Hose Connector Plug Arrangement for Automated Pre-Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hose-pipe connectors are difficult to handle during assembly and are not suitable for automatic assembly lines, lacking a mechanism to securely hold components together until final assembly with the hose and pipe.
Innovation Solution
A connector arrangement comprising a front and rear tubular member with an O-ring and a plug that securely holds the components together, allowing for easier handling and assembly, including a pressure test before final assembly, and facilitating automatic assembly line processing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional connectors are assembled by inserting the connector into the hose and then pushing the pipe into the through-bore, then the connector can be assembled with basic components, but the connector is difficult to handle during assembly and not suitable for automatic assembly lines
Solution Approach 1:
The patent applies preliminary action by providing a holding mechanism that secures the connector components together before final assembly with the hose and pipe. This preliminary securing action makes the connector easier to handle during assembly and suitable for automatic assembly lines, as the components are pre-positioned and held in place rather than requiring manual manipulation during the assembly process
2Extent of automation
If the connector components are held together securely until final assembly, then automatic assembly line processing is facilitated, but the connector structure becomes more complex
Solution Approach 1:
The holding mechanism performs preliminary action by securing components together in advance, enabling automatic assembly line processing. The mechanism is designed to be simple yet effective, providing the necessary holding function without excessive structural complexity
Solution Approach 2:
The holding mechanism acts as an intermediary element between the connector components and the final assembly process. It temporarily secures the components together and is later removed or discarded after serving its purpose, facilitating automation without permanently increasing the connector's structural complexity

AI summary
A connector having an outer surface for engagement by a hose, an inner through-bore (13) for receiving a pipe nipple to be connected to the hose, and sealing means (12) for sealing the hose to the pipe nipple, characterised by a plug (15) having a shaft (16) adapted to be inserted into the through-bore (13) and an end disc (17) for closing an end of the through-bore (13) in a non-installed condition of the connector.
