Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a flexible display panel is used in wearable devices, then the display area can be adjusted to enhance product experience, but the device becomes difficult to unfold or fold manually, adversely affecting user experience
Solution Approach 1:
The elastic connector is configured to automatically urge the movable portion and fixed portion to approach each other, enabling the display apparatus to fold itself without manual intervention. The elastic connector provides restoring force that drives the folding action, making the system self-serving in the folding operation.
Solution Approach 2:
The patent replaces manual mechanical folding operations with an elastic connector-based automatic folding mechanism. The elastic connector converts stored elastic potential energy into mechanical work that drives the folding motion, substituting human manual operation with an automated mechanical system.
2Ease of operation
If automatic folding is implemented using an elastic connector, then ease of operation is improved, but the device complexity increases due to additional components
Solution Approach 1:
The patent combines the elastic connector with limiting structures and hovering assemblies into an integrated connecting assembly. These components work together as a unified system to achieve automatic folding with stable positioning, merging multiple functions into a single assembly to manage complexity.
Solution Approach 2:
The connecting assembly is divided into functional modules: the elastic connector for providing restoring force, limiting structures for controlling movement ranges, and hovering assemblies for maintaining states. This segmentation allows each component to perform its specific function independently while contributing to the overall automatic folding mechanism.
3Reliability
If limiting structures are added to control movement direction, then positioning stability is improved, but the device complexity increases
Solution Approach 1:
The limiting structures act as intermediary elements between the elastic connector and the movable portion, controlling the movement direction and range. These limiting structures mediate the interaction between components, ensuring the movable portion moves only within the intended range while maintaining positioning stability.
