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 results in reduced juice extraction efficiency and inconvenience for users.
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 are input, 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 capability to process larger materials is improved, but the outer diameter of the screw increases
Solution Approach 1:
The screw structure is divided into two functional segments: a crushing portion with crushing blades for size reduction, and a conventional screw portion for juice extraction. This segmentation allows the screw to process larger materials without increasing the overall outer diameter, as the crushing function is localized to a specific portion rather than requiring the entire screw to be longer.
Solution Approach 2:
Instead of extending the screw blade length in one dimension to process larger materials, the invention adds a crushing portion that operates in a different dimensional approach - using radial crushing blades that extend outward from the screw axis, enabling size reduction without increasing the axial length or outer diameter of the screw.
2Productivity
If pre-chopping of material is required, then the juice extraction process can proceed, but user convenience deteriorates
Solution Approach 1:
The juicer performs the chopping function automatically through the crushing portion with crushing blades that reduce material size as it enters the extraction chamber. This self-service capability eliminates the need for users to pre-chop materials manually, maintaining extraction efficiency while significantly improving user convenience.
Solution Approach 2:
The crushing portion performs preliminary size reduction action automatically as material enters the juicer, before the main extraction process begins. This preliminary crushing action ensures materials are reduced to appropriate sizes for extraction without requiring user intervention, resolving the contradiction between productivity and ease of operation.
3Productivity
If material is pressed against the sieve during cutting and extraction, then juice extraction can occur, but the sieve may deform
Solution Approach 1:
The processing function is segmented into two stages: crushing in the crushing portion, then extraction in the chamber with the sieve. This segmentation prevents excessive pressing forces from being applied directly to the sieve during the size reduction phase, protecting sieve integrity while maintaining extraction productivity in the second stage.
