    The Unseen Lifecycle: The Role of Design in Preventing Unutilised Household Products
    (2024) Isaksson, Vera; Wang, Junying; Chalmers tekniska högskola / Institutionen för industri- och materialvetenskap; Chalmers University of Technology / Department of Industrial and Materials Science; Strömberg, Helena; Nilsson, Karin
    The United Nations has highlighted the urgent need for a sustainable lifestyle to address environmental degradation and resource depletion. Households play a critical role in achieving these goals by adopting more sustainable consumption behaviours. By researching the different parts of a product's journey, we can begin to understand how products become unutilised. This thesis explores the personal relationship people have with their products, aiming to find the underlying factors that contribute to products becoming unutilised. Through user studies, the research examined the trajectories of products moving within the household and how people's actions may lead to unutilised items. The project seeks to provide knowledge about why and how products become unutilised and will highlight different ways design can prevent products from becoming unutilised and contribute to creating sustainable consumption patterns. We present an activity system that focuses on how people, products and environment, i.e. the house, interact together. Within the system, tensions are formed between contradicting motives, activities, goals and outcomes. The result of the project is a concept portfolio with seven concepts that address different tensions within the system and illustrate how design can prevent products from becoming unutilised. Ultimately, this research contributes to the ongoing discourse on sustainable consumption and offers practical insights for designers seeking to promote the recirculation of products.

    Scenario Building as a Tool for Future-Oriented Product Design
    (2024) Arfvidsson Nilsson, Daniel; Sjödin, Alicia; Chalmers tekniska högskola / Institutionen för industri- och materialvetenskap; Chalmers University of Technology / Department of Industrial and Materials Science; Strömberg, Helena; Strömberg , Helena
    The world is constantly changing and adapting to technological innovations and societal events. Since we cannot predict the future with certainty, designing for the future poses a significant challenge. Despite this, there is limited research describing how scenario planning can be used in future-oriented design. This project aims to explore how future scenarios can serve as a creative tool for design. Conducted in collaboration with Volvo Group, the project focuses on the design of trucks and trailers as a case study. This project employs an exploratory approach, integrating Futures Thinking and Design Thinking. Information was gathered through expert interviews and trend research, reading from a wide variety of sources. The subsequent trend analysis focused on a selected set ofmegatrends and catalysts, which provided the foundation for scenario construction. Drawing inspiration from the Swedish Energy Agency’s report, Four Futures, its scenario format was used as a template. Using methods such as "If this is true, what else is true?", the relationships between trends were mapped and explored. Finally, three scenarios were constructed, which then served as the basis for developing two design concepts. The concepts were then evaluated by a focus group of designers at Volvo Group. To evaluate the scenarios they were compared against a set of criteria: plausibility, consistency, distinctness, comprehensibility, time and effort involved and degree of integration. The results showed that the scenarios met the criteria but revealed another weakness in the design process. The focus group called for a design method that more thoroughly incorporates the scenarios into the designs. To further explore how to utilise scenarios in design work, the next step could be to investigate the best methods for transitioning from scenario to product. Specifically, this involves finding ways to develop designs that fully integrate and reflect the information contained in the scenarios.

