Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the display remains active to show brief information continuously, then the user can quickly access information, but the battery is consumed unnecessarily
Solution Approach 1:
The display dynamically changes its state based on user interaction. When the device is bent, the display activates to show information; when unbent, it deactivates to save battery. This dynamic state transition resolves the contradiction between quick information access and energy conservation.
Solution Approach 2:
The system uses the bending sensor to automatically detect user intent and activate the display without requiring manual input. The display serves itself by responding to the physical state of the device, eliminating the need for users to press buttons or swipe to wake the screen.
2Ease of operation
If the display activates automatically to show information, then user convenience is improved, but manual input operations become unnecessary
Solution Approach 1:
The bending mechanism serves multiple functions: it acts as both a structural element for device flexibility and a sensing mechanism for user intent detection. This multi-functionality reduces the need for separate sensors and controls, minimizing the increase in device complexity.
Solution Approach 2:
The bending sensor acts as an intermediary between the user's physical action (bending the device) and the display activation. Instead of requiring direct manual input like button presses, the sensor translates the bending motion into a control signal, simplifying the user interface while adding minimal complexity.
3Adaptability or versatility
If the flexible display uses plastic substrate instead of glass, then flexibility and impact resistance are improved, but manufacturing precision is reduced due to low-temperature process requirements
Solution Approach 1:
The manufacturing process parameters are changed from high-temperature (glass substrate) to low-temperature (plastic substrate) processing. This parameter change enables the use of flexible plastic materials while requiring adjusted manufacturing conditions to maintain precision within the new temperature regime.
Solution Approach 2:
The flexible display uses composite material structures with plastic substrates and specialized layers designed to work together at low temperatures. These composite materials provide both the desired flexibility and the manufacturing precision needed for functional performance.

AI summary
A bendable user terminal device provided with a flexible display controls the flexible display to display information on a first area while the user terminal device is maintained in a bent state based on a detected bending state of the user terminal device, and, in response to the user terminal device changing from the bent state to an unbent state, controls the flexible display not to display the information on the first area.
