Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If overlapping cores are used to extend chargeable range, then chargeable range is improved, but magnetic field interference occurs and simultaneous charging of multiple devices is prevented
Solution Approach 1:
The patent divides the charging system into multiple independent transmitting coils (first transmitting coil and second transmitting coil) with separate control, allowing each coil to charge different devices independently without magnetic field interference, thus enabling simultaneous charging of multiple devices while extending chargeable range
Solution Approach 2:
The patent implements a tilt function that allows the terminal holder to dynamically adjust its angle relative to the charging surface, enabling the charging device to adapt to different device positions and orientations, thereby extending the effective chargeable range without causing magnetic field interference
2Productivity
If precise positioning is required for effective charging, then charging efficiency is improved, but ease of operation deteriorates due to narrow chargeable physical range
Solution Approach 1:
The tilt function allows the terminal holder to dynamically adjust its angle, creating a larger effective charging area that accommodates various device positions and orientations, thus improving ease of operation while maintaining charging efficiency through multiple transmitting coils
Solution Approach 2:
The charging device is designed with multiple transmitting coils that can simultaneously charge multiple devices of different types and sizes, making the device universal and easy to use for various user terminals without requiring precise positioning
3Reliability
If one transmitting device supplies power to only one user terminal, then magnetic field interference is avoided, but productivity deteriorates due to inability to charge multiple devices simultaneously
Solution Approach 1:
The patent segments the transmitting function into multiple independent transmitting coils, each capable of independently supplying power to a user terminal, allowing multiple devices to be charged simultaneously without magnetic field interference between overlapping cores
Solution Approach 2:
The patent combines multiple transmitting coils and plate cores into a single integrated charging device, enabling the device to simultaneously charge multiple user terminals while maintaining charging stability through independent control of each coil
