Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If conventional methods are used to maintain curved shape, then curved shape can be achieved, but material usage increases and manufacturing cost increases
Solution Approach 1:
The bottom chassis is divided into multiple reinforcement structures distributed across the surface. These segmented reinforcement elements work together to maintain the curved shape without requiring excessive material throughout the entire chassis, thereby resolving the contradiction between achieving curved shape and reducing material usage.
Solution Approach 2:
Reinforcement structures are strategically placed in specific locations where structural support is most needed to maintain the curved shape. This localized approach ensures the curved shape is maintained while minimizing overall material usage, as material is concentrated only where required rather than distributed uniformly.
2Shape
If conventional methods are used to maintain curved shape, then curved shape can be achieved, but manufacturing cost increases
Solution Approach 1:
The bottom chassis employs segmented reinforcement structures that can be manufactured and assembled more efficiently than conventional continuous reinforcement methods. This segmentation reduces manufacturing complexity and cost while maintaining the required curved shape.
Solution Approach 2:
By concentrating reinforcement only in critical areas rather than throughout the entire chassis, the manufacturing process is simplified and material costs are reduced, making curved display devices more cost-effective to produce.
3Stability of the object's composition
If reinforcement structure is formed by roll-forming process, then shape retention is enhanced, but process complexity increases
Solution Approach 1:
The reinforcement structures are pre-formed using the roll-forming process before being integrated into the bottom chassis. This preliminary formation ensures proper shape retention characteristics are built into the reinforcement elements themselves, simplifying the overall assembly process while maintaining shape stability.
