Rotatable Jaw Cord Coupling System for Knotless Joining
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for binding cords together, such as knot tying, are time-consuming and inefficient, especially when cords of fixed length are required for applications exceeding the cord's length, necessitating the use of multiple cords and complex knotting techniques.
Innovation Solution
A cord coupling system featuring a housing with rotatable jaws and channels equipped with angled teeth and a spring mechanism, allowing for easy attachment and detachment of cords by rotating the jaws to secure the cord in place, creating a fixed length without the need for knots.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If knot tying is used to bind cords together, then cords can be joined to achieve required lengths, but it takes substantial time to tie and untie the knot
Solution Approach 1:
A coupling device is introduced as an intermediary mechanism between two cords. The device includes a body with a first channel for receiving a first cord and a second channel for receiving a second cord, with jaws that can be rotated to secure or release the cords. This intermediary device eliminates the need for direct knot tying while providing a controlled mechanism for joining and separating cords quickly and securely.
2Length of moving object
If multiple cords are used to achieve greater length, then the required length can be obtained, but the complexity of binding multiple cords increases
Solution Approach 1:
The coupling device is designed with universal functionality to handle multiple cords through standardized channels and jaws. The body can accommodate different cord configurations (single cord through both channels, multiple cords in separate channels) using the same basic mechanism of rotatable jaws with teeth. This multi-functional design simplifies the binding process regardless of the number or type of cords being joined.
3Reliability
If conventional knotting techniques are used, then cords can be bound securely, but the process is time-consuming and inefficient
Solution Approach 1:
The coupling device employs dynamic rotatable jaws that can be easily rotated between locked and unlocked positions. The jaws include teeth that engage with the cords to provide secure binding when rotated to the locked position, and can be quickly released by rotating to the unlocked position. This dynamic mechanism maintains reliable cord security while dramatically improving binding and unbinding efficiency compared to static knot structures.

AI summary
A cord coupling system is provided. The cord coupling system includes a housing with a first half, a second half, a top surface, an opposed bottom surface, a front surface, and a rear surface. The housing includes a set of channels. The set of channels have a pair of rotatable jaws partially disposed therein and a pair of gates are adjacent to the pair of rotatable jaws. The pair of rotatable jaws and the pair of gates rotate between a first position and a second position.
