Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vegetable washers fail to completely remove Group B and Group C impurities, leaving them mixed with vegetables, and have a dead angle issue that compromises cleaning effectiveness, leading to incomplete washing.
Innovation Solution
A vegetable washer with a rotating washing-basket and a central drainage outlet that creates a vortex to separate and discharge impurities, combined with a filter at the basket's port to retain impurities and a funnel-shaped bottom to enhance impurity collection, along with periodic centripetal and centrifugal motion to flip and turn vegetables.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a traditional vegetable washer uses water circulation to wash vegetables, then Group A impurities can be removed, but Group B and Group C impurities remain mixed with vegetables
Solution Approach 1:
The washing process is divided into two distinct functional zones: a washing basket for Group A impurity removal and a sedimentation tank for Group B and Group C impurity separation. This spatial segmentation allows different types of impurities to be removed through different mechanisms, preventing their mixing with vegetables.
Solution Approach 2:
The harmful factor of impurity mixing is eliminated by extracting the sedimentation function from the washing process. A separate sedimentation tank is used to settle and collect Group B and Group C impurities, which are then discharged separately from the washing water, preventing re-contamination of vegetables.
2Productivity
If water flows continuously through the washing basket, then washing efficiency is improved, but dead angles remain where impurities accumulate
Solution Approach 1:
The washing basket is designed to rotate during the washing process, creating dynamic water flow patterns that eliminate dead angles. This rotation ensures all surfaces of vegetables are exposed to washing water, preventing impurity accumulation in stationary zones while maintaining high washing efficiency.
Solution Approach 2:
The washing process employs periodic rotation of the washing basket combined with intermittent water spraying. This periodic action ensures comprehensive coverage of all vegetable surfaces over time, eliminating dead angles without requiring continuous high-speed water flow that would cause erosion.
3Reliability
If impurities are separated from vegetables, then washing quality is improved, but the process becomes complex requiring multiple steps
Solution Approach 1:
The washing basket and sedimentation tank are merged into a single integrated washing machine system. The washing basket is positioned within the sedimentation tank, allowing both functions to operate simultaneously in one device. This merging achieves high washing quality without requiring separate manual processing steps.
Solution Approach 2:
The system automatically separates and discharges different types of impurities through its designed structure. Group A impurities are removed with washing water, while Group B and Group C impurities settle in the sedimentation tank and are discharged separately. This self-service separation mechanism achieves high washing quality without complex manual intervention.
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
The solution effectively separates and removes all impurities, preventing them from re-entering the vegetables and ensuring thorough cleaning without the need for manual intervention, overcoming the limitations of existing technologies.
Implementation Method 1
the water is forced to be flung from inside of the washing-basket to the gap of the basket and bucket by the centrifugal force
Implementation Method 2
A vegetable washer with a rotating washing-basket and a central drainage outlet that creates a vortex to separate and discharge impurities

AI summary
A vegetable washing method capable of separating and splitting impurities and a machine therefor. The method comprises putting fruit and vegetable into a washing basket, then driving the wash basket to rotate by an electric motor so as to force water flow to circulate repeatedly, as a result separating the impurities and the vegetable. The method has the following three technical features of A, B and C, or at least has one of them. A. using a method for preventing the impurities thrown outside the washing basket together with the water from circularly falling into the basket again together with the water to gradually purify the vegetable in the basket; B. using a vortex center draining method to discharge the sewage and impurities; C. using a method for making the vegetable in the washing basket periodically centripetal and centrifugal motion to flip and turn the placement angle of the vegetable in the basket. The vegetable washing method enables the impurities of different specific gravities to split into different spaces, and then to be removed.
