Solution Overview

Problem

Conventional chlorine dioxide gas generation methods are ineffective at maintaining sterilization, disinfection, and deodorization effects over a wide area due to the gas dissipating, and the initial high generation of chlorine dioxide makes them unsuitable for carrying.

Innovation Solution

A chlorine dioxide gas generating agent pack containing a mixture of chlorite powder, gas generation control agent powder, moisture-absorbent powder, water-absorbent resin powder, and activating agent powder, housed in a gas-permeable film container that allows gradual generation and release of chlorine dioxide gas in response to humidity, ensuring continuous availability.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If conventional chlorine dioxide gas generation methods are used, then chlorine dioxide gas is generated quickly, but the gas dissipates rapidly and cannot maintain sterilization, disinfection, and deodorization effects over a wide area

Engineering Contradiction:

Improvechlorine dioxide gas generation speedVSAvoidsterilization and disinfection effect duration

Core Design Contradiction:

ProductivityVSDuration of action of stationary object

Solution Approach 1:

The patent incorporates a water-absorbent resin that preliminarily absorbs water from the environment through capillary action, creating a controlled water supply system that enables sustained chlorine dioxide generation over time rather than immediate rapid generation followed by dissipation

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent creates a continuous chlorine dioxide generation system by combining chlorite powder with a water supply mechanism through water-absorbent resin and porous material, allowing the reaction to proceed continuously as water is gradually absorbed and reacted, rather than in a single rapid burst

Inventive Principle:

Principle #20Continuity of useful action

2Quantity of substance

If dissolved chlorine dioxide gas and chlorite are reacted with pH adjuster or activating agent, then chlorine dioxide gas is generated in large amount at the beginning, but this makes the gas unsuitable for being carried

Engineering Contradiction:

Improvechlorine dioxide gas amountVSAvoidportability and suitability for carrying

Core Design Contradiction:

Quantity of substanceVSEase of operation

Solution Approach 1:

The patent uses water-absorbent resin to preliminarily absorb water from the environment before the chlorine dioxide generation reaction occurs, creating a controlled water supply that prevents excessive initial gas generation and enables portable use

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent employs porous material that allows controlled water absorption and gas passage, enabling the chlorine dioxide gas to be generated gradually in controlled amounts suitable for carrying, rather than in large uncontrolled quantities

Inventive Principle:

Principle #31Porous materials

3Area of stationary object

If chlorine dioxide gas is generated using conventional methods, then the sterilization effect is demonstrated over a wide region initially, but the effect diminishes as the gas travels away from the generation position

Engineering Contradiction:

Improvesterilization effect coverage areaVSAvoidsterilization effect consistency

Core Design Contradiction:

Area of stationary objectVSReliability

Solution Approach 1:

The patent creates a continuous chlorine dioxide generation system that maintains constant gas production over time, ensuring that the sterilization effect is reliably maintained in the surrounding area rather than diminishing as with conventional one-time generation methods

Inventive Principle:

Principle #20Continuity of useful action

Solution Approach 2:

The patent uses water-absorbent resin that automatically absorbs water from the environment and triggers the chlorine dioxide generation reaction without external intervention, providing self-sustaining sterilization effect in the surrounding area

Inventive Principle:

Principle #25Self-service
