Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If wireless charging method is used, then convenience is improved, but charging efficiency becomes unstable due to variable coil positioning
Solution Approach 1:
The charging system performs self-alignment automatically through magnetic interaction between the charging module and wearable device. The magnets and magnetic electrodes attract each other to achieve precise positioning without user intervention, ensuring stable electrode contact and consistent charging efficiency while maintaining wireless charging convenience.
Solution Approach 2:
The patent replaces manual mechanical alignment with magnetic field-based self-alignment. Magnetic forces between the charging module and wearable device automatically position the electrodes correctly, eliminating the need for precise manual placement and ensuring reliable charging efficiency.
2Reliability
If wired charging method is used, then charging efficiency is improved, but ease of operation deteriorates due to need for direct coupling
Solution Approach 1:
The patent introduces magnetic electrodes as an intermediary between wireless and wired charging. These electrodes enable direct electrical contact for efficient charging while the magnetic alignment mechanism automates the coupling process, eliminating the manual effort required for traditional wired charging.
3Reliability
If self-alignment structure is added, then charging stability is improved, but device complexity increases
Solution Approach 1:
The patent merges the alignment function and charging function into a single integrated system. Magnets for alignment and magnetic electrodes for charging are combined in one module, achieving stable charging without requiring separate alignment mechanisms and reducing overall system complexity.
Solution Approach 2:
The magnetic components serve dual purposes: magnets provide both structural support and alignment force, while magnetic electrodes simultaneously enable magnetic attraction for positioning and electrical conduction for charging. This multi-functionality reduces the number of separate components needed.
