Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If inductive coupling is used for wireless energy transfer, then energy transfer efficiency is improved, but data exchange bandwidth and performance deteriorate
Solution Approach 1:
The patent divides the coupling mechanism into two separate channels: inductive coupling for energy transfer and capacitive coupling for data exchange. This segmentation allows each channel to be optimized independently, resolving the contradiction by enabling high energy transfer efficiency through inductive coupling while achieving high data exchange bandwidth through capacitive coupling without interference between the two functions.
Solution Approach 2:
The patent makes the system multi-functional by enabling the primary and secondary circuits to perform both energy transfer and data exchange simultaneously through two distinct coupling mechanisms. The inductive channel handles power transmission while the capacitive channel handles data communication, allowing the system to universally support both functions with high performance.
2Device complexity
If inductive coupling is used for both energy transfer and data exchange, then device complexity is reduced, but data transfer rates deteriorate
Solution Approach 1:
The patent segments the coupling functions into distinct inductive and capacitive channels, allowing data transfer to occur through the capacitive channel at high speeds while energy transfer occurs through the inductive channel. This segmentation resolves the contradiction by enabling high data transfer rates without requiring a completely separate dedicated data channel, thus avoiding excessive device complexity.
Solution Approach 2:
The patent changes the coupling parameter from purely inductive to a combination of inductive and capacitive coupling. By introducing capacitive coupling for data exchange while maintaining inductive coupling for energy transfer, the system achieves high data transfer rates without significantly increasing device complexity, as both coupling mechanisms can be implemented within the same circuit architecture.
3Loss of energy
If high inductive values are used for energy transfer, then energy transfer efficiency is improved, but data exchange performance deteriorates
Solution Approach 1:
The patent segments the coupling functions so that high inductive values can be used for energy transfer without affecting data exchange performance. The inductive channel with high inductance values optimizes energy transfer efficiency, while the separate capacitive channel handles data exchange, preventing information loss and maintaining high data exchange performance independent of the inductive coupling parameters.
Solution Approach 2:
The patent introduces capacitive coupling as an intermediary mechanism for data exchange that operates independently of the inductive coupling used for energy transfer. This intermediary capacitive channel mediates the data exchange function, allowing high inductive values to be used for energy transfer without degrading data exchange performance, as the two functions are decoupled through this intermediary mechanism.
