Conceptual design of a power supply unit for transmission bearing monitoring based on TRIZ

To solve the problem of low power supply efficiency of the bearing monitoring device in the transmission, we used functional analysis and trimming methods from TRIZ(Theory of Inventive Problem Solving).By analyzing the role relationship between various components and constructing a functional model, we identified the cause of the problem through functional structure analysis. We then proposed an optimized solution using magnetic induction to convert mechanical energy into electrical energy and deliver it to the bearing monitoring device through magnetic power supply. This solution was developed using the four trimming strategies.
