Solution Overview

Problem

Existing pet litter systems are cumbersome and difficult to manage due to the need for frequent cleaning and disposal of litter, which can be unpleasant and time-consuming.

Innovation Solution

A disposable litter device comprising a flexible liner layer with closure means, such as a drawstring, and a removable litter enclosure layer, designed for easy installation and removal from a litter box, allowing for simple disposal of soiled litter while retaining the liner for reuse.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If traditional litter systems are used, then litter can be retained in the litter box, but frequent cleaning and disposal becomes cumbersome and time-consuming

Engineering Contradiction:

Improveease of litter managementVSAvoidtime for cleaning and disposal

Core Design Contradiction:

Ease of operationVSLoss of time

Solution Approach 1:

The litter system is segmented into a reusable litter box and a disposable litter device. The disposable litter device contains the litter within a pre-formed enclosure structure that can be easily removed and replaced as a single unit, eliminating the need for manual cleaning and disposal of loose litter

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The litter is pre-loaded into a disposable enclosure device before use. This preliminary preparation allows the user to simply replace the entire litter device when needed, rather than performing cleaning and disposal tasks during use

Inventive Principle:

Principle #10Preliminary action

2Ease of operation

If disposable litter devices are used, then litter disposal becomes easier, but the device complexity increases due to additional components like closure layers and opening means

Engineering Contradiction:

Improveease of litter disposalVSAvoidstructure complexity

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The disposable litter device is segmented into distinct functional layers: a closure layer that seals the litter during storage and transport, and a liner layer that contains the litter during use. The closure layer can be removed to expose the litter, providing a simple two-step operation that reduces perceived complexity

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Instead of having an open litter container that needs to be filled and sealed, the invention inverts the approach by providing a pre-sealed closure layer that is removed to expose the litter. This reversal simplifies the user interaction from multiple steps (filling, sealing, opening) to a single step (removing closure layer)

Inventive Principle:

Principle #13The other way round (Inversion)
