Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single folding region structure is used, then the device is simpler to manufacture, but the device cannot be folded into various shapes
Solution Approach 1:
The display device is divided into multiple folding regions (first folding region, second folding region) and non-folding regions, allowing independent folding operations in each region. This segmentation enables the device to achieve various folding configurations (first mode, second mode, third mode) while maintaining a manageable structural complexity through modular design
Solution Approach 2:
The hinge parts are designed with adjustable characteristics, where the first hinge part connects the first folding support part and second non-folding support part, while the second hinge part connects the second folding support part and third non-folding support part. These dynamic hinge connections allow the device to transition between different folding modes, providing versatility without requiring a completely complex reconfigurable structure
2Adaptability or versatility
If multiple hinge parts are added to enable various folding modes, then folding versatility improves, but the device becomes more complex
Solution Approach 1:
The hinge parts are designed to serve multiple functions: the first hinge part and second hinge part not only connect different support parts but also work together with adjustment parts to control folding in multiple modes. Each hinge part can operate independently or in combination with the other, providing universal functionality that reduces the need for additional specialized components
Solution Approach 2:
Adjustment parts are introduced as intermediary elements between the hinge parts and support parts. The first adjustment part is disposed between the first folding region and first non-folding region, while the second adjustment part is disposed between the second folding region and second non-folding region. These intermediaries simplify the direct connection requirements between hinge parts and support structures, reducing overall system complexity
3Ease of operation
If adjustment parts are disposed between folding and non-folding regions, then folding control improves, but manufacturing complexity increases
Solution Approach 1:
The adjustment parts are designed to be integrated with the existing hinge and support structures, where the first adjustment part connects to the first hinge part and first support parts, and the second adjustment part connects to the second hinge part and second support parts. This self-integrating design allows the adjustment parts to be incorporated into the manufacturing process without requiring separate complex assembly procedures
