Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If the electronic device performs wireless power transmission to a remote control device, then power transmission function is improved, but wireless communication with the access point may be interrupted
Solution Approach 1:
The antenna elements are segmented into multiple independent units that can be independently controlled and allocated. The processor can selectively assign different antenna elements to wireless communication or wireless power transmission functions, allowing simultaneous operation of both functions without mutual interference.
Solution Approach 2:
The system dynamically allocates antenna elements based on operational requirements. When wireless power transmission is needed, the processor can switch specific antenna elements to support power transmission while maintaining other antenna elements for communication, enabling flexible and adaptive resource management.
2Use of energy by moving object
If the electronic device operates in low-power mode, then energy consumption is reduced, but the ability to perform wireless power transmission is limited
Solution Approach 1:
The electronic device applies local quality by enabling wireless power transmission function selectively in specific low-power modes rather than disabling it entirely. The processor determines whether to enable the wireless power transmission function based on the current low-power mode operation, allowing power transmission capability to be preserved in certain low-power states while maintaining overall energy efficiency.
3Adaptability or versatility
If multiple antenna elements are used for simultaneous wireless communication and power transmission, then functional versatility is improved, but device complexity increases
Solution Approach 1:
The antenna elements are designed with multi-functionality, capable of supporting both wireless communication and wireless power transmission operations. This universal design allows the same hardware components to serve multiple purposes, reducing the need for separate dedicated antennas for each function and thereby managing complexity while maintaining versatility.
