Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing connection systems for pipes to main pipes, especially those renovated with inliners, face challenges in ensuring tightness and universality across various pipe wall thicknesses, requiring a solution that is easy to install, cost-effective, and provides high reliability.
Innovation Solution
A connection system featuring a hollow plug-shaped installation insert with a widened end section and bent tab, incorporating multiple fixing and contact elements, a sealing element that swells with water, and a flexible fixing means, allowing secure contact with the inliner and main pipe surfaces, thus ensuring tightness and adaptability across different pipe thicknesses.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a connection system uses a simple elastomer insert to achieve tightness, then the installation is easy and cost-effective, but it cannot prevent liquid penetration into the gap between the inliner and main pipe
Solution Approach 1:
The connection system is divided into multiple functional components: an installation insert with sealing elements for the transverse opening, and a separate inliner seal for preventing liquid penetration into the gap between the inliner and main pipe. This segmentation allows each component to perform its specific sealing function effectively.
Solution Approach 2:
The installation insert acts as an intermediary component between the transverse opening and the inliner, providing a sealing bridge that prevents liquid from penetrating into the gap between the inliner and main pipe while maintaining the simplicity of the overall connection system.
2Adaptability or versatility
If the connection system is designed to be universal for various pipe wall thicknesses, then it increases adaptability, but it increases device complexity
Solution Approach 1:
The installation insert is designed with a universal structure that can accommodate different pipe wall thicknesses. The inliner seal and sealing elements are configured to adapt to various dimensions, allowing the same connection system to be used across different pipe specifications without requiring multiple specialized components.
Solution Approach 2:
The connection system utilizes parameter changes in the inliner seal dimensions and positioning to adapt to different pipe wall thicknesses. By adjusting the seal parameters rather than changing the overall system structure, the system maintains simplicity while achieving universality.
