지속 가능한 제품 디자인을 위한 파티나의 활용에 관한 연구
Background : Affluence in the mass production-mass consumption era has resulted in the fast consumption of products. Fast consumption leads to product waste with short life cycles, and these short life cycles have raised environmental concerns. Sustainable design has thus emerged to cope with these environmental challenges. Despite the concerted efforts in sustainable design and, further, sustainable consumption, the product life cycle has remained short. This study is an attempt to address sustainable consumption by forming ongoing relationships between users/consumers and products. We are proposing the concept of patina in product/product-service design. Methods : We critically review the literature concerned with patina in various discip-lines in and around patina including design, history, literature and anthropology to apply the concept of patina to product design. We utilize a case study as a method to explore the concept and the applications of patina in design. Various cases dealing with patina have been analyzed. Based on the above analysis, we suggest various types of patina and the implications drawn from each type of patina. Results : Products have recently been short lived long before their due life cycles. These short life cycles at least partly hinge on the durability of the products’ relationship with their users. To enable products to have a longer life cycle, efforts should be made to reinforce the above relationship in addition to the concerns about eco-friendly materials, logistics and recycling. Patina, as a way of suggesting an emotionally durable design and product, can contribute to this relationship by forming user attachment to a product. Conclusion : Patina enables a product to be more valuable to its user as time goes by. The understanding and application of patina can help to prolong the life of a product and is a critical element for designing a sustainable product. This study is by its nature exploratory, thus needing more thorough analysis from cases and expert interviews to offer further practical implications to the field of sustainability including sustainable design.
