Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a wireless charging base charges multiple electronic devices simultaneously using the same wireless charging standard, then the charging process is simplified, but electromagnetic interference increases and charging stability deteriorates
Solution Approach 1:
The patent dynamically changes the wireless charging standard parameter (frequency band) based on the number of devices being charged. When multiple devices are detected, the system switches from using a single wireless charging standard to using multiple different standards simultaneously, thereby reducing electromagnetic interference while maintaining operational simplicity through automated detection and assignment
2Adaptability or versatility
If a wireless charging base supports multiple wireless charging standards, then adaptability to different devices improves, but device complexity and management difficulty increase
Solution Approach 1:
The wireless charging base automatically detects the number of electronic devices placed on it and autonomously determines the appropriate wireless charging standard for each device without user intervention. The system self-manages the allocation of different standards (first, second, third standards) based on device count, thereby maintaining high adaptability while reducing the perceived complexity for users
3Device complexity
If the same wireless charging standard is used for all devices, then system complexity is reduced, but electromagnetic interference increases and charging efficiency decreases
Solution Approach 1:
The system dynamically adjusts the wireless charging standard parameter based on the number of devices being charged simultaneously. When one device is present, a single standard is used; when multiple devices are present, the system switches to using multiple different standards with different frequency bands, thereby reducing electromagnetic interference and maintaining high charging efficiency while keeping the system complexity manageable through automated control
