Segmented Lining Hose Closing Mechanism for Small Access Insertion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing closing mechanisms for lining tubes in piping systems are cumbersome and expensive due to their large size and weight, making it difficult to insert them through small access openings, which often requires costly enlargement of the opening.
Innovation Solution
A closing mechanism composed of separable ring segment shaped elements that can be connected to form a hollow cylinder, allowing for insertion through smaller openings and reducing weight for easier handling, with features like central angles of 120° and offset connection elements for secure interlocking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a traditional closing mechanism is used to seal the opening end of a lining tube, then the sealing function is achieved, but the mechanism becomes too heavy and large to insert through small access openings
Solution Approach 1:
The closing mechanism is divided into multiple separable ring segment shaped elements that can be inserted through small access openings individually and then connected to form a complete hollow cylinder. This segmentation allows the mechanism to pass through restricted openings while maintaining its sealing function when assembled.
Solution Approach 2:
The separable ring segments are designed to nest within each other during insertion through the access opening, allowing the complete closing mechanism to be introduced through a small opening and then expanded to its full functional form inside the piping system.
2Reliability
If a traditional closing mechanism is used to seal the opening end of a lining tube, then the sealing function is achieved, but the mechanism requires expensive enlargement of the access opening
Solution Approach 1:
By segmenting the closing mechanism into small ring elements that can be inserted through existing small access openings, the invention eliminates the need for expensive opening enlargement work, making the rehabilitation process more cost-effective.
3Reliability
If a traditional closing mechanism is used to seal the opening end of a lining tube, then the sealing function is achieved, but the mechanism becomes complex to connect within the tight space of a piping system
Solution Approach 1:
The segmentation into standardized ring segments with simple connection elements reduces the complexity of assembly within the confined piping space, as each segment has a straightforward connection interface that simplifies the overall assembly process.
