Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a mechanical implementation is used to solve display movement during folding, then the display stability is improved, but the device complexity increases
Solution Approach 1:
The mobile terminal is divided into two separate cases (first case and second case) that can rotate relative to each other. The display is segmented into a first portion on the first case and a second portion on the second case, allowing independent movement and reducing mechanical complexity while maintaining stability.
Solution Approach 2:
The coupling portion enables dynamic rotation between the first and second cases, allowing the terminal to transition between folded and unfolded states. This dynamic structure replaces complex mechanical implementations with a simpler rotating joint that adapts to different usage states.
2Adaptability or versatility
If the terminal is designed to be folded and unfolded, then the adaptability is improved, but the cases may become spaced apart when unfolded
Solution Approach 1:
Magnetic attraction force replaces mechanical connection mechanisms to maintain case alignment. The magnetic coupling portion attracts the first and second cases together, ensuring they remain closely aligned when unfolded without requiring complex mechanical locking or guiding structures.
3Adaptability or versatility
If the display areas are exposed when unfolded, then the display functionality is improved, but the curvature control becomes difficult
Solution Approach 1:
The display is divided into two portions mounted on separate cases. When the terminal is unfolded, each display portion remains on its respective case, allowing full exposure of display areas while the rigid case structure naturally controls curvature without requiring additional precision mechanisms.
