Engineering Contradiction Analysis
1Reliability
If a trace circuit perimeter is used to detect discontinuities for security, then security against unauthorized tampering is improved, but electrical leakage across dielectric materials increases causing reduced battery life
Solution Approach 1:
The patent changes the electrical parameters of the dielectric material by selecting materials with specific dielectric strength and leakage current characteristics. The system uses dielectric materials with optimized breakdown voltage and resistance properties to minimize leakage current while maintaining the perimeter's security detection function, thereby extending battery life without compromising security monitoring capability.
Solution Approach 2:
The patent employs composite dielectric structures combining multiple materials with complementary properties. By layering different dielectric materials with varying electrical characteristics, the system achieves reduced overall leakage current while maintaining mechanical integrity and security detection functionality, thus resolving the contradiction between security monitoring and energy consumption.

If dielectric materials are used to insulate trace circuit layers, then electrical insulation is improved, but electrical leakage occurs reducing battery life
Solution Approach 1:
The patent optimizes the electrical parameters of dielectric materials by selecting substances with high dielectric strength and low dissipation factor. This parameter optimization reduces the leakage current through the dielectric layers while maintaining adequate insulation between conductive traces, thereby minimizing energy loss without sacrificing electrical insulation performance.
Solution Approach 2:
The patent employs thin dielectric layers that provide sufficient insulation for the application's lifetime. By using sufficiently thin but adequate dielectric materials, the system minimizes the volume and energy storage capacity of the dielectric, thereby reducing leakage current while maintaining necessary electrical insulation for the device's operational life.
