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 lid and screw, featuring a crushing blade and concave crushing processing portion that automatically crushes materials as they enter, eliminating the need for pre-chopping and maintaining sieve integrity.

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 is improved, 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 segments: an upper crushing portion with crushing blades for size reduction, and a lower juice extraction portion for extracting juice. This segmentation allows each part to perform its specific function efficiently without requiring the entire screw to be oversized, thus maintaining a compact outer diameter while enabling processing of larger materials.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The invention transitions from a single-dimensional screw extraction mechanism to a two-dimensional approach by adding a crushing portion at the upper end with crushing blades arranged radially. This dimensional addition enables size reduction in the radial direction, allowing larger materials to be processed without increasing the screw's axial length or outer diameter.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

2Productivity

If pre-chopping is required to fit screw blade length, then the screw can extract juice effectively, but user convenience deteriorates

Engineering Contradiction:

Improvejuice extraction efficiencyVSAvoiduser convenience

Core Design Contradiction:

ProductivityVSEase of operation

Solution Approach 1:

The crushing blades on the upper end of the screw perform preliminary size reduction of the material automatically as it is fed into the juicer. This preliminary action eliminates the need for users to pre-chop or pre-cut materials, maintaining high juice extraction efficiency while significantly improving user convenience.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The juicer performs self-service by automatically crushing the material through the crushing blades integrated on the screw. The system handles the size reduction task itself without requiring external preparation by the user, thus maintaining productivity while enhancing ease of operation.

Inventive Principle:

Principle #25Self-service

3Speed

If a grater is used to crush material at high speed, then crushing speed is improved, but the material rotates due to high speed requiring large pressing force

Engineering Contradiction:

Improvecrushing speedVSAvoidpressing force

Core Design Contradiction:

SpeedVSForce

Solution Approach 1:

The crushing blades on the screw perform size reduction before the material reaches the extraction zone. This preliminary crushing action occurs at the optimal speed of the screw rotation, avoiding the high-speed rotation problems of graters, and eliminates the need for large pressing forces to prevent material rotation.

Inventive Principle:

Principle #10Preliminary action

4Productivity

If cut material pieces are pressed against the sieve during extraction, then juice extraction can proceed, but the sieve deforms causing gaps and residue leakage

Engineering Contradiction:

Improvejuice extraction processVSAvoidsieve integrity

Core Design Contradiction:

ProductivityVSReliability

Solution Approach 1:

The crushing blades reduce material size before extraction, creating uniformly small particles that can be processed gently. This preliminary size reduction eliminates the need for aggressive pressing against the sieve, maintaining sieve integrity and preventing deformation, gaps, and residue leakage while still enabling effective juice extraction.

Inventive Principle:

Principle #10Preliminary action
