Backpack Pressure Tank Dispensing Lubric Gel Defense
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing personal defense sprays, such as pepper spray and tear gas, are not viable for all individuals due to accessibility issues, regulatory bans, and ineffectiveness in certain populations, and they often require close proximity to the assailant, limiting escape time and causing potential harm.
Innovation Solution
A pressurized backpack system dispensing a biodegradable, non-toxic, lubric gel composition that temporarily impairs vision and can be applied preemptively, increasing escape time without causing long-term damage or pain, featuring a fatty acid, thickening agent, detergent, surfactant, and water, optionally with a malodorant, and designed for controlled dispensing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If pepper spray and tear gas are used for personal defense, then assailants can be disabled through eye irritation, but these sprays are banned or heavily regulated in many locations and require close proximity to be effective
Solution Approach 1:
The patent extracts the active irritating agent from the traditional pepper spray formulation and replaces it with a biodegradable, non-toxic alternative composed of natural ingredients like fatty acids and plant extracts. This extraction allows the device to achieve eye irritation effects without containing regulated substances, thereby resolving the legal accessibility issue while maintaining operational effectiveness at extended ranges
Solution Approach 2:
The patent changes the chemical parameters of the spray composition by using a water-based formulation with natural irritants instead of oleoresin capsicum. This parameter change enables the spray to be classified as a non-weapon in many jurisdictions while maintaining the ability to temporarily impair vision and disable assailants at greater distances
2Reliability
If pepper spray is used to disable assailants, then vision can be impaired, but it causes pain or stinging and has negative respiratory issues for some populations
Solution Approach 1:
The patent modifies the chemical composition parameters by replacing synthetic irritants with natural, biodegradable ingredients such as fatty acids, plant extracts, and surfactants. This composition change maintains the vision-impairing effect while eliminating or reducing pain, stinging, and respiratory harm, making it safe for broader population use including those with respiratory conditions
Solution Approach 2:
The patent applies different functional components to specific targets: the formulation is designed to preferentially affect the eyes through localized irritation while minimizing impact on respiratory systems. The natural ingredients are selected to provide targeted visual impairment without the systemic respiratory effects associated with traditional tear gas and pepper spray
3Reliability
If traditional personal defense sprays are used, then assailants can be disabled, but they cause long-term damage or pain to the eyes
Solution Approach 1:
The patent changes the temporal and chemical parameters of the irritant effect by using naturally degradable ingredients that lose their irritating properties over time. The formulation is designed to provide temporary vision impairment for assailant disablement while automatically reducing to harmless levels, preventing long-term eye damage and persistent pain associated with conventional sprays
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 system effectively delays an assailant by creating a slick surface and temporary eye irritation without long-term harm, providing a non-lethal, environmentally friendly, and easily washable defense mechanism that increases escape time and is accessible to a broader population.
Implementation Method 1
a pumpless pressure tank for storing and discharging under pressure a personal defense material
Implementation Method 2
A hose is connected to the flow connector for allowing controlled dispensing flow of the material from the pressure tank under pressure
Implementation Method 3
a personal defense material, which may be a lubric gel composition for personal defense

AI summary
A backpack material dispenser that includes a pumpless pressure tank for storing and discharging a material under pressure contained in the pressure tank and a hose and a shut off valve connected to an output opening of the pressure tank for allowing flow of the material from the pressure tank under pressure and through a nozzle communicating with a discharge end of the hose. A discharge valve communicates with the nozzle proximate the hose for allowing controlled discharge of the material from the nozzle. A backpack assembly mounts the pressure tank for being carried by a user. A charging tank contains a gas under pressure to charge the pressure tank to a predetermined pressure, and a releasable connector of the charging tank attaches to a complementary connector of the pressure tank for charging the pressure tank with the gas under pressure to the suitable pressure tank pressure.
