Proficiency in the application of design research methods is a basic competency that student researchers need to master. During the learning phase, experienced researchers demonstrate various design research methods for student designers to understand and practice. At present, there are a large number of literatures and books that introduce the definition of different design research methods and give relevant practical examples. Moreover, student researchers still have confusion about the process of the research method in the early design, and lack a complete understanding of design research thinking and processes. This article will take the topic of sustainable laundry as an example, based on the core research theme of the impact of the use of laundry bags on environmental sustainability by Chinese graduate students studying in the UK in their daily lives, and demonstrate the complete design research ideas and process from 6 modules. This design form emphasizes authenticity, interactivity, and humanization. In terms of authenticity, experiential design strives to create a scenario as realistic as possible, constructed with as real questions and materials as possible, to maximize the satisfaction of users' real needs. In terms of interactivity, experiential design adheres to the standard of users' spiritual enjoyment and physical pleasure, strengthening interaction with users. In terms of humanization, experiential design focuses more on the fun of furniture products, emphasizes meeting the deep spiritual and cultural needs of users, and endows furniture products with more functional value in a form that is more in line with the human body structure, thus integrating with users.
