Pipe Connection Insert for Sealing Reinforced Concrete Openings
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing connection systems for pipes to steel-reinforced concrete main pipes fail to ensure tightness and protect the reinforcement from moisture and oxygen, leading to potential damage or destruction, and lack universality across varying pipe wall thicknesses.
Innovation Solution
A connection system featuring a hollow, partially soft installation insert with a conical screw area and an extension mechanism that includes arrow-shaped or mushroom-shaped connecting means, providing a firm and fluid-tight seal, and using polymer materials for durability and ease of installation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a connection system is installed on a steel-reinforced concrete main pipe, then tightness at the transverse opening is achieved, but the exposed steel reinforcement is exposed to moisture and oxygen causing rust and potential destruction
Solution Approach 1:
The patent applies this principle by using a flexible membrane that extends from the connection system to cover the exposed steel reinforcement on the inner surface of the main pipe. This membrane creates a protective barrier that prevents moisture and oxygen from reaching the reinforcement, thereby eliminating the harmful effect while maintaining the tightness function.
Solution Approach 2:
The patent extends the protective function into a new spatial dimension by adding a membrane that covers the reinforcement area. This dimensional extension transforms the connection system from merely providing tightness to also providing corrosion protection, addressing both requirements simultaneously.
2Adaptability or versatility
If different pipe wall thicknesses are accommodated, then universality across main pipes is achieved, but the complexity of ensuring protection for varying reinforcement exposure increases
Solution Approach 1:
The patent applies this principle by using an extensible membrane that can dynamically adjust its length to match different pipe wall thicknesses. The membrane can be extended or shortened as needed, allowing the same connection system design to universally accommodate various main pipe specifications without increasing structural complexity.
Solution Approach 2:
The patent changes the parameter of membrane length to adapt to different pipe wall thicknesses. By making this single parameter adjustable, the system achieves universality across different main pipe specifications while maintaining a simple and consistent structural design.
3Object-affected harmful factors
If the end section of the installation insert is extended to cover reinforcement, then protection from moisture and oxygen is achieved, but the complexity of the connection system increases
Solution Approach 1:
The patent merges the protective function with the existing membrane structure of the connection system. Instead of adding a separate protective component, the membrane is integrated into the connection system design, allowing it to serve both as part of the sealing mechanism and as the protective barrier for the reinforcement.
Solution Approach 2:
The patent recovers and repurposes the membrane material already present in the connection system for an additional protective function. The membrane is extended beyond its original sealing role to also cover and protect the exposed reinforcement, effectively using existing material for dual purposes.
