Grinding Mechanism With Integrated Projections And Attachable Inserts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional food waste disposers have inefficiencies in material usage and assembly processes due to the separate fabrication and assembly of a stationary grinding ring, leading to redundant material usage, increased production costs, and limitations in adjusting grinding performance.
Innovation Solution
The use of a grinding section with projections formed in the internal wall of the housing and attachable grinding inserts eliminates the need for a separate grinding ring, allowing for incremental adjustments in grinding performance without dedicated tooling and reducing inventory costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a separate stationary grinding ring is fabricated and mechanically inserted into the housing, then the grinding function is achieved, but material waste increases and production complexity increases
Solution Approach 1:
The patent merges the stationary grinding ring with the housing by forming grinding teeth directly on the housing inner surface. This eliminates the separate grinding ring component, reduces material waste, and simplifies the manufacturing process while maintaining the grinding function.
Solution Approach 2:
The housing serves dual functions: it provides structural containment and simultaneously performs the grinding function through integrated teeth. This multi-functionality eliminates the need for a separate grinding ring and reduces overall part count.
2Ease of manufacture
If a separate stationary grinding ring is fabricated and mechanically inserted into the housing, then the grinding function is achieved, but assembly complexity increases
Solution Approach 1:
By integrating the grinding teeth directly into the housing structure, the patent eliminates the separate grinding ring component and its associated assembly steps. This reduces assembly complexity while maintaining the grinding function.
3Adaptability or versatility
If dedicated tooling is used for each grinding ring variant, then grinding performance can be adjusted, but production costs increase
Solution Approach 1:
The patent enables dynamic adjustment of grinding performance by allowing different tooth configurations to be formed on the housing using reconfigurable tooling or additive manufacturing techniques. This provides adaptability without requiring dedicated tooling for each variant, reducing production costs.
4Adaptability or versatility
If multiple variant grinding rings are produced, then performance variation is achieved, but inventory costs increase
Solution Approach 1:
The housing serves as a universal base that can accommodate different tooth configurations for various grinding performance requirements. This eliminates the need to maintain separate grinding ring inventories, as the same housing can be reconfigured for different applications.

AI summary
Grinding sections for food waste disposers, food waste disposers having grinding sections, and methods of manufacturing food waste disposers having grinding sections are disclosed herein. The grinding sections include an internal wall having a plurality of projections extending into the food receiving area. Grinding inserts are attached to each projection. The grinding sections may be made by molding the grinding section housing with the projections and attaching the grinding inserts into the projections.
