Solution Overview

Problem

Conventional pet urine collection systems, such as litter boxes and house training methods, face issues with non-disposable components and frequent replacement of odor-absorbing pellets, as well as accidents occurring inside the house during training.

Innovation Solution

A multi-layered pee collection pad with an integrated drawstring for easy disposal, featuring an absorbent top layer and a leak-proof bottom layer, along with a vertical capture device for efficient urine and waste collection.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If litter boxes with odor-absorbing pellets are used, then urine collection is achieved, but the system requires frequent replacement of pellets and is not disposable

Engineering Contradiction:

Improveurine collection effectivenessVSAvoiddisposal convenience

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The patent implements a disposable pee pad that can be used once and then discarded entirely, eliminating the need to replace odor-absorbing pellets in a permanent litter box. The entire collection system becomes a single-use item that maintains reliability while solving the disposal convenience problem.

Inventive Principle:

Principle #27Cheap short-living objects (Disposable)

Solution Approach 2:

The pee pad is divided into multiple functional layers: an absorbent top layer for urine capture, an odor-absorbing middle layer, and a leak-proof bottom layer. This segmentation allows each layer to perform its specific function optimally while the entire structure remains disposable.

Inventive Principle:

Principle #1Segmentation

2Adaptability or versatility

If house training methods are used, then pets learn to relieve themselves outside, but accidents still occur inside the house

Engineering Contradiction:

Improvetraining effectivenessVSAvoidindoor accidents

Core Design Contradiction:

Adaptability or versatilityVSObject-affected harmful factors

Solution Approach 1:

The disposable pee pad provides a backup containment system that prevents indoor accidents from becoming problems. Even during the house training process, the pad absorbs and contains any accidental urination, protecting floors and furniture while the pet learns proper bathroom habits.

Inventive Principle:

Principle #11Beforehand cushioning (Prior cushioning)

3Ease of operation

If disposable pee pads are used, then disposal convenience is improved, but effective containment and odor absorption may be compromised

Engineering Contradiction:

Improvedisposal convenienceVSAvoidodor absorption effectiveness

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The pee pad uses composite material construction with multiple layers serving different functions: an absorbent layer for urine, an odor-absorbing layer (possibly containing activated carbon or similar materials), and a leak-proof barrier layer. This composite structure ensures that the disposable pad matches or exceeds the performance of permanent systems.

Inventive Principle:

Principle #40Composite materials

AI summary

A pet waste collection system includes a multi-layered pad configured to lay flat on a surface and having a top layer to be an absorbent layer; and a ground layer to be a leak-proof layer; a drawstring integrated into the ground layer; and pull tabs attached to the drawstring; a user may pull the plurality of pull tabs in an opposing direction causing the drawstring to tighten to collect pet waste within the multi-layered pad.
