Solution Overview

Problem

Existing aglet protectors do not effectively enclose the aglet of a shoelace, leading to premature wear and damage, and lack an integrated design that enhances the ornamental appearance of the shoelace.

Innovation Solution

A hingedly coupled first and second housing that form a well when closed, with integrated slots to receive and compress the aglet, enhancing retention and aesthetic appeal.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If existing aglet protectors are used, then the aglet is partially covered, but the aglet is not effectively enclosed leading to premature wear and damage

Engineering Contradiction:
Improveprotection effectivenessVSAvoidservice life of shoelace
Core Design Contradiction:
ReliabilityVSDuration of action of stationary object

Solution Approach 1:

The protector is divided into a first housing portion and a second housing portion that can be separately assembled and then closed together to form a complete enclosure around the aglet, ensuring comprehensive protection

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The aglet is nested within the formed well created by the two housing portions, with the shoelace extending through the well, creating a layered protective structure that encloses the vulnerable aglet area

Inventive Principle:
Principle #7Nested doll (Nesting)

2Device complexity

If existing aglet protectors are used, then simple design is maintained, but they lack integrated design that enhances the ornamental appearance of the shoelace

Engineering Contradiction:
Improvedesign integrationVSAvoidornamental appearance
Core Design Contradiction:
Device complexityVSShape

Solution Approach 1:

The protector serves multiple functions simultaneously: it protects the aglet from damage, extends the service life of the shoelace, and enhances its ornamental appearance through the integrated well formation and housing design

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The protective function and ornamental function are merged into a single integrated structure where the housing portions form both a protective enclosure and an aesthetically pleasing component that enhances the shoelace appearance

Inventive Principle:
Principle #5Merging (Combining)

AI summary

A shoelace protector assembly for protecting an aglet on a shoelace includes a first housing that has a first slot integrated into the first housing to insertably receive an aglet on a shoelace. A hinge is hingedly coupled to the first housing, and the hinge is biased into an open position. A second housing is provided, and a second slot is integrated into the second housing. The second housing is coupled to the hinge, such that the second housing is hingedly retained on the first housing. The second housing is positionable in a closed position, having the second slot and the first slot form a well to enclose the aglet of the shoelace.
