Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate power and communications modules are used to transmit control and power signals, then reliable wireless charging and control functions are achieved, but hardware structure becomes complex and costs increase
Solution Approach 1:
The patent combines separate power and communications modules into a single integrated module. The composite signal carries both power transmission and control communication functions through one unified hardware structure, eliminating the need for separate transmit antennas and reducing system complexity while maintaining reliable wireless charging and control capabilities
Solution Approach 2:
The integrated module serves multiple functions simultaneously - it transmits both power signals and control signals through a single composite signal. The single transmit antenna and module perform dual roles of power delivery and communication, making the system more versatile and reducing component count
2Reliability
If separate power and communications modules are used, then independent signal transmission is ensured, but the number of antennas and switches increases leading to higher costs
Solution Approach 1:
The patent merges multiple antennas into a single transmit antenna and combines multiple switches into one within the integrated module. This reduction in component quantity directly lowers manufacturing costs while the composite signal design ensures that power and control signals remain independently controllable through signal processing rather than physical separation
