Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the display is made flexible and transformable between extended and reduced states, then the adaptability and functionality of the device are improved, but the structural integrity and stability of the display are worsened
Solution Approach 1:
The support structure is divided into multiple support bars (first support bars and second support bars) that are distributed across different areas of the display. This segmentation allows each support bar to independently maintain structural integrity in specific regions while enabling overall display flexibility and transformation between extended and reduced states.
Solution Approach 2:
The lattice plate structure with its grid-like pattern of interconnected bars creates a nested framework that provides structural support throughout the display area. This nested structure maintains display stability during transformation while allowing the display to remain flexible and transformable between different states.
2Area of moving object
If the display area is extended by moving housings, then the visibility and functionality are improved, but the structural complexity and manufacturing difficulty are worsened
Solution Approach 1:
Multiple support bars are connected to the lattice plate using the same welding technique, merging the manufacturing process across different components. This approach simplifies production by standardizing the connection method while enabling the assembly of multiple support elements into a cohesive structure that facilitates display area extension.
Solution Approach 2:
The lattice plate serves multiple functions: it provides structural support, facilitates welding of support bars, and enables display transformation. This multi-functionality reduces the need for separate components and simplifies the overall manufacturing process while maintaining the ability to extend the display area.
3Strength
If welding is used to connect support bars to the lattice plate, then the connection strength is improved, but the manufacturing precision requirements are worsened
Solution Approach 1:
Welding is applied selectively at specific locations where support bars intersect with the lattice plate, rather than across the entire structure. This localized welding approach concentrates the required precision at critical connection points while maintaining overall structural strength, reducing the total manufacturing precision burden.
Solution Approach 2:
The structure combines the lattice plate material with support bar materials through welding, creating a composite assembly that leverages the strengths of each component. This composite approach allows the use of welding to achieve strong connections while the design of the lattice plate and support bars accommodates reasonable manufacturing tolerances.
