Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a plurality of ultrasonic transmitters are used in mist circulation dispersion means, then decontamination effectiveness is improved, but operation confirmation becomes difficult

Engineering Contradiction:

Improvedecontamination effectivenessVSAvoidoperation confirmation

Core Design Contradiction:

ReliabilityVSDifficulty of detecting and measuring

Solution Approach 1:

The patent introduces an operation confirmation mechanism that provides feedback on the operational status of each ultrasonic transmitter. This allows the system to monitor whether each transmitter is functioning properly, resolving the difficulty of detecting and measuring the operation of multiple transmitters while maintaining decontamination effectiveness.

Inventive Principle:

Principle #23Feedback

2Reliability

If excessive amounts of hydrogen peroxide are supplied to thicken condensed film, then decontamination effect is improved, but corrosion to equipment and wall surfaces increases

Engineering Contradiction:

Improvedecontamination effectVSAvoidcorrosion

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent applies ultrasonic vibration to the hydrogen peroxide condensed film to enhance decontamination effectiveness without requiring excessive amounts of hydrogen peroxide. The ultrasonic action partially breaks down the condensed film structure, allowing effective decontamination with reduced concentrations, thereby minimizing corrosion to equipment and wall surfaces.

Inventive Principle:

Principle #16Partial or excessive action

3Reliability

If excessive amounts of hydrogen peroxide are supplied, then decontamination effect is improved, but aeration duration increases

Engineering Contradiction:

Improvedecontamination effectVSAvoidaeration duration

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

By using ultrasonic vibration to enhance the decontamination effect of hydrogen peroxide, the system achieves effective decontamination with reduced amounts of chemical agent. This reduces the load on the aeration system, thereby shortening the required aeration duration while maintaining decontamination effectiveness.

Inventive Principle:

Principle #16Partial or excessive action

AI summary

A decontamination device capable of confirming accurate operations of a mist circulation dispersion means before and after or during a decontamination operation and guaranteeing the overall operation as a decontamination device.The device includes a mist supply means, a mist circulation dispersion means, and an ultrasonic detection means. The mist supply means converts a chemical for decontamination of the inside of a working chamber of the device into a mist for decontamination and supplies such mist to the inside of the working chamber. The mist circulation dispersion means subjects a vibrating board (which includes a plurality of ultrasonic transmitters) to ultrasonic vibration to generate sound flows with ultrasound from board surfaces in the vertical direction and presses the mist with acoustic radiation pressure of the sound flows in order to circulate and disperse the mist for decontamination in the working chamber. The ultrasonic detection means includes an ultrasonic receiver configured to detect the operation of the plurality of ultrasonic transmitters included in the vibrating board in as a whole and/or the operation of each of the constituent ultrasonic transmitters.
