Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If resonant LC circuits are implemented in each electronic circuit for wireless signal transmission, then signal transmission capability is improved, but area occupation increases excessively
Solution Approach 1:
The resonant LC circuit is divided into two separate parts: a capacitor integrated in the first electronic circuit and an inductor integrated in the second electronic circuit. This segmentation allows each circuit to contribute one component, reducing the area occupation in each individual circuit while maintaining the wireless signal transmission capability through the distributed resonant structure.
2Reliability
If full resonant LC circuits are implemented in each electronic circuit, then wireless signal and power transmission is enabled, but the number of components and production costs increase
Solution Approach 1:
The complete resonant LC circuit is segmented across two electronic circuits, with each circuit implementing only one component (capacitor or inductor). This reduces the component count per circuit from two to one, simplifying the device structure and reducing production costs while maintaining wireless signal and power transmission capability through the coupled resonant system.
Solution Approach 2:
The distributed resonant LC circuit structure enables a single component in each circuit to serve dual purposes: the capacitor and inductor together enable both signal transmission and power supply functionality. This multi-functionality is achieved through the resonant coupling between the two circuits, eliminating the need for separate transmission and power components.
3Reliability
If electrical connections are used for coupling electronic circuits, then connection reliability is improved, but parasitic effects limit maximum frequency and cause power dissipation
Solution Approach 1:
The physical electrical connection (mechanical/system-based coupling) is replaced with a field-based coupling mechanism using resonant LC circuits. The capacitor and inductor create an electromagnetic resonant field that enables wireless signal and power transmission, eliminating the parasitic effects associated with physical interconnection tracks while maintaining connection reliability.
