Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If a single electrode assembly is used for wireless power transfer, then the system is simple in structure, but the power transfer capacity is limited and insufficient for high power demand devices
Solution Approach 1:
The electrode assembly is segmented into multiple conductive plates arranged in series, where each plate contributes to the overall power transfer capacity. This segmentation allows the system to achieve higher power capacity while maintaining a manageable structural complexity through modular design.
Solution Approach 2:
Multiple conductive plates are merged into a single integrated electrode assembly structure, combining their individual power transfer capabilities to achieve higher overall power capacity. The series arrangement of plates merges their electrical fields to create a unified high-power transfer system.
2Loss of energy
If resonant electric fields are used for wireless power transfer, then the efficiency is improved, but the frequency stability and amplitude consistency become challenging to maintain
Solution Approach 1:
The electrode assembly incorporates adjustable spacing between conductive plates, allowing dynamic optimization of the resonant frequency and field coupling. This dynamic adjustment capability enables the system to maintain frequency stability and amplitude consistency while maximizing power transfer efficiency under varying operating conditions.
Solution Approach 2:
The system utilizes controlled changes in the spacing parameter between conductive plates to optimize resonant frequency and field coupling strength. By adjusting this geometric parameter, the system maintains stable resonant operation and consistent amplitude across different power transfer scenarios.
3Power
If the electrode assembly uses multiple conductive plates with spacing, then the power transfer capacity increases, but the physical footprint and device size increase
Solution Approach 1:
The multiple conductive plates are arranged in a stacked configuration along the vertical dimension rather than spreading out horizontally. This dimensional reorganization allows the system to increase power transfer capacity through additional plates while minimizing the horizontal footprint, effectively transitioning from a two-dimensional to a three-dimensional arrangement.
