Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If pyrotechnic composition is used to simulate battlefield events, then realistic simulation effects are achieved, but cost increases and environmental harm occurs
Solution Approach 1:
The patent replaces the pyrotechnic (chemical) system with an acoustic system. A sound reproduction unit plays back audio files containing control signals with signal peaks that trigger simulation events. The acoustic energy from the sound reproduction unit causes a diaphragm to vibrate, and these vibrations trigger optical effects through a transmission means, eliminating the need for harmful pyrotechnic materials while maintaining simulation realism.
Solution Approach 2:
The patent uses audio files that contain recordings of actual battlefield sounds (gunfire, explosions) as control signals. These audio files are processed to include signal peaks that trigger the simulation effects. By copying the acoustic characteristics of real battlefield events and using them to control the simulation, the system achieves realism without using actual pyrotechnics.
2Reliability
If pyrotechnic composition is used to simulate battlefield events, then simulation effects are produced, but risk of injury increases
Solution Approach 1:
The patent replaces the dangerous pyrotechnic system with a safe acoustic system. The sound reproduction unit plays back audio files that contain control signals, and the resulting diaphragm vibrations trigger simulation effects without any explosive or pyrotechnic materials. This substitution eliminates the risk of injury from accidental activation while maintaining simulation effectiveness.
3Reliability
If pyrotechnic composition is used to simulate battlefield events, then simulation effects are achieved, but cost increases
Solution Approach 1:
The patent replaces the expensive pyrotechnic system with a cost-effective acoustic system. The sound reproduction unit, audio files, and electronic control components are significantly cheaper than pyrotechnic materials. The system uses readily available technology (speakers, audio processing, LED lights) to achieve the same simulation capability, dramatically reducing manufacturing and operational costs.
4Object-affected harmful factors
If audio files with control signals are used to trigger simulation events, then safety is improved, but device complexity increases
Solution Approach 1:
The sound reproduction unit serves multiple functions: it reproduces battlefield sounds for realism and simultaneously generates control signals with signal peaks that trigger simulation events. The audio files contain both the acoustic output and the control information, eliminating the need for separate control systems and reducing overall device complexity despite the enhanced safety features.
Solution Approach 2:
The patent merges the sound reproduction function with the control signal generation function. The audio files contain control signals embedded within the battlefield sound recordings, and the sound reproduction unit performs both acoustic output and control signal generation. This merging reduces the number of separate components and simplifies the overall system architecture while maintaining safety.
