Shoelace Binding Device With Elastic Buckle And Segmented Stoppers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing shoelace binding devices are inefficient for tying, untying, separating, and replacing shoelaces due to difficulties in using buckles and center stoppers, which require simultaneous force application and can be cumbersome for adjusting and replacing shoelaces.
Innovation Solution
A shoelace binding device with a center stopper that divides the shoelace into sections for easy separation, side stoppers that secure the shoelaces with a rotatable lever, and a buckle with a flexible elastic arm and guide surfaces for easy engagement and disengagement, allowing for convenient tying, untying, and replacement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a buckle with separable male and female members is used to secure shoelaces, then the shoelace can be tied without a knot, but it becomes difficult to separate the male and female buckle members that are fastened to each other
Solution Approach 1:
The elastic arm provides dynamic flexibility, allowing it to bend toward the guide when force is applied from outside. This enables the buckle to transition from a locked state to an unlocked state through controlled deformation, solving the contradiction between secure fastening and easy separation
Solution Approach 2:
The elastic arm acts as an intermediary element between the guide and the projection. It transmits force while providing compliance, allowing the projection to engage with and disengage from the side hole through controlled bending, thus enabling both secure locking and easy release
2Reliability
If the center stopper fixes both halves of the shoelace in close contact, then the shoelace can be secured, but it becomes difficult to individually pull the ends of the shoelace
Solution Approach 1:
The center stopper is divided into a first section and a second section that are separated by a predetermined distance. This segmentation allows each half of the shoelace to be independently positioned and pulled, while still maintaining overall fixation, thus resolving the contradiction between secure fixing and individual adjustability
3Reliability
If side stoppers fix both ends of the shoelace in a complicated form, then the shoelace can be secured, but it becomes difficult to separate or replace the shoelace for washing
Solution Approach 1:
The side stopper is segmented into a fixing body and a pressing lever that can rotate independently. This allows the pressing lever to be rotated to release the shoelace from the fixing body, enabling easy separation and replacement of the shoelace while maintaining secure fixation during use
Solution Approach 2:
The pressing lever is designed to rotate between a locked position (pressing the shoelace against the fixing body) and an unlocked position (releasing the shoelace). This dynamic movement enables the side stopper to transition between securing and releasing states, facilitating easy shoelace replacement
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
Enables easy and efficient tying and untying of shoelaces, simple separation and replacement, and ensures equal length adjustment, enhancing user convenience by improving the functionality of center stoppers, side stoppers, and buckles.
Implementation Method 1
an elastic arm formed at a second side of a second end of the male buckle body at a predetermined distance from the guide, having flexibility to be bent toward the guide by force from the outside

AI summary
The present invention relates to a shoelace binding device and, more particularly, to a shoelace binding device that is more convenient by allowing shoelaces to be easily tied and untied, simply replaced, and easily pulled. The shoelace binding device includes: a center stopper fixing a first half and a second half of a shoelace at a middle portion of an instep of a shoe; and a buckle holding the first half and the second half of the shoelace at a middle portion of a neck of the shoe. The buckle includes a male buckle member and a female buckle member. The male buckle member has a male buckle body, a guide formed, and an elastic arm. The female buckle member has a female buckle body, a housing, and a side hole formed.
