Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the charged device determines the charging position according to pre-drawn indication for diversified devices, then the charging position can be indicated, but the adaptability is insufficient due to device diversity
Solution Approach 1:
The charged device autonomously detects charging intensity at different positions and determines the optimum charging position itself, without relying on pre-drawn indication diagrams. This self-service approach enables the device to adapt to its own characteristics and the wireless charging device, resolving the adaptability issue while maintaining simplicity.
Solution Approach 2:
The system implements feedback by detecting charging intensity at multiple positions, comparing the detected intensities, and using this feedback information to determine the optimum charging position. This feedback mechanism enables adaptive positioning that works across different device types without complex pre-defined indications.
2Productivity
If the user places the charged device at different positions on the wireless charging device, then different charging efficiencies are achieved, but the user cannot identify the optimum position without indication
Solution Approach 1:
The charged device detects charging intensity at the current position and provides feedback to the user through display or notification. This feedback enables the user to identify the optimum charging position based on actual charging intensity rather than relying on visual indications or trial-and-error placement.
Solution Approach 2:
The patent replaces mechanical/visual indication systems (pre-drawn diagrams) with an electronic detection and feedback system. The charged device electronically detects charging intensity and communicates this information to the user, eliminating the need for physical indication markings on the charging surface.
3Ease of operation
If wireless charging intensity is displayed on the display screen, then the user can select the optimum charging position, but additional detection and processing functions are required
Solution Approach 1:
The charged device utilizes its existing display screen and processing capabilities to show charging intensity information, rather than adding dedicated indication hardware. This multi-functional approach provides user convenience while minimizing additional system complexity by repurposing existing components.
Solution Approach 2:
The charged device performs self-detection of charging intensity and self-display of the information on its own display screen. This self-service capability provides user convenience without requiring external indication systems or additional complex infrastructure.
