Cord Attachment System With Tensioner And Fitting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cord attachment systems face difficulties in adjusting tension and connecting/disconnecting components to the cord, leading to potential failure in securing objects together.
Innovation Solution
A cord attachment system featuring a tensioner that maintains cord tension and a fitting for easy connection/disconnection, allowing for adjustable tension by varying the cord's position within the tensioner and using actively moveable elements to secure the cord.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional cord attachment systems are used, then objects can be secured together, but the tension in the cord cannot be adjusted and components cannot be easily connected or disconnected
Solution Approach 1:
The attachment system is divided into separate modular components: a fastener component, a tensioner component, and a cord. Each component can be independently connected or disconnected, enabling easy assembly and disassembly while maintaining secure attachment when assembled.
Solution Approach 2:
The tensioner component includes a movable element that can be shifted between positions to adjust cord tension dynamically. This allows the system to adapt tension levels while maintaining reliable securing of objects.
2Adaptability or versatility
If conventional cord attachment systems are used, then objects can be secured together, but the tension in the cord cannot be adjusted
Solution Approach 1:
The tension adjustment functionality is isolated to a separate tensioner component rather than being integrated into the entire attachment system. This modular approach enables tension adjustability without significantly increasing overall system complexity.
Solution Approach 2:
The tensioner component acts as an intermediary element between the fastener and the cord, providing tension adjustment capability. This intermediary component simplifies the overall design by concentrating the adjustment mechanism in one dedicated element.
3Reliability
If a tensioner is added to adjust cord tension, then cord tension can be maintained, but the complexity of the attachment system increases
Solution Approach 1:
The tensioner component combines multiple functions: it maintains cord tension, provides adjustment capability, and serves as a connection point for the cord. By merging these functions into a single component, the overall number of separate parts is minimized.
Solution Approach 2:
The tensioner component performs multiple roles: it secures the cord, maintains tension, and allows for tension adjustment. This multi-functionality reduces the need for additional specialized components, thereby limiting the increase in system complexity.

AI summary
An attachment system is provided which may include a cord, a fastener coupled to a first portion of the cord, a tensioner coupled to a second portion of the cord, and a first fitting arranged to couple either the fastener or the tensioner to the cord. The tensioner is configured to retain a third portion of the cord to maintain the tension in the cord. An attachment system may include a first working component configured to be coupled to the cord, and a first fitting arranged to couple the first working component to the cord. The first working component may have a cavity configured to receive at least a portion of the first fitting, and the first fitting may have an actively moveable element configured to retain the cord when the first fitting is positioned in the working component cavity.
