Applying the TRIZ Systematic Innovation Method to Improve Short Circuit Devices

Abstract

A short circuit protector will quickly switch off power in case of an overload or short circuit fault in order to quickly isolate or eliminate the fault. This research uses the contradictions matrix of the TRIZ innovation theory and 40 innovation principles to innovate and improve the product. The improved short circuit protection employs an optical coupler for detection, and the control circuit is triggered synchronously at the moment when a short circuit happens so as to cut off the power and sound a buzzer alarm. The response time is 14 milliseconds, which is faster than the response time (0.1 seconds) of tripping a fuse circuit breaker so as to achieve circuit protection.

Accelerating preliminary low-carbon design for products by integrating TRIZ and Extenics methods

“…Petkovic et al 41,42 apply TRIZ creativity enhancement approach to get creative conceptual design ideas for robotic gripper and joint. Lin et al 43 adopt the TRIZ innovative method to improve short circuit devices. TRIZ method is considered a critical tool in cleaner production, especially in chemical engineering, to minimize industrial waste and emissions by means of enhancing the efficiency of the use of energy and materials.…”
