Solution Overview
Problem
Existing spinning ring manufacturing methods often result in increased manufacturing expenditure due to the need for assembling multiple components with high accuracy, and the design is only adapted to the final use, neglecting the optimal process sequence and properties required.
Innovation Solution
A one-piece spinning ring with a foot flange, annular crown, and web is produced using a deep-drawing process, where the web's transition radii are optimized to minimize manufacturing effort and enhance torsional strength, allowing for cost-effective and high-quality production with improved dimensional accuracy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple components are assembled to produce spinning rings, then the design can be adapted to final use requirements, but the manufacturing expenditure and complexity increase due to the need for high-precision assembly
Solution Approach 1:
The patent merges multiple components (foot flange, web, and ring crown) into a single integrated spinning ring structure. This one-piece construction eliminates the need for separate assembly operations while maintaining the ability to adapt the design to different final use requirements through optimized geometry and material selection in the single component.
Solution Approach 2:
The integrated spinning ring design serves multiple functions within a single component: the foot flange provides mounting functionality, the web provides structural connection, and the ring crown provides the operational surface. This multi-functional integration reduces manufacturing complexity while maintaining design adaptability for various applications.
2Ease of manufacture
If deep-drawing process is used to produce the entire spinning ring, then manufacturing effort is reduced, but the transition areas may develop cracks due to material deflection
Solution Approach 1:
The patent optimizes the geometric parameters of the transition areas, specifically setting the outer radius between 0.2 to 0.4 mm and the inner radius between 1.0 to 1.5 mm. These parameter changes reduce material deflection during deep-drawing while maintaining structural integrity, preventing crack formation in the transition zones between the foot flange, web, and ring crown.
Solution Approach 2:
The patent introduces curved transition areas with specific radii at the junctions between different components. These curved transitions distribute stress more evenly during the deep-drawing process compared to sharp corners, reducing the risk of crack formation while maintaining the integrated structure's strength and reliability.
3Volume of moving object
If the web transition radii are minimized for compact design, then the spinning ring size is reduced, but the torsional strength decreases
Solution Approach 1:
The patent establishes optimal parameter ranges for the web transition radii (outer radius: 0.2-0.4 mm, inner radius: 1.0-1.5 mm) that balance compactness and torsional strength. These optimized parameters maintain sufficiently large transition areas to resist torsional forces while keeping the overall spinning ring size compact for the application.

Function Achieved in This Case
The one-piece deep-drawing process reduces manufacturing costs and enhances the dimensional accuracy and torsional strength of the spinning ring, enabling efficient production and adaptation to various applications without compromising the ring's properties.
Implementation Method 1
The deep-drawing process comprises a combination of deep-drawing and pressing or upsetting processes. In this deep-drawing process, a blank is produced which includes the base flange and the web in their finished form and the ring crown in its raw state.
