Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a flexible display panel is used to enable bending, then adaptability and versatility are improved, but precise control over the bending angle is lost
Solution Approach 1:
The bending control portion is divided into multiple blocks (first block, second blocks, third blocks) that can be independently rotated relative to each other. Each block can be controlled to rotate by a predetermined angle, enabling precise control of the overall bending angle of the flexible display panel through coordinated rotation of individual blocks.
2Measurement precision
If blocks are rotated to control bending angle, then bending angle precision is improved, but device complexity increases
Solution Approach 1:
Multiple functional components (blocks, pulley units, wire fixing units, driving units) are merged into an integrated bending control portion that works as a coordinated system. The blocks are connected through pulley units and wires to driving units, forming a unified structure that controls bending through the combined action of all components rather than separate independent mechanisms.
Solution Approach 2:
Pulley units and wires act as intermediary mechanisms between the driving units and the blocks. The driving units rotate the pulley units, which in turn control the rotation of blocks through the wires. This intermediary mechanism enables precise control of block rotation angles while isolating the complexity of the control system from the display panel itself.
3Adaptability or versatility
If side surfaces of blocks are spaced apart to allow rotation, then bending flexibility is improved, but structural stability deteriorates
Solution Approach 1:
The spacing between side surfaces of adjacent blocks is designed to be dynamic rather than fixed. The blocks can rotate relative to each other by a predetermined angle, allowing the spacing to change during operation. This dynamic adjustment enables the structure to maintain stability in its extended state while achieving flexibility during bending through controlled rotation of individual blocks.
