Solution Overview

Problem

Conventional culture devices face difficulties in decomposing liquefied sterilizing gas that remains in areas where ultraviolet rays do not reach, leading to extended sterilization periods and potential harm to cultures.

Innovation Solution

A sterilizing component removal device that uses a first sprayer to supply a liquid, either promoting gasification or containing active species, in an atomized manner into the working chamber to facilitate the removal of sterilizing components, thereby expelling them more efficiently.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If ultraviolet rays are used to decompose sterilizing gas, then sterilization effectiveness is improved, but liquefied sterilizing gas remains in areas where ultraviolet rays do not reach, extending the sterilization period

Engineering Contradiction:

Improvesterilization effectivenessVSAvoidsterilization period

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The patent introduces a liquid substance as an intermediary that facilitates the decomposition of sterilizing gas. This liquid is supplied in an atomized manner to increase contact surface area, enabling more effective decomposition of sterilizing gas including in areas where ultraviolet rays cannot reach, thus resolving the contradiction between sterilization effectiveness and time consumption

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent changes the physical state and distribution parameters of the decomposition agent by using atomized liquid spray instead of direct ultraviolet irradiation alone. This parameter change allows the decomposition process to occur more uniformly throughout the working chamber, reducing the sterilization period while maintaining effectiveness

Inventive Principle:

Principle #35Parameter changes

2Reliability

If sterilizing gas is sprayed into the working chamber, then sterilization capability is improved, but remaining sterilizing gas causes harmful effects on cultures

Engineering Contradiction:

Improvesterilization capabilityVSAvoidharmful effects on cultures

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent converts the harmful remaining sterilizing gas into a beneficial decomposition process by introducing a liquid substance that reacts with or facilitates the breakdown of the sterilizing gas. The atomized liquid transforms the persistent harmful gas into easily removable decomposition products, eliminating harmful effects on cultures while maintaining sterilization capability

Inventive Principle:

Principle #22Blessing in disguise (Convert harm into benefit)

Solution Approach 2:

The patent implements a process where the sterilizing gas is used for sterilization, then decomposed and removed from the working chamber. The liquid substance aids in breaking down the sterilizing gas into components that can be efficiently expelled, ensuring the chamber is safe for cultures without residual harmful effects

Inventive Principle:

Principle #34Discarding and recovering
