Detachable Shoelace Loop Locking Groove for Footwear Tension
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing shoelace length adjustment devices are typically integrated into shoes during manufacturing and cannot be easily attached or detached from shoes that do not originally have them, making it cumbersome to adjust shoelace tension.
Innovation Solution
A detachable lacing apparatus with a shoelace loop and locking groove system that allows for easy attachment and detachment, featuring a length adjuster detachable part with locking grooves and a cylindrical-shaped housing with a bifurcation part for secure fastening to the shoe, enabling customizable and stable shoelace tension adjustment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If shoelace length adjustment devices are integrated into shoes during manufacturing, then the adjustment function is built-in and permanent, but the device cannot be applied to shoes that do not originally have them and cannot be easily attached or detached
Solution Approach 1:
The lacing apparatus is divided into separate components: a detachable housing containing the adjustment mechanism, a locking groove part for attachment, and a winding drum assembly. This segmentation allows the device to be independently attached to and detached from various shoes without being integrated during manufacturing, thereby improving adaptability while keeping attachment simple.
Solution Approach 2:
The detachable housing with standardized locking groove parts is designed to be universally compatible with different shoe types. The same housing can be attached to various shoes that have shoelace holes, making the adjustment device applicable to multiple shoe models without requiring shoe-specific integration, thus enhancing versatility.
2Ease of operation
If traditional shoelaces are used without adjustment devices, then the shoes are simple and easy to put on, but it is very cumbersome to loosen or re-tighten shoelaces every time shoes are put on and taken off
Solution Approach 1:
The winding drum mechanism allows the user to independently adjust the shoelace length by winding or unwinding the drum, which rotates the locking groove part to engage or disengage from the shoe. This self-service adjustment eliminates the need for external tools or complex mechanisms, providing easy tension adjustment while maintaining relatively simple device structure.
Solution Approach 2:
The lacing apparatus incorporates a dynamic adjustment mechanism where the winding drum can rotate to change the effective length of the shoelace. The locking groove part dynamically engages with the shoe at different positions based on the drum's rotation, enabling continuous adjustment of tension rather than fixed positioning, thus improving ease of operation.
3Reliability
If a detachable lacing apparatus is designed with locking groove parts for secure attachment, then the attachment stability is improved, but the device becomes more complex and harder to attach and detach
Solution Approach 1:
The locking groove part acts as an intermediary component that mediates between the detachable housing and the shoe. It provides a standardized interface with grooves that engage with corresponding protrusions on the shoe, ensuring stable attachment while allowing simple snap-on and snap-off operations. This intermediary design achieves both reliability and ease of operation by separating the complex locking mechanism from the attachment interface.
