The service quality of healthcare is highly related to the health and satisfaction of the patient, hence, how to enhance the service quality of healthcare and how to reduce patient's complaint is always very important topic. To improve the service quality of healthcare, contradictory phenomenon is usually encountered in traditional problem solving process, hence, TRIZ has been successfully applied in the engineering and management fields through innovative thinking, through the setup of contradiction matrix and through systematic solving of specific problem.However, there are very few studies in applying TRIZ in the improvement of the service quality of healthcare, in this study, through the use of TRIZ, solution for the improvement of the service quality of healthcare has been developed for individual case. The result shows that TRIZ can indeed solve the special problem of the individual case through the development of generalized solving procedure by aiming at the special problem of the individual case, hence, it can provide a very important reference for solving problems for people providing healthcare service.
