Solution Overview

Problem

Current shoe fastening methods, such as laces, hook and loop fasteners, and buckles, lack customization options and are not easily replaceable when they become defective or discolored, failing to provide aesthetic variety and ease of use for wearers.

Innovation Solution

A shoe fastening system comprising an anchor with a detachable design that engages eyelet holes, a strap assembly with adjustable length and locking mechanisms, and various materials for customization, allowing wearers to easily attach and detach the system for different styles and preferences.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If traditional laces are used, then the shoe can be easily fastened, but the laces cannot be replaced when defective or discolored and offer no customization options

Engineering Contradiction:
Improvecustomization optionsVSAvoidfastening system structure
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The fastening system is divided into separate modular components: anchors that attach to the shoe eyelets, detachable laces, and optional decorative elements. This segmentation allows individual components to be replaced independently, enabling customization and renewal without replacing the entire fastening system.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The anchor design serves multiple functions: it secures the lace to the shoe, provides a attachment point for decorative elements, and enables easy detachment for lace replacement. The universal anchor design can accommodate various lace types and styles, making the system adaptable to different customization preferences.

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

2Ease of repair

If elastic straps with permanent attachment are used, then the shoe fastening is secure, but the straps cannot be removed or replaced when defective

Engineering Contradiction:
Improvereplacement capabilityVSAvoidfastening security
Core Design Contradiction:
Ease of repairVSReliability

Solution Approach 1:

The anchors are pre-installed and permanently attached to the shoe eyelets during shoe manufacturing or retrofitting. This preliminary action ensures secure attachment points remain fixed and reliable, while allowing the detachable laces to be easily replaced without compromising the security of the fastening system.

Inventive Principle:
Principle #10Preliminary action

3Adaptability or versatility

If decorative elements are added to customize the shoe, then aesthetic variety increases, but the fastening system becomes more complex

Engineering Contradiction:
Improveaesthetic customizationVSAvoidfastening mechanism
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

Decorative elements such as charms, beads, or decorative laces are nested within or integrated with the functional lace structure. The decorative components are attached to the detachable laces or anchors, allowing them to be added or removed without affecting the core fastening mechanism, thus maintaining simplicity while enabling customization.

Inventive Principle:
Principle #7Nested doll (Nesting)
