Hook-Shaped Lace Loop for Non-Destructive Shoe Attachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lace loops in shoes, particularly in mountain boots, are permanently riveted and cannot be easily replaced if damaged, limiting their interchangeability and adjustability.
Innovation Solution
A lace loop design featuring a hook-shaped attachment section that allows non-destructive attachment and detachment from the shoe, combined with a lace guide section that redirects the shoelace, enabling rotational alignment and displacement for optimal fit without the need for rivets or additional joints.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If lace loops are permanently riveted to the shoe, then the connection between lace loop and shoe is strong and stable, but the lace loop cannot be replaced if damaged and requires destructive removal
Solution Approach 1:
The lace loop system is divided into separate components: a lace loop element and a shoe attachment element with a cord or band connecting them. This segmentation allows the lace loop to be detached and replaced without damaging the shoe, while the cord maintains the connection. The lace loop element can be independently removed and replaced if damaged.
Solution Approach 2:
The attachment system transitions from a static permanent riveted connection to a dynamic removable connection using a cord or band. This allows the lace loop to be moved between different attachment positions on the shoe and enables easy replacement by simply detaching the cord from the damaged lace loop and reattaching it to a new one.
2Strength
If lace loops are riveted to the shoe, then the attachment is permanent and secure, but the shoe and lace loop cannot be separated without causing damage
Solution Approach 1:
A cord or band acts as an intermediary element between the lace loop and the shoe. This intermediary transmits the connecting force while allowing the lace loop to be detached from the shoe without direct mechanical fastening that would cause damage. The cord can be easily removed and reattached without harming either the lace loop or the shoe.
3Stability of the object's composition
If conventional lace loops are used with rivets, then the attachment is fixed in position, but the lace loop cannot be adjusted or rotated for optimal alignment
Solution Approach 1:
The cord connection allows the lace loop to be dynamically positioned and rotated relative to the shoe. The lace loop can be attached at different locations along the cord's length and can rotate around the cord axis, enabling optimal alignment with the lace direction while maintaining a secure connection.
4Adaptability or versatility
If additional joints are added to enable rotation, then the lace loop can be aligned, but the device complexity increases
Solution Approach 1:
The attachment function and rotational adjustment function are merged into a single cord connection system. The cord naturally allows rotation and position adjustment without requiring separate joints or hinges. This integration achieves the desired adaptability while keeping the structure simple and avoiding additional complex components.

AI summary
The invention relates to a shoelace loop (10) for guiding a shoelace of a shoe, comprising a shoelace guide section (12) which has a shoelace contact area (14) configured to make contact with the shoelace in order to redirect it when the shoe is laced, and an attachment section (20) by means of which the shoelace loop (10) can be attached to a corresponding shoe, wherein the attachment section (20) is formed on the shoelace loop (10) outside the shoelace guide section (12), wherein the attachment section (20) is essentially hook-shaped so that the shoelace loop (10) can be attached to the shoe and detached from the shoe without damage. The invention further relates to a shoe with such a shoelace loop (10).
