The Strategy Research and Application of Product Function Innovation

The objective of product design is to meet some function demand of people and the goal of product innovation is to realize product function innovation. Based on this, the paper proposes a new mode of product function decomposition and a strategy method system facing product function innovation, which contains function conflict solved strategy, function relation established strategy, function removed strategy, function replaced strategy and potential-function inspired strategy. The six strategies can assist designers in product function innovation effectively based on analyzing the interrelationship between each sub-function of the product. Finally, a concrete example of the agricultural miniature rototiller is demonstrated the usage of the six strategies, which illustrates the effectiveness of these innovation strategies.
