Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If loops are interconnected at a distance from the fabric to form a coherent abrasive area, then abrading efficiency and quality are improved, but the structural complexity increases
Solution Approach 1:
The abrasive product is divided into multiple flexible loops that are interconnected at their heads, forming a segmented yet coherent abrasive area. Each loop acts as an independent unit that can adapt to surface irregularities while the interconnection provides overall structural coherence, resolving the contradiction between complexity and performance.
Solution Approach 2:
The loops are interconnected at a distance from the fabric, creating a three-dimensional structure rather than a flat two-dimensional arrangement. This spatial arrangement allows the abrasive area to protrude from the fabric surface, enabling better contact with irregular surfaces while maintaining flexibility, thus improving abrading efficiency without excessive complexity.
2Manufacturing precision
If the abrasive area is elevated at a distance from the fabric to adapt to surface irregularities, then abrading quality improves, but the stability of the structure may be compromised
Solution Approach 1:
The loops are designed to be flexible, allowing them to bend and adapt to surface irregularities while maintaining their elevated position relative to the fabric. This flexibility enables the abrasive area to conform to the workpiece surface, improving abrading quality, while the flexible nature also provides resilience and stability during operation.
Solution Approach 2:
The interconnection of loop heads merges multiple flexible elements into a unified abrasive area that maintains both adaptability and stability. The combined structure allows the abrasive area to respond to surface irregularities while the interconnected nature provides mutual support, enhancing overall structural stability.
3Productivity
If loops are made flexible to adapt to surface irregularities, then abrading efficiency improves, but the lifetime of the abrasive product may be reduced
Solution Approach 1:
The loops are designed with flexible properties that allow them to dynamically adapt to surface irregularities during operation. This flexibility enables the abrasive area to maintain optimal contact with the workpiece, improving abrading efficiency, while the flexible construction also allows the loops to recover and maintain their functionality over extended periods, preserving product lifetime.
