Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless power supply systems face challenges in minimizing energy loss and maintaining efficient power transmission while allowing for easy and flexible positioning between the primary and secondary coils, especially when the secondary coil is in motion or changing attitude.
Innovation Solution
A wireless power supply system that includes a primary power-supplying coil supported by a machine capable of adjusting its position or attitude to maintain efficient power transmission to a secondary power-supplying coil, which can move, by adjusting their relative positional and attitudinal relationships, allowing for vertical or horizontal alignment as needed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the secondary power-supplying coil is made movable to improve ease of operation, then the ease of operation is improved, but the energy loss increases due to difficulty in maintaining optimal positional relationship
Solution Approach 1:
The first machine is designed to dynamically adjust the position and attitude of the primary power-supplying coil in real-time response to the movement of the second machine, maintaining optimal alignment for wireless power transmission. This dynamic adjustment capability allows the secondary coil to move freely while the system compensates to preserve efficient power transfer, resolving the contradiction between ease of operation and energy loss.
2Loss of energy
If the relative position between primary and secondary coils is fixed to minimize energy loss, then the energy loss is minimized, but the adaptability decreases when the secondary coil needs to move
Solution Approach 1:
The system employs dynamic adjustment mechanisms in the first machine that enable the primary coil's position and attitude to change adaptively. This allows the system to maintain minimal energy loss during power transmission while simultaneously adapting to the movement and attitude changes of the secondary coil, effectively resolving the contradiction between fixed positioning for efficiency and adaptability for movement.
3Loss of energy
If the first machine adjusts the position of the primary coil to maintain efficient power transmission, then the energy loss is reduced, but the device complexity increases
Solution Approach 1:
The first machine is equipped with self-service capabilities including detection units that automatically monitor the position and attitude of the second machine, and control units that autonomously adjust the primary coil's position and attitude in response. This self-service mechanism reduces the need for external intervention and complex manual control systems, thereby managing device complexity while maintaining efficient power transmission and minimizing energy loss.

AI summary
A wireless power supply system includes: a primary power-supplying coil which is a power-supplying coil capable of wirelessly supplying electric power to another power-supplying coil; a first machine that supports the primary power-supplying coil; a secondary power-supplying coil which is a power-supplying coil wirelessly supplied with electric power from another power-supplying coil; and a second machine that can move while supporting the secondary power-supplying coil. The relative positional relationship or the relative attitudinal relationship between the first machine and the second machine can be adjusted corresponding to the movement or change in attitude of the second machine so that a state in which electric power is wirelessly supplied from the primary power-supplying coil to the secondary power-supplying coil is maintained.
