Adjustable Bungee Cord Lock with Segmented Frame
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bungee cord hooks have a predetermined length, making them inflexible and requiring replacement if the length is not suitable, leading to inefficiencies in securing articles.
Innovation Solution
A bungee cord lock with a frame featuring interconnecting members, channels, and locking tabs that allow for adjustable indeterminate length of bungee cord, enabling secure attachment and adjustment of bungee cord locks along the cord.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a predetermined length bungee cord is used with fixed hooks, then the structure is simple and easy to manufacture, but the adaptability is poor and the cord cannot be adjusted to different lengths
Solution Approach 1:
The bungee cord system is segmented into a cord body and separate locking mechanisms that can be positioned independently along the cord length, enabling adjustable length configuration while maintaining manufacturing simplicity
Solution Approach 2:
The locking mechanism incorporates movable components that allow dynamic adjustment of the bungee cord length, transitioning from a fixed predetermined length to an adjustable configuration through simple structural elements
2Loss of substance
If the bungee cord length is predetermined, then manufacturing is simple, but loss of substance occurs when the cord length is not suitable and must be scrapped
Solution Approach 1:
The adjustable locking mechanism allows the bungee cord length to be dynamically modified after manufacturing, eliminating the need to scrap cords due to length mismatches while maintaining simple production processes
Solution Approach 2:
The system enables parameter changes in cord length through adjustable locks rather than manufacturing different fixed-length cords, reducing material waste without complicating the manufacturing process
3Loss of time
If the bungee cord length is predetermined, then the structure is simple, but loss of time occurs when replacement is needed due to incorrect length
Solution Approach 1:
The dynamic adjustment capability allows users to modify cord length in situ without replacement, saving time while maintaining structural simplicity through straightforward locking mechanisms
Solution Approach 2:
The adjustable locking system enables self-service length modification by the user without requiring replacement of the entire cord or complex adjustment mechanisms
