Development and application of intelligent home control system based on TRIZ theory in single live wire environment

Based on TRIZ theory, this paper addresses the problem that the smart home products do not work in the case of single live wire. By analyzing the problem, applying tools such as little creature method, object-field model, technical contradiction, functional tailoring and knowledge base to get a technical solution to the problem, and evaluating the solution to get the optimal solution, we finally design a smart home control system that can work in the single live wire environment. The smart home product can be used in a single live wire environment, and it is convenient to replace the old product in place only.
