Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing connection of power feeding coils with a high-frequency power source limits the degree of freedom in layout, necessitating direct connections that require space for power supply wires, which complicates the arrangement of coil assemblies.
Innovation Solution
A coil assembly design incorporating external connecting terminals, resonant capacitors, and busbars allows for electrical connections between adjacent coil assemblies, enabling indirect power delivery and enhancing layout flexibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If each power feeding coil is directly connected with a high-frequency power source using power supply wires, then reliable power supply is achieved, but the degree of freedom of layout is decreased
Solution Approach 1:
The patent merges the power supply function into the coil assembly itself by integrating a resonant capacitor and busbars within each assembly. This allows adjacent coil assemblies to electrically connect and supply power to each other, eliminating the need for separate power supply wires and maintaining layout flexibility while ensuring reliable power delivery through the integrated resonant circuit.
Solution Approach 2:
Each coil assembly is designed with multi-functionality: it serves as both a power receiving unit and a power supply unit. The resonant capacitor and busbars enable the assembly to store and distribute electrical energy to adjacent assemblies, allowing any coil assembly to function as a local power source and eliminating the need for dedicated power supply connections.
2Power
If power supply wires are arranged to connect power feeding coils with high-frequency power source, then electrical power can be delivered, but space for wire arrangement is required and layout is complicated
Solution Approach 1:
The patent extracts the power supply wire function from the system by integrating power storage and distribution components (resonant capacitor and busbars) directly into each coil assembly. This eliminates the need for separate power supply wires, reducing spatial requirements and simplifying the overall system layout while maintaining electrical power delivery capability.
Solution Approach 2:
The resonant capacitor acts as an intermediary energy storage element within each coil assembly, enabling electrical power to be stored locally and then distributed to adjacent assemblies through busbars. This intermediary mechanism replaces the need for direct wire connections from a central power source, simplifying the power distribution architecture.
