Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If laser or chemical treatment is used to separate display cells, then separation can be achieved, but the procedure becomes complicated and manufacturing cost increases
Solution Approach 1:
The patent replaces complex laser or chemical treatment systems with a simple mechanical rotation system. The display sheet is adhered to a rotation stage, and by rotating the stage, mechanical stress is applied to separate the display cells along pre-formed cracks, eliminating the need for complicated laser or chemical procedures.
Solution Approach 2:
The patent changes the physical state and mechanical properties of the display sheet through controlled rotation. By rotating the loading stage at specific speeds and angles, the mechanical stress parameters are adjusted to propagate cracks and separate cells efficiently, replacing complex thermal or chemical parameters with simple mechanical rotation parameters.
2Ease of operation
If manual separation is used, then operation is simple, but quality varies due to human error and production output varies according to worker expertise
Solution Approach 1:
The system uses an automated rotation mechanism that self-regulates the separation process. The rotation stage automatically applies consistent mechanical stress to separate cells, eliminating dependence on worker expertise and ensuring uniform quality across all separations while maintaining operational simplicity.
Solution Approach 2:
The patent introduces dynamic rotation motion to replace static manual pressing. By controlling the rotation speed and angle of the loading stage, the system dynamically adjusts mechanical stress distribution, ensuring consistent separation quality without requiring skilled operators to manually control pressure and angle for each cell.
3Ease of manufacture
If manual separation is used, then equipment cost is low, but production output varies significantly according to worker expertise
Solution Approach 1:
The patent segments the display sheet into multiple cells on a single loading stage, allowing simultaneous or sequential separation of multiple cells through one rotation operation. This increases production output significantly compared to manual one-by-one separation, while the equipment remains relatively simple and cost-effective.
Solution Approach 2:
The rotation mechanism enables continuous separation action across multiple cells in a single operational cycle. Unlike manual separation where each cell requires individual attention, the rotating stage continuously applies stress to propagate cracks across all cells, maintaining high productivity with simple, continuous motion rather than repeated manual operations.
