Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If wireless power supply is implemented without communication between power supply apparatus and electronic apparatus, then power supply can be provided simply, but the power supply apparatus cannot correctly detect the function and status of the electronic apparatus, leading to inadequate power control
Solution Approach 1:
The patent implements a communication unit in the power supply apparatus that enables bidirectional communication with the electronic apparatus. This feedback mechanism allows the power supply apparatus to receive status information, device type data, and power reception capability information from the electronic apparatus, and to send control commands. Based on the received feedback information, the power supply apparatus can dynamically adjust power supply parameters, ensuring reliable power control while maintaining system simplicity through automated decision-making algorithms.
2Measurement precision
If communication unit is added to detect device status and function, then power control accuracy is improved, but device complexity increases
Solution Approach 1:
The communication unit is designed with multi-functionality to minimize overall system complexity. It simultaneously performs multiple tasks: device authentication, status detection, power capability negotiation, and control command transmission. By consolidating these functions into a single communication module rather than separate dedicated components, the patent achieves high measurement precision for device status detection while avoiding proportional increases in apparatus structure complexity.
Solution Approach 2:
The patent merges the communication functions with the existing power supply control system. The communication unit is integrated into the power supply apparatus structure, sharing hardware resources and control logic with the power supply unit. This merging approach allows the system to achieve accurate device status detection through communication without requiring completely separate detection hardware, thereby improving measurement precision while limiting the increase in device complexity.
