Food Processor Friction-Based Helical Feed for One-Handed Operation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vegetable and fruit shredding machines require both hands to operate, leading to uneven shredding thickness and inefficiency due to uneven driving force.
Innovation Solution
A food processor design featuring a base, spindle assembly, bearing assembly, and switching member that generates friction to provide a feed force for spiral movement, allowing one-handed operation and uniform cutting with an eccentric shaft and elastic element for efficient cutting and cleaning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a food processor is designed to accommodate multiple types of food processing operations, then versatility is improved, but device complexity increases
Solution Approach 1:
The food processor is designed with a universal processing chamber that can accommodate multiple types of processing elements (cutting, blending, pureeing, chopping) through a single interface. The processing chamber includes a recessed region that selectively receives different processing elements, allowing one base unit to perform multiple food processing functions without requiring separate devices for each operation type.
2Ease of operation
If a food processor uses a pre-assembled processing element that requires disassembly for cleaning, then ease of operation is improved, but ease of repair worsens
Solution Approach 1:
The processing element is designed as a segmented structure with a body portion and a separately attachable processing portion. The processing portion can be detached from the body portion for cleaning purposes, while the attachment mechanism remains simple enough to allow easy reassembly and replacement. This segmentation allows the processing element to be easily cleaned without requiring disassembly of the entire assembly, and the simple attachment mechanism facilitates easy repair or replacement of individual components.
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
Enables convenient one-handed operation with uniform slicing and shredding thickness, reducing labor and improving ease of use and cleaning by utilizing friction and a helical feed mechanism.
Implementation Method 1
friction is generated between the bearing and the spindle to provide a feed force for driving the spindle to spirally move
Implementation Method 2
the elastic element is in a compression state

AI summary
A food processor includes a base including a first end and a second end, a fixing member, a spindle assembly, a bearing assembly, a switching member mounted on the fixing member, and a cutter. The first end is provided with a tool rest for fixing the cutter to cut food. The fixing member is mounted on the first end. The spindle assembly includes a spindle rotatably mounted on the fixing member and a fluted disc fixed to the spindle for fixing the food. The bearing assembly includes a bearing block mounted on the fixing member and a bearing mounted on the bearing block. When the switching member is in an open position, friction is generated between the bearing and the spindle. When the switching member is in a closed position, the switching member can drive the bearing away from the spindle so that the spindle can freely move.
