Proposition of Establishment of the New Life Stage by the Development of 4 Wheels' Walking frame with Sleds

Abstract

This development has double-sided. The development of a new good is one. Based on the patent, the authors developed product acting on a patent. A development of 4 wheels' walking frame with sleds by the grant of the New Energy and Industrial Technology Development Organization (NEDO) shows this one surface. A method development or a use development is the other. It is the example of this surface that Henry Ford made the vehicle which was a region of the hobby till then the popular transportation and carriage device. Probably, a business-model patent in recent years will also be the same. As a method development or a use development to aim at us, the author proposed to change the myth of "people walk on 3 legs with a cane" from the Greek era to "people walk on 6 legs used a walking frame". This is a great transformation of the way of thinking. We described the necessity and possibility, and the feasibility which the present study of 4 wheels' walking frame with sleds induced about the possibility of a use development.
