UP : Grow up with your furniture

Lin, Mu-En January 2021 (has links)
In Taiwan, even though we have sets of desks and chairs in different sizes for school children, due to the inconsistency of purchases and the number of students in the year, many students did not have the opportunity to use desks and chairs that fit their height. In such an environment, students have incorrect postures, cannot concentrate in class, and begin to neglect or even destroy the tables and chairs they use. In this project, I designed the furniture to be adjustable in height. It solves the inconvenience of school procurement and provides students with a more comfortable learning environment. Besides, I also introduced the concept of "Wood education" to cultivate students' understanding of Taiwan's native natural resources and develop the feeling of cherishing the furniture that students use from assembling their wooden furniture.

Implementing Design For Automatic Assembly : A recommendation on how to implement andapply DFAA at Company Y

von Yxkull, Filippa January 2018 (has links)
The need to work with Design for Automatic Assembly (DFAA) has been widely recognizedin the literature. However, the implementation of DFAA is not clearly defined. Therefore, thepurpose of this master thesis is to investigate and contribute with knowledge of how DFAAshould be implemented into an organization, such as Company Y.Several interviews have been conducted to establish a current state analysis, to receive anunderstanding of the current problems at Company Y and how to address them. Abenchmarking study was conducted, where the three companies Ericsson, Company X andScania were interviewed. All three companies have successfully implemented DFA and wereinterviewed with the purpose to obtaining their best practices. The study also included an earlyimplementation of DFAA, where a software based DFA2-method created by Eskilander (2001)was tested on a current product and a new developed design concept at Company Y. Based onthis a recommended workflow of the evaluation could be attained.Based on the empirical gatherings several recommendations of how DFAA should beimplemented into the organization could be made. The study highlights that DFAA should beapplied as early as possible in the product development process. The DFA2-method should beutilized at product level to facilitate concept selection and at part level to make theproducts/modules suited for automatic assembly, before the design is “locked” and before aphysical prototype is created. The departments that should be working with DFAA includesindividuals from production, design quality and purchasing. However, once DFA becomesrooted in the company, more functions in the company’s supply chain will become affected.This means that more functions might need to be included in the work of DFAA. Finally, thestudy includes a decision model, in which the decisions are based on the measurable valuesreceived from the DFA2-method. / Behovet av att arbeta med Design for Automatic Assembly (DFAA) har uppmärksammat ilitteraturen. Däremot har implementeringen av DFAA inte blivit tydligt definierat. Syftet meddetta examensarbete blir således att undersöka och bidra med kunskap om hur DFAA skaimplementeras i en organisation, så som Företag Y.Flera intervjuer har genomförts för att upprätta en nuvarandeanalys för att få förståelse för derådande problemen hos Company Y och hur dessa ska hanteras. En benchmarkingstudiegenomfördes, där de tre företagen Ericsson, Company X och Scania intervjuades. Alla treföretagen har framgångsrikt implementerat DFA och har intervjuats med syftet att erhålla derasbästa praxis. Studien innefattar även en tidig implementering av DFAA, där enmjukvarubaserad DFA2-metod skapad av Eskilander (2001), har testats på en aktuell produktoch ett nytt utvecklat koncept på Company Y. Baserat på detta kunde ett rekommenderatarbetsflöde av utvärderingen presenteras.Baserat på empiriska studien kunde flera rekommendationer gällande hur DFAA skaimplementeras i en organisation skapas. Studien belyser att DFAA bör tillämpas så tidigt sommöjligt i produktutvecklingsprocessen. DFA2-metoden bör utnyttjas på produktnivå för attunderlätta konceptvalet och på komponentnivå för att göra produkterna/modulerna lämpade förautomatisk montering, detta innan designen är "låst" och innan en fysisk prototyp harkonstruerats. Avdelningar som ska arbeta med DFAA inkluderar produktion, designkvalitet ochinköp. När DFA blir rotad i företaget kommer dock fler funktioner i företagets supply chain attpåverkas. Det innebär att fler funktioner kan behöva inkluderas med arbetet kring DFAA.Slutligen så inkluderar studien en beslutsmodell relaterat till DFAA. Besluten baseras på demätbara värden från DFA2-metoden.

