Solution Overview

Problem

Conventional juice extractors face inefficiencies in handling large amounts of pulp, leading to frequent emptying of the pulp receptacle due to reliance on gravity, which limits the receptacle's capacity and design flexibility.

Innovation Solution

A juice extractor with a pulp pushing section that actively expels pulp using a blade and rib mechanism, promoting radial and axial movement to ensure complete filling of the receptacle, even when it has a complex shape, and reducing the overall size of the extractor.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If the receptacle size is increased to handle larger amounts of pulp, then the pulp capacity is improved, but the overall size of the juice extractor increases

Engineering Contradiction:
Improvepulp capacityVSAvoidoverall size of juice extractor
Core Design Contradiction:
Quantity of substanceVSVolume of moving object

Solution Approach 1:

The invention changes the pulp discharge direction from vertical (downward) to radial (horizontal), allowing the receptacle to be positioned in the radial direction rather than extending vertically. This dimensional change enables the main body to be compact while the receptacle can be placed in previously unused radial space, effectively increasing pulp capacity without increasing the overall height or vertical footprint of the juice extractor.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Productivity

If the receptacle is designed with complex shape to optimize space utilization, then the space efficiency is improved, but the manufacturing complexity increases

Engineering Contradiction:
Improvespace efficiencyVSAvoidmanufacturing complexity
Core Design Contradiction:
ProductivityVSEase of manufacture

Solution Approach 1:

The invention divides the pulp discharge system into separate functional sections: the food processing chamber, the pulp pushing section with blade and rib mechanisms, and the receptacle. This segmentation allows each component to be manufactured independently using simpler processes, while the overall system achieves high space efficiency through optimized spatial arrangement. The receptacle can have complex shapes for space optimization without complicating the manufacturing of individual components.

Inventive Principle:
Principle #1Segmentation

3Device complexity

If the pulp is allowed to exit through gravity only, then the device complexity is reduced, but the receptacle fills up prematurely and requires frequent emptying

Engineering Contradiction:
Improvepulp discharge mechanism complexityVSAvoidreceptacle filling efficiency
Core Design Contradiction:
Device complexityVSProductivity

Solution Approach 1:

The invention employs self-service mechanisms where the rotating blade and stationary rib structures automatically push pulp into the receptacle without requiring external power sources or complex control systems. The blade, driven by the spindle rotation, and the stationary ribs work together to create a self-propelling effect that moves pulp radially outward and downward into the receptacle, ensuring continuous and efficient filling without adding significant device complexity.

Inventive Principle:
Principle #25Self-service

AI summary

A juice extractor comprising a main body comprising a food inlet, a juice outlet, a pulp discharge opening. The main body delimits a food processing chamber with a food compression section arranged between said food inlet and a pulp outlet. The juice extractor further comprises a spindle, rotatably mounted in the food processing chamber for transporting food from the food inlet through the food compression section and for transporting pulp through the pulp outlet out of the food compression section, and a pulp pushing section arranged between the pulp outlet and the pulp discharge opening and comprising pushing means arranged to actively push the pulp out of the discharge opening.
