Solution Overview

Problem

Existing protective footwear for domestic animal paws is inconvenient to apply and remove, uncomfortable, and provides inadequate protection against high temperatures and foreign body lacerations.

Innovation Solution

A protective insole with adhesive layers on the upper face, allowing easy and secure attachment to the paw's bearings, and a non-adhesive third portion to prevent hair attachment, ensuring comfortable wear and easy removal.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Object-affected harmful factors

If protective footwear is designed to cover the entire paw, then protection against high temperatures and lacerations is improved, but application and removal become difficult and time-consuming

Engineering Contradiction:
Improveprotection against high temperatures and lacerationsVSAvoidapplication and removal convenience
Core Design Contradiction:
Object-affected harmful factorsVSEase of operation

Solution Approach 1:

The insole is divided into three distinct portions: a first adhesive portion for the major bearing, a second adhesive portion for the minor bearings, and a third non-adhesive portion for the hair-bearing area. This segmentation allows the protective covering to be applied only where needed (on the bearings) while avoiding the hair area, making application and removal easy and quick.

Inventive Principle:
Principle #1Segmentation

2Reliability

If adhesive is applied to the entire insole surface, then protection and adhesion to bearings are improved, but hair attachment causes annoyance during removal

Engineering Contradiction:
Improveadhesion to bearingsVSAvoidremoval comfort
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The insole has different surface properties in different areas: the first and second portions have adhesive properties for reliable attachment to the bearings, while the third portion is specifically made non-adhesive to prevent hair attachment. This local differentiation of properties ensures both reliable protection and comfortable removal.

Inventive Principle:
Principle #3Local quality

3Ease of operation

If the insole is made thin and flexible, then comfort and ease of application are improved, but protection against high temperatures and lacerations is reduced

Engineering Contradiction:
Improvecomfort and ease of applicationVSAvoidprotection effectiveness
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The insole is designed as a thin, flexible protective layer that can be easily applied to the paw contours. Despite its thinness, it provides effective protection against high temperatures and lacerations by forming a continuous barrier over the sensitive bearing areas while maintaining flexibility for animal movement and comfort.

Inventive Principle:
Principle #30Flexible shells and thin films
