Dual-Sided Cable Tie Teeth for Breakage-Resistant Bundling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Cable ties with teeth on a single side are prone to breakage, have non-uniform thickness, and can loosen due to external forces, leading to unstable bundling.
Innovation Solution
A cable tie design with teeth on both sides of the tie body, where the convex and inner teeth are asymmetrically distributed and overlap partially, combined with locking teeth in the locking head, and an elastic block mechanism to ensure even stress distribution and engagement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If teeth are arranged on a single side of the tie body, then the structure is simple, but the tie body is prone to breakage and tooth breakage occurs
Solution Approach 1:
The patent divides the single row of teeth into two separate rows located on opposite sides of the tie body. These two rows of teeth work together to engage with the locking head, distributing the stress and preventing breakage while maintaining structural simplicity.
Solution Approach 2:
The patent transitions from a single-sided tooth arrangement to a dual-sided arrangement, utilizing the thickness dimension of the tie body to position teeth on both surfaces. This dimensional change allows for better stress distribution and increased strength without significantly complicating the structure.
2Ease of manufacture
If teeth are arranged on a single side of the tie body, then the manufacturing is simple, but the thickness is non-uniform and bundling stability is poor
Solution Approach 1:
The patent segments the tooth arrangement into two independent rows on opposite sides, each row contributing to the overall stability. This segmentation allows for uniform thickness distribution while maintaining ease of manufacture through standard molding processes.
Solution Approach 2:
The patent employs asymmetric tooth designs where the two rows of teeth have different configurations (e.g., different numbers, shapes, or positions) to optimize engagement with the locking head. This asymmetry enhances bundling stability while remaining compatible with simple manufacturing methods.
3Device complexity
If teeth are arranged on a single side of the tie body, then the structure is simple, but unhooking and slipping occur under external force
Solution Approach 1:
The patent divides the locking mechanism into two independent tooth rows that engage with corresponding features in the locking head. This segmentation creates multiple engagement points, preventing unhooking and slipping while keeping the overall structure simple and reliable.
Solution Approach 2:
The patent utilizes the thickness dimension by placing teeth on both sides of the tie body, creating a more robust engagement mechanism. This dimensional approach prevents lateral slipping and unhooking under external forces without significantly increasing structural complexity.

AI summary
Disclosed in the present invention is a cable tie. The cable tie includes a locking head and a tie body, where one end of the tie body is fixedly connected to an outer wall of one end of the locking head close to an extend-in opening, tie teeth are fixedly arranged on outer walls of two sides of the tie body, locking teeth are mounted on inner walls of two sides of the locking head, the locking teeth are matched with the tie teeth, and an extend-out head is integrally formed at one end of the tie body away from the locking head. Engagement on the two sides can prevent the teeth from being reversed when the tie body is pulled. The stress of the locking teeth on the two sides is reduced, resulting in the concentrated force on individual tooth, thereby preventing the teeth from being broken.
