Some of products have to return to the popular phenomenon, such as polaroid , headphone, scanner, etc. This paper discusses successful cases. The definition of success means that the old technology is reapplied to the new product. And the product is still on the market and will have a complete product life cycle. Exploring the factors that successfully returned to the market in the case. which is about the historical background,social phenomena and human factors etc. This paper investigates the research theory,with the design viewpoint into the Product Strategy and Technology Life Cycle. Develop product design strategies for outdated technology returning to the market by analyzing past cases and interviewing relevant professional：（1）Renewing the value of technology and resonating with consumers.（2）Design-based, followed by technology.（3）Transfer the original target, from the professional to the popular.（4）Different from the purpose of the original product then generate new demand.（5）Simplify features for more convenience. Finally, these strategies apply to the outdated technology. Then create new products, this process is provided to enterprises with outdated technology as a transformation reference.創新產品設計策略技術生命週期InnovationProduct Design StrategyTechnology Life Cycle
