Rotary Food Fragmenter Insert for Soft Puree Ejection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing drum-type food preparation devices are inadequate for processing soft foods like cooked potatoes and avocado flesh, as they tend to produce a viscous mash rather than a solid puree, leading to ejection issues and potential clogging.
Innovation Solution
A food preparation device with a rotary work tool featuring a side wall with outer fragmenting members and an insert with deflecting walls that channel processed food into evacuation passages, preventing rotation and facilitating ejection, along with a pusher for efficient food introduction and extraction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a drum-type rotary work tool is used to process soft foods like cooked potatoes, then the food is transformed into a puree, but the viscous nature of the puree causes ejection difficulties and clogging
Solution Approach 1:
The insert is divided into multiple evacuation passages (first, second, and third evacuation passages) distributed around the peripheral direction, allowing the viscous puree to be evacuated through multiple separate channels rather than a single channel, preventing clogging and improving ejection reliability
Solution Approach 2:
The insert acts as an intermediary component between the work tool and the external environment, providing dedicated evacuation passages that facilitate the removal of viscous puree from the work tool interior, preventing direct contact between the puree and the main housing that would cause clogging
2Reliability
If additional evacuation passages are added to the insert, then ejection reliability improves, but device complexity increases
Solution Approach 1:
The insert serves multiple functions simultaneously: it provides structural support, creates multiple evacuation passages for reliable ejection, and distributes puree flow through its multi-passage design. This multi-functionality allows the single component to achieve complex ejection behavior without adding multiple separate parts
Solution Approach 2:
The evacuation passages are strategically positioned at different locations around the insert (first evacuation passage at one location, second and third evacuation passages at another location), creating local evacuation zones that optimize puree flow distribution without requiring a completely complex overall structure
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 device effectively processes soft foods into a puree, ensuring easy ejection and reducing clogging, while being simple to use and maintain, with a balanced distribution of evacuation passages for efficient food collection.
Implementation Method 1
a rotary work tool having a drive end and a side wall extending from the drive end, the side wall having at least one outer fragmenting member adjacent to a through passage
Implementation Method 2
The subsequent action of the work tool produces a mash that behaves more like a viscous fluid than solid food chunks
Implementation Method 3
The subsequent action of the work tool produces a mash that behaves more like a viscous fluid than solid food chunks. The presence of the deflecting walls prevents the food from being rotated inside the working tool and contributes to its evacuation