    Investigating Vehicle-to-grid from a User-centric Perspective
    (2024) Evertsson, Alice; Nylander, Alexandra; Chalmers tekniska högskola / Institutionen för industri- och materialvetenskap; Chalmers University of Technology / Department of Industrial and Materials Science; Strömberg, Helena; Strömberg , Helena
    The rising energy demand from an increasingly electrified society reliant on renewable energy sources poses a significant challenge to the electricity grid, causing imbalances and peak demands. A supplement to grid expansion is the use of energy storage technologies such as batteries to stabilise the grid. Today, passenger vehicles are parked 96 percent of the time, and with the growing number of electric vehicles and the trend towards larger batteries, they present an excellent opportunity for energy storage. These potential forms the core of vehicle-to-grid. Previous research focuses on technical aspects and stakeholder collaboration but lacks the perspective of electric vehicle users. Hence, this thesis aims to explore electric vehicle users’ willingness to adopt bidirectional charging as a mean to redistribute energy consumption and avoid peaks in energy demand. The project entailed four distinct phases: initial research, user research, design sprint 1 and design sprint 2, involving literature studies, user studies, concept development and concept evaluation. The project approach combined the divergent and convergent phases of the double diamond framework with a co-creation approach, involving a consistent user group throughout the entire project in order to provide deeper insights into the user perspective of vehicle-to-grid by allowing for the progressive development of ideas and feedback. The project yielded in three key results: an identification of five potential vehicle-to-grid user archetypes, four key design principles for user adoption of vehicle-to-grid, and a design proposal of a vehicle-to-grid solution fulfilling the needs and requirements of the identified user archetypes. It could be seen that the intrinsic motivation of the user archetypes towards V2G differed based on their drivers and blockers, affecting how they perceived the use of a V2G solution. The four key design principles, simplicity, transparency, customisation, and system integration, was developed as a framework to enable the design of a V2G solution catering to all of the identified user archetypes. Furthermore, the thesis demonstrates the feasibility of designing a solution for diverse user groups, paving the way for widespread adoption of V2G technology. Additionally, understanding the user-centric perspective is crucial for future dissemination and adoption, an aspect this thesis contributes to significantly due to limited existing research in this area within the V2G domain.

    Robotiquette in Scandinavia
    (2024) Andersson, Emrik; Takvam, Filip; Chalmers tekniska högskola / Institutionen för industri- och materialvetenskap; Chalmers University of Technology / Department of Industrial and Materials Science; Bligård, Lars-Ola; Ekman, Fredrick
    This master thesis, which was conducted in collaboration with Merphi, set out to investigate what needs and requirements exist from dining customers and restaurant employees, to create acceptance for restaurant robots within a Swedish context. The research was performed from multiple perspectives, including a literature study, semi-structured interviews, and observations, all of which generated valuable insights into the acceptance of restaurant robots in Sweden. The analysed material from the research phase was then translated into a first iteration of design guidelines to be further refined through an iterative design process. The design process consisted of six design sprints, each focusing on a predefined set of guidelines for the development of sub-solutions that later could be combined into a restaurant robot concept. This design process resulted in refined design guidelines and a robot concept showcasing an exemplified translation of the design guidelines. Further analysis of the design process led to the development of a novel suggested design approach. This approach aims to further facilitate the development of robots by providing a clear structure for transforming a service that has previously been perceived by the users to be centred around a human, into one centred around a robot. Finally, a smaller focus group consisting of expert robot designers was used to evaluate and identify further improvements in the design guidelines and the suggested design approach. All the resulting insights are thought to help designers in the future develop robots that are to be accepted in a Swedish restaurant setting. The results were put into a web application showcasing the design approach, the design guidelines, the restaurant robot concept, and how they relate to each other to further aid future service robot designers.

    Designing a Premium Dishwasher Opening Experience
    (2024) Liew, Caroline; Lycken, Klara; Chalmers tekniska högskola / Institutionen för industri- och materialvetenskap; Chalmers University of Technology / Department of Industrial and Materials Science; Bligård, Lars-Ola; Bligård, Lars-Ola; Johansson, Mikael; Carlehed, Jon
    Today, users see dishwashers as uninteresting products with little change over a longtime. To increase and improve users’ experience and perceived quality, a premiumdishwasher opening experience was studied and designed, with regards to dishwashing and interior kitchen trends. Methods used to achieve this were interviews, user studies, benchmarking of kitchen interiors and dishwashers and a workshop. Trends and findings from benchmarking kitchens and dishwashers and the user study were used to create design guidelines. Examples of trends and findings are an increase in colours, rounded shapes, milled-in LED strips and the users considering how well the dishes are cleaned, the most important aspect of dishwashers. The final concept is a light and scent combination with a milled-in colour-changing LED strip one third of the way into the dishwasher, a functional spotlight moving with the baskets and lights behind the basket handles to improve the perception of cleanliness and premium experience.
