This design first discovered the pain points of garbage classification from life. Through the data review and related paper reading I acquired a deeper understanding of the recycling processes of kitchen waste. On this basis, I used competing product analysis method, questionnaire survey method, user interview method to excavate the market and users. Based on the KANO model, the high-quality elements of a food waste garbage bin are sequenced in the order of importance. I further interpreted these elements by integrating network user comments and entries. After determining the target user, I used the brainstorming method, user behavior model method, and user journey map method to summarize the design points based on the market and user information. The product visual elements are extracted by copying illustrations, combined with gamification functions, and integrated into the product. The internal and external forms of the product are scrutinized to form a product design plan, including design of appearance, ergonomics, structure and function. As well as the details of the plan, such as the user manual and scene concept related to the design plan. The final product is a two-by-one household dual-category trash can, helping users to happily deal with domestic kitchen waste in a gamified situation.
