Food preparation device including at least one working tool
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing food preparation devices are complex to manufacture due to mechanical stresses and weight issues caused by a gooseneck design, which increases manufacturing costs and complexity, especially in the feed chute mechanism.
Innovation Solution
A food preparation device with a housing that has a drive device and a support portion forming a support plane with the axis of rotation angled between 0° to 20°, eliminating the need for a gooseneck and allowing the working tool to be driven peripherally, simplifying the internal structure and reducing mechanical stresses.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a gooseneck design with recess is used to collect worked food, then food collection is improved, but mechanical stresses and weight increase significantly
Solution Approach 1:
Instead of having food fall downward into a recess (gooseneck design), the patent inverts the approach by having the working tool rotate horizontally at the periphery, allowing food to be worked and discharged laterally through an orifice in the housing wall. This eliminates the need for a downward recess structure.
Solution Approach 2:
The patent transitions from a vertical food collection approach (gooseneck recess) to a horizontal working approach. The working tool rotates in a horizontal plane perpendicular to the support plane, discharging food laterally through an orifice, thereby eliminating the need for vertical recess structures.
2Ease of operation
If a gooseneck design with recess is used to collect worked food, then food collection is improved, but device complexity increases
Solution Approach 1:

This eliminates the need for a downward recess structure.
Solution Approach 2:
The patent transitions from a vertical food collection approach (gooseneck recess) to a horizontal working approach. The working tool rotates in a horizontal plane perpendicular to the support plane, discharging food laterally through an orifice, thereby eliminating the need for vertical recess structures.
3Adaptability or versatility
If a pivotable feed chute is used to occupy different positions, then feeding flexibility is improved, but device complexity increases
Solution Approach 1:
The housing serves multiple functions: it provides structural support, contains the drive mechanism, and incorporates an orifice for food discharge. The peripheral rotation of the working tool allows the same structure to handle both working and discharge functions without requiring separate pivotable feed chutes.
4Stability of the object's composition
If the axis of rotation is vertical, then working tool stability is improved, but housing structure complexity increases due to gooseneck requirement
Solution Approach 1:
The patent changes the orientation of the rotation axis from vertical to horizontal, with the axis of rotation being perpendicular to the support plane. This allows the working tool to rotate in a vertical plane, maintaining stability while eliminating the need for a gooseneck housing structure.
Solution Approach 2:
Instead of having the working tool rotate vertically around a vertical axis (requiring gooseneck), the patent inverts the approach by having the working tool rotate around a horizontal axis perpendicular to the support plane, allowing food to be discharged laterally through an orifice in the housing wall.
