Curved Hook Cord Securing Device for Adjustable Tension
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing solutions for securing ropes, bungees, or flat straps to a point lack simplicity and releasability while maintaining security, failing to combine these essential features effectively.
Innovation Solution
A device comprising a cord holding body with a hook portion that curves around the cord, featuring a capture area to securely and removably hold the cord, which can be molded around the cord or include crimps and grooves for enhanced security, allowing for adjustable tension and easy attachment to anchor points.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a securing device uses a simple hook design for easy attachment, then ease of operation is improved, but reliability deteriorates due to potential inadvertent release under tension
Solution Approach 1:
The securing device is divided into distinct functional segments: a cord-holding body that maintains cord position, a hook portion for attachment, and a capture area for securing the cord end. This segmentation allows each component to specialize in one function, achieving both ease of operation (hook for quick attachment) and reliability (capture area preventing release).
Solution Approach 2:
The device incorporates dynamic characteristics through the flexible cord holding body that can deform under tension while maintaining the cord in the capture area. The body adapts its shape to accommodate tension forces, allowing the cord to remain securely captured even when the device is subjected to loading, thus maintaining reliability during operation.
2Reliability
If the cord holding body is molded around the cord for secure holding, then reliability is improved, but device complexity increases due to molding process requirements
Solution Approach 1:
The cord holding body and hook portion are merged into a single integrated component formed by molding. This combining of functions into one piece eliminates the need for separate assembly steps, reducing manufacturing complexity while maintaining the reliability benefits of the molded-around-cord design. The single-mold construction achieves secure cord holding without the added complexity of multiple parts.
3Reliability
If the device includes multiple features (crimps, grooves, capture areas) for enhanced security, then reliability is improved, but device complexity increases
Solution Approach 1:
Multiple security features (crimps, grooves, capture areas) are merged into a single molded body structure. Rather than adding separate components for each feature, the design integrates all security mechanisms into one cohesive piece, achieving enhanced reliability through multiple features while avoiding the complexity of assembling multiple separate elements.
Solution Approach 2:
The device utilizes geometric parameter variations within the molded body to create different functional zones: crimps for friction-based holding, grooves for mechanical interlocking, and capture areas for positional restraint. By varying the geometric parameters of the single molded structure, multiple security mechanisms are achieved without increasing component count or assembly complexity.

AI summary
A device for holding a cord includes a first cord holding area shaped to receive a cord. The device further includes a hook portion interconnected with the first cord holding area, the hook portion curving from a first end of the first cord holding area, around a side of the first cord holding area to a second end of the first cord holding area, opposite the first end.
