Solution Overview

Problem

Pet training pads struggle to prevent pet urine and feces from flowing over their edges, leading to unwanted spills on adjacent surfaces.

Innovation Solution

A pet training pad design featuring a central region with a higher concentration of absorbent material and sloping channels that direct fluid flow towards this area, ensuring efficient absorption of waste fluids.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a conventional pet training pad with uniform absorbent material distribution is used, then the pad provides basic absorption coverage, but urine and feces flow over the edges onto adjacent surfaces

Engineering Contradiction:

Improvecontainment of pet wasteVSAvoidurine flowing over edges

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent applies local quality by creating a central region with higher absorbent material concentration specifically where pet waste is most likely to be deposited. This non-uniform distribution concentrates absorption capacity at the critical location, preventing urine flow to edges while maintaining overall pad functionality.

Inventive Principle:

Principle #3Local quality

Solution Approach 2:

The patent implements curvature by forming the top surface with a downward slope toward the central region, creating a contour that naturally directs fluid flow via gravity. This curved surface geometry channels urine and feces toward the high-absorbency center, preventing edge overflow.

Inventive Principle:

Principle #14Spheroidality (Curvature)

2Quantity of substance

If absorbent material is distributed uniformly across the pad, then manufacturing is simple, but absorption capacity at the center where waste is deposited is insufficient

Engineering Contradiction:

Improveabsorption capacity at centerVSAvoidabsorbent material distribution structure

Core Design Contradiction:

Quantity of substanceVSDevice complexity

Solution Approach 1:

The patent concentrates absorbent material in the central region where pet waste is most likely to be deposited, creating a high-absorbency zone that matches the actual usage pattern. This local concentration increases effective absorption capacity without requiring excessive material throughout the entire pad.

Inventive Principle:

Principle #3Local quality

Solution Approach 2:

The contoured top surface with downward slope toward the center creates natural fluid channels that guide urine and feces to the high-absorbency central region. This geometric design enhances material utilization by directing waste to where absorption capacity is greatest.

Inventive Principle:

Principle #14Spheroidality (Curvature)
