Based on the theory of product service system, three product service systems including product-oriented, use-oriented and result-oriented product service systems for the elderly are analyzed. The latter two types of product service systems are more welcomed by the society and users, and have broader market prospects. In the design of a product service system for the elderly, a behavior model of service participants is established in the early stage, service elements are designed in accordance with rules in the middle stage, and sustainable system solutions are created in the later stage. The sustainable product service system design leads new lifestyles and consumption patterns of the elderly, including the suitable work in context, the social care in the system, the more convenient travel in collaboration and the new learning methods in reconstruction learning. The research finds that, in order to make the elderly have suitable work, social care, more convenient travel, and new learning methods, it is necessary to provide convenience for the elderly's lives with the sustainable product service system design that the elderly are willing to accept and is easy for them to use.
