Multi-Purpose Concept of Design: A Sustainable Strategy in Addressing the Widespread Redundancy of the “White Wedding Gowns” in the Ghanaian Culture
Publication . Ibrahim, Haruna; Romãozinho, Ana Mónica Pereira Reis de Matos; Silva, Fernando José Carneiro Moreira da
Sustainable best practices and material culture are at the forefront in this 21st century, and as a result, sustainability and circularity have become very crucial for global industrial growth and development, and the clothing and textile industry cannot be left out. The clothing and textile industry is considered the second largest contributor to environmental pollution, after the oil industry, and this is due to the fashion industry's adherence to a linear economic system. The alarming rate of this disposable behaviour in the clothing industry requires the adoption of a multi-purpose design concept as a strategy to curb this design stance that may have the potential to extend the life of clothing, encourage sustainable consumption, minimise greenhouse gases and facilitate the transition to a circular economy. The wedding dress is perhaps one of the most common clothing items to be discarded prematurely or become redundant in many wardrobes once the wedding ceremonies are over, meaning that it has become a one-of-a-kind outfit regardless of the time, money and other resources invested in its acquisition. This consumer behaviour is attributed to the lack of innovative design thinking and also the failure to incorporate the needs and values of clothing consumers through the adoption of a co-design strategy. This study is qualitative in nature and therefore employs a mixed-methodological approach, i.e., a combination of interventionist and non-interventionist research methods, to address the study objectives. The thesis has two main objectives (1) to give wedding dresses an extended life within the wedding culture in Ghana by exploring on the one hand the multi-purpose concept of design and on the other hand, product development through co-design with wedding dress wearers; (2) propose a new conceptual model and produce a sample wedding dress through a sustainable prototype to be tested and validated.

The Impact of Electrification in Automotive Design for Light Vehicles
Publication . Calhamar, António Maria Sancho Mègre Queimado; Monteiro, João Manuel Milheiro Caldas Paiva; Baptista, Júlio Londrim de Sousa Cruz
This dissertation aims to explore the impact of electrification in automotive design. Pivotal historic events that helped shape the contemporary automobile are crucial, as they not only offer a view into varying trends across automotive history but also show how the electric vehicle was once the dominant choice through market share in the early 1900s. This subject matter also elicits interest on the importance of manufacturers, brands and how they adapt to innovations, trends, legislation and consumer interest. The presentation of a case study comparison between electric and internal combustion powered vehicle granted a framework to observe the contrast between two means of propulsion, and what they entail. Subsequently, challenges and opportunities in regard to electric propulsion were researched and analysed. The conclusion being that weight, price, energy density, inadequate infrastructure and lack of versatility as a result of time-consuming charging still plague the electric vehicle, however, home renewable energy, ease of use, solid state batteries, superior packaging, smaller drivetrain volume, absence of mechanical connections between components, lower maintenance needs and running costs, higher efficiency, lower center of gravity, and increased interior space all provide opportunities for electric vehicles to affirm themselves in the highly competitive automotive sector.
