Pet Waste Disposal Kit with Biodegradable Gloves and Chemical Treatment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for pet waste disposal are unsanitary, exposing handlers to biological hazards and failing to treat pathogen content, posing risks to public health.
Innovation Solution
A pet waste disposal kit with impermeable gloves, deodorizing and disinfecting waste bags, and a secondary container for safe handling and storage, utilizing a disinfecting-deodorizing mixture with high alkalinity and desiccants to inhibit bacterial growth and repel insects, along with antiseptic hand wipes for sanitation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual handling of waste collection bags is used, then simplicity of operation is maintained, but exposure to biological hazards and unsanitary conditions increases
Solution Approach 1:
The patent introduces an intermediary system consisting of impermeable gloves and a secondary container that acts as a barrier between the handler and the waste. The gloves provide direct hand protection, while the secondary container serves as an intermediate storage that eliminates the need for handlers to directly handle sealed waste bags, thus resolving the contradiction between operational simplicity and hazard exposure.
Solution Approach 2:
The patent employs disposable impermeable gloves that are used once and then discarded with the waste. This disposable approach ensures that handlers are never exposed to biological hazards since the gloves are replaced after each use, maintaining simplicity while eliminating recurring exposure risks.
2Reliability
If waste collection bags contain disinfecting chemicals, then pathogen treatment is improved, but bag complexity and manufacturing difficulty increase
Solution Approach 1:
The patent applies parameter changes by incorporating chemical substances (disinfectants, deodorizers, desiccants) into the waste collection bag material or as coatings. This transforms the bag from a simple physical container to a chemically active treatment system, achieving reliable pathogen treatment while maintaining relatively simple manufacturing through coating or mixing processes.
Solution Approach 2:
The waste collection bag is constructed as a composite material system combining impermeable plastic with embedded or coated disinfecting chemicals, deodorizers, and desiccants. This composite approach achieves comprehensive pathogen treatment and waste management functions while maintaining manufacturability through integrated material production processes.
3Object-affected harmful factors
If impermeable gloves are worn during waste handling, then protection from pathogens is improved, but comfort and dexterity of the handler deteriorate
Solution Approach 1:
The patent specifies the use of thin-film impermeable gloves that provide pathogen protection while maintaining flexibility and dexterity. The thin-film construction allows the gloves to conform to hand movements and maintain tactile sensitivity, resolving the contradiction between protection and dexterity by using materials that are both barrier-effective and mechanically flexible.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The kit effectively protects handlers from pathogens, deodorizes and disinfects pet waste, reducing manual handling risks and ensuring safe disposal, while maintaining biodegradability and public health safety.
Implementation Method 1
Since high alkalinity (pH>11) and low moisture content are known to be effective in inhibiting bacterial growth, the disinfecting-deodorizing mixture contains one or more highly alkaline compounds, such as lime (calcium hydroxide, also known as hydrated lime). Lime can create pH levels greater than 12, which is sufficient to destroy the cell membranes of most pathogens.
Implementation Method 2
To reduce the moisture content of the treated waste, the disinfecting-deodorizing mixture also contains a desiccant, such as silica, activated charcoal or calcium chloride.
Implementation Method 3
Lime also produces free calcium ions, which are effective in destroying odorous sulfur compounds.

AI summary
A pet waste disposal kit includes a kit bag with an impermeable lining that can be worn around the waist or over the shoulder of the pet handler. The kit bag serves as the secondary container for filled waste collection bags, and it also serves to store the other materials contained in the kit. The kit also includes a supply of lightweight, impermeable, biodegradable plastic gloves, which can be made of biodegradable polyethylene, and a supply of waste collection bags made of lightweight, impermeable, biodegradable plastic, containing a disinfecting-deodorizing mixture. The disinfecting-deodorizing mixture contains a highly alkaline compound, a desiccant and a deodorizer. The waste collection bags have re-sealable zip-locks or twist ties. The kit also includes a supply of antiseptic hand wipes or a liquid hand sanitizer.
