Starting from increasing environmental pollution and resource waste, this paper studies the design of shared express package from the perspective of design ethics. Existing ethical problems of shared express package were analyzed, users' demands for shared express package design were explored through field investigation and user interviews, and through intensive study on emerging problems such as complex delivery and pick-up, inconvenient travel of some vulnerable groups, difficult transportation of heavy goods and package recovery, etc., system solutions based on the express package as a carrier were proposed to conduct rental service of shared express. The new shared package design should follow the design ethics principles of ecology, sharing, and humanization from material selection, functional design, structural design to recycling system to effectively solve such issues as high package costs, recycling difficulties, waste of resources, and poor service systems, and relying on the Internet, big data and other technologies to build the express sharing platform, propose the realization path of ethical value, and ensure accurate and efficient implementation of the shared express package system.
