Solution Overview
Problem
Existing real-fuel test bodies for training explosive detection dogs have limited durability and volatility, leading to short usage periods and safety concerns due to explosive fragrances escaping and potential detonation risks.
Innovation Solution
A real-fuel testing body with a solid or liquid carrier material, such as silica or ionic liquid, housed in a gas-tight container with a reversible closure, preventing explosive fragrance escape and ensuring the explosive is non-detonative, thus allowing for extended and safe repeated use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of moving object
If the explosive is contained in a volatile carrier material (e.g., metal foam), then the scent trail is readily released for detection, but the usage duration is limited due to rapid evaporation of the odorant
Solution Approach 1:
The patent changes the physical state and volatility parameters of the carrier material by using an ionic liquid instead of traditional volatile carriers like metal foam. Ionic liquids have negligible vapor pressure, which fundamentally alters the release kinetics of the explosive odorant, enabling controlled, long-term release without rapid evaporation.
Solution Approach 2:
The patent creates a sealed environment containing the explosive-ionic liquid mixture, isolating it from the external atmosphere. This prevents uncontrolled evaporation and allows the system to maintain its integrity over extended periods, with odorant release occurring only when intentionally activated.
2Reliability
If the explosive concentration in the carrier material is high enough for detection, then the scent trail is sufficient for dog detection, but the detonation risk increases
Solution Approach 1:
The patent changes the chemical and physical parameters of the explosive formulation by dissolving it in an ionic liquid. This creates a solution where the explosive molecules are solvated and stabilized, significantly reducing their sensitivity to friction, impact, and heat while maintaining sufficient vapor pressure for detection by trained dogs.
Solution Approach 2:
The ionic liquid acts as an intermediary medium between the explosive and the environment. It serves as both a solvent that stabilizes the explosive and a carrier that controls the release of odorant molecules, thereby decoupling the detection function from the detonation risk.
3Productivity
If the housing is opened for repeated use, then the test body can be used multiple times, but the explosive odorant escapes when not in use
Solution Approach 1:
The patent employs a sealed housing that maintains an inert, controlled environment around the explosive-ionic liquid mixture. This prevents odorant escape during storage and transport, while the system can be opened on demand for training sessions, enabling repeated use without significant loss of explosive material.
