Offset Leg Binder Structure for Stable Thin-Object Binding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional binding tools face issues with unstable binding, especially when binding thin objects, as the leg portions spread and become inclined, leading to potential deviation and obstruction.
Innovation Solution
A horseshoe-shaped binding tool with leg portions deviated in the front-rear direction, allowing them to pass each other without oblique deformation, maintaining stability and preventing tip spread, even when binding thin objects.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the leg portions are bent inward to bind the object, then the binding function is achieved, but the tips of the leg portions spread and present an obstacle especially when binding thin objects
Solution Approach 1:
The patent applies dimensionality change by deviating the leg portions from each other in the front-rear direction (adding a longitudinal offset dimension) rather than keeping them parallel. This spatial arrangement allows the leg portions to pass each other during bending without their tips spreading laterally, thus resolving the contradiction between achieving binding function and preventing tip spread obstruction.
2Reliability
If the leg portions are deformed obliquely to pass each other, then the binding function is achieved, but the leg portions become inclined resulting in unstable binding and potential deviation
Solution Approach 1:
The patent resolves the alignment stability issue by introducing a front-rear directional deviation between leg portions. This longitudinal offset allows the leg portions to interpass during bending without requiring oblique deformation, maintaining their perpendicular alignment with the binding axis and preventing post-binding deviation and rotation.
Solution Approach 2:
The patent employs asymmetry by positioning the leg portions at different longitudinal positions (front-rear deviation) rather than symmetrically aligned. This asymmetric arrangement enables the leg portions to clear each other during the binding process without oblique deformation, maintaining stable perpendicular alignment and preventing binding tool rotation.
3Reliability
If excessive force is applied to deform the leg portions obliquely, then the binding function is achieved, but the binding requires larger force and may cause instability
Solution Approach 1:
The patent reduces the required binding force by changing the spatial arrangement of leg portions with front-rear deviation. This configuration allows the leg portions to naturally interpass during bending without requiring strong oblique deformation forces, achieving stable binding with reduced force application.

AI summary
A binding tool includes a pair of leg portions and a central portion that is provided between the pair of leg portions. The binding tool is formed in a horseshoe shape and is capable of binding an object to be bound by bending the pair of leg portions inward. The pair of leg portions are arranged to be deviated from each other in a front-rear direction as viewed in a thickness direction.
