Solution Overview

Problem

Conventional chlorine dioxide generators are not portable and suffer from liquid dripping or spill issues, and achieving high concentrations of chlorine dioxide gas requires hazardous acidic substances, which poses handling risks and reduces generation efficiency.

Innovation Solution

A deformable container with a gas-permeable, water-impermeable gas discharge port and a non-contact arrangement of solid acidic and chlorite solutions, where the enclosure breaks upon deformation to generate chlorine dioxide gas, allowing for safe portability and efficient generation with low acidic substance concentrations.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Volume of moving object

If the device is formed compact for providing portability, then portability is improved, but liquid dripping or spill occurs from inside the device

Engineering Contradiction:
Improvedevice sizeVSAvoidliquid containment
Core Design Contradiction:
Volume of moving objectVSReliability

Solution Approach 1:

The device is divided into separate compartments: a reaction chamber for generating chlorine dioxide gas and a storage chamber for liquid chlorine. This segmentation prevents liquid from reaching areas where it could drip or spill, while maintaining compact overall device size for portability.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

A gas-permeable, liquid-impermeable membrane is introduced as an intermediary barrier between the liquid chlorine storage and the reaction chamber. This membrane allows chlorine gas to pass through for reaction while blocking liquid chlorine, preventing liquid leakage while enabling the compact design.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If sealing of the container is ensured to prevent liquid dripping or spill, then liquid containment is improved, but resistance in discharging of chlorine dioxide gas increases

Engineering Contradiction:
Improveliquid containmentVSAvoidgas discharge efficiency
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The container structure has different properties in different locations: the gas discharge port is made gas-permeable while the rest of the container walls are liquid-tight. This local differentiation allows efficient gas discharge through the permeable port while maintaining liquid containment through the impermeable sealing of the rest of the container.

Inventive Principle:
Principle #3Local quality

3Productivity

If the concentration of acidic substance is increased to achieve high concentration of chlorine dioxide gas, then generation efficiency is improved, but handling safety deteriorates due to hazardous substance

Engineering Contradiction:
Improvechlorine dioxide generation efficiencyVSAvoidhandling safety
Core Design Contradiction:
ProductivityVSObject-affected harmful factors

Solution Approach 1:

The invention changes the concentration parameter of the acidic substance from high to low (e.g., using dilute sulfuric acid instead of concentrated acid). This parameter change maintains sufficient chlorine dioxide generation efficiency while dramatically improving handling safety by reducing the hazards associated with concentrated acidic substances.

Inventive Principle:
Principle #35Parameter changes

AI summary

A method of producing chlorine dioxide involves generating chlorine dioxide gas by deforming a container body of a chlorine dioxide generator which is deformable in response to application of a force to the container body from outside of the container body. The deforming of the container body causes an enclosure contained in the cylinder body to be broken to bring an aqueous chlorite solution into contact with a solid acidic composition to generate chlorine dioxide gas that is discharged via a gas discharge port of the container body to outside of the container body. The method additionally involves submerging in water at least the gas discharge port of the container body during the generation of the chlorine dioxide gas to dissolve the chlorine dioxide gas discharged via the gas discharge port in the water.
