TESTIn this paper, a solution that can address the chattering phenomenon of a car’s wiper was derived. Thus, TRIZ was used. TRIZ consists of several tools. Among them, a tool that models and analyzes situations where problems occur is Substance-Field Analysis (SFA). SFA is a diagrammatic representation of the system in question, as it is currently operating. SFA is easy to understand, but the clues for finding solutions are limited to the current situation. Moreover, it is supplemented so that the changed state of the substance constituting the system in question, that is, the factor of time, can be reflected in the SFA. To reflect the changed state of the substance constituting the system in the SFA, additional items will be tabulated. This item table was then applied to derive a solution for a chattering car wiper. In addition to the solution to the current situation, another solution that considered changing the substance over time was also derived. Among the solutions to wiper chattering, an appropriate solution must be reviewed based on evaluation criteria according to the development or production conditions of the wiper. Thus, no appropriate solution was selected in this paper.
