Multi-Cord Connector With Pierced Membrane Sealing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cord connectors struggle to efficiently manage and connect multiple cords, often requiring additional sealing mechanisms to maintain a liquid-tight connection.
Innovation Solution
A cord connector design featuring a first and second body with bushing passages sealed by membranes, allowing for the piercing of membranes to route cords through, and a clamping ring to secure the cords, eliminating the need for secondary sealing structures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional cord connectors are used to connect multiple cords, then cord connection is achieved, but additional sealing mechanisms are required to maintain liquid-tight connection
Solution Approach 1:
The patent combines the sealing function with the cord connection structure by integrating membranes directly into the bushings. The membranes are positioned within the bushing passages and seal against the cord surfaces, eliminating the need for separate sealing mechanisms. This integration merges two previously distinct functions (connection and sealing) into a single unified structure.
Solution Approach 2:
The membranes are designed to be self-sealing by utilizing the cord itself as the sealing surface. When the cord is inserted through the bushing passage, the membrane naturally conforms to the cord surface and creates a seal without requiring additional sealing components. The system uses the cord's own presence to activate the sealing function.
2Reliability
If membranes are used to seal bushing passages, then liquid-tight seal is maintained, but cord insertion requires membrane piercing
Solution Approach 1:
The membranes are pre-positioned within the bushing passages in a sealed state before cord insertion. The system is prepared in advance with the sealing mechanism in place, and the cord insertion process simply requires piercing the pre-positioned membrane rather than installing sealing components during installation.
3Ease of operation
If multiple cords are routed through separate passages, then cord management is improved, but device complexity increases
Solution Approach 1:
The bushing structure serves multiple functions simultaneously: it provides structural support for cord routing, contains integrated membranes for sealing, and creates separate passages for multiple cords. This multi-functional design eliminates the need for separate sealing mechanisms for each passage, reducing overall device complexity while maintaining effective cord management.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The design effectively manages multiple cords by allowing for easy insertion and secure retention, while maintaining a liquid-tight seal without the need for additional sealing mechanisms.
Implementation Method 1
Each bushing passage is sealed with a membrane. The membrane is disposed within the bushing passage between the first end and the second end.
Implementation Method 2
The membrane is configured to be pierced to open the bushing passage.

AI summary
A cord connector may be used for holding one or more cords. The cord connector includes a first body, a second body, and a bushing. The second body is removably coupled to the first body. The bushing is disposed between the first body and the second body. The bushing includes at least two bushing passages extending from a first end of the bushing toward a second end of the bushing. Each bushing passage is sealed with a membrane. The membrane is disposed within the bushing passage between the first end and the second end. The membrane is configured to be pierced to open the bushing passage.
