Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If single-coil or three-coil charging mode is used, then device structure is simplified, but multi-device simultaneous charging and multi-protocol support are not achieved
Solution Approach 1:
The charging system is divided into multiple independent coil units (first coil unit and second coil unit), each capable of independently charging a device. This segmentation allows simultaneous multi-device charging while keeping each coil unit's structure relatively simple.
Solution Approach 2:
Each coil unit is designed to support multiple wireless charging protocols (QI and PMA standards), making the coils universal and adaptable to different device types. This multi-functionality enables the system to charge various devices simultaneously without requiring separate dedicated coils for each protocol.
2Productivity
If device alignment is required for charging, then charging efficiency is improved, but ease of operation deteriorates
Solution Approach 1:
The patent introduces spatial dimensionality by arranging multiple coil units in different spatial positions and orientations. This three-dimensional coil array configuration creates overlapping magnetic field zones that can accommodate devices at various positions and angles, eliminating the need for precise alignment while maintaining charging efficiency through intelligent coil selection and combination.
3Adaptability or versatility
If multiple coils are used for multi-device charging, then charging versatility is improved, but device complexity increases
Solution Approach 1:
The control unit continuously monitors the charging status, protocol requirements, and device positions of all charged devices. Based on this real-time feedback, the control unit dynamically adjusts which coil units are activated and how they are configured, optimizing the charging process while managing system complexity through intelligent resource allocation.
Solution Approach 2:
The system dynamically configures the operational state of each coil unit based on real-time charging demands. The control unit can independently control each coil unit's activation, power level, and protocol, allowing the system to adapt its complexity level to match the actual number and type of devices being charged, rather than maintaining fixed high complexity regardless of usage.
