Reusable Twist Tie Post Structure for Multi-Wrap Securing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Reusable twist ties have limited securing capability due to their structural design and inefficient user interaction, restricting their ability to effectively secure objects.
Innovation Solution
A tie post is designed for reusable twist ties, featuring a first end for removable attachment, a longitudinal post for wrapping the tie around, and a second end with a surface to prevent the tie from moving off, with various configurations such as concavity and projection fits, clamshell designs, and cleats, enhancing the tie's securing capacity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If reusable twist ties are tied upon themselves without a tie post, then the device complexity is reduced, but the securing capability is limited
Solution Approach 1:
A tie post is introduced as an intermediary component between the twist tie and the object being secured. The tie post provides a fixed anchor point that the twist tie can wrap around multiple times, significantly enhancing securing capability compared to tying the twist tie upon itself. The tie post includes a body portion with a head and a base, where the base can be attached to the object or integrated into the twist tie structure.
2Reliability
If the tie post prevents the wrapped portion from moving, then the reliability of the securing mechanism is improved, but the ease of operation deteriorates due to increased friction
Solution Approach 1:
The tie post is designed with different local characteristics: the head portion provides a smooth surface that allows easy wrapping and sliding of the twist tie, while the base portion provides friction and mechanical engagement to prevent unwrapping. This local differentiation of properties enables both easy operation during wrapping and high reliability during securing.
3Ease of operation
If the post length is increased to allow multiple wraps, then the securing capability is improved, but the device complexity increases
Solution Approach 1:
The tie post is segmented into distinct functional portions: a head portion for easy wrapping, a base portion for secure attachment, and an intermediate body portion that provides the necessary length for multiple wraps. This segmentation allows each portion to be optimized for its specific function while keeping the overall structure manageable and simple.
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 tie post significantly improves the securing capability of reusable twist ties by allowing multiple wraps and preventing movement, thereby enhancing their structural integrity and usability.
Implementation Method 1
The first portion can have one of a concavity and a projection and the second portion can have the other of the concavity and the projection where the second portion is configured to elastically deform such that the projection mates with the concavity.
Implementation Method 2
The first portion can be configured to elastically deform to fit over the elongated portion of the reusable twist tie.

AI summary
A tie post for use with a reusable twist tie, the tie post including: a first end being configured for removable attachment to the reusable twist tie; a post extending in a longitudinal direction from the first end configured for wrapping an elongated portion of the reusable twist tie around the post; and a second end having a surface for preventing the wrapped elongated portion of the reusable twist tie from moving in the longitudinal direction off of the post. The tie post can also be integrally formed on one of first and second end caps provided on the reusable twist tie.
