Food Processor Insert with Ribs to Reduce Dead-Zones and Improve Flow
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing food processing tools with bell-shaped housings face challenges in guiding food material towards the blade effectively, leading to dead-zones and poor sealing issues, which hinder efficient processing and cleaning.
Innovation Solution
A food processing tool with a housing and integral insert featuring ribs that guide food towards the blade, where the insert is welded to the housing with a gap to enhance flow and sealing, and is designed to conform to the shape of the housing and blades for improved processing efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a bell-shaped housing is used to protect the blade, then safety is improved, but dead-zones are formed above the blade where food is not processed
Solution Approach 1:
The housing is segmented into a bell-shaped outer housing and an inner insert that divides the internal volume. This segmentation creates flow channels that guide food from the bell region down to the blade, eliminating dead-zones while preserving the protective bell shape.
Solution Approach 2:
An inner insert acts as an intermediary component between the bell-shaped housing and the blade. This insert creates a controlled flow path that directs food material away from the dead-zone area and toward the processing blade, resolving the contradiction between safety and processing efficiency.
2Productivity
If ribs are added to guide food towards the blade, then food flow is improved, but the structure becomes more complex
Solution Approach 1:
The ribs are merged with the inner insert as an integrated structure rather than being separate components. This combining of elements provides effective food guidance while avoiding the complexity of additional detachable parts or complex assembly procedures.
3Productivity
If a divider is used to reduce dead-zone space, then processing efficiency is improved, but food can become trapped between the divider and bell
Solution Approach 1:
The insert features locally varied geometry with ribs that have specific spacing and dimensions optimized for different regions. This local quality variation ensures food is guided effectively without creating trapping zones, as the rib configuration allows continuous food flow paths.
4Reliability
If the insert is made integral with the housing, then sealing is improved, but manufacturing complexity increases
Solution Approach 1:
The housing is segmented into two parts: the outer bell-shaped housing and the inner insert. This segmentation allows each component to be manufactured separately using optimized processes, then joined together to achieve both good sealing and manufacturing efficiency.
Solution Approach 2:
The inner insert serves multiple functions: it reduces dead-zones, guides food flow, and provides sealing between itself and the outer housing. This multi-functionality justifies the additional manufacturing step while delivering comprehensive performance benefits.
