Split Stub-Out Retainer for Pipe Support and Wall Hole Coverage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional plumbing methods result in oversize holes with rough edges in finished surfaces and lack support for flexible piping, leading to aesthetic and structural issues.
Innovation Solution
A stub out retainer system comprising interconnected clamp sections with escutcheon plates, collars, and beams that securely fit around pipes, providing support and covering enlarged wall openings, allowing for easy installation and finishing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If holes are made quickly with minimal effort in measuring and cutting, then installation speed is improved, but hole quality becomes poor (oversize with rough edges)
Solution Approach 1:
The device is divided into multiple components: a clamp body, a cover plate, and a finishing component. The clamp body is further segmented into opposing jaws that can independently adjust. This segmentation allows the rough hole-making process to be separated from the precision finishing process, enabling quick installation while achieving smooth, precise final holes through the finishing component
Solution Approach 2:
The device performs preliminary hole formation followed by immediate finishing in one continuous operation. The opposing jaws are preliminarily positioned to create the hole, then the finishing component is deployed to smooth and precision the hole edges before final installation, eliminating the need for separate precision drilling operations
2Adaptability or versatility
If flexible piping is used without brackets or restraints, then installation flexibility is improved, but structural support becomes insufficient
Solution Approach 1:
The device merges the clamping function and the support function into a single integrated structure. The clamp body with opposing jaws provides both the flexibility to accommodate different pipe positions and the structural strength to support flexible piping, eliminating the need for separate brackets or restraints
Solution Approach 2:
The clamp body serves multiple functions: it provides structural support for flexible piping, positions the pipe accurately, and works with the finishing component to create precise holes. This multi-functionality replaces the need for multiple separate components like brackets, restraints, and precision drilling equipment
