A Process of Innovation: Technological Development in Wood Construction

Lock, Samuel E. 19 March 2012 (has links)
This thesis explores the use of small diameter, round timber in the construction of lightweight gridshell structures. The project intention is to develop a simple and accessible construction method, based on locally available material that embraces a diverse range of technology. The design is developed using a material based approach, which first explores the behavior and limits of the material through testing at full scale. This information is used in a rapid prototyping process of scale modeling which focuses on material and construction sequence to develop a structural system. Using available materials as a design parameter, the work is an exploration of how the gridshell system can be adapted to the specific context of rural Nova Scotia. This design method is explored through the design of a craft school at the Ross Creek Centre for the Arts in Ross Creek, Nova Scotia, Canada.

Material av restprodukter från hampa till produktdesign / Material of By-Products FromHemp for Product Design

Gezavati, Daniel January 2023 (has links)
This paper is a research through design that answers the question: How can the by-products from hemp production be utilized to create a sustainable material for product design?Hemp is the commercial crop that sequesters carbon dioxide most effectively in the world, but large amounts of bast fibers and hurd emerge as by-products ater cultivation for seeds, flowers, and leaves. These by-products can be difficult for farmers to manage as they require space for storage and often must undergo a lengthy production process before they can be converted into products. The by-products of the hemp industry must be managed properly in order for the whole production chain to be considered sustainable.This paper explores theories like Upcycling and Design for Sustainable Development, so sustainability is always considered while managing these by-products. The research methodology encompasses interviewing six experts within the field of product design and hemp to comprehend the perceived difficulties and possible soultions. Material mapping, user tests and material tests are performed to develop a material from hemp fibres and stoneware clay. Additional user tests, market analysis, requirement list,braindrawing and prototypes are then implemented to ascertain what products that could be made from the hemp clay and how these shall be designed. These methods resulted in the contribution of design for the paper: HampaLampa (HempLamp), a hemp-lampfoot made with hemp clay and linseed oil paint as a surface treatment. / Studien är en forskning genom design som besvarar frågeställningen: Hur kan restprodukter från hampaproduktionen utnyttjas för att skapa ett hållbart material till produktdesign? Hampa är den komersiella grödan som absorberar koldioxid mest effektivt i världen, men det uppstår stora mängder restprodukter i form av fibrer och vedämnen när hampa odlas med frön, blommor eller blad som primärprodukt. Dessa restprodukter är svåra för lantbrukare att hantera då de tar stor plats att lagra och ofta behöver genomgå en lång tillverkningsprocess för att kunna användas i produkter. Hampaindustrins restprodukter behöver hanteras för att produktionskedjan skall förbli hållbar. Studien utforskar teorier som upcycling och design för hållbar utveckling, hållbarhet prioriteras ständigt när processen att använda restprodukterna utforskas. I Metodkapitlet intervjuas sex experter inom produktdesign och hampa för att inse vilka svårigheter och möjliga lösningar de känner till. Materialkartläggning, användartester och materialtester utförs för att utveckla ett material från hampafibrerna och stengodslera. Ytterliggare användartester, marknadsanalys, kravlista, braindrawing och prototyperutförs sedan för att utforska vilka produktersom hade kunnat skapas av hampalera och hur dessaskallutformas. Dessa metoder resulterade i designbidragetförstudien: HampaLampa, en hampa-lampfot skapad av hampalera med en ytbehandling av linoljefärg.

DESIGN FOR DISASSEMBLY - A CIRCULAR APPROACH

Pervez, Wajiha 01 January 2017 (has links)
As the world becomes increasingly aware of the need to better care for the environment, innovative business models are helping to counter the damage of the fast fashion system - a phenomenon in the fashion industry whereby production processes are expedited in order to get new trends to the market as quickly and cheaply as possible. Designing products with a focus on their renewability can shift the product-consumer relationship. The closed loop concept of a “circular economy” is emerging as a viable and promising solution to the current linear business model. This study explores the possibilities of a more mindful approach to systems of production and consumption through material explorations using plastic from water bottles, paper from old newspaper and magazines, and fabric leftovers from pattern making within a circular economy. It considers the generative and renewable approaches in redefining how fashion engages with the components and raw materials of the industry. The research demonstrates a circular approach to the production of hospitality accessories in an effort to develop new intersections between products, materials, and consumers. The accessories are designed using discarded, reformulated denim–an abundant and underutilized byproduct of the fashion industry­–to reduce waste that currently occurs every time hotel chains and airlines produce disposable giveaway products from new materials.