Bee Me and the rest of Nature : Reflecting on our actions through holistically sustainable beehotels engraved with mental strengthealing journaling tools. / Bee Me and the rest of Nature : Reflecting on our actions through holistically sustainable beehotels engraved with mental strengthealing journaling tools.

Gons, Cornelie Amber January 2023 (has links)
This project is about creating for/with humans and the rest of nature. The design is composed of five holistically sustainable beehotels with mental strengthealing journaling tools engraved into them. These beehotels have shifted away from anthropocentrism and are instead geared towards the needs of the pollinators, they are fully created from the forest they are made for. And the journaling exercises have been created to encourage self-exploration to recognize our own strength and build emotional intelligence. The entire design is a way to reflect on our actions.

Kreislauf vor Produkt

Schmidt, Lea 29 June 2022 (has links)
Gemäß dem ‚Circular Gap Report 2020‘ wird weltweit nur 8,6 % des Materials zirkulär genutzt. Die Tendenz ist sinkend: Zwei Jahre früher waren es noch 9,1%. Die Weltwirtschaft benötigte im Jahr 2019 insgesamt 100,6 Gigatonnen Material (de Wit et al., 2020). Trotz großer politischer, gesellschaftlicher und wirtschaftlicher Aufmerksamkeit rund um die Thematik einer dringend benötigten nachhaltigeren Wirtschaft zeigt sich, dass wir mit der Materialzirkularität insgesamt nicht auf Kurs sind. Wie kann die Materialzirkularität aus der Perspektive von Designer:innen – als Akteur:innen, die gemäß Literatur ‚over 80 % of all product-related environmental impacts‘ verantworten – verbessert werden? (Graedel et al., 1995)

Genom design öka medvetenheten kring, samt underlätta spårningen av menstruationscykelns känslomässiga påverkningar : För ökad kontroll över kvinnlig hälsa / Through Design, Increase Awareness, and Facilitate Tracking Of, the Emotional Effects of the Menstrual Cycle : To Increase Control Over Women’s Health

Alatalo Nordin, Lovisa January 2023 (has links)
Denna studie är en designbaserad forskning som utforskar frågeställningen: Hur kan en genom design öka medvetenheten kring och underlätta spårningen av menscykelns känslomässiga påverkningar? Tillsammans med underfrågan: Hur kan en produkts design bidra till minskat stigma kopplat till menstruation? Detta görs genom att belysa hur ett användarcentrerat tankesätt och co-design metoder kan användas i syfte att designa för tabubelagda ämnen. Projektets syfte var att undersöka hur produktdesign kan stötta kvinnor i att enklare spåra och förstå sig på sin hälsa ur ett helhetsperspektiv. Detta för att främja ökad kontroll, välbehag och hälsosammare liv för kvinnor; samt i längden bidra till design för social hållbarhet. För att undersöka forskningsfrågan har metoderna expertintervju, marknadsundersökning och co-design workshop använts. Co-design workshopens utformning är ett exempel på hur teorin Troubling design har influerat metodutförandet. Detta eftersom teorin problematiserar tillämpningen av användarcentrerad design i relation till kvinnlig hälsa samt menar att design för kroppsliga upplevelser behöver omprövas i form av att ändra från ett problemlösningsfokus till att fokusera på kvinnans erfarenheter och därmed ej se den menstruerande kroppen som ett problem som går att “lösa”. Utfallet av expertintervjuer, marknadsundersökning och co-design workshop analyserades och utifrån detta skapades en kravspecifikation som blev grunden för designprocessen. Resultatet av designprocessen och därmed även studiens slutgiltiga designförslag som besvarar forskningsfrågan blev en brädspelsinspirerad kalender med tillhörande känslospårare och cykelvisualisering. Slutsatsen blev även att stigma effektivast motverkas genom normalisering av spårning samt ökad kunskap hos icke menstruerande. / This study is a design-based research that explores the question: How can one, through design, increase awareness and facilitate tracking of the emotional effects of the menstrual cycle? Together with the sub-question: How can a product’s design contribute to reduced stigma linked to menstruation? This is done by highlighting how a user-centered mindset and co-design methods can be used in order to design for tabooed topics. The purpose of the project was to investigate how product design can support women to more easily track and understand their health from a holistic perspective. This to promote increased control, well-being, and healthier lives for women; and in the long run contribute to design for social sustainability. To examine the research question, the methods expert interview, market research and co-design workshop have been used. The design of the Co-design workshop is an example of how the theory Troubling design has influenced the method execution. This because the theory problematizes the application of user-centered design in relation to women’s health and emphasizes that design for bodily experiences needs to be reconsidered in the form of changing from a problem-solving focus to focusing on the woman’s experiences and thus not seeing the menstruating body as a problem that can be “solved”. The outcome of expert interviews, market research and co-design workshop was analysed and based on this a requirement specification was created which became a starting point for the design process. The result of the design process and the study’s final design proposal which answers the research question became a board game-inspired calendar with enclosed emotion tracker and cycle visualization. The conclusion was further that stigma is most effectively counteracted through the normalization of tracking and increased knowledge among non-menstruating people.

