Innovation of Car Seat Construction Using TRIZ-Based Tool: Function-Oriented Search

The paper deals with the search and design of suitable security solution of an innovated construction of a car seat. The problem consists in the use of flexible reinforcements of the seats, which replaces an origin sheet metal. On this reinforcement the comfort seat cushion is placed on which a passenger sits. This reinforcement is pre-stressed with a certain force, but this force is inadequate during the crash. Consequently, the passenger can dip in the seat, which is very dangerous. Therefore it is necessary to use a suitable mechanism, for pre-stressing the reinforcement by a desired force in the case of crash. New TRIZ-based tool—Function-Oriented Search (FOS) method was utilized to find appropriate solutions. With its help several analogous solutions, which are applicable for this problem, were found. In the paper the advantages and disadvantages of these proposals are discussed, including the proposed optimal solution.
