Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If separate alignment mechanisms are used for non-contact charging and wireless communication, then alignment precision is improved, but device complexity increases
Solution Approach 1:
The patent combines the charging coil and communication antennas into a single integrated module, where the charging coil serves as the central structural element and the antennas are arranged around it. This merging eliminates the need for separate alignment mechanisms while maintaining alignment precision through the regular interval arrangement of antennas around the coil's central axis.
Solution Approach 2:
The central charging coil structure serves dual purposes: it is the core component for electromagnetic induction charging while also providing the geometric framework for antenna arrangement used in wireless communication. This multi-functionality reduces device complexity by having one component structure serve multiple functions rather than requiring separate structures for charging and communication alignment.
2Productivity
If multiple antennas are arranged around the coil, then wireless communication speed is improved, but interference between charging and communication increases
Solution Approach 1:
The patent positions each antenna at a specific location around the coil's central axis with regular intervals, creating distinct spatial zones for each antenna. This local quality arrangement ensures that each antenna operates in its own optimized spatial region, reducing mutual interference while maintaining high communication speed through the multi-antenna configuration.
Solution Approach 2:
Instead of arranging antennas linearly or in a single plane that might cause interference, the patent distributes them in a circular pattern around the coil's central axis, utilizing the radial dimension. This dimensional arrangement separates the electromagnetic fields of individual antennas in space, reducing interference while enabling high-speed communication through multiple simultaneous transmission paths.
3Reliability
If precise alignment is required between charging coils and communication antennas, then communication reliability is improved, but ease of operation deteriorates
Solution Approach 1:
By integrating the charging coil and communication antennas into a single module with the antennas arranged around the coil, the patent ensures that alignment for charging automatically provides the correct geometric relationship for communication. This merging means that a single alignment action achieves both charging and communication reliability simultaneously, greatly improving ease of operation.
Solution Approach 2:
The regular interval arrangement of antennas around the coil's central axis is pre-configured during manufacturing, establishing the optimal geometric relationship before use. This preliminary arrangement ensures that when the device is placed for charging, the alignment is automatically correct for both charging and communication functions, eliminating the need for user adjustment and improving ease of operation while maintaining reliability.
