Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of moving object
If the screen size is increased and thickness is reduced, then the display device achieves a larger display area and thinner profile, but the structural strength and rigidity deteriorate
Solution Approach 1:
The support structure is divided into multiple extrusion molded members (beams and pillars) arranged in a grid pattern, where each member independently contributes to structural strength. This segmentation allows the large screen to be supported by distributed elements rather than a single heavy frame, maintaining strength while enabling larger screen sizes and thinner profiles.
Solution Approach 2:
The patent employs extrusion molded members made from materials with high strength-to-weight ratio characteristics. These composite or optimized materials provide adequate structural strength while keeping individual member weights low, thus supporting larger screens without compromising rigidity or requiring increased thickness.
2Ease of manufacture
If a single sheet metal housing is used to hold the display panel, then the manufacturing process is simplified, but the weight increases and deformation occurs
Solution Approach 1:
Instead of using a single sheet metal housing, the support structure is segmented into multiple extrusion molded members (beams and pillars) that are separately manufactured and then assembled. This segmentation reduces the weight of individual components while collectively providing adequate support, and the modular nature actually simplifies manufacturing and assembly processes.
Solution Approach 2:
The patent transitions from traditional sheet metal construction to extrusion molded members, changing the manufacturing parameters and material form. This parameter change enables lighter weight components with optimized cross-sectional geometries that provide high structural efficiency, reducing overall device weight while maintaining ease of manufacture through standardized extrusion processes.
3Weight of moving object
If extrusion molded members are used to form a frame structure, then the weight is reduced and manufacturing cost decreases, but the assembly complexity increases
Solution Approach 1:
The frame structure is segmented into standardized extrusion molded members (beams and pillars) that can be manufactured independently using efficient extrusion processes. This segmentation reduces the weight of each component and allows for optimized cross-sectional designs, while the modular nature enables systematic assembly that manages complexity through standardization and repetition of connection methods.
