Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If steel is used in anchoring systems, then material cost is reduced, but corrosion resistance deteriorates
Solution Approach 1:
The invention uses titanium instead of steel, representing a material substitution that provides superior corrosion resistance while maintaining structural integrity. Titanium forms a protective oxide layer that prevents crevice corrosion in marine environments, directly addressing the corrosion resistance deterioration issue while the design optimizes material quantity to control costs.
2Reliability
If titanium is used in anchoring systems, then corrosion resistance is improved, but material cost increases
Solution Approach 1:
The fastening device is divided into multiple components (frame, clamping sleeve, elastic elements) that can be optimized individually. This segmentation allows for efficient use of expensive titanium material only where critical for corrosion resistance and structural function, while reducing overall titanium quantity through optimized design and material distribution throughout the device.
Solution Approach 2:
The invention changes the material parameter from steel to titanium, which fundamentally alters the corrosion resistance property. This parameter change is complemented by design modifications that reduce the total volume of titanium required, thereby improving corrosion resistance while controlling material costs through optimized material usage.
3Ease of manufacture
If screw joints are used in fastening devices, then ease of assembly is improved, but crevice corrosion increases
Solution Approach 1:
The invention extracts and removes screw joints from the fastening device design. Instead of using traditional screw connections that create crevices susceptible to corrosion, the device employs a clamping sleeve mechanism with elastic elements that achieve secure fastening without penetrating fasteners, thereby eliminating the crevice corrosion problem while maintaining ease of assembly through a simplified single-piece titanium construction.
4Reliability
If multiple working operations are performed for tightening screw joints, then fastening reliability is improved, but worker health risks increase
Solution Approach 1:
The fastening device employs elastic elements (springs) that automatically provide the necessary clamping force and maintain fastening reliability without requiring manual tightening operations. The elastic elements self-adjust to maintain proper fastening pressure, eliminating the need for workers to perform repetitive tightening operations with tools, thereby reducing health risks while preserving fastening reliability through the self-regulating elastic mechanism.
