Reinforced Clamping Ring Structure for High-Strength PVC Pipe Securing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing clamping rings have limited hardness and tensile strength, making them unsuitable for securing polyvinyl chloride (PVC) pipes, and those with corundum have limited tensile strength.
Innovation Solution
A method involving an insert ring with reinforcement elements, where the insert ring is overmolded with a material, and the sacrificial ring is mechanically processed to produce a clamping ring with a combination of flexibility and high tensile strength, using reinforcement elements that are flush with the inner diameter and connected in a form-fitting manner.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If conventional clamping rings are used, then flexibility is maintained, but hardness and tensile strength are limited
Solution Approach 1:
The clamping ring is manufactured as a composite structure by encasing an insert ring (comprising a sacrificial ring and reinforcing elements) with molding material. The reinforcing elements, which extend through the molding material, provide enhanced tensile strength and hardness, while the molding material maintains flexibility and deformability. This composite construction resolves the contradiction between strength and structural simplicity.
2Strength
If reinforcing elements are added to the insert ring, then tensile strength improves, but manufacturing complexity increases
Solution Approach 1:
The insert ring with reinforcing elements is prepared in advance as a pre-assembled component before the encasement process. The retaining devices are pre-formed on the reinforcing elements, and the entire insert ring structure is ready for integration into the molding material in a single step, simplifying the overall manufacturing process despite the complexity of the final structure.
Solution Approach 2:
The manufacturing process merges multiple functions into a single encasement step: the insert ring is positioned, the molding material is injected to encase the insert ring and bonding agents, and the reinforcing elements are simultaneously integrated with the molding material through positive locking. This combining of operations reduces the number of separate manufacturing steps.
