Binding Assembly with Segmented Tie Fastening Holders
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional binding assemblies, such as shoe ties, are difficult for children and disabled individuals to tighten or release efficiently, often leading to inconvenient loosening during use.
Innovation Solution
A binding assembly comprising a binding frame with a base, pivotal ears, pressing member, tie fastening holders, and separating members, which utilizes a pulling tie and tightening tie to facilitate easy and rapid tightening and release through a unique configuration of holes and segments, allowing for secure binding and effortless adjustment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a conventional bow tie is used, then the binding function is achieved, but it is difficult for children and disabled persons to tie and easily released
Solution Approach 1:
The tie fastening holder is divided into multiple functional segments: a body portion with a hole for the tightening tie, a pressing portion with a pressing hole for the pulling tie, and a pivotal ear for rotation. This segmentation allows independent control of tightening and releasing functions, making operation easier while maintaining security.
Solution Approach 2:
The tie fastening holder is designed to pivot relative to the binding frame through the pivotal ear, transforming from a static structure to a dynamic one. This dynamic capability allows the holder to rotate and lock the tightening tie in place, providing secure binding while enabling easy release by manipulating the pulling tie.
2Device complexity
If a simple tie structure is used, then the device complexity is reduced, but the tightening and releasing operation becomes difficult
Solution Approach 1:
The pressing member acts as an intermediary between the pulling tie and the tie fastening holder. When the pulling tie is pulled, the pressing member presses against the tie fastening holder, causing it to pivot and lock the tightening tie. This intermediary mechanism translates simple pulling motion into effective tightening action.
Solution Approach 2:
The tie fastening holder automatically locks itself when the tightening tie is pulled through it. The pivotal motion causes the holder to engage with the tightening tie, creating a self-securing mechanism that requires no additional fastening steps, thus simplifying operation while maintaining security.
3Reliability
If a conventional binding method is used, then the binding function is achieved, but the releasing process is inconvenient and time-consuming
Solution Approach 1:
The releasing function is extracted and assigned to a specific component: the pulling tie. By dedicating one tie to tightening (through the pressing mechanism) and another to releasing, the system allows rapid release by simply pulling the designated pulling tie, which triggers the pivotal motion to unlock the tightening tie.
Solution Approach 2:
The pressing member serves as an intermediary that connects the pulling tie's motion to the tie fastening holder's pivotal motion. When the pulling tie is pulled, the pressing member translates this motion into rotation of the holder, which automatically releases the tightening tie, enabling quick and easy release without manual manipulation of the tightened knot.

AI summary
A binding assembly has a binding frame (10), a pulling tie (20) and a tightening tie (30). The binding frame (10) has a base (11), a pressing member (12), two tie fastening holders (13) and two separating members (14). The tie fastening holders (13) are connected pivotally to the base (11) and each has a pulling tie hole (132) and a tightening tie hole (131). Each separating member (14) divides the corresponding tightening tie hole (131) into a first hole segment (1311) and a second hole segment (1312). The pulling tie (20) is compressed by the pressing member (12) and has two ends mounted respectively through the pulling tie holes (132). The tightening tie (30) has two ends mounted respectively through the first hole segments (1311), mounted respectively over the separating members (14) and mounted respectively through the second hole segments (1312).
