Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing TATP training baits for canine units in law enforcement suffer from issues such as false positives, false negatives, high manufacturing and transportation costs, requirement for handling before use, and bulky designs that alter the training by sight rather than smell.
Innovation Solution
The use of TATP baits with minimal stabilizers, adsorbed on a cellulosic material support, allowing for direct use without heating, and containing minimal explosive amounts, ensuring safe handling and effective scent detection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If TATP is supplied in aqueous solution to ensure safety and loss of explosive properties, then handling safety is improved, but the bait requires a drying process before use which increases manufacturing complexity and time
Solution Approach 1:
The patent extracts the harmful aqueous solvent from the TATP mixture, leaving only the explosive substance adsorbed on the support material. This is achieved by allowing the aqueous solution to evaporate or evaporate the solvent, leaving the TATP on the support ready for immediate use without requiring complex drying processes.
Solution Approach 2:
The support material is pre-treated or selected to facilitate the removal of aqueous solvent and to maintain TATP in a suitable state for immediate use. The support material's properties are optimized to enable preliminary solvent removal while preserving the explosive's detection capabilities.
2Reliability
If stabilizing additives are added to TATP baits to prevent false positives, then detection reliability is improved, but the presence of these additives causes false positives when dogs detect them
Solution Approach 1:
The patent removes stabilizing additives from the TATP bait composition, using only pure TATP adsorbed on inert support material. This eliminates the source of false positives while maintaining detection reliability through the use of appropriate support materials that do not interfere with the explosive's scent profile.
Solution Approach 2:
The patent employs disposable support materials that are inert and do not leave interfering scents. These single-use supports eliminate the need for complex stabilization mechanisms and prevent false positives, as they are replaced after each use to avoid accumulation of interfering substances.
3Reliability
If diatomaceous earth is used as an absorbent material to contain TATP, then the explosive is contained, but the material requires a housing to contain it which increases device volume and complexity
Solution Approach 1:
The patent uses support materials with specific local properties (porosity, surface area, chemical inertness) that enable direct containment of TATP without requiring external housing. The support material's structure is optimized to hold the explosive while maintaining a compact form factor suitable for training scenarios.
Solution Approach 2:
The support material serves multiple functions simultaneously: it acts as the containment structure, the adsorbent medium, and the scent carrier. This multi-functionality eliminates the need for separate housing components, reducing overall device volume while maintaining reliable explosive containment.
4Reliability
If a gastight closure or permeable device is added to prevent carrier material from escaping, then containment is improved, but production cost and complexity increase
Solution Approach 1:
The patent removes the need for gastight closures and permeable devices by using support materials that physically contain the TATP through adsorption and capillary action. The support material's structure itself provides the containment function, eliminating the need for additional closure mechanisms and simplifying production.
