Solution Overview

Problem

Athletic shoes lack waterproof protection and warmth during inclement weather, and existing protective overshoes are not easily removable or adjustable, impacting performance and comfort.

Innovation Solution

A waterproof protective overshoe with a body and sole portion, featuring zippers or other opening and tightening mechanisms for quick donning and doffing, along with a removable sole insert that can incorporate heating or cooling devices for added warmth and insulation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Weight of moving object

If athletic shoes are made lightweight with thinner soles and mesh materials, then weight is reduced and performance is improved, but waterproof protection and warmth are compromised

Engineering Contradiction:
Improveshoe weightVSAvoidwater and cold exposure
Core Design Contradiction:
Weight of moving objectVSObject-affected harmful factors

Solution Approach 1:

The overshoe is divided into a removable sole insert and an upper body portion, allowing independent replacement and customization. The sole insert can be removed for cleaning or replacement while the upper remains, and vice versa, enabling targeted optimization of weight and protection features.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The overshoe acts as an intermediary protective layer between the foot/shoe and the harsh outdoor environment. It provides waterproof and thermal protection without requiring modification to the athletic shoe itself, thus preserving the shoe's lightweight performance characteristics while adding environmental protection.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Object-affected harmful factors

If conventional overshoes are designed for protection, then waterproof coverage is provided, but ease of quick donning and doffing is reduced

Engineering Contradiction:
Improveweather protectionVSAvoidquick donning and doffing
Core Design Contradiction:
Object-affected harmful factorsVSEase of operation

Solution Approach 1:

The overshoe incorporates dynamic fastening systems including zippers and adjustable straps that can be quickly engaged and disengaged. The elastic materials allow the overshoe to dynamically adapt to the shoe shape during donning, then lock into place when fastened, providing both ease of use and secure protection.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The removable sole insert separates the complex fastening requirements from the protective upper portion. The upper can be quickly donned over the shoe, while the sole insert can be separately attached or removed as needed, simplifying the overall donning process while maintaining comprehensive protection.

Inventive Principle:
Principle #1Segmentation

3Object-affected harmful factors

If protective overshoes are worn over athletic shoes, then waterproof protection is achieved, but performance properties of the shoe are negatively impacted

Engineering Contradiction:
Improvewaterproof protectionVSAvoidathletic performance
Core Design Contradiction:
Object-affected harmful factorsVSAdaptability or versatility

Solution Approach 1:

The overshoe upper is constructed from flexible, thin waterproof or water-resistant materials that conform to the shape of the athletic shoe without adding significant bulk or rigidity. This maintains the shoe's natural flex and performance characteristics while providing environmental protection.

Inventive Principle:
Principle #30Flexible shells and thin films

Solution Approach 2:

The adjustable straps and elastic materials allow the overshoe to dynamically adapt to different shoe shapes and sizes, ensuring a snug fit that doesn't interfere with athletic movement. The fastening system can be adjusted to accommodate various performance needs while maintaining protection.

Inventive Principle:
Principle #15Dynamics

4Object-affected harmful factors

If overshoes provide protection from weather elements, then waterproof coverage is achieved, but warming mechanism and shoe drying capability are absent

Engineering Contradiction:
Improveweather protectionVSAvoidfoot warmth and shoe drying
Core Design Contradiction:
Object-affected harmful factorsVSTemperature

Solution Approach 1:

The overshoe serves multiple functions: waterproof protection, thermal insulation, and active heating. The heating elements integrated into the sole insert and upper allow the overshoe to not only protect from cold and wet conditions but actively warm the foot and dry the athletic shoe, combining protective and therapeutic functions in one device.

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