Solution Overview
Problem
Existing odor samples for training explosive detection dogs using peroxidic explosives are hazardous due to their mechanical and thermal sensitivity, and pose challenges in handling and safety, while also being difficult to deactivate and separate from the solvent.
Innovation Solution
A solution of a non-peroxidic explosive in an ionic liquid, where the explosive is desensitized and stabilized, reducing hazards and allowing for safe handling and storage, with a concentration of up to 15% by weight, and an ionic liquid that is non-flammable and non-explosive, making it suitable for training dogs without the risk of explosion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If peroxide explosives are used as odor samples for training explosive detection dogs, then the dogs can be trained to detect explosive odors, but the samples are hazardous due to mechanical and thermal sensitivity and pose handling and safety challenges
Solution Approach 1:
The patent uses ionic liquids as an intermediary medium to dissolve non-peroxide explosives. The ionic liquid acts as a safe carrier that maintains the explosive's odor properties for dog training while eliminating the hazardous mechanical and thermal sensitivity associated with peroxide explosives. This intermediary solution allows handling and storage without special safety precautions.
Solution Approach 2:
The patent changes the chemical parameter by substituting peroxide explosives with non-peroxide explosives (such as TNT, RDX, HMX) dissolved in ionic liquids. This parameter change maintains the essential odor detection function while fundamentally altering the safety profile by eliminating the explosive's mechanical and thermal sensitivity.
2Object-affected harmful factors
If peroxide explosives are dissolved in ionic liquids to reduce sensitivity, then handling safety is improved, but the explosives can be separated from the ionic liquid requiring additional deactivation steps
Solution Approach 1:
The patent converts the potential harm of explosive separation into a benefit by using ionic liquids with specific properties. The ionic liquid's strong solvation power and the explosive's complete desensitization mean that even if separation occurs, the explosive cannot be easily recovered in a hazardous form, turning a potential risk into an additional safety feature.
3Reliability
If non-peroxide explosives are dissolved in ionic liquids at high concentrations, then the scent source is more effective for dog training, but the handling and transportation regulations become more restrictive
Solution Approach 1:
The patent changes the chemical composition parameter by using non-peroxide explosives instead of peroxide explosives. This fundamental parameter change allows the solution to be classified under different hazard categories, enabling high-concentration formulations that are effective for training while avoiding the restrictive handling and transportation regulations applicable to peroxide explosives.
4Reliability
If the explosive concentration in the ionic liquid is increased to improve scent detectability, then the training effectiveness is enhanced, but the risk of misuse to obtain explosive increases
Solution Approach 1:
The ionic liquid serves as a secure intermediary that binds the explosive molecules. The strong interaction between the ionic liquid and explosive prevents easy separation or extraction, thereby reducing misuse risk even at high concentrations. The ionic liquid matrix acts as a protective barrier that maintains both high detection sensitivity and low misuse potential.
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 provides a safe and effective scent source for explosive detection dogs, reducing the risk of explosion and misuse, as the non-peroxidic explosive is completely desensitized, and the ionic liquid does not affect the detectable vapor of the explosive, allowing for long-term use and secure handling.
Implementation Method 1
Dissolving the explosive in the ionic liquid completely desensitizes it to friction, impact, shock, fire, and any other stress
Implementation Method 2
A further advantage of the lipophilic ionic liquid is its relatively low absorption of water from the environment. Water can reduce the shelf life of the odor sample according to the invention, especially with a hydrolysis-sensitive, non-peroxide explosive
Implementation Method 3
The ionic liquid itself has no inherent odor, since the vapor pressure of ionic liquids is negligibly low. The explosive detection dogs can therefore perceive the pure odor of the explosive
