Food-preparation device suitable for extracting juice and/or coulis
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing food preparation devices with rotary cutting tools are not well-suited for processing soft and/or juicy foods, as they allow juices and small particles to reach the transmission member, leading to potential damage and inefficiency.
Innovation Solution
A food preparation device design featuring a rotary work tool with an annular rib and recess arrangement around the transmission member, along with a chimney for introducing food, which prevents juices and particles from reaching the transmission member, and includes a retention member to manage liquids, promoting better operation and longevity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a rotary cutting tool is used for food processing, then hard foods can be sliced and minced effectively, but soft and juicy foods generate juice and small particles that reach the transmission member causing damage and inefficiency
Solution Approach 1:
The housing is segmented into distinct functional zones: a food introduction zone through the chimney, a processing zone with the rotary tool, and a protected zone for the transmission member. The annular recess and baffle wall create a segmentation barrier that separates the juice-generating processing area from the transmission member area, allowing the device to process juicy foods while protecting the transmission system
Solution Approach 2:
An annular baffle wall is introduced as an intermediary element between the chimney and the transmission member. This baffle wall, positioned within the annular recess, acts as a mediator that blocks the direct path of juices and small particles toward the transmission member while allowing the rotary tool to process foods effectively. The baffle creates a physical barrier that intercepts harmful substances before they reach the transmission system
2Reliability
If the housing structure is modified to prevent juice progression, then transmission member protection is improved, but device complexity increases
Solution Approach 1:
The annular recess and annular baffle wall are merged into a single integrated structural element that forms part of the housing. This combined structure serves multiple functions: it creates the protective barrier against juices, defines the processing chamber geometry, and provides mounting support for the rotary tool. By merging these elements, the design achieves reliable transmission member protection without proportionally increasing device complexity
Solution Approach 2:
The annular recess structure serves multiple functions simultaneously: it acts as a protective barrier for the transmission member, defines the spatial arrangement of the processing chamber, and provides structural support for the rotary tool assembly. This multi-functionality reduces the need for additional separate components, thereby limiting the increase in device complexity while achieving reliable juice containment
