Study on the Usefulness of TRIZ in the Development of a Rehabilitation Assisting System

TRIZ, which is a theory of inventive problem solving, has been widely recognized in areas where the technical system needs to be enhanced since it examines the situations that may result in contradiction and endeavors to overcome such contradiction. Especially in developing rehabilitation assisting systems for the rehabilitation of the disabled and patients, it is expected that the application of TRIZ will be very useful because they are in a condition of contradiction where they need to take exercise although they cannot move for themselves.

Thus, this study aims to re-interpret existing rehabilitation assisting systems in view of TRIZ, look into the usefulness of TRIZ, attempt to enhance existing rehabilitation assisting systems in application of TRIZ, and thus demonstrate the usefulness of TRIZ. To this end, this study re-interprets cases of existing rehabilitation assisting systems in light of such problem solving tools of TRIZ as 40 inventive principles, analysis of system functions, laws of technical system evolution, Su-Field analysis modeling and Ariz. In addition, a current problem of a ceiling hoist system, which is adopted for the people with disability to lift and transfer them between wheelchair and bed or toilet seat, are analysed by ARIZ and reached to possible solutions.

It is expected that this approach will demonstrate the usefulness of TRIZ in terms of development and enhancement of rehabilitation assisting systems as well as become a good model for the utilization of TRIZ in actual development fields.
