Steel Ring Tooth Group Layout for Pipe Fitting Locking Force
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing steel rings used in compression pipe fittings fail to generate sufficient locking force, leading to inadequate fixing and increased stress on manufacturing dies, resulting in processing difficulties and higher costs.
Innovation Solution
A steel ring design featuring a locking mechanism with inclined locking teeth arranged in multiple groups, providing a greater locking force and uniform stress distribution during manufacturing, allowing for increased die service life and reduced production costs.

Engineering Contradiction Analysis
1Force
If conventional locking components are used on the steel ring, then the structure is simple, but the locking force generated is insufficient
Solution Approach 1:
The locking component is segmented into multiple locking teeth (first locking tooth group and second locking tooth group) with different orientations. The first locking tooth group has teeth inclined at a first angle to the axial direction, while the second locking tooth group has teeth inclined at a second angle (different from the first angle). This segmentation allows different portions of the pipe to engage with differently oriented teeth, distributing the locking force across multiple contact points and directions, thereby generating greater overall locking force while maintaining a relatively simple integrated ring structure.
Solution Approach 2:
The locking teeth are designed with asymmetric inclination angles relative to the axial direction. The first locking tooth group has teeth inclined at a first angle, while the second locking tooth group has teeth inclined at a second angle that differs from the first angle. This asymmetric design allows the locking component to generate locking force in multiple directions and orientations, maximizing the engagement with the pipe surface and increasing the overall locking effectiveness without requiring a completely complex mechanism.
2Force
If asymmetric locking components are used to increase locking force, then the locking force improves, but the stress on the stamping die becomes unbalanced causing die damage
Solution Approach 1:
The locking teeth are designed with asymmetric inclination angles relative to the axial direction. The first locking tooth group has teeth inclined at a first angle, while the second locking tooth group has teeth inclined at a second angle that differs from the first angle. This asymmetric design allows the locking component to generate locking force in multiple directions and orientations, maximizing the engagement with the pipe surface and increasing the overall locking effectiveness without requiring a completely complex mechanism.
Solution Approach 2:
Different portions of the locking component have different local characteristics - the first locking tooth group has teeth with a first inclination angle suited for engaging one portion of the pipe, while the second locking tooth group has teeth with a second inclination angle suited for engaging another portion of the pipe. This local differentiation optimizes the locking force generation at each contact point while the overall symmetric arrangement of these groups maintains balanced stress distribution during manufacturing.
3Force
If multiple locking tooth groups with different inclination angles are used, then the locking force increases, but the manufacturing complexity increases
Solution Approach 1:
The locking component is segmented into multiple locking tooth groups (first locking tooth group and second locking tooth group) with different orientations. The first locking tooth group has teeth inclined at a first angle to the axial direction, while the second locking tooth group has teeth inclined at a second angle (different from the first angle). This segmentation allows different portions of the pipe to engage with differently oriented teeth, distributing the locking force across multiple contact points and directions, thereby generating greater overall locking force while maintaining a relatively simple integrated ring structure.
Solution Approach 2:
Multiple locking tooth groups with different inclination angles are merged into a single integrated locking component on the steel ring. The first locking tooth group and second locking tooth group are combined in one piece, allowing the component to be manufactured as a single unit through processes like stamping or casting. This merging reduces the number of separate parts that need to be assembled and simplifies the manufacturing process while still providing the enhanced locking force of multiple tooth orientations.

AI summary
A steel ring includes a locking component. The locking component is provided on an inner surface of a ring body in a protruding manner. The locking component includes locking teeth, and the locking tooth is sheet-like and includes a fixed part and a contact part. Multiple locking teeth constitute a first locking tooth group, and with regard to the locking teeth in the first locking tooth group, the distance between the fixed parts is smaller than the distance between the contact parts. Multiple locking teeth constitute a second locking tooth group, and with regard to the locking teeth in the second locking tooth group, the distance between the fixed parts is greater than the distance between the contact parts. The ring body has a first state and a second state. When the ring body is in the first state, the ring body is in an unclosed annular shape, and when the ring body is in the second state, the ring body is in a closed annular shape.
