Offset Urinal Piping With Rotatable Flange for Finished Walls
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pipe connectors require direct installation on drainpipes behind finished walls, necessitating wall demolition for adjustments, and lack the ability to adjust drainpipe position relative to the wall or comply with ADA requirements without damaging the finished wall.
Innovation Solution
A pipe connector with offset portions and a rotatable flange that allows for adjusting the drainpipe's position relative to the wall without damaging the finished wall, using PVC or ABS materials, and accommodating urinal installation heights and ADA compliance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If brackets are installed directly on drainpipes behind finished walls, then proper coupling to drainpipe is achieved, but wall demolition is required for installation or adjustment
Solution Approach 1:
The piping device is divided into multiple segments: a first portion for coupling to the drainpipe, a second portion for positioning relative to the wall, and a middle portion connecting them. This segmentation allows the first portion to be installed on the drainpipe while the second portion provides adjustable positioning, eliminating the need to demolish the wall for installation or adjustments.
Solution Approach 2:
The middle portion of the pipe is designed to be flexible or adjustable, allowing the second portion to be positioned at different locations and orientations relative to the wall. This dynamic capability enables the device to adapt to various installation scenarios without requiring wall demolition, while still maintaining reliable coupling to the drainpipe through the first portion.
2Productivity
If drainpipe position is fixed during wall finishing, then wall construction is simplified, but adjustments are impossible without damaging the finished wall
Solution Approach 1:
The adjustable middle portion allows the second portion to be dynamically repositioned after the wall is finished. This enables corrections to drainpipe positioning errors or adaptations to changes in floor thickness without damaging the finished wall, while the fixed first portion maintains stable coupling during wall construction.
Solution Approach 2:
The device introduces an additional dimensional degree of freedom through the adjustable middle portion, allowing the second portion to be positioned at various locations and angles relative to the wall. This extra dimension of adjustability enables corrections to positioning errors without requiring demolition of the finished wall.
3Ease of operation
If standard piping is used, then installation is straightforward, but compliance with ADA requirements cannot be achieved when floor thickness changes
Solution Approach 1:
The adjustable middle portion provides the flexibility needed to comply with ADA requirements by allowing the second portion to be repositioned if floor thickness changes. This maintains installation simplicity while achieving the required adaptability for accessibility compliance.
Solution Approach 2:
The device allows changes in positional parameters of the second portion relative to the wall and floor. This enables adaptation to different floor thicknesses and compliance with ADA height requirements while maintaining a straightforward installation process through the standardized first portion coupling.

AI summary
An offset piping device for relocating a sewer stub-out for a urinal without damaging a finished wall includes a pipe having a first portion, a second portion, and a middle portion extending therebetween. The middle portion is angled relative to the first and second portions whereby the first portion is offset from the second portion. A flange is rotatably coupled to the second portion. The flange can be used to couple a urinal to a wall when the first portion is being coupled with a drainpipe for the urinal. Because the first portion is offset from the second portion, access for the drainpipe relative to the wall is adjusted.
