Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional wireless charging configuration is used, then the base station can provide wireless charging service, but the charging efficiency is low and charging time is prolonged
Solution Approach 1:
The terminal performs preliminary measurements of downlink signal quality and determines its expected wireless charging configuration before sending the charging request. This preliminary action allows the network device to make faster configuration decisions, improving charging efficiency and reducing charging time.
Solution Approach 2:
The terminal provides feedback information including downlink signal quality measurements and expected configuration parameters to the network device. This feedback mechanism enables the network device to optimize the wireless charging configuration based on actual terminal conditions, thereby improving charging efficiency.
2Reliability
If the terminal sends detailed auxiliary information, then the network device can determine optimal charging configuration, but the signaling overhead increases
Solution Approach 1:
The patent extracts only the most essential auxiliary information needed for configuration determination, specifically downlink signal quality measurements and expected configuration parameters. By taking out only the critical information rather than transmitting all possible terminal parameters, the signaling overhead is reduced while maintaining configuration accuracy.
Solution Approach 2:
The terminal changes the parameter representation by providing measured signal quality values and derived expected configuration parameters rather than raw terminal capabilities. This parameter transformation reduces the amount of information needed while maintaining the ability to determine accurate charging configuration.
