Pipe Connection Device With Integrated U-Shaped Holding Element
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pipe connection devices require complex pre-assembly and are tedious to use due to their multi-part design, which complicates the plug-in connection process.
Innovation Solution
A pipe connection device with a U-shaped holding element, where the side legs are connected in one piece to a partial shell, featuring a radially inwardly protruding projection for secure engagement with the connecting piece, and a secondary locking mechanism with barb attachments to ensure easy assembly and disassembly without pre-assembly, while protecting the holding element from external influences.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a multi-part design is used for pipe connection devices, then the device can be manufactured with standard components, but the pre-assembly becomes complex and tedious
Solution Approach 1:
The patent combines multiple separate components (partial shells, holding elements, and connecting pieces) into an integrated one-piece molded structure. The holding element is directly formed as part of the partial shell, eliminating the need for separate assembly of these components and thereby simplifying the overall assembly process while maintaining manufacturing feasibility through injection molding techniques.
2Ease of operation
If the holding element is exposed on the outside of the pipe connection device, then it is easily accessible for assembly and disassembly, but it becomes vulnerable to mechanical damage and external influences
Solution Approach 1:
The holding element is nested within the structure of the pipe connection device, specifically positioned within the space defined by the partial shells. This nested configuration allows the holding element to be accessible for its intended function while simultaneously being protected by the surrounding shell structure from external mechanical damage and environmental influences.
3Ease of operation
If a one-piece design is used for the holding element, then complex pre-assembly is eliminated, but the device requires integrated molding which may increase manufacturing complexity
Solution Approach 1:
The partial shell is designed to serve multiple functions simultaneously: it provides the structural housing for the pipe connection device, incorporates the holding element for securing the connecting piece, and integrates the necessary geometric features for assembly. This multi-functionality reduces the number of separate components needed, achieving simplification through integration rather than through complex specialized parts.

AI summary
The device (10) has a longitudinal section (2) comprising a radially and inwardly projecting projection (4). Multiple sub-shells (18a, 18b, 20) form a base form peripheral portion and are connected with each other via integrally molded hinges extending along direction of a cylinder axis. Locking units are cooperated with each other and provided at the sub-shells that are connected along a circumferential direction. A U-shaped holding unit (12) is designed as a U-shaped bracket, and free ends (23) of U-shaped side legs (24) are integrally connected with one of the sub-shells. An independent claim is also included for a pipe coupling assembly.
