Solution Overview

Problem

Studded athletic shoes' nails wear out quickly when used on surfaces other than tracks, leading to reduced performance and the need for specialized tools to change nails, which can cause discomfort and musculoskeletal issues due to altered walking patterns.

Innovation Solution

A protective shell with a cushioned sole and adjustable clamping device that fits over studded shoes, protecting the nails and allowing natural walking by distributing the pressure, adaptable to various nail configurations and shoe sizes.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Duration of action of moving object

If athletes wear studded shoes on non-track surfaces, then they can move between locations, but the studs wear out quickly and lose effectiveness

Engineering Contradiction:
Improvestud effectivenessVSAvoidsurface contact wear
Core Design Contradiction:
Duration of action of moving objectVSObject-affected harmful factors

Solution Approach 1:

The patent introduces a protective cover as an intermediary element between the studs and non-track surfaces. This cover protects the studs from direct contact with hard surfaces like concrete and tiles, preventing wear and maintaining stud effectiveness when athletes need to move between locations.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The protective cover is designed as a separate, removable component that can be attached to and removed from the studded shoes. This segmentation allows the studs to remain effective for track use while being protected during non-track activities, resolving the contradiction between mobility and stud preservation.

Inventive Principle:
Principle #1Segmentation

2Reliability

If athletes use specialized wrenches to change studs, then they can maintain stud sharpness, but they experience discomfort and musculoskeletal issues due to altered walking patterns

Engineering Contradiction:
Improvestud sharpness maintenanceVSAvoidwalking comfort
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The protective cover serves a dual function: it protects the studs during non-track activities and can be easily removed or adjusted by the athlete themselves without requiring specialized tools or assistance. This self-service capability eliminates the need for wrenches and maintains walking comfort while preserving stud sharpness through protection rather than frequent adjustment.

Inventive Principle:
Principle #25Self-service

3Reliability

If athletes adopt a penguin walk to protect studs, then they avoid damaging the nails, but they experience musculoskeletal strain and discomfort

Engineering Contradiction:
Improvestud protectionVSAvoidwalking naturalness
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The protective cover acts as a mediator that allows athletes to walk naturally on non-track surfaces without damaging the studs. Instead of altering their gait, athletes can wear the cover during activities like using restrooms or walking on concrete, thereby maintaining both walking naturalness and stud protection.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The protective cover is designed to be dynamically adaptable - it can be easily put on and taken off depending on the activity. This dynamic approach allows athletes to maintain natural walking patterns when needed while providing stud protection during vulnerable activities, eliminating the need for continuous altered gait patterns.

Inventive Principle:
Principle #15Dynamics
