Solution Overview

Problem

Current methods for collecting and disposing of dog waste are cumbersome, often resulting in soiled hands, clothing, and multiple used bags, and lack efficiency in sealing and handling excrement, especially in populated areas where regulations require proper disposal.

Innovation Solution

A device featuring a flexible elongate bag and a waste collector with an elongate tube and retraction mechanism that seals the bag into discrete pockets using heating elements or elastic bands, allowing for sanitary and efficient collection and storage of multiple portions of dog waste.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If manual picking method is used, then direct contact with waste occurs, but hygiene and sanitation deteriorate

Engineering Contradiction:

Improveease of waste collectionVSAvoidsoiling of hands and clothing

Core Design Contradiction:

Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The patent introduces a glove-like bag as an intermediary tool between the user's hand and the waste. The bag is donned on the hand like a glove, allowing the user to pick up waste without direct skin contact. The waste is contained within the bag throughout the handling process, and the bag can be inverted to transfer waste to a disposal bag, maintaining hygiene throughout the operation.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Quantity of substance

If multiple disposable bags are carried, then capacity for multiple excrements is sufficient, but portability and convenience deteriorate

Engineering Contradiction:

Improvenumber of bags for multiple excrementsVSAvoidconvenience of carrying multiple bags

Core Design Contradiction:

Quantity of substanceVSEase of operation

Solution Approach 1:

The patent combines multiple individual disposal bags into a single reusable glove-like bag with multiple compartments or a continuous interior space. This allows the user to collect multiple portions of waste during a single walk while carrying only one bag. The bag can be sealed after each use or have separate compartments that can be closed individually, maintaining organization while reducing the number of bags the user must carry.

Inventive Principle:

Principle #5Merging (Combining)

3Productivity

If shovel or rake type devices are used, then waste can be scooped, but precision and cleanliness deteriorate resulting in dropped wastes and dirtied bags

Engineering Contradiction:

Improveefficiency of waste collectionVSAvoidprecision of waste pickup

Core Design Contradiction:

ProductivityVSManufacturing precision

Solution Approach 1:

The patent employs a flexible glove-like bag made of thin film material that can conform to the shape of the waste. This flexible structure allows the user to scoop and contain waste precisely by manipulating the bag with their hand, adapting to irregular shapes and sizes. The flexibility enables complete enclosure of the waste without spilling, unlike rigid shovel or rake devices that may drop waste during transfer.

Inventive Principle:

Principle #30Flexible shells and thin films

4Device complexity

If simple bag inversion method is used, then few devices are needed, but effectiveness for larger excrement portions deteriorates

Engineering Contradiction:

Improvesimplicity of the deviceVSAvoideffectiveness with larger excrement portions

Core Design Contradiction:

Device complexityVSReliability

Solution Approach 1:

The patent incorporates a retractable mechanism that dynamically adjusts the bag's position and shape during the waste collection process. The mechanism can extend to accommodate larger excrement portions and retract to seal the bag properly. This dynamic adjustment ensures reliable containment of waste of varying sizes while maintaining a simple overall device structure that doesn't require complex mechanisms.

Inventive Principle:

Principle #15Dynamics

AI summary

A sanitary excrement removal and bagging system is provided that is capable of collecting multiple, individual portions of dog waste or other excrement and storing them within separate sealed packets of a flexible elongate bag. The excrement removal and bagging system includes a disposable bag and a waste collector including an elongate tube for supporting the disposable bag and a retraction mechanism for drawing the disposable bag into an interior space of the elongate tube. A retraction mechanism can pull the bag into the waste collector. As the bag is pulled into the waste collector, a bag sealing mechanism can close the bag at discrete locations along the length of the bag forming a series of pockets capable of safely and hygienically holding dog waste or other excrements. The bag sealing member can include heating elements for heating and welding the bag to seal the pockets.
