Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If peroxide explosives are used for training and calibration, then detection systems can be validated, but safety risks increase due to high explosiveness and sensitivity
Solution Approach 1:
The patent uses ionic liquids as an intermediary substance to dissolve peroxide explosives, creating a stable solution that maintains the explosive's scent properties for detection validation while eliminating mechanical sensitivity and reducing safety risks during handling and storage
2Duration of action of moving object
If peroxide explosives are dissolved in volatile solvents, then scent sources can be created, but the solvents increase volatility and reduce stability
Solution Approach 1:
The patent changes the physical-chemical parameters of the solvent system by using ionic liquids with negligible vapor pressure instead of volatile organic solvents, thereby achieving both long-lasting scent sources and enhanced solution stability simultaneously
3Object-affected harmful factors
If small amounts of peroxide explosive are used, then safety is improved, but scent source intensity decreases
Solution Approach 1:
The ionic liquid acts as a mediator that allows higher concentrations of peroxide explosive to be safely handled in solution form, maintaining or enhancing scent source intensity while the solution matrix provides safety through reduced mechanical sensitivity
4Measurement precision
If peroxide explosives are mechanically removed for analysis, then identification is achieved, but accidental ignition risk increases
Solution Approach 1:
The patent replaces mechanical removal and handling of explosive materials with analytical techniques that work directly on the ionic liquid solution, eliminating the need for mechanical manipulation that could cause friction or impact-induced ignition
