Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the wireless IC chip is arranged on the antenna pattern using an Au bump, then electrical connection is achieved, but positional deviation changes resonant frequency characteristics
Solution Approach 1:
The patent replaces the mechanical Au bump connection system with an electromagnetic field coupling system. The power supply circuit board generates electromagnetic fields that couple with the antenna pattern, eliminating the need for precise mechanical positioning and Au bump connections. This substitution resolves the contradiction by maintaining reliable electrical connection through field coupling while being insensitive to positional deviations.
Solution Approach 2:
The patent introduces electromagnetic fields as an intermediary between the power supply circuit and the antenna pattern. Instead of direct mechanical connection, the power supply circuit board generates electromagnetic fields that mediate the energy transfer to the antenna, allowing flexible positioning while maintaining reliable coupling.
2Adaptability or versatility
If the antenna pattern is rolled or sandwiched between dielectric bodies, then product integration is achieved, but resonant frequency characteristics are changed
Solution Approach 1:
The patent replaces the mechanical antenna structure that is sensitive to physical deformation with an electromagnetic field-based power supply system. The power supply circuit board generates electromagnetic fields that can penetrate dielectric bodies and maintain coupling with the antenna pattern regardless of whether the antenna is rolled or sandwiched, thus maintaining frequency characteristics while achieving product integration.
Solution Approach 2:
The patent changes the operating parameters from mechanical positioning and physical antenna configuration to electromagnetic field frequency and intensity control. By controlling the electromagnetic field parameters generated by the power supply circuit board, the system maintains stable resonant frequency characteristics even when the physical antenna configuration changes due to rolling or sandwiching between dielectric bodies.
3Adaptability or versatility
If the radiation plate shape, size, or arrangement is changed, then product design flexibility is improved, but frequency characteristics become unstable
Solution Approach 1:
The patent replaces the mechanical radiation plate system with an electromagnetic field-based power supply circuit board. The power supply circuit generates electromagnetic fields that couple with the antenna pattern, and this field-based approach is insensitive to the shape, size, or arrangement of any physical plate structures, thereby maintaining frequency stability while allowing design flexibility.
Solution Approach 2:
The power supply circuit board serves multiple functions: it provides power supply, generates electromagnetic fields for wireless communication, and maintains frequency stability regardless of product configuration. This universal approach allows the same circuit board design to be used across products with different radiation plate configurations, achieving both design flexibility and frequency stability.
