Abstract In todays highly competitive market environment, product must satisfy customer needs and be creative.Aiming at this problem,this paper researched customer needs and creativity strategy,and developed a method of product innovation by systematically integrating QFD(quality function deployment) and SIT(systematic inventive thinking). By mining the customer needs of target product and using the house of quality in QFD to analyse the customer needs,we can obtain the relationship between technology characteristics and rapidly get a creative solution in allusion to the negative correlation in technology characteristic pairs with the SIT theory.The design of track lifting and lining machine effectively demonstrated the proposed method and process．
