Segmented Compression Fitting for Single-Tool Tightening
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pipe fittings require multiple wrenches for tightening, which can be difficult due to excessive torque and limited space, making the process cumbersome.
Innovation Solution
A compression fitting with a first and second fitting segment and a grip ring, where a fastener assembly is non-rotatable, allowing for easy tightening using a power tool and indicating proper engagement through contact between ends.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional pipe fittings are tightened using two wrenches, then the connection is secured, but the operation becomes difficult due to excessive torque and limited space
Solution Approach 1:
The fitting is divided into two separate segments that can be independently positioned and secured. This segmentation allows each segment to be tightened separately using a single power tool, eliminating the need for two wrenches and reducing space requirements while maintaining secure connection through the interlocking segments
Solution Approach 2:
The manual two-wrench mechanical tightening system is replaced with a power tool-driven fastening mechanism. The power tool automatically applies the required torque to secure the segments together, eliminating the need for operators to manually overcome excessive torque and navigate limited space with traditional wrenches
2Reliability
If multiple wrenches are used for tightening pipe fittings, then the fastening is achieved, but the process becomes cumbersome and time-consuming
Solution Approach 1:
By dividing the fitting into separable segments with dedicated fastening interfaces, the design enables rapid assembly where each segment can be quickly secured using a single power tool, significantly reducing installation time compared to traditional multi-wrench methods while ensuring reliable fastening
Solution Approach 2:
The fitting segments are pre-configured with integrated fastening features and alignment elements that prepare the connection for rapid assembly. This preliminary design allows the segments to be quickly joined and secured without requiring complex manual manipulation or multiple tools, thereby improving installation efficiency

AI summary
A compression fitting includes a first fitting segment defining a first arcuate central section, a first retention rib extending radially inward from the first arcuate central section; a second fitting segment defining a second arcuate central section, a second retention rib ending radially inward from the second arcuate central section; and a grip ring defining a first ring end and a second ring end, wherein a split is defined between the first ring end and the second ring end, and wherein the first ring end engages the first retention rib and the second ring end engages the second retention rib.