Return on Investment Analysis for Implementing Barriers to Reverse Engineering and Imitation

Knight, Darren C. 21 April 2011 (has links) (PDF)
Reverse engineering (extracting information about a product from the product itself) is a competitive strategy for many firms and is often costly to innovators. Recent research has proven metrics for estimating the reverse engineering time and barrier and has shown that products can strategically be made more difficult to reverse engineer, thus protecting the innovator. Reverse engineering, however, is only the first phase of attempting to duplicate a product. Imitating – the process of discovering how to physically reproduce the performance of the reverse engineered product in one or more of its performance areas – is the second and final phase. This thesis presents metrics for the time and barrier to imitating and shows how they can be joined with reverse engineering metrics to estimate a total time and total barrier to duplicate a product. As there is a cost associated with the design of barriers to reverse engineering and in imitating it is important that a return on investment analysis be performed to ensure a profitable endeavor. Details of such an analysis are presented here. To illustrate the methodology, two case studies are presented. The first is an analysis of KithcenAid's Stand Mixer. The second is an analysis of a cantilevered "L-beam" that has been structurally optimized under four conditions to achieve a specified mechanical performance. Additionally, anecdotal solutions to creating barriers to reverse engineering and imitating are discussed throughout.

Produktivitetsanalys i praktiken / Productivity analysis in practice

Schilke, Matthis January 2018 (has links)
Behovet av en bostad är ett grundläggande mänskligt behov. Detta behov kan tillgodoses på en rad möjliga sätt. Vi bor med olika upplåtelseformer som hyresrätt, bostadsrätt och äganderätt i olika typer av byggnader. För samhället är det viktigt att det finns tillräckligt med rätt byggnader på rätt plats.Men vad är det egentligen som påverkar vad det är för byggnad som står på en viss fastighet, och hur ser man om det finns potential för utveckling? Svaret ges genom studie av den bakomliggande teorin; en produktivitetsanalys bör utföras. En produktivitetsanalys beskriver en fastighets kapacitet att tillgodose mänskliga behov och ger ett resultat om hur lämplig en fastighet är för en viss typ av bebyggelse. Produktivitetsanalysen är en del av en marknadsanalys och utgör grunden för detta kandidatarbete. Genom en studie av relevant teori avseende marknadsanalys, produktivitetsanalys och bostadsutveckling beskrivs de ingående variablerna i det som påverkar slutgiltig markanvändning i detalj. Vidare studeras hur arbetssätten skiljer sig för större och mindre börsnoterade bostadsutvecklare. Hypoteser ställs upp angående deras respektive förhållningssätt till marknadsanalys.Som lite av en ’plot twist’ görs upptäckten att bostadsutvecklarna inte alls använder begreppet produktivitetsanalys. De har, vad resultatet visar, inte alls något strukturerat sätt att analysera fastighetens egenskaper på. Däremot analyseras de ingående egenskaperna i en produktivitetsanalys även i praktiken, inte bara på exakt samma sätt som i teorin. De större bostadsutvecklarna använder sig av mycket mer standardiserade lösningar än de mindre och utför trots detta, en djupare marknadsanalys. Detta resultat talar emot en av de inledande hypoteserna samt vad som kommuniceras från några av de mindre utvecklarna. / The need for a residence is a basic human need. This need can be met in a number of ways. We live in different types of buildings and they serve different residential needs. For society it’s important that there’s a mix of different types of residential products, in the right place.But what affects what type of residential building that ends up on a