Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional bending mechanism is used to control the flexible display screen, then the bending control is reliable, but the device complexity increases and the volume becomes large
Solution Approach 1:
The patent uses air bags connected to conduits that can be inflated or deflated to control the bending of the flexible display screen. This pneumatic system replaces complex mechanical bending mechanisms, reducing device complexity and volume while maintaining reliable bending control through simple air pressure regulation.
Solution Approach 2:
The patent controls the bending state by changing the air pressure parameter within the air bags. By adjusting the amount of air in the bags (inflating or deflating), the flexible display screen can be bent to different degrees or returned to its original state, providing simple and reliable bending control without complex mechanisms.
2Reliability
If a conventional bending mechanism is used to control the flexible display screen, then the bending control is reliable, but the device volume becomes large
Solution Approach 1:
The patent employs a pneumatic system with air bags and conduits that occupies minimal space compared to mechanical bending mechanisms. The air bags can be positioned directly behind the flexible display screen, and the conduits connect to a compact air sucking and charging apparatus, significantly reducing the overall device volume while maintaining reliable bending control.
3Volume of moving object
If a compact bending mechanism is used to reduce device volume, then the device volume decreases, but the bending precision may be insufficient
Solution Approach 1:
The pneumatic system provides precise bending control through gradual inflation and deflation of air bags. The air pressure can be precisely regulated to achieve exact bending angles and positions, and the system can be controlled to bend the flexible display screen to specific locations along the conduits, maintaining high bending precision in a compact form factor.
Solution Approach 2:
The patent incorporates a tension sensor that detects the tension state of the flexible display screen and provides feedback to the controller. The controller uses this feedback information to adjust the air pressure in the air bags, enabling precise control of the bending position and angle, and ensuring the screen returns to its original state when needed.
