Solution Overview

Problem

Existing fruit and vegetable washing devices lack a design that allows for effective rinsing, draining, and storing while maintaining visibility and ease of use, particularly in retaining fruits and vegetables within the device during the rinsing process.

Innovation Solution

A cup with integrated viewing windows, a removable screen for draining, and a lid with a drain spout and cap that enables efficient rinsing and draining while keeping fruits or vegetables contained, allowing for visibility and easy handling.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of energy

If a lid with drain spout is used to drain water, then water drainage is improved, but fruits and vegetables may fall through the drain opening

Engineering Contradiction:

Improvewater drainage efficiencyVSAvoidretention of fruits and vegetables

Core Design Contradiction:

Loss of energyVSReliability

Solution Approach 1:

The patent employs a screen made of porous or perforated material that covers the drain opening. This screen allows water to pass through while blocking fruits and vegetables, effectively resolving the contradiction between drainage efficiency and retention reliability.

Inventive Principle:

Principle #31Porous materials

2Ease of manufacture

If the cup is made opaque for durability, then manufacturing is easier, but visibility of fruits and vegetables is reduced

Engineering Contradiction:

Improvecup manufacturing simplicityVSAvoidvisibility of contents

Core Design Contradiction:

Ease of manufactureVSIllumination intensity

Solution Approach 1:

The patent applies local quality by making specific portions of the cup (viewing windows) transparent while the rest remains opaque. This allows the cup to maintain overall durability while providing localized visibility of the contents.

Inventive Principle:

Principle #3Local quality

3Quantity of substance

If a screen is added for draining, then water retention during rinsing is improved, but device complexity increases

Engineering Contradiction:

Improvewater retention in cupVSAvoidnumber of components

Core Design Contradiction:

Quantity of substanceVSDevice complexity

Solution Approach 1:

The screen serves multiple functions: it acts as a filter to prevent fruits and vegetables from falling through, a support structure for the lid, and a drainage control mechanism. This multi-functionality reduces the need for additional separate components.

Inventive Principle:

Principle #6Universality (Multi-functionality)

4Ease of manufacture

If the drain spout cap is fixed, then manufacturing is simpler, but ease of operation for opening/closing is reduced

Engineering Contradiction:

Improvecap attachment simplicityVSAvoidcap opening and closing

Core Design Contradiction:

Ease of manufactureVSEase of operation

Solution Approach 1:

The patent transitions from a fixed cap to a movable cap that can be opened and closed. This dynamic element allows easy control of water drainage while maintaining relatively simple manufacturing through common hinge mechanisms.

Inventive Principle:

Principle #15Dynamics

AI summary

A fruit and vegetable washing device includes a cup comprised of a fluid impermeable material to contain fruits or vegetables and water for rinsing the fruits or vegetables. A pair of viewing windows is each is integrated into the cup to enable the fruits or vegetables to be visible in the cup. A screen is removably positionable into the cup to enable the water to be drained from the cup while retaining the fruits or vegetables within the cup. A lid is removably attachable to the cup to inhibit the water and the fruits or vegetables from passing through the lid. A drain spout is integrated into the lid to enable the water to be drained through the drain spout when the cup is inverted. A cap is movably attached to the drain spout for opening or closing the drain spout.
