摘　　要：文章基于相似性科学理论,分析了从成本利润率的角度为所设计产品选择功能的可行性,研究在产品设计中如何从相似产品的众多功能中,选择出能够使新产品获得最好经济效益的功能,以及如何选择出每个所用功能的最大经济效益的特性差异,并通过实例详述了该方法的计算步骤,验证了此种方法在实际产品设计中的可靠性和实用性,为利用相似技术进行产品开发、创新提出了一种新思路、新方法。Based on the theory of similarity science, the feasibility of using the cost-profit ratio to choose functions for the product that is being designed is analyzed, and how to choose the best economic effect functions for the new product from the functions of many similar products and how to choose the suitable differentiable characteristic of every function of the new product to get the best economic effect are studied. The calculation process is elaborated by citing an instance ,and the reliability and practicability of the method in practical design is proved. The presented method provides a new idea and a new way for the design of new products using similarity technology.
