Solution Overview
Problem
Existing juice machines have complex structures with numerous parts, making them difficult to clean and resulting in low juice yield due to insufficient squeezing and small filter screen holes.
Innovation Solution
A food processor design featuring a vertically arranged first barrel body and a second barrel body at an angle greater than 70°, eliminating the need for filter screens and rotary brushes by separating crushing and juice extrusion processes, with a horizontal extrusion system for efficient juice and residue separation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If vertical juice machines use spiral heads and filter screens with rotary brushes, then juicing function is achieved, but the structure becomes complex with numerous parts and complicated mounting
Solution Approach 1:
The device is divided into two separate barrel bodies: a first barrel body for crushing and a second barrel body for extrusion. This segmentation allows each component to have a dedicated function, eliminating the need for filter screens and rotary brushes in the crushing section, thereby reducing structural complexity and cleaning requirements.
Solution Approach 2:
The filter screen and rotary brush components are completely removed from the system. The patent achieves juice-residue separation through the extrusion device in the second barrel body without requiring traditional filter screens, thus eliminating the harmful factors associated with complex filtering mechanisms.
2Productivity
If filter screens with small holes are used for juice separation, then juice yield is improved, but cleaning becomes difficult and structure complexity increases
Solution Approach 1:
The filter screen is completely removed from the system. Instead of using a filter screen with small holes for juice separation, the patent employs an extrusion device that separates juice from residues through mechanical extrusion in the second barrel body, achieving high juice yield without the complexity of filtering structures.
Solution Approach 2:
The patent changes the separation mechanism from filtration-based (using small holes) to extrusion-based. The extrusion device applies mechanical pressure to force juice through residues, changing the separation parameter from pore size to applied pressure, thereby simplifying the structure while maintaining or improving juice yield.
3Device complexity
If horizontal juice machines are used for extrusion, then structure is simpler, but squeezing is insufficient and juice yield is low
Solution Approach 1:
The patent combines vertical and horizontal configurations by using a vertically arranged first barrel body for crushing and a second barrel body arranged at an angle of 70-180 degrees for horizontal extrusion. This segmented approach allows the extrusion section to operate horizontally for sufficient squeezing while keeping the overall structure simpler than traditional vertical machines.
Solution Approach 2:
The patent transitions from a purely vertical or purely horizontal configuration to a combined configuration where the second barrel body is arranged at an angle of 70-180 degrees relative to the first barrel body. This dimensional change optimizes the extrusion angle for better squeezing efficiency while maintaining structural simplicity.
4Reliability
If multiple components like rotary brushes and filter screens are added, then juicing function is enhanced, but cleaning difficulty increases and user experience deteriorates
Solution Approach 1:
The rotary brush and filter screen components are completely removed from the system. The patent achieves reliable juice extraction and separation functions using only the crushing device in the first barrel body and the extrusion device in the second barrel body, eliminating the need for additional cleaning-prone components and thereby improving ease of operation and user experience.
