Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the module is made of plastic material with large capacity and width, then the storage capacity and functionality are improved, but the module becomes prone to deformation due to bending
Solution Approach 1:
The module combines plastic material for the main body with metal material for the front adapter plate, creating a composite structure that leverages the light weight and molding advantages of plastic while incorporating the high strength and deformation resistance of metal in critical areas.
Solution Approach 2:
Instead of making the entire module from metal to prevent deformation, the invention applies metal material specifically to the front adapter plate where structural strength is most needed, while maintaining plastic material for the rest of the module to preserve its manufacturing advantages.
2Strength
If the front adapter plate is made of metal material, then the structural strength and resistance to deformation are improved, but the manufacturing complexity and assembly difficulty increase
Solution Approach 1:
The module is divided into separate components: a plastic casing and a metal front adapter plate. This segmentation allows each part to be manufactured independently using optimal processes for that material, then assembled together, combining the benefits of both materials without the complexity of manufacturing a monolithic structure.
Solution Approach 2:
The metal front adapter plate serves multiple functions: providing structural strength to prevent deformation, serving as a mounting surface for connectors, and enabling lateral screwing attachment to the plastic casing. This multi-functionality reduces the need for additional components.
3Adaptability or versatility
If the module design allows reversible mounting with pivot axis on left or right, then the adaptability and storage efficiency are improved, but the device complexity increases
Solution Approach 1:
The module employs asymmetric pivot arrangements where the pivot axis can be positioned on either the left or right side. This asymmetric design enables the same module to be mounted in different orientations (clockwise or anti-clockwise rotation) without requiring different module designs, thereby improving adaptability while maintaining a standardized module structure.
