Solution Overview
Problem
Existing juice machines with single-shaft output configurations face difficulties in cleaning the filter screen due to residue accumulation during fruit processing, as the large squeezing force leaves fruit residues on the filter screen, making it hard to clean.
Innovation Solution
A drive assembly with multi-shaft output is introduced, featuring a single drive body that powers two separate drive shafts, allowing for independent operation of smashing and squeezing processes without the need for a filter screen, thereby simplifying the structure and reducing parts in the food processor.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single-shaft output configuration is used to drive the spiral head for pulverizing and squeezing fruits, then the structure is simple, but fruit residues accumulate on the filter screen making it difficult to clean
Solution Approach 1:
The patent divides the single drive shaft into two separate drive shafts (first drive shaft and second drive shaft), each independently driving different components. The first drive shaft drives the spiral head for pulverizing, while the second drive shaft drives the squeezing component. This segmentation allows the squeezing force to be applied without requiring a filter screen, thereby eliminating the cleaning problem while maintaining structural simplicity through the use of a single motor.
Solution Approach 2:
The patent removes the filter screen component from the system by implementing separate pulverizing and squeezing functions through two drive shafts. The squeezing function is achieved through the second drive shaft driving a squeezing component that directly separates juice from residues without needing filtration, thus extracting and eliminating the problematic filter screen that required cleaning.
2Device complexity
If a single-shaft output configuration is used, then the device has fewer parts, but the smashing and squeezing processes cannot be separated
Solution Approach 1:
The patent segments the single drive shaft function into two independent drive shafts, allowing the smashing process (driven by first drive shaft) and squeezing process (driven by second drive shaft) to operate independently. This enables separate control and optimization of each process while still using a single motor, thus achieving process separation without significantly increasing the number of parts.
Solution Approach 2:
The single motor serves multiple functions by driving both the first drive shaft for smashing and the second drive shaft for squeezing through a transmission mechanism. This multi-functionality allows the device to perform both smashing and squeezing processes with a single power source, maintaining simplicity while achieving process separation and versatility.
3Reliability
If a filter screen is used for separating juice from residues, then separation is achieved, but the structure becomes more complex and manufacturing costs increase
Solution Approach 1:
The patent extracts and removes the filter screen from the system by implementing a mechanical squeezing separation mechanism. The second drive shaft drives a squeezing component that physically separates juice from fruit residues through mechanical pressure, achieving effective juice separation without the need for a filter screen, thereby reducing structural complexity.
Solution Approach 2:
The patent replaces the filtration mechanism (filter screen) with a mechanical squeezing mechanism driven by the second drive shaft. Instead of using a passive filter screen to separate juice from residues, the system uses an active mechanical squeezing component that applies pressure to extract juice, achieving separation through mechanical action rather than filtration, thus reducing structural complexity.

AI summary
The present disclosure provides a drive assembly and a food processor. The drive assembly comprises: a drive body; and a transmission assembly comprising at least a first transmission member and a second transmission member, the first transmission member being in driving connection with the drive body and provided thereon with a first drive shaft, and the second transmission member being in driving connection with the drive body and provided thereon with a second drive shaft. The technical solution is capable of driving, using a single drive body, at least two drive shafts to move, so that multi-shaft output with a single drive body can be realized.
