Dual-Chamber Spray Cleaner for Stable Oxidizer Mixing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cleaning compositions with oxidizing agents deteriorate quickly when stored together, leading to reduced effectiveness and potential pressure buildup, which can cause the container to buckle or burst, necessitating separate storage and mixing upon application.
Innovation Solution
A manual spray cleaner with two separate chambers and a single dispensing outlet, where one chamber contains a fabric/carpet cleaning composition and the other an oxidizing composition, which are mixed simultaneously upon dispensing, using aerosol propulsion or mechanical means, with components made from corrosion-resistant materials and inert coatings to prevent reaction-induced pressure issues.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If oxidizing agent and activator are stored together in a single chamber, then the cleaning composition is ready for immediate use, but the oxidizing agent deteriorates quickly and pressure builds up causing the container to buckle or burst
Solution Approach 1:
The cleaning system is divided into two separate chambers: one containing the oxidizing agent and another containing the activator. This segmentation prevents premature reaction between the oxidizing agent and activator, maintaining stability during storage while enabling immediate use when the components are mixed at the point of application through the dispensing mechanism.
2Reliability
If oxidizing agent and activator are stored separately in two chambers, then the oxidizing agent remains stable, but the device complexity increases
Solution Approach 1:
Two separate chambers containing the oxidizing agent and activator are merged into a single dispensing system with a common outlet. The chambers are positioned adjacent to each other and connected to a shared dispensing mechanism, allowing simultaneous delivery of both components through a single nozzle while maintaining their separate storage compartments.
3Reliability
If two-component cleaning compositions are mixed upon spraying onto surface, then cleaning effectiveness is maintained, but the application process becomes more complex
Solution Approach 1:
The system automatically mixes the oxidizing agent and activator components as they are dispensed from their respective chambers through the single dispensing outlet. The mixing occurs automatically during the spraying process itself, eliminating the need for separate mixing steps and maintaining cleaning effectiveness while keeping the application process simple and user-friendly.
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
The solution maintains the effectiveness of the oxidizing agent throughout storage and allows for efficient delivery to surfaces, effectively treating various stains on carpets and fabrics while preventing pressure buildup, ensuring safe and effective cleaning.
Implementation Method 1
The compositions can be aerosol propelled or drawn from their respective chambers by a mechanical means such as a pump
Implementation Method 2
the other chamber contains an oxidizing composition that enhances the cleanability of the fabric/carpet cleaning composition

AI summary
A manual spray cleaner for removing dirt and stains from fabrics and carpets comprising a spray bottle having two separate chambers and a single dispensing spray outlet for dispensing controlled amounts of liquids from each of the chambers. One of the chambers has a fabric/carpet cleaning composition therein and the other chamber has an oxidizing composition that enhances the cleanability of the fabric/carpet cleaning composition. The fabric/carpet cleaning composition and the oxidizing composition are simultaneously drawn from their respective chambers and mixed together at the time that they are dispensed from the spray bottle. At least one of the oxidizing composition and the fabric/carpet cleaning composition includes a fabric/carpet protectant. The two compositions are mixed before or after they are sprayed from the bottle. The two compositions can be pressurized with an aerosol propellant or drawn from their respective chambers by a mechanical pump.
