Solution Overview

Problem

Existing pet crates require cumbersome and time-consuming cleaning due to fixed, preformed inserts that do not fit properly or provide stability, and household items like towels move easily, exposing the crate bottom and failing to offer a stable surface for pets.

Innovation Solution

A universal liner with bendable or trimmable sections that can be customized to fit various crate sizes, featuring adjustable walls, non-skid surfaces, and retaining walls to secure bowls, facilitating easy cleaning and pet comfort.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If preformed fixed inserts are used to cover the bottom of the crate, then the crate bottom is covered and provides a surface for the pet, but the cleaning process becomes cumbersome and time-consuming

Engineering Contradiction:
Improvecoverage of crate bottomVSAvoidcleaning time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The liner is divided into modular wall sections that can be independently adjusted or removed. This segmentation allows the liner to be easily adapted to different crate sizes and facilitates quick removal during cleaning, resolving the contradiction between providing reliable crate bottom coverage and reducing cleaning time.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The liner incorporates adjustable and removable wall sections that can be dynamically configured. These sections can be bent to different angles or completely removed based on the specific crate dimensions and cleaning needs, enabling the liner to transition between providing stable coverage and allowing easy access for cleaning.

Inventive Principle:
Principle #15Dynamics

2Reliability

If household items like towels are used to cover the crate bottom, then the crate bottom is covered, but these items move easily and expose the crate bottom

Engineering Contradiction:
Improvecoverage stabilityVSAvoidposition stability
Core Design Contradiction:
ReliabilityVSStability of the object's composition

Solution Approach 1:

The liner utilizes curved or arcuate transition regions between the wall sections and the base. These curved surfaces provide better contact and friction with the crate bottom, preventing the liner from moving or shifting, thus maintaining both coverage reliability and position stability.

Inventive Principle:
Principle #14Spheroidality (Curvature)

Solution Approach 2:

The liner is constructed as a flexible yet stable structure that can conform to the crate bottom surface. This flexibility allows it to adapt to slight variations in crate geometry while maintaining stable positioning, unlike rigid or loose household items.

Inventive Principle:
Principle #30Flexible shells and thin films

3Reliability

If household coverings are used, then the crate bottom is covered, but they do not provide a stable floor surface for the pet

Engineering Contradiction:
Improvecoverage provisionVSAvoidpet comfort
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

Different portions of the liner are designed with different properties: the base section provides a stable, flat walking surface for the pet, while the wall sections provide coverage and containment. This local differentiation ensures both reliable coverage and pet comfort simultaneously.

Inventive Principle:
Principle #3Local quality

4Manufacturing precision

If specifically sized inserts are purchased for a particular crate, then the insert fits that specific crate, but it is difficult to find the right size or results in purchasing an insert that does not properly fit

Engineering Contradiction:
Improvefit precisionVSAvoidcrate size compatibility
Core Design Contradiction:
Manufacturing precisionVSAdaptability or versatility

Solution Approach 1:

The liner is designed as a universal solution that can adapt to multiple crate sizes through its adjustable and removable wall sections. By allowing configuration of wall height and presence, a single liner design can properly fit various crate dimensions, eliminating the need to search for specifically sized inserts.

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

Solution Approach 2:

The liner incorporates dynamic elements such as adjustable wall sections that can be configured to match different crate sizes. This dynamic adaptability allows the same liner to achieve precise fit across multiple crate dimensions, resolving the contradiction between fit precision and crate size versatility.

Inventive Principle:
Principle #15Dynamics
