Solution Overview

Problem

Conventional juice extractors with mesh structures suffer from low juice-extracting efficiency due to blockages by debris, making cleaning difficult and prone to germ propagation, as the mesh is easily clogged during the extraction process.

Innovation Solution

A separable screw composed of two modules, where the first module has slits and the second module has ribs that fit into the slits, forming a continuous screw spiral, allowing for easy assembly and disassembly, and a spatial gap to prevent debris from hindering juice flow, with a juice discharge system that separates and expels debris effectively.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a mesh structure is used in the juice-extracting drum, then filtration function is provided, but the mesh is easily blocked by debris and cleaning becomes difficult

Engineering Contradiction:
Improvefiltration functionVSAvoidcleaning difficulty
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The screw is divided into two detachable modules: a first module with slits formed by bars and a second module with ribs. This segmentation allows the components to be separated for easy cleaning while maintaining the filtration function during operation. The slits provide filtering capability without the clogging issues of mesh structures.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The invention extracts the filtration function from a separate mesh drum and integrates it directly into the screw structure through slits formed by bars. This eliminates the need for a separate mesh component that is difficult to clean, while maintaining effective filtration of juice from debris.

Inventive Principle:
Principle #2Taking out (Extraction)

2Productivity

If a conventional netted drum is used, then juice extraction is performed, but debris caught in netted holes decays and germs propagate

Engineering Contradiction:
Improvejuice-extracting efficiencyVSAvoidgerm propagation
Core Design Contradiction:
ProductivityVSObject-affected harmful factors

Solution Approach 1:

The screw is segmented into detachable modules that can be easily separated and cleaned. The slits between bars provide effective filtration while allowing complete removal of debris, preventing the decay and germ propagation that occurs with conventional mesh drums where debris becomes trapped.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The design allows users to easily disassemble and clean the screw components themselves without requiring specialized cleaning tools or procedures. The simple slit structure enables thorough cleaning to prevent contamination.

Inventive Principle:
Principle #25Self-service

3Strength

If the screw is made as a single integrated unit, then structural strength is maintained, but cleaning and maintenance become difficult

Engineering Contradiction:
Improvestructural strengthVSAvoidcleaning ease
Core Design Contradiction:
StrengthVSEase of repair

Solution Approach 1:

The screw is divided into two modules that can be detached from each other, enabling easy cleaning and maintenance of internal surfaces. The modular design maintains structural integrity during operation while allowing complete disassembly for cleaning purposes.

Inventive Principle:
Principle #1Segmentation
