Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a curved pouch-shaped battery is used to match electronic device shapes, then adaptability to device designs is improved, but dimensional stability deteriorates due to external impact
Solution Approach 1:
The patent introduces a tray as an intermediary component between the curved battery and the electronic device. The tray has a curved receiving part that matches the battery's curvature, providing external support and protection. This mediator structure allows the battery to maintain its curved shape for device adaptability while the tray protects it from external impacts that would cause dimensional instability.
2Adaptability or versatility
If a curved battery structure is implemented, then design flexibility is improved, but manufacturing precision deteriorates due to curvature changes
Solution Approach 1:
The tray is designed with a pre-formed curved receiving part that matches the desired battery curvature. By preparing this supporting structure in advance, the tray provides a predetermined geometric constraint that guides and maintains the battery's curvature during manufacturing and assembly, ensuring consistent curvature precision across production batches.
3Ease of operation
If a curved battery is mounted without additional support, then device integration simplicity is improved, but reliability deteriorates due to curvature changes from impact
Solution Approach 1:
The tray combines multiple functions into a single component: it serves as both the mounting structure and the protective support for the curved battery. The curved receiving part is integrated into the tray body, providing both structural support for easy mounting and protective enclosure for maintaining curvature stability under external impact.
