Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional power generation methods are used for battery-less electronic devices, then the devices can operate without batteries, but the power generation efficiency is low and reliable power conversion from environmental energy is not achieved
Solution Approach 1:
The patent employs a movable magnet that can be dynamically repositioned within the chamber to optimize its distance from the core, thereby dynamically adjusting the magnetic flux linkage and improving power generation efficiency under varying conditions
Solution Approach 2:
The system utilizes periodic movement of the magnet relative to the core through collision mechanisms, creating periodic changes in magnetic flux that induce continuous electrical current in the coil, enabling sustained power generation
2Power
If a magnet is placed in a chamber with a core and coil to generate power, then electrical current can be produced through magnetic flux changes, but the mechanism to sustain magnet movement is insufficient
Solution Approach 1:
The magnet is designed to move itself through collisions with chamber walls or components, utilizing its own kinetic energy and magnetic interactions to sustain movement without requiring complex external actuation mechanisms
Solution Approach 2:
The system incorporates vibration or collision-based movement mechanisms that cause the magnet to oscillate or collide with the chamber, creating sufficient magnetic flux variation to generate electrical current in the coil
3Productivity
If environmental energy is converted into electrical power using magnetic flux changes, then battery-less devices can be powered, but the conversion efficiency and output stability are inadequate
Solution Approach 1:
The system optimizes parameters such as magnet strength, core material properties, coil winding configuration, and chamber geometry to maximize magnetic flux linkage and improve power conversion efficiency while maintaining stable output
Solution Approach 2:
The patent incorporates feedback mechanisms that monitor the magnetic flux and electrical output, adjusting the magnet position or movement characteristics to maintain stable and efficient power generation under varying environmental conditions
