Pull-Cord Clamp Coupling for Compact Push-Pull Connector Release
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing push-pull connectors with pull straps require significant storage space due to their protruding design, and accessing the release mechanism can be difficult due to space constraints.
Innovation Solution
A pull-cord coupling with a hinged clamp and a pull cord that is attached to the connector's outer contour, allowing for a compact design and easy access to the release mechanism by pulling the pull cord.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a pull strap is attached to the movable release mechanism of the push-pull connector, then the connector can be easily disconnected by pulling the strap, but the storage space requirement increases significantly due to the protruding design
Solution Approach 1:
The pull strap coupling device is designed to be nested around the connector body. The clamp arms wrap around and engage with the connector housing, allowing the pull strap to be stored in a compact manner against the connector rather than protruding outward, thus reducing storage space while maintaining ease of operation
Solution Approach 2:
The pull strap coupling transitions from a linear protruding configuration to a three-dimensional arrangement where the clamp arms wrap around the connector in multiple directions. This dimensional change allows the pull strap to be accessed easily while occupying minimal storage space by utilizing the space around the connector body
2Ease of operation
If the release mechanism is made accessible for easy operation, then the connector can be easily disconnected, but the connector design becomes more complex
Solution Approach 1:
The pull strap coupling acts as an intermediary between the user and the release mechanism. Instead of directly exposing or modifying the release mechanism, the coupling transmits the pulling force through the clamp arms to the release mechanism, simplifying the overall design while maintaining ease of operation
Solution Approach 2:
The release mechanism is segmented into distinct functional components: the pull strap for user interaction, the clamp arms for force transmission, and the internal release mechanism for actual disconnection. This segmentation allows each component to be optimized independently, reducing overall complexity while improving accessibility

AI summary
A pull-cord coupling (1) for a connector (100) with a push-pull locking mechanism comprises a pull cord (10) and a coupling clamp (20). The pull cord (10) is attached to and/or attachable to the coupling clamp (20) at least at one attachment point. The coupling clamp (20) is attached to and/or attachable to an outer contour (110) of the connector (100) in a form-fit and/or force-fit manner.
