Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of moving object
If a large-screen display is used, then display area is improved, but device size and portability deteriorate
Solution Approach 1:
The display device employs a flexible display panel that can dynamically change its shape between extended and folded states. The display area can be adjusted from a large unfolded configuration to a compact folded configuration, allowing the device to adapt its size according to usage needs while maintaining a large maximum display area when required.
Solution Approach 2:
The display panel is divided into multiple sections that can be folded relative to each other. This segmentation allows the large display area to be collapsed into a smaller form factor for portability, while still providing the full display area when unfolded for use.
2Adaptability or versatility
If the flexible display shape is changed, then adaptability is improved, but vulnerability to shock damage increases
Solution Approach 1:
The device includes sensors that detect the current shape state of the flexible display and provide feedback to the controller. The controller uses this information to determine whether to activate or deactivate the driving part, preventing shape changes when shock is detected and thus protecting the display from damage while maintaining adaptability when conditions are safe.
Solution Approach 2:
The system proactively prevents shape changes when shock conditions are detected, applying a counter-action to the potential damage by stopping the driving part from actuating. This preliminary protective measure avoids the harmful effect of shock on the flexible display during vulnerable states.
3Reliability
If motion control is added for shock protection, then reliability is improved, but device complexity increases
Solution Approach 1:
The controller serves multiple functions: it controls the driving part for shape changes, processes sensor input signals, determines device state, and activates protection modes. By consolidating these functions into a single controller, the system achieves reliable shock protection without proportionally increasing complexity, as the controller leverages existing computational resources for multiple purposes.
