Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pipe coupling technologies face challenges in manufacturing complexity, assembly difficulty, and potential for leakage due to deformation of elastic rings, as well as issues with metal strips inside the clamp band limiting positioning flexibility.
Innovation Solution
A pipe coupling design featuring a flat, single-piece clamp band with longitudinal slots and a connection assembly comprising first and second connection parts, allowing for easy assembly and secure positioning of the inner housing, which includes recesses and projections for precise alignment and clamping, enabling robust and cost-effective production.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the inner housing consists of several individual segments spaced apart from each other, then the pipe coupling can be assembled, but the assembly process becomes massively complicated and time-consuming
Solution Approach 1:
The patent merges multiple housing segments into a single-piece inner housing. This eliminates the complexity of assembling multiple segments and their individual positioning holes, while maintaining the functional requirements of the housing structure. The single-piece design directly resolves the assembly complexity issue described in the contradiction.
2Reliability
If the elastic ring is arranged inside the housing segments, then sealing is provided, but the elastic ring becomes deformed and squeezed between the housing segments during clamping
Solution Approach 1:
The patent combines the housing segments into a single-piece inner housing, eliminating the gaps between segments that cause the elastic ring to deform and squeeze. This maintains the sealing function while preserving the integrity of the elastic ring during the clamping process.
Solution Approach 2:
The patent eliminates the harmful effect of segment gaps on the elastic ring by providing a continuous housing structure. The single-piece design prevents the elastic ring from being squeezed, thereby maintaining both sealing reliability and ring integrity.
3Stability of the object's composition
If the metal strips are fixed on the inside of the clamp band, then the clamp band is secured, but the clamp band cannot be positioned as desired while assembling the pipe clamp
Solution Approach 1:
The patent replaces fixed metal strips with a dynamic connection assembly that includes connection parts on the clamp band and corresponding connection parts on the inner housing. This allows the clamp band to be positioned flexibly during assembly while maintaining stability once assembled, resolving the contradiction between positioning flexibility and assembly stability.

AI summary
A pipe coupling for connecting two pipe ends includes: a clamp band which has a longitudinal slot, an inner housing arranged therein, and a clamping mechanism for reducing the internal diameter of the clamp band. The clamp band is designed as a flat single piece and has an outer band portion and inner band portions which are connected to the outer band portion via at least one connection. A connection assembly is provided for securing the inner housing in the clamp band, where the connection assembly includes a first connection part and a second connection part. The first connection part extends into the second connection part, and at least one of the connection parts of the connection assembly is designed to connect the at least first outer band portion to the at least first inner band portion of the clamp band.
