摘要

With the improvement of medicine and health care, the elderly are facing the dilemma of independent mobility Because the life expectancy of people in Taiwan has greatly increased. And the population structure of this society has been ageing rapidly. At this time, the power scooter is the most important action aids in life, so the design of safety of power scooters is a vital factor, especially in the initial launch, out of control scooters likely to sudden unintended acceleration (SUA). In order to prevent all possible accidents, it is essential to ensure that the scooter is in a safe state when traveling along a route. In order to deal with these problems above, our study proposes a Triz-based theory by redesigning the speed controller system. Firstly, use the method of The Systematic Innovative Thinking defines the potential problems and key disadvantage. Then, take use of Contradiction matrix and 40 Inventive principles to target solution. Finally, by using Trimming tool to delete unnecessary elements. These methods can maintain functional integrity of power scooters and increase the safety of people who take the vehicle. The study improve speed controller system of power scooters and add PWM and Soft-starter to correct the problem of sudden unintended acceleration. Power scooters traffic accidents caused by improper handing have declined greatly. Provide the elderly a kind of safe assistive devices for independent mobility.
