Solution Overview

Problem

Conventional juicers fail to adequately chop fruits and vegetables, resulting in juice with high solid content, clogged outlets, and cumbersome operation, leading to a poor user experience and increased maintenance costs.

Innovation Solution

A juicer with an autonomous circulation filtration function, featuring a container, rotating cutter, filter barrel, and return pipe that refluxes juice for filtering, along with a pressing rod and juice guiding bridge, effectively reduces solid particles and prevents outlet blocking, enhancing the juicing process and user experience.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If conventional juicer uses simple chopping mechanism, then device complexity is low, but manufacturing precision of juice quality deteriorates

Engineering Contradiction:
Improvechopping mechanism complexityVSAvoidjuice quality
Core Design Contradiction:
Device complexityVSManufacturing precision

Solution Approach 1:

The juicer is divided into distinct functional modules: a chopping assembly with cutter head for initial fruit breakdown, and a separate grinding assembly with grinding roller for fine particle reduction. This segmentation allows each module to specialize in a specific task, achieving high juice quality without requiring the entire device to be overly complex.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The chopping assembly performs preliminary chopping of fruits before the grinding assembly processes them further. This preliminary action breaks down large fruit pieces into smaller fragments, making the subsequent grinding operation more effective and enabling fine particle reduction without excessive complexity.

Inventive Principle:
Principle #10Preliminary action

2Device complexity

If conventional juicer lacks filtration function, then device complexity is low, but harmful factors increase due to outlet blocking

Engineering Contradiction:
Improvefiltration system complexityVSAvoidoutlet blocking
Core Design Contradiction:
Device complexityVSObject-generated harmful factors

Solution Approach 1:

The filter barrel is positioned to receive juice and fruit particles during the grinding process, performing preliminary filtration before juice exits the device. This preliminary filtration action prevents solid particles from accumulating and blocking the outlet, eliminating the harmful effect without requiring a separate complex filtration system.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The filtration function is merged with the existing grinding and juice discharge pathway. The filter barrel integrates into the juice flow path, combining filtration with the primary juicing operation, thereby preventing outlet blocking without adding significant device complexity.

Inventive Principle:
Principle #5Merging (Combining)

3Device complexity

If conventional juicer requires manual operation, then device complexity is low, but ease of operation deteriorates

Engineering Contradiction:
Improvecontrol system complexityVSAvoidoperation convenience
Core Design Contradiction:
Device complexityVSEase of operation

Solution Approach 1:

The control assembly enables automatic control of the juicer operation. Users can set parameters such as grinding time and speed, and the system automatically executes the juicing process without requiring manual intervention during operation. This self-service capability significantly improves ease of operation while maintaining reasonable device complexity through automated control.

Inventive Principle:
Principle #25Self-service

4Device complexity

If conventional juicer lacks circulation function, then device complexity is low, but productivity deteriorates due to incomplete grinding

Engineering Contradiction:
Improvecirculation system complexityVSAvoidjuicing efficiency
Core Design Contradiction:
Device complexityVSProductivity

Solution Approach 1:

The circulation assembly creates a feedback loop where juice and unground particles are returned from the filter barrel to the grinding assembly for further processing. This feedback mechanism ensures that particles are ground to the desired fineness before juice extraction, improving juicing efficiency and productivity without requiring excessive device complexity.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The circulation system maintains continuous grinding action by repeatedly passing juice and particles through the grinding assembly until adequate fineness is achieved. This continuous useful action ensures complete grinding and maximizes juice extraction efficiency, improving productivity while keeping the circulation system relatively simple.

Inventive Principle:
Principle #20Continuity of useful action
