Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If layers are connected rigidly to maintain structural integrity, then strength is improved, but relative movement under impact is restricted
Solution Approach 1:
The connector is divided into separate functional components: attachment parts for securing layers, connecting means for detachable linkage, and low friction layers for enabling relative movement. This segmentation allows each component to optimize its specific function while working together to achieve both structural integrity and relative movement capability.
Solution Approach 2:
The connector transitions from a static rigid connection to a dynamic system where the low friction layer enables relative movement between layers during impact. The detachable connecting means allows the structure to adapt its configuration based on impact forces, providing both stability and movement capability.
2Adaptability or versatility
If complex connecting structures are used to allow relative movement, then adaptability is improved, but device complexity increases
Solution Approach 1:
The low friction layer is applied locally at the interface where relative movement is needed, rather than making the entire connector complex. This localized approach enables relative movement only where required while keeping the rest of the connector structure simple and straightforward.
Solution Approach 2:
The low friction layer acts as an intermediary element between the two layers, mediating the relative movement without requiring complex mechanical linkages. This simple intermediary component solves the relative movement problem while minimizing overall device complexity.
3Ease of manufacture
If detachable connecting means are used to facilitate assembly, then ease of manufacture is improved, but connection reliability may be compromised
Solution Approach 1:
The connector is designed with pre-configured attachment parts and connecting means that are prepared in advance for easy assembly. The detachable design allows for straightforward manufacturing and assembly processes while maintaining reliable connection through the low friction layer and attachment mechanisms.
