Abstract—This paper aims to provide a systematic analysis by applying TRIZ to reduce the consumption of household electricity, and nonetheless it does not demote the quality of living. TRIZ tools such as defining engineering system, function analysis, cause and effect chain analysis and contraction matrix are applied in order to discover some feasible and elegant solutions to alleviate the problem. Findings revealed that the problems of high household electricity consumption are owing to the wastage of electricity due to the ignorance behavior, poor layout design of the house, stand-by mode "leak" of electrical appliances and high electricity consumption from old electronic products. The root causes and contradictions are solved by applying contradiction matrix, and inventive principles are recommended, i.e., segmentation, copying, preliminary action, dynamization, intermediary, and parameter changes. Therefore, it can be concluded that TRIZ is a systematic and innovative tool in problem solving. |
