Two-Bag Spray Device for In-Situ Active Oxygen Generation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cleaning agents with bleaching and disinfecting effects often rely on sodium hypochlorite, which is undesirable due to health and environmental concerns, and there is a need for a user-friendly alternative that can generate active oxygen effectively.
Innovation Solution
A spray device with two separate storage bags, where one bag contains a catalyst such as silver nitrate or potassium iodide and the other contains hydrogen peroxide, which are mixed during spraying to form active oxygen, creating an oxygen-based bleach without using hypochlorite or other questionable agents.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If sodium hypochlorite is used for bleaching and disinfecting, then strong cleaning effects are achieved, but health and environmental concerns arise
Solution Approach 1:
The invention changes the chemical composition parameters by replacing sodium hypochlorite with a hydrogen peroxide-based system activated by silver nitrate catalyst, transforming the cleaning agent from chlorine-based to oxygen-based while maintaining effectiveness
Solution Approach 2:
The invention extracts and removes the harmful chlorine component from traditional bleach formulations, using only hydrogen peroxide and silver nitrate to generate active oxygen for cleaning, thereby eliminating health and environmental hazards
2Ease of operation
If active oxygen is generated in situ by mixing catalyst and hydrogen peroxide during spraying, then user-friendly handling is achieved, but device complexity increases
Solution Approach 1:
The invention segments the cleaning solution into two separate components (catalyst solution and hydrogen peroxide solution) stored in individual bags within the spray device, allowing simple mixing during spraying while maintaining ease of use
Solution Approach 2:
The invention prepares the catalyst and hydrogen peroxide separately in advance within the spray device, so that when spraying occurs, the active oxygen is generated immediately upon mixing, combining preparation convenience with operational simplicity
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
This method generates active oxygen rapidly at ambient temperature and slightly alkaline pH, providing a strong oxidizing agent with bleaching and disinfecting effects, forming an oxygen-based cleaner that is effective and safe for use.
Implementation Method 1
the first storage bag contains a spray solution comprising at least one catalyst for releasing oxygen from hydrogen peroxide, selected from silver nitrate or from silver nitrate and also potassium iodide
Implementation Method 2
causes an effective formation of active oxygen when spraying and mixing the first and second spray solutions. According to the invention, active oxygen is formed in a short time and at ambient temperature
Implementation Method 3
active oxygen can be generated in situ and thus cleaning agents with a bleaching and disinfecting effect can be provided
