Juice extraction module for juicer
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 can result in reduced juice extraction efficiency and leakage.
Innovation Solution
A juice extraction module with a crushing portion on the screw and a concave crushing processing portion in the lid, featuring a crushing blade and material guide surface, allows for automatic 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 ability to process larger materials improves, 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 with traditional extraction blades. 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 blade length.
Solution Approach 2:
The crushing blades are positioned in the upper portion of the screw, utilizing the vertical dimension (height) rather than increasing the radial dimension (outer diameter). This allows the screw to accommodate larger materials by processing them vertically at the top before extraction, without expanding the screw's outer diameter.
2Reliability
If pre-chopping is required to fit screw blade length, then the ability to process materials within screw limits is maintained, but the operation complexity and time increase
Solution Approach 1:
The crushing blades perform preliminary size reduction action automatically as materials enter the juicer through the input port. This preliminary crushing occurs before the materials reach the extraction portion, eliminating the need for users to pre-chop materials externally, thus saving preparation time while ensuring materials are reduced to appropriate sizes for extraction.
Solution Approach 2:
The juicer performs self-service by automatically crushing materials that are fed through the input port. The crushing portion processes materials without requiring external intervention or pre-chopping by the user, making the system self-sufficient for handling various material sizes.
3Productivity
If a grater is used to crush materials at high speed, then crushing efficiency improves, but the material must be pressed with large force to prevent rotation
Solution Approach 1:
The crushing blades are integrated with the rotating screw mechanism, so they rotate at the same speed as the screw extraction process. This dynamic integration eliminates the need for separate high-speed grating mechanisms that require additional pressing force, as the crushing action is performed naturally by the rotating blades during the normal extraction speed.
4Productivity
If cut material pieces are pressed against the sieve during extraction, then juice extraction is facilitated, but the sieve may deform causing leakage and reduced efficiency
Solution Approach 1:
The crushing blades reduce materials to smaller pieces before they reach the sieve, so that by the time materials contact the sieve, they are already sufficiently broken down. This preliminary size reduction minimizes the pressing force needed against the sieve, preventing deformation while still enabling effective juice extraction.
