Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If magnetic resonance technology is used for wireless power transfer, then power transfer capability through solid materials is improved, but device complexity increases due to the need for mechanical adjustment mechanisms
Solution Approach 1:
The transmitter coil is made mechanically adjustable relative to the surface, allowing dynamic positioning to optimize the air gap distance. This enables the system to adapt to different surface thicknesses and material types, maintaining reliable power transfer capability while managing the complexity through controlled mechanical adjustment rather than fixed complex configurations
Solution Approach 2:
The system allows changing of the air gap parameter between the transmitter coil and surface to optimize power transfer. By adjusting this physical parameter based on surface characteristics, the system achieves reliable power transfer through various materials without requiring complex adaptive algorithms or multiple fixed configurations
2Productivity
If the transmitter coil position is fixed, then device complexity is reduced, but power transfer efficiency deteriorates due to inability to optimize for different surface conditions
Solution Approach 1:
The transmitter coil assembly includes mechanical adjustment mechanisms that allow the coil position to be dynamically changed relative to the surface. This enables optimization of the air gap distance for different surface thicknesses and material types, significantly improving power transfer efficiency while maintaining manageable device complexity through straightforward mechanical adjustment
Solution Approach 2:
The system performs preliminary adjustment of the transmitter coil position based on the specific surface conditions before initiating power transfer. This pre-optimization of the air gap distance ensures maximum power transfer efficiency from the start, avoiding the need for complex real-time adjustments during operation
3Adaptability or versatility
If a single wireless power transmitting assembly is used, then device complexity is reduced, but adaptability deteriorates due to inability to serve both legacy and wireless charging devices
Solution Approach 1:
The power station incorporates two distinct wireless power transmitting assemblies: a magnetic resonance transmitter for power transfer through surfaces and an inductive charging pad for direct surface charging. This multi-functional configuration enables the system to serve both legacy devices requiring wired power and modern devices supporting wireless charging, achieving broad adaptability while maintaining reasonable device complexity through modular assembly integration
