Offset Pipe Fitting Layout for Exterior Wall Leak Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional pipe fittings located within concrete exterior walls are prone to leaks, which can go undetected for extended periods, leading to increased cleanup costs and potential contamination of the concrete blocks.
Innovation Solution
A pipe fitting design featuring an entry hub, an offset exit hub, a coaxially aligned cleanout hub, and a main body with specific length and diameter ratios, allowing the exit hub to be positioned outside the structure, thereby preventing leaks within the exterior wall.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the pipe fitting is placed within the exterior wall to save space and simplify installation, then the installation complexity is reduced, but the risk of undetected leaks increases and cleanup costs increase
Solution Approach 1:
The invention extracts the problematic connection point from the interior wall and relocates it to the exterior environment. The pipe fitting is designed with an extended outlet that protrudes through the exterior wall, allowing the connection between the pipe fitting and sewer pipe to be made outside the structure. This extraction eliminates the risk of concealed leaks within the wall while maintaining simple installation procedures.
2Ease of operation
If the pipe fitting is placed within the exterior wall to simplify installation, then installation ease is improved, but cleanup costs and contamination risk increase
Solution Approach 1:
The harmful potential of leaks is extracted from the building interior by extending the pipe fitting outlet through the exterior wall. The connection point is relocated to an external position where any leakage would be immediately visible and contained outside the structure, eliminating the risk of contamination to interior spaces and avoiding expensive cleanup operations.
3Reliability
If the exit hub is positioned outside the structure to prevent leaks, then leak prevention is improved, but the pipe fitting design complexity increases
Solution Approach 1:
The invention resolves the contradiction by transitioning the connection point from a two-dimensional plane (within the wall) to a three-dimensional external position. The pipe fitting incorporates an extended outlet that protrudes through the exterior wall, creating a spatial separation between the fitting body and the connection point. This dimensional change allows the connection to be made outside the structure, preventing leaks while maintaining relatively simple fitting design.

AI summary
A pipe fitting includes an entry hub, an exit hub, and a cleanout hub. The cleanout hub is coaxially aligned with the exit hub and angularly offset from the entry hub. The pipe fitting also includes a main body that extends between the cleanout hub and the exit hub. The main body defines a main body length that is at least three times greater than the exit hub outer diameter.
