Solution Overview

Problem

Conventional juicers face difficulties in washing the screw assembly with a juice extracting net, and they cannot accommodate various user preferences for juice extraction modes, such as separating juice from residue or using residue in smoothies or milkshakes.

Innovation Solution

A detachable juice extracting screw assembly with a hollow drum and a screw assembly that includes an upper and lower assembly part, where the lower assembly part has a mesh or solid net option, allowing for easy disassembly and selection between different operation modes based on user preferences.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the juice extracting net is included in the screw assembly, then the juice extraction function is improved, but the ease of washing is deteriorated because the screw assembly must be taken out and overturned for washing which makes comprehensive washing difficult and cumbersome

Engineering Contradiction:
Improvejuice extraction functionVSAvoidease of washing
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The screw assembly is divided into an upper assembly part and a lower assembly part that can be easily separated from each other. The juice extracting net is specifically attached to the lower assembly part, allowing users to detach the lower part for convenient washing without disassembling the entire screw assembly. This segmentation enables the washing function to be performed easily while maintaining the complete juice extraction function when assembled.

Inventive Principle:
Principle #1Segmentation

2Ease of manufacture

If the conventional juicer uses a fixed screw assembly structure, then the manufacturing simplicity is improved, but the adaptability is deteriorated because it cannot satisfy various user preferences such as requiring only extracted juice or also requiring residue for smoothies or milkshakes

Engineering Contradiction:
Improvemanufacturing simplicityVSAvoidoperation mode variety
Core Design Contradiction:
Ease of manufactureVSAdaptability or versatility

Solution Approach 1:

The screw assembly is designed with dynamic configurability through the detachable lower assembly part that can be selectively attached or removed. This allows the juicer to operate in different modes: with the lower assembly part attached for juice extraction, or detached for residue-only output suitable for smoothies and milkshakes. The dynamic structure enables multiple operation modes while maintaining manufacturing simplicity through standardized connection interfaces.

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

The solution enables convenient washing of the screw assembly and allows users to easily change operation modes, satisfying various preferences by separating or combining juice and residue according to their needs.

Implementation Method 1

the object for juice extraction is separated into an extracted juice and a residue by rotation of the screw assembly 200

Methodology Applied
Scientific EffectMechanical force: Mechanical Force

Implementation Method 2

the juice passes through the mesh net 276 to flow inwardly to the screw assembly 200 while the residue fails to pass through the mesh net 276

Methodology Applied
Scientific EffectFiltration: Filter (physical)
