Juice Extraction Receptacle With Grating Disc and Close Filtration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing beverage preparation devices are ineffective in extracting juice from fruit-type foods due to the inability to grind pulp and incomplete juice recovery, as the tool used makes a clean cut and residue at the filter openings prevents juice from passing through to the reservoir zone.
Innovation Solution
A household appliance with a working receptacle featuring a grating disc for grinding various food types, a pusher device with a handle, and a filtration system comprising stackable filtration elements with different diameters, allowing efficient juice extraction and recovery by minimizing the grinding zone volume and utilizing centrifugal force to collect juice in the reservoir.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a rotary tool is used to process fruit-type foods, then the tool makes a clean cut of the pulp food, but it does not allow the food to be reduced by a grinding phenomenon, preventing effective juice extraction
Solution Approach 1:
The patent changes the fundamental parameter of the grinding means from a rotary cutting tool to a grating disc with multiple holes. This parameter change transforms the mechanism from cutting to grinding, enabling effective juice extraction from fruit-type foods while maintaining ease of manufacture through a simple disc structure.
2Reliability
If a filter is used to separate juice from pulp, then filtration is achieved, but residue at the filter openings prevents juice from passing naturally through the filter, causing incomplete juice recovery
Solution Approach 1:
The patent applies preliminary action by using the grating disc to pre-grind the food into a fine paste before filtration. This preliminary grinding action reduces the particle size of the pulp, preventing residue from blocking the filter openings and enabling complete juice passage through the filtration system.
Solution Approach 2:
The grating disc changes the physical state of the food from intact pieces to a fine ground paste. This parameter change in food consistency allows the juice to flow freely through the filter without being blocked by large pulp residues, thereby improving juice recovery completeness.
3Volume of stationary object
If a traditional grinding zone is used with a rotary tool, then the grinding zone volume is relatively large, but this prevents the filtration device from approaching close to the grinding surface, reducing juice recovery efficiency
Solution Approach 1:
The patent segments the grinding function into a flat grating disc with multiple holes, creating a thin grinding surface rather than a volumetric grinding zone. This segmentation allows the filtration device to approach very close to the grinding surface, maximizing juice recovery while minimizing the grinding zone volume.
