Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If live hazards such as explosives are used for training, then realistic hazard effects can be experienced, but safety risks and practicality are severely compromised
Solution Approach 1:
The patent uses wireless signals (WiFi networks) as copies to represent hazard effects. Instead of using actual explosives, the system transmits wireless signals that simulate the presence and effects of hazards at different locations. Receivers detect these signals to determine hazard effects, providing a safe yet realistic training experience.
Solution Approach 2:
The patent replaces the mechanical/physical hazard system (explosives, fire, chemicals) with an electromagnetic field-based system (wireless signals). The hazard effects are represented through radio frequency transmissions rather than physical dangerous materials, eliminating safety risks while maintaining simulation capability.
2Adaptability or versatility
If a simulation system is made robust and configurable for field use with multiple hazards, then versatility improves, but device complexity increases
Solution Approach 1:
The patent uses a universal wireless communication infrastructure (WiFi networks) to simulate multiple different hazard types. The same transmitters and receivers can simulate various hazards (explosives, fire, chemical, biological, radiological) by changing the transmitted signals and network identifiers, eliminating the need for separate simulation systems for each hazard type.
Solution Approach 2:
The patent changes parameters of the wireless signal (network identifiers, signal strength, transmission characteristics) to represent different hazard types and effects. By modifying these parameters, the system can simulate multiple hazard scenarios without changing the physical hardware, reducing complexity while maintaining versatility.
