Solution Overview

Problem

Current shoe tying devices are complex, difficult to remove, and reveal their use, making them unsuitable for children, disabled persons, and elderly individuals who struggle with dexterity or learning to tie shoelaces.

Innovation Solution

A two-piece lockable shoe tying device with a female and male member, featuring engagement sections, cut-out portions, and cantilever pillars for holding lace loops, allowing easy use and removal, and designed for ease of use with rounded corners and concave cut-outs.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If current shoe tying devices are used, then shoe laces can be tied, but the devices are complex and difficult to remove

Engineering Contradiction:
Improveease of removalVSAvoiddevice complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The device is divided into two separate members: a first member with engagement sections and a second member with corresponding engagement features. These members can be easily separated from each other and from the shoe, simplifying removal while maintaining functional complexity only where needed for operation.

Inventive Principle:
Principle #1Segmentation

2Ease of operation

If current shoe tying devices are used, then shoe laces can be tied, but the devices reveal their use making users obvious

Engineering Contradiction:
Improvediscreteness of useVSAvoiddevice structure
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The device is designed to be completely removable from the shoe after use. Both the first and second members can be detached from the shoe and from each other, allowing the user to remove all traces of the device after tying the laces, thus maintaining discretion.

Inventive Principle:
Principle #2Taking out (Extraction)

3Ease of operation

If current shoe tying devices are used, then shoe laces can be tied, but the devices are intimidating and difficult to use

Engineering Contradiction:
Improveease of useVSAvoidnumber of apertures and movements
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The device incorporates features that guide the user through the tying process automatically. The engagement sections and cut-out portions are positioned to naturally guide lace placement and knot formation, reducing the need for complex manual maneuvers or multiple apertures.

Inventive Principle:
Principle #25Self-service

AI summary

A shoe tying device that includes a female member having a first female member end, a second female member end, at least one female engagement section, and two cut-out portions. The shoe tying device further includes a male member having a male member top face, a first male member end, and a second male member end. The male member includes two pillars that project from the male member top face, at least one male engagement member that extends from the first male member end of the male member, and two cut-out portions that extend from the first male member end towards the second male member end. The at least one female engagement section and the at least one male engagement section selectively engageable each other creating an opening from the alignment of the cut-out portions of the of the female member and the cut-out portions of the male member.
