Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional methods for treating cuts and bruises using large plastic bottles of Isopropyl Alcohol Mixture Agent are cumbersome and inefficient, particularly in emergency situations where rapid and portable antiseptic application is needed.
Innovation Solution
An aerosol can with a trigger sprayer system that allows easy, one-handed use of Isopropyl Alcohol Mixture Agent, featuring a tab-activated mechanism for secure storage and rapid dispensing as a mist spray, utilizing a propellant like nitrogen or air to exert pressure on the agent for efficient delivery.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If a large plastic bottle of Isopropyl Alcohol Mixture Agent is used for treating wounds, then the container can hold sufficient antiseptic volume, but the device becomes bulky and cumbersome to use
Solution Approach 1:
The patent transforms the physical state and delivery parameters of the isopropyl alcohol mixture agent from liquid in a bottle to aerosol spray form. This parameter change enables the same quantity of antiseptic to be delivered in a compact, lightweight aerosol can that is easy to hold and transport, directly resolving the contradiction between sufficient antiseptic volume and portability
Solution Approach 2:
The patent employs pneumatic principles by using compressed gas (propellant) to deliver the isopropyl alcohol mixture agent through an aerosol spray mechanism. This allows the antiseptic to be stored under pressure in a compact can and delivered rapidly through controlled spray actuation, achieving both high quantity delivery and ease of operation
2Ease of operation
If a traditional pouring method is used to apply Isopropyl Alcohol Mixture Agent, then the application process is simple, but the treatment speed is slow and inefficient in emergencies
Solution Approach 1:
The patent employs periodic action through the trigger-activated spray mechanism that delivers the isopropyl alcohol mixture agent in controlled bursts or continuous spray streams. This periodic delivery method maintains operational simplicity while dramatically increasing treatment speed compared to manual pouring, allowing rapid application in emergency situations
Solution Approach 2:
The patent changes the delivery parameter from slow pouring to rapid aerosol spray. This parameter transformation maintains ease of operation through simple trigger activation while increasing productivity by delivering the antiseptic much faster, enabling treatment of multiple wounds or multiple patients in succession
3Ease of operation
If the aerosol can is designed for portability and one-handed use, then the device is easy to hold and operate, but the spray mechanism becomes more complex
Solution Approach 1:
The patent applies self-service principles through the automatic trigger mechanism that returns to its resting position after each spray actuation. The trigger assembly automatically resets without requiring manual intervention, allowing continuous one-handed operation while managing the complexity of the spray mechanism through automatic resetting functionality
Solution Approach 2:
The patent employs dynamic design in the trigger assembly that allows movement and automatic resetting. The trigger can be depressed for spray activation and automatically returns to its initial position, enabling flexible one-handed operation. This dynamic mechanism manages complexity through controlled movement rather than fixed complex components
4Reliability
If a tab-activated sealing mechanism is used to prevent tampering, then the storage security is improved, but the initial activation step adds complexity
Solution Approach 1:
The patent applies preliminary action through the pre-attached tab that seals the trigger mechanism before use. This tab must be removed or broken to activate the spray function, providing tamper evidence and storage security. The preliminary sealing action is simple in design but effective in preventing unauthorized activation while maintaining overall device simplicity

Implementation Method 1
There is a Propellant composed of nitrogen, air or mixture thereof inside the can that presses on the Bag that holds the Isopropyl Alcohol Mixture Agent
Implementation Method 2
The Opening on the trigger Assembly can is configured to allow the Isopropyl Alcohol Mixture Agent to flow out as a mist in a spray cone
Implementation Method 3
spray a Isopropyl Alcohol Mixture Agent onto the wound to be treated

AI summary
An Aerosol Isopropyl Alcohol Mixture Agent with Trigger Sprayer that can be easily held in one hand. The Isopropyl Alcohol Mixture Agent is in a bag inside a can and under pressure from air nitrogen, 1,1,1,2-Tetrafluoroethane, Difluoroethane, Petroleum Hydrocarbon, CO2, HFC1234ze, individually or mixture thereof and can only be initially opened and released by pulling the tab of the trigger sprayer. The Trigger Assembly cannot be sprayed until the tab is pulled. The Can is cylindrical canister housing and has a Dip Tube that goes to the bag of the can to the Isopropyl Alcohol Mixture Agent. There is Propellant composed of air nitrogen, 1,1,1,2-Tetrafluoroethane, Difluoroethane, Petroleum Hydrocarbon, CO2, HFC1234ze, individually or mixture thereof in the can that pushes on the bag holding the Isopropyl Alcohol Mixture Agent up through the Dip Tube to the Valve Operative and then to the Actuator Stem up through the Trigger SprayerInitially pulling the tab of the Trigger Assembly allows the Trigger to be pressed and be moved. Once the Tab is pulled it does not ever need to be pulled again for future uses and allows the Trigger Pivoting Member of the Trigger Assembly to press down on the Actuator Stem which then exerts pressure on the Valve Operative which allows the Propellant in the Can to exert pressure on the bag and force the Isopropyl Alcohol Mixture Agent in the bag through the Dip Tube up the Valve Operative through the Chamber Hole into the Direction Chamber with pressure up through the Nozzle out the Opening toward the area to be treated. The user then holds down the trigger and sprays the area to be treated with the Isopropyl Alcohol Mixture Agent which comes out as a mist in a spray cone.
