Two-Sided Cable Tie with Asymmetric Teeth for Enhanced Tensile Strength
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current cable ties with teeth on a single side suffer from breakage and loosening issues due to uneven thickness and concentrated force on individual teeth, leading to reduced bundling fastness.
Innovation Solution
A cable tie design featuring two tooth-shaped sides with convex and inner teeth that are asymmetrically distributed and partially overlapping, combined with a locking mechanism using a fixed tooth and elastic block, to distribute force evenly and enhance tensile strength.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If teeth are provided on one side of the tie body, then the structure is simple, but the tie body has non-uniform thickness and teeth are easily broken
Solution Approach 1:
The single row of teeth on one side is segmented into two rows of teeth on opposite sides of the tie body. Each row engages with corresponding locking teeth, distributing the engagement force across multiple teeth rather than concentrating it on a single row, thereby preventing tooth breakage while maintaining structural simplicity
Solution Approach 2:
Two rows of teeth on opposite sides work together with corresponding locking teeth to provide combined engagement force. This merging of multiple engagement points creates a more robust locking mechanism that distributes stress evenly, preventing the non-uniform thickness issue while enhancing overall strength
2Device complexity
If teeth are provided on one side of the tie body, then the locking mechanism is simple, but a single row of teeth is subjected to large engagement force causing teeth breakage
Solution Approach 1:
The single engagement point is segmented into multiple engagement points with two rows of teeth on opposite sides. Each row engages with its corresponding locking teeth, dividing the total engagement force into two separate force paths, thereby reducing the force on individual teeth and preventing breakage
Solution Approach 2:
The engagement mechanism transitions from a single-plane engagement to a multi-plane engagement with teeth on opposite sides. This dimensional change allows force to be distributed across different spatial locations, reducing concentrated stress on any single tooth while maintaining a relatively simple locking mechanism
3Device complexity
If teeth are provided on one side of the tie body, then the structure is simple, but the tie body is shaken by external force causing hook-off and slip-off
Solution Approach 1:
The single engagement interface is segmented into two separate engagement interfaces on opposite sides. This segmentation creates multiple independent engagement points that must simultaneously fail for the bundle to loosen, significantly improving reliability while keeping the overall structure simple
Solution Approach 2:
Two engagement interfaces work together to provide combined locking action. The merging of multiple engagement points creates a redundant system where force must overcome both engagement interfaces simultaneously, preventing hook-off and slip-off under external shaking forces while maintaining structural simplicity
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The design prevents tooth breakage and loosening by evenly distributing force across both sides, improving bundling fastness and durability by reducing the force on individual teeth and maintaining uniform thickness.
