Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a connecting sleeve with integral tab and groove for locking element is used, then anti-rotation and locking functionality is achieved, but the structure becomes complex and manufacturing cost increases
Solution Approach 1:
The invention extracts the locking and anti-rotation functionality from a complex integrated design and implements it through a separate locking sleeve component that wraps around the connecting sleeve. The locking sleeve with its projections and recesses provides the same functionality but with a simpler overall structure that is easier and cheaper to manufacture.
2Device complexity
If a locking sleeve with integrally formed anti-rotation projections and locking recesses is used, then manufacturing cost is reduced and structure is simplified, but assembly complexity may increase
Solution Approach 1:
The invention merges the anti-rotation projections and locking recesses into a single integrally formed locking sleeve component. This integration simplifies manufacturing by reducing the number of parts and assembly steps, while the snap-fit connection mechanism ensures easy and reliable assembly without requiring complex tools or procedures.
3Strength
If a metallic locking sleeve with force-fit connection is used, then connection strength and reliability are improved, but manufacturing cost and processing difficulty increase
Solution Approach 1:
The invention utilizes parameter changes in the form of interference fit (force-fit) between the locking sleeve and connecting sleeve. By carefully selecting dimensional parameters and material properties, the design achieves strong mechanical connection through elastic deformation and friction, providing high connection strength while remaining manufacturable with standard metal forming processes.
