Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional juice extractors face issues with juice being undesirably discharged through small spaces between the feed screw and control parts, leading to suboptimal juice extraction ratios due to the hard cylindrical control part being pushed open, allowing juice to escape alongside residue.
Innovation Solution
A juice extractor design featuring a soft elastic body integrated between the feed screw and control cap, allowing controlled residue discharge through a small ring-shaped space while preventing juice discharge in other areas, with the cylindrical control part integrated into a single body for precise force control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a hard cylindrical control part is used to compress residue, then residue discharge control is improved, but the control part is pushed open by residue pressure, causing juice to leak through peripheral spaces
Solution Approach 1:
The patent replaces the hard cylindrical control part with a soft elastic body that can deform under pressure. This flexible element allows the system to adapt to varying residue pressures without maintaining a rigid structure, preventing juice leakage while enabling controlled residue discharge through the ring-shaped space.
Solution Approach 2:
The patent changes the physical state of the control element from rigid to elastic, allowing it to dynamically adjust its compression force based on residue pressure. This parameter change enables the soft elastic body to maintain sealing effectiveness while accommodating pressure variations during operation.
2Productivity
If the soft elastic body is compressed to discharge residue through a small space, then residue discharge is enabled, but the same compression would prevent juice discharge in other areas
Solution Approach 1:
The patent applies local quality by creating a ring-shaped compression zone that is localized to specific areas. The soft elastic body compresses residue only in the ring-shaped space between its inner and outer circumferential surfaces, while maintaining sealing contact with the housing wall in other areas, thus preventing juice leakage elsewhere.
Solution Approach 2:
The patent segments the compression function into distinct zones: the ring-shaped space for residue discharge and the peripheral contact areas for sealing. This segmentation allows differential functionality where residue can pass through the ring-shaped gap while juice is prevented from leaking at the housing interface.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This design achieves maximum juice extraction ratios for various input materials by deforming the soft elastic body only during residue discharge, preventing juice escape and optimizing residue handling.
Implementation Method 1
a soft elastic body is installed between an end of the feed screw and a cylindrical control part of the control cap through which the residue is discharged, so that the residue discharging force of the juice extractor can be controlled by compressing the surface of the soft elastic body by a rotation of the control cap

AI summary
A juice extractor, which can prevent juice from being easily discharged via a very small part of a space defined between a feed screw and a hard cylindrical control part of a control cap even when residue is being discharged therethrough, thereby realizing the maximum juice extraction ratio for each different kind of input material.
