Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If wireless power supplying is used, then placement flexibility is improved, but energy efficiency deteriorates
Solution Approach 1:
The system dynamically switches between wireless and wired power receiving modes based on real-time detection of wired connection status. The switching module changes the power receiving mode from wireless to wired when a power line connection is detected, and vice versa, optimizing energy efficiency while maintaining placement flexibility.
Solution Approach 2:
The detecting module continuously monitors whether a wired connection is established, and this detection result feeds back to the switching module to automatically adjust the power receiving mode. This feedback mechanism ensures the system operates in the most energy-efficient mode available at any given time.
2Adaptability or versatility
If both wired and wireless power receiving modules are included, then adaptability is improved, but device complexity increases
Solution Approach 1:
The patent combines both wired and wireless power receiving modules within a single electronic device, along with a detecting module and a switching module. These modules work together as an integrated system to provide dual power receiving capabilities, achieving adaptability while managing complexity through functional integration.
Solution Approach 2:
The power receiving system is designed to perform multiple functions: it can receive power through both wired and wireless connections, automatically detect the available connection type, and switch between modes. This multi-functionality allows a single system to adapt to different power supply scenarios without requiring separate independent systems.