specific type of property, and how do you know if there’s a potential to develop the property further? The answer is given by studying the underlying theory; a productivity analysis should be conducted. A productivity analysis describes a property’s capacity to fulfill human needs and tells us how fit a property is for a certain type of use. The productivity analysis is part of a market analysis and constitutes the foundation of this thesis. By studying relevant theory about market analysis, productivity analysis and residential development the input variables, to what affects the use of a property, are identified. The study continues with a comparison between smaller and larger residential developers. Hypotheses are made about their different approaches to market analysis.Like a plot twist, a discovery is made that none of the developers use the term productivity analysis. The results show that they do not work in a structured way with the input variables in a productivity analysis. However, the input variables are analyzed, just not in the same way as in theory. The bigger developers use more standardized construction solutions than the smaller developers and, despite this, they conduct deeper and more thorough market analysis. This result contradicts one of the initial hypothesis and what is communicated by some of the smaller developers.

Ladder to rooftop tents : Product development of a new contractable ladder suited for Thule rooftop tents

Gladh, Gustav, Salomonsson, Robert January 2022 (has links)
This thesis report contains the development of a new ladder specifically designed for needs of the rooftop tent users. The project has been conducted by two students wor- king full time over the duration of twenty weeks with the start in mid-January and is a culmination of their education in industrial design engineering at Luleå university of technology. The thesis is a collaboration with Thule which is a Swedish compa- ny specializing in outdoor and transportation products for the active user. Thule’s largest user base are the occasional users, which uses their products once or twice a year. The current ladder used by Thule today is a telescopic solution that is mainly deri- ved from standards concerning contractable ladders and not specifically made for rooftop tent ladder. Thus, it has a lacking usability and is constructed from many dif- ferent parts which makes it unnecessarily complex and heavy. This has led to Thule wanting this project to explore the possibilities of creating a more weight optimized and cost-efficient ladder that can achieve several lengths ranging from 1,5 to 2,5 meters. This while also making it more user friendly and safe while incorporating the company values. Thus, the mission statement reads: “To create a safe, high quality, and easy to use rooftop tent ladder for the occasion- al, recreational user while reducing weight and complexity” The schedule has followed an iterative process influenced by the phases of design thinking, which is to emphasize, define, ideate, prototype, and finally test. This has helped to solve the complex problems by focusing on the users and their needs. To start this off, an extensive analysis of the market competition, users, Thule, and the current ladder was performed to be followed up with more creative methods as bra- instorming and different stages of sketching, aimed to solve the problems that was found. All of which later was constructed to a feasible concept with computer aided design, prototyping methods, and computer renderings. The result is a new rooftop tent ladder with a sliding design, fulfilling most of the project scope as well as solving other problems found in the first phases. The project has also provided Thule with a full-scale, functional mock-up to prove the concept, as well as some recommendations for future work. / <p>Product patent protected by Thule Sweden.

