Solution Overview

Problem

Traditional methods for pet waste collection, such as plastic bags and scoopers, face challenges in grip and maneuverability, especially on uneven surfaces, making the process inefficient and less hygienic.

Innovation Solution

A waste collection bag designed with internal compartments for finger placement, enhanced by sealed areas extending from the closed edge, improving grip and control, and optionally featuring a drawstring or handles for secure sealing and carrying.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If traditional plastic bags are used for pet waste collection, then the bags are readily available and inexpensive, but they present challenges in grip and maneuverability making the process cumbersome

Engineering Contradiction:

Improveavailability and costVSAvoidgrip and maneuverability

Core Design Contradiction:

Ease of manufactureVSEase of operation

Solution Approach 1:

The bag is divided into multiple finger compartments (first, second, third, and fourth compartments) that separately accommodate each finger. This segmentation allows each finger to independently grip and manipulate the bag, significantly improving grip precision and maneuverability while maintaining the simple plastic bag structure and low cost

Inventive Principle:

Principle #1Segmentation

2Ease of operation

If scoopers are used for waste collection, then hands-off approach is achieved, but they do not work effectively on uneven surfaces or in grassy areas

Engineering Contradiction:

Improvehands-off collectionVSAvoideffectiveness on uneven surfaces

Core Design Contradiction:

Ease of operationVSAdaptability or versatility

Solution Approach 1:

The bag serves as an intermediary tool between the user and the waste. By inserting fingers into the compartments, the user can manipulate the bag to collect waste from various surfaces including uneven ground and grassy areas, while maintaining hygiene through direct finger insertion rather than hand contact with waste

Inventive Principle:

Principle #24Intermediary (Mediator)

3Device complexity

If traditional bags are used, then simplicity is maintained, but direct contact with waste occurs reducing hygiene

Engineering Contradiction:

ImprovesimplicityVSAvoiddirect contact with waste

Core Design Contradiction:

Device complexityVSObject-affected harmful factors

Solution Approach 1:

The bag structure segments the user's fingers into separate compartments, allowing precise finger insertion for waste collection while maintaining overall bag simplicity. This segmented design provides better control and hygiene by enabling targeted finger placement without requiring complex mechanisms

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The bag is designed as a simple, inexpensive, single-use disposable item. After use, the entire bag including the waste is discarded, eliminating the need for cleaning and reducing hygiene concerns. The simplicity of the disposable design is maintained while improving usability through the finger compartment feature

Inventive Principle:

Principle #27Cheap short-living objects (Disposable)

AI summary

Disclosed are example embodiments of a waste collection bag. The waste collection bag includes a body with an opening at one end. The waste collection bag also includes a plurality of compartments formed within said body. Each compartment is sized and shaped to receive a user's finger(s), thereby defining separate finger areas within the bag to facilitate gripping and manipulation of the bag. The compartments are formed by a sealed area extending partway up from a closed edge opposite the opening.
