Solution Overview
Problem
Existing clamping connections lack optimized force distribution, leading to inefficiencies in securing and transmitting torque effectively.

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a clamping connection is used to secure a shaft to a hub, then the connection provides force-locking capability, but the force distribution around the circumference is not optimized
Solution Approach 1:
The clamping ring is segmented with axial slots that divide the clamping force into distinct zones. These slots allow independent force application at different circumferential positions, enabling optimized force distribution around the shaft circumference while maintaining overall clamping strength
Solution Approach 2:
The clamping connection incorporates local structural variations including axial slots at specific positions, a disc with controlled thickness in the slot, and a retaining ring with specific geometric features. These local modifications create targeted force distribution zones without requiring complete redesign of the entire clamping structure
2Strength
If the hub is made rigid to maintain structural integrity, then strength is improved, but elastic deformation during clamping is reduced
Solution Approach 1:
The hub incorporates axial slots that enable controlled elastic deformation during the clamping process. These slots allow the hub to deflect and adapt to the clamping force while maintaining overall structural integrity, creating a semi-dynamic structure that transitions from rigid to flexible under load
3Manufacturing precision
If the disc thickness is increased to improve positioning accuracy, then manufacturing precision is improved, but the disc may interfere with the hub slot
Solution Approach 1:
The disc thickness is precisely controlled within specific dimensional ranges (e.g., 2-5mm) to achieve optimal positioning accuracy. The thickness parameter is carefully selected to provide sufficient rigidity for positioning while remaining thin enough to fit within the hub slot clearance, eliminating interference issues
4Length of moving object
If the retaining ring is positioned close to the disc to reduce assembly length, then device compactness is improved, but the locking reliability may be compromised
Solution Approach 1:
The retaining ring and disc are positioned at different axial locations along the shaft, utilizing the axial dimension to separate their functions. This spatial separation in the axial direction allows both components to perform their locking functions reliably while maintaining a compact overall assembly length through optimized dimensional coordination
