Split T-Pipe Housing Clamp for Diameter Stability and Pipe Fit
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional housing devices for fluid pipes face challenges in maintaining a consistent diameter when subjected to separating forces, leading to potential separation from the pipe due to reduced gap sizes, and are limited in accommodating pipes of varying diameters.
Innovation Solution
The housing device features an annular case with split portions and a clamp, where protrusions are formed only at the ends of the case in the circumferential direction, allowing for a smaller gap at the split portion ends to prevent diameter reduction and enabling adjustment to accommodate different pipe diameters through the actuation of the clamp.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If protrusions are formed at all locations on joint surfaces to suppress diameter reduction, then diameter stability is improved, but adaptability to different pipe diameters deteriorates
Solution Approach 1:
The patent applies local quality by forming protrusions only at specific locations (joint surfaces at ends of the case) rather than uniformly across the entire case. This localized approach allows the protrusions to suppress diameter reduction at critical areas while leaving other areas flexible for adjustment, thereby resolving the contradiction between diameter stability and adaptability to different pipe diameters.
2Stability of the object's composition
If the gap at the split portion is made small to suppress diameter reduction, then diameter stability is improved, but the ability to accommodate varying pipe diameters deteriorates
Solution Approach 1:
The patent creates locally small gaps at the joint surfaces where protrusions are formed, while maintaining larger gaps in other regions. This localized gap control suppresses diameter reduction at critical areas while preserving the ability to adjust the overall gap size to accommodate different pipe diameters, resolving the contradiction between diameter stability and adaptability.
3Force
If the case diameter is reduced due to compression from separating force, then the separating force effect is amplified, but the restraint fixture may become separated from the housing device
Solution Approach 1:
The patent applies preliminary anti-action by forming protrusions at the joint surfaces that preemptively counteract the diameter reduction effect before it can occur. These protrusions maintain the case diameter even when compression forces act on the sealing material, preventing the chain reaction that would lead to restraint fixture separation and thereby improving connection reliability.

Function Achieved in This Case
This design effectively suppresses diameter reduction under separating forces, allows for uniform compression of sealing material, and accommodates pipes of varying diameters, preventing separation of the restraint fixture from the housing device.

AI summary
A split T-shaped pipe serving as a housing device and comprising: an annular case body that has a split part in at least one location in the circumferential direction, and that surrounds the outer circumferential surface of a water pipe in a sealed state with a seal material therebetween; and fasteners for tightening the split part, thereby joining a plurality of split pieces constituting the case body. Joining surfaces are provided at the circumferential end portions of the split pieces, and protrusions protruding along the circumferential direction are formed on the joining surfaces but only at both end portions of the case body in the pipe axis direction of the water pipe.
