Juice module for juicer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional juicers require pre-cutting of juice objects larger than the screw blade length, leading to deformation of mesh bodies, reduced bonding force, and decreased juice extraction efficiency, with high-speed crushing posing safety risks and increased user effort.
Innovation Solution
A dual input structure juice module with a crushing portion and support surface on the screw, allowing low-speed crushing before reaching the spiral rib, and a lid with multiple inlets for different object sizes, eliminating the need for pre-cutting and enhancing safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If a steel plate is used for high-speed crushing, then crushing speed is improved, but user effort and safety risks increase
Solution Approach 1:
The patent changes the operating speed parameter from high-speed to low-speed crushing, eliminating the need for high user effort while maintaining effective crushing through the screw's spiral rib structure that progressively breaks down the juice object
2Ease of operation
If the input portion is enlarged to accept whole juice objects, then ease of operation is improved, but safety risks increase
Solution Approach 1:
The patent segments the input portion into two separate inlets: a first inlet for smaller juice objects and a second inlet for larger juice objects. This segmentation allows the acceptance of whole objects without enlarging the overall input area, maintaining safety while improving ease of operation
3Productivity
If mesh body is pressed into by cut mass, then juice extraction is improved, but mesh body deformation occurs
Solution Approach 1:
The patent applies preliminary crushing action through the screw's crushing portion and spiral rib before the juice object reaches the mesh body. This preliminary action breaks down the juice object into smaller pieces that can be easily pressed through the mesh body without causing deformation, ensuring both high juice extraction rate and mesh body stability
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Reduces motor load, prevents mesh body deformation, maintains juice extraction efficiency, and ensures safe operation by allowing juice objects of various sizes to be input without prior cutting, while minimizing safety risks.
Implementation Method 1
a screw mounted inside the mesh body to rotate with respect to a screw rotation shaft, having a spiral rib formed on an outer circumferential surface
Implementation Method 2
receiving and crushing the juice object from the lid
Implementation Method 3
a support surface formed in a direction intersecting the screw rotation shaft to support the juice object input into the lid
Implementation Method 4
a crushing portion formed on an upper end to intersect the support surface and cutting the juice object
Implementation Method 5
a mesh body separating juice and residue
