Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional wireless charging systems use coil pairing for energy transmission, then energy transfer can be achieved, but precise placement of mobile devices on charging pads is required
Solution Approach 1:
The patent segments the traditional single coil structure into multiple independent feed layers, each capable of generating electromagnetic fields. This segmentation allows the system to maintain reliable energy transfer while reducing sensitivity to placement precision, as multiple feed layers can compensate for misalignment issues
Solution Approach 2:
The patent implements a nested structure where multiple feed layers are stacked vertically, with each layer containing signal feed-in parts and antenna parts. This nested arrangement of feed layers creates overlapping electromagnetic fields that expand the effective charging area, allowing wireless charging without precise placement
2Use of energy by moving object
If conventional wireless charging systems require accurate coil pairing, then efficient energy transmission is achieved, but charging flexibility is limited
Solution Approach 1:
The patent creates a universal charging system where multiple feed layers serve multiple functions: they can charge devices at various positions, support different device types, and maintain efficiency across a broader area. This multi-functionality achieves both energy transmission efficiency and charging flexibility simultaneously
3Reliability
If conventional wireless charging systems use traditional antenna structures, then coil pairing is required, but design flexibility is reduced
Solution Approach 1:
The patent merges the signal feed-in function and antenna function into an integrated feed layer structure. The feed layer contains both signal feed-in parts and antenna parts that work together as a unified system, eliminating the need for separate coil pairing mechanisms while maintaining reliable charging connections
