stations contain equipment which enables the use of cell phones all around the world. ERICSSON is developing these stations and everything connected to the area, such as electronics, software and hardware. In a new project ERICSSON plans to make their hardware modular, to satisfy all their customers around the world even if their preferences differ. The task that was given to us was to develop a modular locking system to the radio base station cabinets.The concept was developed in an integrated working process that focused on a user centered final product. The process included the definition of the problem, preliminary studies of areas which are connected to the problem and a summary of the demands that the customers mediated in a list of requirements. The idea generation generated lots of ideas that later on were developed into different concepts. The concepts were evaluated before the final decision was made together with ERICSSON.The final product is a lifting handle connected to a rod and latch system, which already existed. A new mechanical function was created to make the new handle function with the old system. The locking system is modular and it is possible to choose which way to lock the handle, with a cylinder lock or a padlock. Only one module, the cylinder in the middle, needs to be switched to get the other solution. The other parts are the same; this makes the product modular. The lift handle is an entire new design, developed in the project.

Wax-accessory for cross-country skiers : Development of a wax-bench that collect waste

Larsson, Emelie January 2018 (has links)
This is a master thesis report for MSc in Industrial Design Engineering at Luleå University of Technology. It is a development project where a wax-bench for cross-country skiing has been developed. The wax-bench have been developed to facilitate the clean-up for the user and to gather all wax-accessories at one place. In this report the entire project can be followed from start to finish, how the requirements were found, who is the user, what should the product handle and how was the ideas ge- nerated. The final result is a wax- box that is vacuum formed and folded in the middle. In the box there are adjustable profiles to place the ski on and an adjustable attachment part in the center that attaches to the skis binding. The box acts as a collector of the waste that is produced when waxing skis, and as storage of waxing accessories when not in use. How to install the accessory in the box is not yet determined, but the idea is to develop a specific bag that fits perfectly in the wax-box and includes all the usual accessories. This bag should then be taken out when you wax and put back in the box after complete the waxing. / I den här rapporten kan man följa ett examensarbete för civilingenjörsprogrammet Tek- nisk Design på Luleå Tekniska Universitet. Projektet består av ett utvecklingsarbete där en vallabänk för längdskidåkning har utvecklas. Vallabänken har utvecklats för att underlätta städningen för användaren och för att samla alla vallatillbehör på en och samma plats. I den här rapporten kan man följa hela projektet från start till mål, hur kraven hittades, vem är användaren, vad ska produkten klara av och hur genererades ideer. Det slutgiltiga resultatet är en valla-låda som är vakuumformad och viks ihop på mitten. I lådan finns det justerbara profiler att placera skidan på samt ett justerbart fäste i mitten som fäster i skidans bindning. Lådan fungerar som uppsamlare av skräpet som bildas när man vallar skidor och som förvaring av vallatillbehör när den inte används. Hur valla-tillbehöret ska placeras är ännu inte fastställt men tanken är att det ska utvecklas en specifik väska som passar in perfekt i valla-boxen och som har plats för alla de vanliga tillbehören. Denna väska ska sedan gå att plocka ur när man vallar och placera tillbaka i boxen efter utförd vallning.

Minimization of Noise and Vibration Related to Driveline Imbalance using Robust Design Processes

Al-Shubailat, Omar 17 August 2013 (has links)
Variation in vehicle noise, vibration and harshness (NVH) response can be caused by variability in design (e.g. tolerance), material, manufacturing, or other sources of variation. Such variation in the vehicle response causes a higher percentage of produced vehicles to have higher levels (out of specifications) of NVH leading to higher number of warranty claims and loss of customer satisfaction, which are proven costly. Measures must be taken to ensure less warranty claims and higher levels of customer satisfactions. As a result, original equipment manufacturers (OEMs) have implemented design for variation in the design process to secure an acceptable (or within specification) response. The focus here will be on aspects of design variations that should be considered in the design process of drivelines. Variations due to imbalance in rotating components can be unavoidable or costly to control. Some of the major components in the vehicle that are known to have imbalance and traditionally cause NVH issues and concerns include the crankshaft, the drivetrain components (transmission, driveline, half shafts, etc.), and wheels. The purpose is to assess NVH as a result of driveline imbalance variations and develop a tool to help design a more robust system to such variations.
