Split Snap-Lock Pipe Fitting for Fast Wall Sealing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional sealing devices for underground storage tank systems fail to provide a quick and efficient method for attaching a fitting around a pipe without manually holding the fitting in place while adhesives or solvent welds cure.
Innovation Solution
A snap-lock fitting composed of two half portions that join together around a pipe, featuring a snap ridge and snap recess mechanism for secure attachment and alignment, allowing for easy installation without manual holding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional sealing devices are used, then the pipe can be sealed through the wall, but the installer must manually hold the fitting in place while adhesive or solvent weld cures
Solution Approach 1:
The fitting is divided into two separate half-portions that can be independently handled and positioned around the pipe. Each half-portion can be separately installed and then joined together through the interlocking ridge and recess mechanism, eliminating the need for manual holding during adhesive curing.
Solution Approach 2:
The ridge and recess configuration creates a self-aligning and self-securing mechanism. When the two half-portions are brought together, the ridge automatically engages with the recess, providing self-positioning and self-locking that eliminates the need for manual holding while the adhesive cures.
2Productivity
If conventional sealing devices are used, then the pipe can be sealed, but the installer must manually hold the fitting in place during curing
Solution Approach 1:
Dividing the fitting into two manageable half-portions improves installation efficiency by allowing each half to be independently positioned and secured to the pipe before joining. The segmentation enables a systematic installation process that is more efficient than handling a single complex piece.
Solution Approach 2:
The ridge and recess features merge the alignment and securing functions into a single integrated mechanism. This combination of features provides both positioning and locking capabilities without requiring separate components, thereby managing complexity while improving productivity.
3Ease of operation
If the fitting is designed as a single piece, then the structure is simple, but the installer cannot easily position and secure it around the pipe
Solution Approach 1:
Segmenting the fitting into two half-portions makes it easier to position around the pipe, as each half can be independently maneuvered into place. The segmented design allows installers to work with smaller, more manageable components that are simpler to position than a single large piece.
Solution Approach 2:
The asymmetric ridge and recess configuration enables the two half-portions to join in only one correct orientation, providing built-in alignment guidance. This asymmetric design simplifies the positioning process by eliminating the need for complex alignment procedures while increasing the fitting composition from one piece to two.

AI summary
Disclosed is a snap-lock fitting for encircling a pipe that passes through an opening and sealing the opening with respect to the pipe. The snap-lock fitting includes a pair of half portions that are configured to join together around a pipe. The half portions include at least one half-cylinder portion extending from a first end to a second end, where the at least one half-cylinder portion has a first mating surface with a ridge and a second mating surface with a recess, and where the ridge of a first of the pair of half portions is configured to engage a recess of a second of the pair of half portions. Also disclosed is a method of installing the snap-lock fitting.
