Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If welded flanges are used on cross braces to accommodate screws for longitudinal braces, then the connection is structurally simple, but the design lacks flexibility and welding seams create weak points that fail under vibration loads
Solution Approach 1:
The invention extracts the welding operation from the connection design, eliminating welded flanges and replacing them with a pure mechanical clamping system. The clamping device comprises a clamping element that engages with the cross brace and longitudinal brace without any welding, thereby removing the weak welding seams while maintaining structural integrity under vibration loads.
Solution Approach 2:
The clamping device incorporates adjustable clamping elements that can be tightened or loosened to accommodate different operational requirements. This dynamic adjustment capability allows the connection to adapt to varying load conditions and maintain optimal clamping force, improving reliability without compromising manufacturing simplicity.
2Reliability
If multiple solid clamping elements are provided to withstand high loads, then bearing security against vibration loads is improved, but the device complexity and number of components increase
Solution Approach 1:
The invention merges multiple clamping functions into a single integrated clamping device. The clamping device comprises a clamping element that simultaneously performs clamping, positioning, and load-bearing functions, eliminating the need for multiple separate clamping elements while maintaining the required bearing security against vibration loads.
Solution Approach 2:
The clamping element is designed as a multi-functional component that serves multiple purposes: it provides clamping force to secure the longitudinal brace to the cross brace, positions the longitudinal brace accurately, and withstands high vibration loads. This universal design reduces the total number of components needed in the structure.
3Force
If a large number of clamping elements are used to ensure bearing security, then the connection can withstand high loads, but the clamping connection becomes less compact and more complex
Solution Approach 1:
The invention combines multiple load-bearing functions into a single compact clamping device. The clamping element is designed to distribute and withstand high loads through its geometric configuration and material properties, eliminating the need for multiple separate clamping elements and achieving a compact connection design.
Solution Approach 2:
The clamping element may utilize composite material structures or optimized material compositions to achieve high load-bearing capacity in a compact form. This allows the single clamping element to withstand high vibration loads and forces without requiring multiple larger components, maintaining compactness while ensuring sufficient force resistance.
