Solution Overview
Problem
Existing disinfection technologies lack convenience, durability, and accuracy in visualizing disinfectant applications, especially in large-scale disinfection scenarios, requiring special tools and manual recording, which is time-consuming and prone to errors.
Innovation Solution
A disinfectant visualizing sheet with a chromogenic portion and a silsesquioxane or polyethyleneimine coating that changes color upon disinfectant exposure, allowing easy visual confirmation and long-term storage, and includes a base material with a chromogenic portion and a coating portion to facilitate repeated use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If fluorescent materials in the ultraviolet range are used to visualize disinfection operations, then disinfection visualization is achieved, but special tools are required making it inconvenient
Solution Approach 1:
The patent extracts the visualization function from the disinfectant itself by adding a separate chromogenic component. The chromogenic portion includes a visualizing agent that changes color upon exposure to disinfectant, allowing visualization without requiring external UV lights or special tools. This separates the visualization function from the disinfection function, enabling simple visual observation with the naked eye.
2Measurement precision
If pH-responsive dye is mixed with disinfectant in a single solution for color change, then visualization is achieved, but long-term storage becomes difficult
Solution Approach 1:
The patent segments the system into separate functional components: a base material with chromogenic portion containing the visualizing agent, and a disinfectant solution. The chromogenic portion is disposed on the base material and remains stable during storage. When the disinfectant is applied to the chromogenic portion, the visualizing agent changes color. This segmentation prevents premature reactions and enables long-term storage of both components separately.
3Measurement precision
If detection species in aerogel is used to induce color change, then visualization is achieved, but durability for repeated use is lacking
Solution Approach 1:
The patent uses a composite structure consisting of a base material (such as paper or fabric) with a chromogenic portion disposed on it. The chromogenic portion contains a visualizing agent that is chemically stable and can undergo reversible or irreversible color changes. This composite structure provides mechanical durability for repeated handling and use, while the visualizing agent maintains its responsiveness to disinfectant exposure over multiple cycles.
4Loss of information
If manual recording of disinfectant applications is performed for large number of disinfection targets, then record keeping is achieved, but it is time-consuming and prone to errors
Solution Approach 1:
The patent enables the disinfection process to self-record its own status through the visual color change of the chromogenic portion. When disinfectant is applied, the visualizing agent automatically changes color to indicate successful application. This eliminates the need for manual recording by personnel, as the visualization itself serves as the record. Multiple targets can be quickly assessed by visual inspection, dramatically reducing time and error rates associated with manual documentation.
