Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a bending unit with fixed facility structure is used, then the manufacturing process is simple, but the facility cannot accommodate changes in flexible circuit board models without modification
Solution Approach 1:
The bending unit employs rotatable adsorption parts that can change orientation dynamically. The first adsorption part and second adsorption part can rotate about a rotation axis, allowing the facility to adapt to different flexible circuit board models by adjusting the angular position of adsorption parts, thereby achieving versatility without requiring structural modifications to the facility itself.
Solution Approach 2:
The bending unit is designed with universal capability to handle multiple flexible circuit board models through its rotatable adsorption parts. The same bending unit can accommodate different circuit board configurations by rotating the adsorption parts to appropriate angles, making the facility multi-functional and adaptable without requiring separate dedicated equipment for each model.
2Ease of operation
If the adsorption part is fixed, then the structure is simple, but the flexible circuit board cannot be bent at different positions
Solution Approach 1:
The adsorption part is designed to rotate about a rotation axis, transforming from a fixed structure to a dynamic one. This rotation capability allows the adsorption part to position itself at different angular orientations, enabling the flexible circuit board to be bent at various positions along its length while maintaining a relatively simple overall structure.
3Adaptability or versatility
If the facility is modified to accommodate new flexible circuit board models, then the adaptability improves, but the manufacturing time and cost increase
Solution Approach 1:
The rotatable adsorption parts enable the facility to adapt to new flexible circuit board models through simple rotational adjustment rather than physical modification. When a new model is introduced, the adsorption parts can be rotated to the appropriate angular position to accommodate the new circuit board configuration, eliminating the need for time-consuming facility modifications and reducing implementation time.
