Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Food waste disposers are prone to microbial growth, leading to unpleasant odors, slimy films, and potential degradation of components, with existing technologies only partially addressing the issue through limited antimicrobial treatments.
Innovation Solution
Incorporating antimicrobial agents into various components of food waste disposers, such as metal, plastic, and rubber parts, through embedding or coating, to inhibit microbial growth, including the use of silver-based additives and coatings like AGION to provide long-term protection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If antimicrobial agents are embedded or coated into components, then microbial growth is reduced and components stay cleaner, but the complexity of the device increases
Solution Approach 1:
The patent applies composite materials by combining antimicrobial agents with polymer matrices to create integrated components. The antimicrobial agent is incorporated into the polymer during the molding process, creating a unified material that provides both structural function and antimicrobial protection, thereby reducing device complexity while maintaining reliability.
Solution Approach 2:
The antimicrobial components provide self-service by continuously inhibiting microbial growth without requiring external intervention. The embedded antimicrobial agents remain active throughout the component's service life, automatically preventing bacterial proliferation and eliminating the need for manual cleaning or chemical treatments, thus reducing operational complexity.
2Object-generated harmful factors
If antimicrobial agents are applied to components, then odor formation is prevented, but the manufacturing process becomes more complex
Solution Approach 1:
The patent implements preliminary action by incorporating antimicrobial agents into components during the initial molding process. The antimicrobial material is mixed with the polymer resin before molding, ensuring that the antimicrobial properties are built-in from the start. This preliminary integration prevents odor formation throughout the component's life while avoiding complex post-manufacturing treatment steps.
3Reliability
If multiple types of antimicrobial treatments are applied to different components, then comprehensive protection is achieved, but the device complexity increases
Solution Approach 1:
The patent applies universality by using a single antimicrobial material system that can be integrated into multiple different component types (polymers, rubbers, metals) through standardized incorporation methods. This multi-functional approach provides comprehensive protection across all components while maintaining manufacturing simplicity, as the same antimicrobial agent can be used throughout the entire disposer system.
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 solution effectively reduces microbial growth, maintains cleaner conditions, and extends the longevity of disposer components by preventing degradation and odor formation.
Implementation Method 1
The component can be formed with an antimicrobial agent embedded therein or can be coated or powder coated with an antimicrobial agent. The antimicrobial agent can be, for example, AGION, which contains silver and other metals.
Implementation Method 2
The antimicrobial agent can be, for example, AGION, which contains silver and other metals. These metals have inherent antimicrobial properties that prevent microbial degradation of organic materials.

AI summary
A food waste disposer having one or more antimicrobial components is disclosed. The components can be metal, plastic, or rubber, and preferably constitute at least those components that a user could come in contact with during operation or maintenance of the disposer and/or components that come in contact with food waste. The plastic and rubber components can either be embedded or coated with an antimicrobial agent. The metal components are preferably powder coated. Exemplary components within the disposer benefiting from such antimicrobial treatment include a metal shredder plate, a metal shredder ring, a rubber mounting gasket, a rubber vibration isolation mount, a rubber vibration isolation tailpipe coupling, and the plastic discharge outlet and associated rubber seals.
