Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing chlorine dioxide slow-release agents in refrigerators have unpredictable service lives due to varying temperature and humidity, making it difficult for users to determine when they need replacement, and the gas concentration is often too low for easy detection.
Innovation Solution
A volatilization device with a color-changing member, such as gelatin, that changes color in response to chlorine dioxide gas concentration, allowing users to visually assess the agent's effectiveness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a chlorine dioxide slow-release agent is used in a refrigerator, then sterilization and deodorization effects are achieved, but the service life becomes unpredictable and difficult to monitor
Solution Approach 1:
The patent applies a color-changing member (such as pH-sensitive indicator paper or color-changing gelatin) that changes color in response to chlorine dioxide gas concentration. This allows users to visually monitor the service life of the slow-release agent by observing color transitions, transforming an invisible chemical process into a visible indicator system.
Solution Approach 2:
The color-changing member acts as an intermediary between the chlorine dioxide gas and the user. Instead of directly measuring gas concentration or service life, the intermediary translates chemical changes into visual signals that are easy to observe and interpret.
2Productivity
If the chlorine dioxide slow-release agent releases gas faster at higher temperature and humidity, then sterilization effectiveness improves, but the service life shortens and becomes unpredictable
Solution Approach 1:
The color-changing member provides real-time feedback about the gas release status and remaining service life. As the slow-release agent releases chlorine dioxide gas at varying rates due to temperature and humidity changes, the color-changing member continuously reflects the cumulative gas release, allowing users to monitor the actual service life consumption rather than relying on fixed time predictions.
3Object-affected harmful factors
If the concentration of chlorine dioxide gas is low under normal conditions, then safety is improved, but user detection capability deteriorates
Solution Approach 1:
The patent uses a color-changing member that undergoes visible color transitions when exposed to chlorine dioxide gas, even at low concentrations. This transforms the invisible gas presence into a visible color signal, enabling users to easily detect gas release without requiring specialized equipment or high gas concentrations.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables timely replacement of chlorine dioxide slow-release agents by visually observing color changes, ensuring consistent food safety and hygiene in refrigerators.
Implementation Method 1
a color-changing member, fixed to the housing, where a side of the color-changing member is exposed to the cavity, another side of the color-changing member is visible from an outer wall of the housing, and the color-changing member changes color according to a concentration of a target gas in the cavity
Implementation Method 2
Chlorine dioxide slow-release agent absorbs water in air through the vent holes, and then produces chlorine dioxide gas
Implementation Method 3
Chlorine dioxide slow-release agent absorbs water in air through the vent holes, and then produces chlorine dioxide gas

AI summary
A volatilization device and a storage device. The volatilization device comprises: a shell (100) having a cavity, an air outlet (301) communicated with the cavity being formed on the shell (100); and a color change member (800) fixed on the shell (100). One side of the color change member (800) is exposed to the cavity, the other side of the color change member (800) can be seen from the outer wall of the shell (100), and the color change member (800) changes color according to the concentration of a target gas in the cavity. The storage device comprises a box (400) and the volatilization device, and the shell (100) is fixed in the box (400). The color change member (800) is fixed on the shell (100), one side of the color change member (800) is exposed to the cavity of the shell (100), the other side of the color change member (800) can be seen from the outer wall of the shell (100), and a user thus can determine, by observing the color change of the color change member (800), the validity of an item to be stored in the cavity, helping the user in in-time replacing.
