The post-epidemic era is a profound reflection of "social pathology", and from the designer's point of view, it is a "surgical" precise landing. The epidemic has made "home" no longer a mere living space, but has been forced to superimpose multiple functions such as offices, schools, gyms, cinemas and shelters. The forced superposition of this role exposes the defect of "single function" of traditional product design, and also forces people to rethink the necessity of portability, versatility and modular design. The epidemic is not only a challenge, but also an opportunity to promote product design innovation, especially in the home scene, how to design to meet the diverse needs of people, to create a work and fitness, both learning and entertainment composite space, has become a core issue for designers to solve. This exploration is not only the optimization of the existing way of life, but also a positive response to the harmonious development of the future society.
