Solution Overview

Problem

Conventional juicers face reduced juicing efficiency due to uniform compression of all materials with the same driving force, regardless of the type of material being juiced, leading to suboptimal juice extraction rates and residual heavy metal discharge.

Innovation Solution

A juicer design that allows for variable motor speed adjustment based on material type through control of pressure, current, and voltage, with the option for automatic or manual adjustment, and incorporates a sludge compressing force generator and sensor-operated components to optimize juicing efficiency.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If uniform compression force is applied to all materials, then the device structure remains simple, but the juicing rate significantly reduces

Engineering Contradiction:
Improvejuicing rateVSAvoiddevice structure
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent applies dynamics by making the compression force variable rather than uniform. The first compression roller applies a first compression force while the second compression roller applies a second compression force that is different from the first, allowing the system to adapt to different material types and improve juicing rate without requiring complete structural redesign.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent implements local quality by creating different compression conditions at different locations. The dual compression roller structure provides locally optimized compression forces - the first roller provides initial compression while the second roller provides additional compression with a different force magnitude, tailoring the compression characteristics to specific material requirements.

Inventive Principle:
Principle #3Local quality

2Productivity

If high compression force is applied to extract more juice, then juice extraction rate improves, but residual heavy metal discharge increases

Engineering Contradiction:
Improvejuice extraction rateVSAvoidresidual heavy metal discharge
Core Design Contradiction:
ProductivityVSObject-generated harmful factors

Solution Approach 1:

The patent applies parameter changes by varying the compression force parameter across different rollers. By setting the second compression force differently from the first compression force, the system optimizes juice extraction while controlling the conditions that lead to heavy metal discharge, achieving a balance between extraction efficiency and contamination control.

Inventive Principle:
Principle #35Parameter changes

3Productivity

If single-stage compression is used, then the device structure remains simple, but the juicing efficiency is suboptimal

Engineering Contradiction:
Improvejuicing efficiencyVSAvoidcompression stages
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent applies segmentation by dividing the compression process into multiple stages with different compression rollers. The first compression roller performs initial compression while the second compression roller performs additional compression with a different force, breaking down the juicing process into manageable segments that collectively improve efficiency.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent implements dynamics by creating a multi-stage compression system where each stage applies a different compression force. This dynamic approach allows optimization of juicing efficiency through progressive compression while maintaining a relatively simple overall device structure.

Inventive Principle:
Principle #15Dynamics
