Solution Overview

Problem

Conventional juicers face issues with remnants being mixed with the juice due to the structural placement of the engagement gear, which limits the design freedom of the juice squeezing drum and leads to inefficient juice extraction.

Innovation Solution

The engagement gear for the rotating brush is positioned on the edge of the bottom surface of the juice squeezing drum, rather than the area where the juice squeezing screw is mounted, and a gear module is used to transmit the driving force from the driving shaft to the engagement gear, allowing for improved design freedom and prevention of remnants entering the juice.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If the engagement gear is disposed on the bottom surface of the juice squeezing drum where the juice squeezing screw is mounted, then the structure is compact, but remnants are mixed with the discharged juice and design freedom is limited

Engineering Contradiction:

Improvestructural compactnessVSAvoidremnants mixing with juice

Core Design Contradiction:

Ease of manufactureVSObject-affected harmful factors

Solution Approach 1:

The engagement gear is relocated from the horizontal plane (bottom surface of the drum) to the vertical dimension (underside of the drum), allowing it to be positioned at the peripheral edge where it cannot contaminate the juice discharge area while maintaining structural integration

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

2Ease of operation

If the engagement gear is disposed on the bottom surface of the juice squeezing drum, then the brush can be rotated effectively, but the design freedom of the juice squeezing drum is decreased

Engineering Contradiction:

Improvebrush rotation effectivenessVSAvoiddesign freedom of juice squeezing drum

Core Design Contradiction:

Ease of operationVSAdaptability or versatility

Solution Approach 1:

By moving the engagement gear to the underside peripheral edge, the design allows independent optimization of the drum's bottom surface for juice discharge while the gear engages with the brush ring gear through the drum thickness, maintaining brush rotation functionality without constraining drum design

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

Solution Approach 2:

The engagement gear is separated into a distinct component mounted on the underside of the drum, independent from the juice squeezing screw mounting area, allowing each component to be optimized for its specific function without interference

Inventive Principle:

Principle #1Segmentation
