The common urinal flusher, whether the button switch type or infrared detection induction, due to the water hole in the system by flushing it into the water column outflow, which cannot be evenly distributed in the urinal, resulting in poor cleaning effect.Furthermore, when a large amount of water washed down by the water hole to the urinal, due to the proliferation area of the water column is not enough, but will make the odor.The discomfort caused by toilet, and a lot of punch water will cause waste of water resources.In this study we apply TRIZ Systematic Innovation Method includes: 9-Windows, Contradiction Matrix, and 40 Inventive Principles to solve the problem.The final result shows that the improved urinal flusher devices can be used to adjust the angle to change the spraying angle of the wall of the urinal.There are two features of our design.(1) Water-saving efficiency up to 75%, each flush amount reduced from 1200ml to 300ml (2) Adjustable nozzle angle to increase the rinsing area.
