Juicer Screw Crushing Structure for Large-Ingredient Extraction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional juicers require pre-chopping of materials due to limitations in screw blade length, leading to inconvenience and potential sieve deformation, which reduces juice extraction efficiency and increases the risk of residue leakage.
Innovation Solution
A juice extraction module with a crushing portion on the screw and a concave crushing processing portion in the lid, allowing for automatic crushing of materials as they enter, eliminating the need for pre-chopping and maintaining sieve integrity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the screw blade length is increased to process larger materials, then the ability to process larger materials is improved, but the outer diameter of the screw increases
Solution Approach 1:
The screw is divided into two functional sections: an upper crushing portion with crushing blades for size reduction, and a lower juice extraction portion for extracting juice. This segmentation allows the screw to process larger materials without increasing its overall outer diameter, as the crushing function is added as a separate upper section rather than extending the extraction section.
Solution Approach 2:
The crushing blades are arranged in a spiral pattern around the upper portion of the screw, utilizing the vertical dimension and rotational arrangement rather than simply extending the horizontal length. This allows the crushing function to be integrated into the screw's structure without proportionally increasing its outer diameter.
2Device complexity
If materials are pre-chopped before input, then the juice extraction process is simplified, but user convenience deteriorates
Solution Approach 1:
The crushing blades on the upper portion of the screw perform preliminary size reduction of the material automatically as it is fed into the juicer. This preliminary action occurs within the juicer itself rather than requiring pre-processing by the user, eliminating the need for separate chopping while maintaining extraction efficiency.
Solution Approach 2:
The juicer performs the crushing function automatically through its built-in crushing blades, making the system self-sufficient for size reduction. Users simply need to feed whole or large pieces of material into the juicer, and the crushing mechanism handles the rest without requiring user intervention or pre-preparation.
3Productivity
If the screw blade is used to cut materials, then juice extraction can proceed, but the sieve may be deformed causing residue leakage
Solution Approach 1:
The screw is segmented into crushing blades on the upper portion and extraction blades on the lower portion. The crushing blades perform size reduction without direct contact with the sieve, while the extraction blades handle juice extraction. This separation prevents the high-force cutting action from deforming the sieve while maintaining effective juice extraction.
Solution Approach 2:
The crushing blades perform size reduction of the material before it reaches the sieve area. By pre-crushing the material in the upper portion, the material is reduced to appropriate sizes that can be processed by the extraction blades without exerting excessive force on the sieve, thereby preventing deformation and residue leakage.
