Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If conventional insulating materials such as polyolefin are used in non-contact power supply components, then insulation performance is ensured, but transmission loss increases due to high dielectric loss and permittivity
Solution Approach 1:
The patent changes the dielectric parameters by selecting specific resin materials with inherently low relative permittivity and low dielectric loss tangent values. This material parameter selection directly reduces transmission loss while maintaining the necessary insulation performance for non-contact power supply components.
Solution Approach 2:
The patent employs composite resin compositions combining multiple polymer materials to achieve optimal balance between dielectric properties and mechanical performance. The composite structure allows synergistic effects that reduce overall dielectric loss while maintaining structural integrity and insulation reliability.
2Weight of moving object
If the non-contact power supply component is made thinner and lighter, then ease of installation and portability is improved, but transmission loss reduction becomes more difficult due to reduced material volume for insulation
Solution Approach 1:
The patent achieves lightweight design by selecting resin materials with inherently low dielectric loss properties, allowing thinner component designs that would otherwise suffer from insufficient insulation. The superior material parameters compensate for reduced thickness, maintaining low transmission loss in lightweight configurations.
3Reliability
If high dielectric loss materials are used, then insulation strength is improved, but power supply efficiency decreases due to increased energy loss
Solution Approach 1:
The patent identifies and selects resin materials with specific dielectric parameter ranges that simultaneously provide adequate insulation strength and minimal energy loss. By optimizing the balance between relative permittivity and dielectric loss tangent, the invention achieves both reliable insulation and high power supply efficiency.
