Juicer Screw Crushing Module for Whole-Ingredient Juice Extraction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional juicers require pre-chopping of materials due to limitations in screw blade length, leading to inefficiencies and potential sieve deformation, which reduces juice extraction efficiency and increases user inconvenience.
Innovation Solution
A juice extraction module with a crushing portion on the lid and screw, featuring a crushing blade and concave crushing processing portion that accommodates the screw, allowing for in-situ crushing of materials without increasing the outer diameter of the screw, enabling the processing of larger-sized materials without pre-chopping.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the screw blade length is increased to process larger materials, then the capability to process larger materials is improved, but the outer diameter of the screw and related components must be enlarged
Solution Approach 1:
The material processing function is segmented into two distinct stages: a crushing stage performed by the crushing blade on the screw before material enters the sieve, and a juicing stage performed by the screw pressing material against the sieve. This segmentation allows the screw to focus on juicing while the crushing blade handles size reduction, enabling processing of larger materials without requiring an enlarged screw diameter.
Solution Approach 2:
The crushing blade is positioned at the top end of the screw, utilizing the vertical dimension above the sieve rather than extending the screw blade laterally. This dimensional repositioning allows the screw to maintain its original outer diameter while still providing the capability to process larger materials through the vertically arranged crushing mechanism.
2Productivity
If pre-chopping of material is required, then the screw can extract juice effectively, but user convenience and operational efficiency deteriorate
Solution Approach 1:
The crushing blade performs preliminary size reduction of the material directly in the juicer before the juicing process begins. This preliminary action eliminates the need for users to pre-chop materials externally, maintaining juice extraction efficiency while significantly improving ease of operation by allowing users to insert whole or large pieces of material directly into the input port.
Solution Approach 2:
The juicer performs the crushing function autonomously through the crushing blade integrated with the screw mechanism. The system serves itself by automatically reducing material size without requiring external preparation, thereby eliminating the inconvenient pre-chopping step while maintaining effective juice extraction.
3Productivity
If a grater is used to crush material at high speed, then crushing capability is improved, but the material rotates due to high speed requiring large pressing force
Solution Approach 1:
The crushing blade rotates at the same speed as the screw, creating a dynamic system where the relative motion between the crushing blade and material is controlled. This synchronized rotation prevents the material from spinning uncontrollably, allowing effective crushing with moderate pressing force rather than requiring excessive force to counteract high-speed rotation.
Solution Approach 2:
The screw serves multiple functions: it acts as both the juicing element that presses material against the sieve and as the rotating component that drives the crushing blade. This multi-functionality ensures that the crushing and juicing operations are coordinated, allowing the material to be crushed and then immediately pressed without requiring separate high-speed crushing mechanisms that would demand large pressing forces.
4Productivity
If cut pieces of material are pressed against the sieve during juicing, then juice extraction is achieved, but the sieve may be deformed by the pressed cut pieces
Solution Approach 1:
The crushing blade performs size reduction of material before it reaches the sieve, creating smaller, more uniform particles that are easier to press against the sieve without causing deformation. This preliminary size reduction maintains juice extraction efficiency while protecting the sieve's structural integrity by preventing large cut pieces from deforming the sieve during pressing.
