Multi-Line Connector with Connection Indication and Locking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing multi-connector devices for connecting fluid and electric lines require high production and operational outlay due to tight manufacturing tolerances and lack of clear connection indication, leading to unreliable connections.
Innovation Solution
A device with a first connection component that moves along a connection axis to connect or disconnect fluid lines, and a second connection component that rotates around the axis to connect or disconnect further lines, providing a clear indication of correct connection through electrical or optical means, and incorporating a locking mechanism for increased reliability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If tight manufacturing tolerances are used for multi-connector connection pieces, then reliable connection is ensured, but production outlay increases significantly
Solution Approach 1:
The patent changes the tolerance parameters from tight to loose by using a two-step connection process with separate connection components. The first component connects fluid lines with loose tolerances, and the second component connects electric lines also with loose tolerances, eliminating the need for tight tolerances while maintaining connection reliability
Solution Approach 2:
The multi-connector is segmented into two separate connection components: a first connection component for fluid lines and a second connection component for electric lines. Each component can be manufactured independently with loose tolerances, avoiding the need for tight tolerances that would be required if both connections were integrated into a single component
2Ease of manufacture
If multi-connector design is simplified, then production outlay decreases, but connection indication is lost
Solution Approach 1:
The patent combines two connection functions into a single multi-connector housing: the first connection component for fluid lines and the second connection component for electric lines. This merging allows both connections to be made simultaneously in a single operation while maintaining the ability to provide connection indication through the second component
3Reliability
If two-step connection process is implemented, then connection reliability improves, but operational complexity increases
Solution Approach 1:
The patent uses a dynamic locking mechanism where the second connection component can be rotated from an initial position to a locked position. This rotational movement dynamically transitions the connection state, providing clear indication of connection status while maintaining operational simplicity through intuitive rotational motion

AI summary
A device for connecting fluid lines and other lines. The device has a first connection component for connecting fluid lines and a second connection component for connecting other lines. The first connection component has a first functional position, in which the first connection component disconnects the two fluid lines from one another, and a second functional position, in which the first connection component connects two fluid lines. The second connection component, in a connection position, connects two other lines and, in a release position, disconnects the two other lines from one another.
