Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If wireless charging is provided without user control, then the charging process is simple to implement, but user satisfaction and control capability are reduced
Solution Approach 1:
The portable electronic device acts as an intermediary between the wireless power supply device and external devices. It receives charging requests from external devices, manages authentication, and coordinates with the power supply device, thereby providing user control without requiring the power supply device itself to be complex.
Solution Approach 2:
The charging management function is segmented into multiple components: authentication module, request management module, and coordination module. This segmentation allows user control capabilities to be distributed across different functional blocks, improving ease of operation while managing complexity through modular design.
2Adaptability or versatility
If multiple external devices are charged simultaneously without management, then charging versatility is improved, but charging efficiency and power distribution are reduced
Solution Approach 1:
The system dynamically manages charging parameters for multiple devices based on real-time conditions. The portable electronic device adjusts power distribution, charging rates, and resource allocation dynamically, allowing versatile multi-device charging while maintaining high charging efficiency through adaptive control.
Solution Approach 2:
Charging parameters such as power output, frequency, and voltage are changed dynamically based on device requirements and power availability. This allows the system to accommodate multiple device types with different charging needs while optimizing overall charging efficiency through parameter adjustment.
3Reliability
If authentication is not performed, then the charging process is faster and simpler, but security and power waste control are reduced
Solution Approach 1:
Authentication is performed preliminarily before the actual charging process begins. The portable electronic device verifies device identity and charging eligibility in advance, ensuring security and preventing power waste. This preliminary authentication minimizes its impact on overall charging time by completing verification before power transfer starts.
