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

VSEngineering 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

Engineering Contradiction:
Improveability to process larger materialsVSAvoidouter diameter of screw
Core Design Contradiction:
Adaptability or versatilityVSLength of moving object

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.

Inventive Principle:
Principle #1Segmentation

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.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

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

Engineering Contradiction:
Improvematerial processing capability within limitsVSAvoidpre-chopping time
Core Design Contradiction:
ReliabilityVSLoss of time

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.

Inventive Principle:
Principle #10Preliminary action

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.

Inventive Principle:
Principle #25Self-service

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

Engineering Contradiction:
Improvecrushing speedVSAvoidpressing force required
Core Design Contradiction:
ProductivityVSForce

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.

Inventive Principle:
Principle #15Dynamics

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

Engineering Contradiction:
Improvejuice extraction efficiencyVSAvoidsieve structural integrity
Core Design Contradiction:
ProductivityVSReliability

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.

Inventive Principle:
Principle #10Preliminary action