Slappna av i väntrummet : En studie om hur produktdesign kan stötta patienter i väntrummet innan en gynekologisk cellprovtagning / Relax in the Waiting Room : A Study on How Product Design Can Support Patients in the Waiting Room Before a Gynecological Pap Smear

Dahlgren, Ebba January 2023 (has links)
Att gå på en gynekologisk cellprovtagning är något flera kvinnor tycker är obekvämt. Det upplevs som ett oroligt och obehagligt möte. Studien undersöker därför följande frågeställning; Hur kan produktdesign stötta en stressad/oroad patient i ett väntrum inför en cellprovtagning? Syftet för studien är att förbättra kvinnors väntrums-upplevelser inom kvinnlig vård samt undersöka hur designmetoder och produktdesign kan bidra till framtagandet av en produkt som lindrar användarens stress och orosnivåer i väntrummet inför cellprovtagning. Studien förhåller sig till ett användarcentrerat förhållningssätt som riktar sig till att designa för användaren. Även co-design tillämpas där användaren och designern samarbetar under delar av designprocessen. Denna studies användare är kvinnor i åldern 23–30 år som gör sina första cellprovsbesök.  För att undersöka studiens frågeställning samlades kvalitativ information genom en expertintervju, intervjuer med användaren och workshops med användaren. Dessa metoder analyserades och resulterade i önskemål på fysiska attribut i produkten. Delar av önskemålen togs med i beslut senare i designprocessen. Användarnas problem definierades i metoden Problem Definition. De problem som användarna angav i Problem Definition var att komforten i väntrummet är bristande, väntetiden är oviss samt rastlöshet i väntrummet. Metoden Problem Definition blir studiens grundställning i designprocessen där beslut tas utifrån att lösa de nyssnämnda problemen. Designprocessen bestod främst utav brainstorming, brainwriting och två delar av skissande och prototypande där slutkonceptet framställdes. Studiens frågeställning besvaras genom framtagandet av en interaktiv stol. Stolen syftar till att höja komforten i väntrummet samt uppmuntra till interaktion med användaren och därmed bidra till minskad stress och oro. Interaktionen sker genom att användaren gungar eller vaggar upp och ner när den sitter ner och lutar sig bakåt i möbeln. Slutsatsen är att produktdesign kan stötta en stressad och oroad patient genom att göra denne bekväm, skapa komfort och distrahera från väntetiden i väntrummet. Slutprodukten kom fram till det ovan beskrivna, men fortsatta användartester, funktionstester etc krävs för att framta en stol fullt fungerande för sitt syfte. / Going for a gynecological pap smear is something many women find uncomfortable. It is experienced as an uneasy and unpleasant meeting. The study therefore examines the following question; How can product design support a stressed/anxious patient in a waiting room before a Pap test? The purpose of the study is to improve women’s waiting room experiences in women’s health care and to investigate how design methods and product design can contribute to the development of a product that relieves the user’s stress and anxiety levels in the waiting room before a Pap test. The study relates to a user-centered approach, which focuses on the user’s needs in the design process. Co-design is also applied where the user and the designer collaborate during parts of the design process. The users of this study are women aged 23–30, i.e., women who are attending their first pap smear test appointment. In order to investigate the study's question, qualitative information was gathered through an expert interview, interviews with the user and workshops with the user. These methods were analyzed and resulted in requests for physical attributes in the product. Parts of the requests were included in decisions later in the design process. The users’ problems were defined in the method Problem Definition. The problems that the users indicated during this method were; a lack of comfort in the waiting rooms, unclear waiting times, and restlessness in the waiting room. The Problem Definition method becomes the basis of the study in the design process where decisions are made based on solving the problems just mentioned. The design process mainly consisted of brainstorming, brainwriting and two parts of sketching and prototyping where the final concept was produced. The study’s question is answered through an interactive piece of furniture. The chair aims to increase comfort in the waiting room and encourage interaction with the user, thus reducing stress and anxiety. The interaction takes place by the user rocking the chair up and down while sitting down and leaning back in the chair.  The conclusion is that product design can support a stressed and anxious patient by making them comfortable, creating comfort and distracting from the waiting time in the waiting room. The final product resulted in what was described above, but further user tests, functional tests, etc. are required to produce a chair fully functional for its purpose.
