Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the lateral wall and blocking portion are formed as separate components, then assembly flexibility is improved, but the number of components increases and assembly complexity increases
Solution Approach 1:
The lateral wall and blocking portion are merged into a single integrated component formed from one metal sheet. This reduces the total number of components while maintaining the functional benefits of both elements, directly resolving the contradiction between assembly flexibility and component quantity.
2Strength
If the lateral wall is seamlessly continuous, then strength and blocking property are improved, but manufacturing complexity increases
Solution Approach 1:
The metal sheet is segmented and folded along predetermined lines to form both the seamless lateral wall and the blocking portion. This segmentation approach enables the creation of a continuous seamless structure through controlled folds, resolving the contradiction between achieving seamless strength and maintaining manufacturing simplicity.
Solution Approach 2:
The blocking portion is formed by folding the metal sheet in the vertical dimension rather than adding a separate horizontal component. This dimensional transformation creates the blocking function within the existing lateral wall structure, maintaining seamlessness while simplifying manufacturing.
3Ease of manufacture
If multiple components are used, then ease of manufacture is improved, but assembly time and production cost increase
Solution Approach 1:
Multiple functional elements (lateral wall and blocking portion) are combined into a single manufactured component. This eliminates the need for separate fabrication and assembly steps, directly improving assembly speed and productivity while maintaining manufacturing ease through single-sheet processing.
4Ease of manufacture
If the lateral wall and blocking portion are integrated, then production cost is reduced, but shielding effectiveness may be compromised
Solution Approach 1:
The metal sheet is segmented and folded to create distinct functional zones - the lateral wall for structural support and the blocking portion for electromagnetic shielding. This segmentation ensures that each function is properly fulfilled while maintaining the cost benefits of a single integrated component.
Solution Approach 2:
Different portions of the integrated metal sheet are given different local qualities through folding - the lateral wall portions provide structural continuity while the blocking portion folds create electromagnetic shielding barriers. This local differentiation maintains shielding effectiveness within the integrated structure.
