Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing juice machines and slow juicers fail to significantly reduce the pressing force on fruits and vegetables and suffer from oxidation issues after squeezing, leading to nutrient loss and compromised juice quality.
Innovation Solution
A food processor design featuring a base assembly, a food processing cup with a working screw, a feeding assembly, and a slag receiving device, which creates a sealed cavity for vacuum operation, allowing for reduced pressing force and minimized oxidation by maintaining a vacuum state during processing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If traditional juice machines operate under normal pressure, then the structure is simple and easy to manufacture, but the pressing force on fruits and vegetables is insufficient and oxidation occurs after squeezing
Solution Approach 1:
The patent creates a vacuum environment inside the cup body to replace normal atmospheric pressure operation. The vacuum state prevents oxidation of juice by removing oxygen, while also enabling more efficient juice extraction from fruits and vegetables without requiring additional complex pressing mechanisms
2Object-affected harmful factors
If a vacuum environment is created for processing, then oxidation is reduced and nutrient preservation is improved, but the device complexity increases due to sealing requirements
Solution Approach 1:
The patent integrates the sealing function into the existing cup body structure rather than adding separate sealing components. The feeding assembly is sealed mounted directly on the cup body, and the slag receiving device is hermetically connected to the first slag outlet, combining multiple functions into unified structures to minimize complexity while maintaining vacuum integrity
Solution Approach 2:
The cup body serves multiple functions: it acts as the processing chamber, contains the vacuum environment, collects juice, and provides mounting surfaces for sealed connections. This multi-functionality reduces the need for additional specialized components that would increase device complexity
3Device complexity
If the cup body is used to collect juice, then additional juice receiving structures are eliminated and costs are reduced, but the sealing performance must be maintained throughout the processing process
Solution Approach 1:
The patent combines the juice collection function with the existing cup body structure, eliminating the need for separate juice receiving containers. The cup body's inner cavity serves as both the processing chamber and juice collection reservoir, simplifying the overall structure while maintaining reliable sealing through integrated design
4Object-affected harmful factors
If the slag receiving device is hermetically connected to the first slag outlet, then the slag outlet remains sealed during operation preventing oxygen entry, but the device complexity increases
Solution Approach 1:
The patent integrates the slag receiving device directly with the cup body through hermetic connection at the first slag outlet. This unified design allows the slag outlet to remain sealed during operation, preventing oxygen from entering the vacuum environment, while avoiding the complexity of separate sealing mechanisms through structural integration
