Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If wireless independent tracking system is integrated with weapon simulator, then training safety and cost-effectiveness are improved, but device complexity increases
Solution Approach 1:
The tracking system is divided into independent modules: WITS module with tag, shot detector, shot counter, transmitter, and coupler. Each component performs a specific function and can be independently configured or replaced, reducing overall system complexity while maintaining safety benefits
Solution Approach 2:
The WITS module integrates multiple functions into a single device: tracking (tags), shot detection (sensor), ammunition counting (shot counter), and communication (transmitter). This multi-functionality reduces the number of separate components needed, thereby reducing device complexity while improving training safety
2Measurement precision
If motion tracking system tracks active tags to determine gun position and orientation, then measurement precision is improved, but device complexity increases
Solution Approach 1:
The patent replaces complex mechanical tracking systems with optical tracking using infrared active tags and cameras. The tags emit infrared light that is detected by cameras, providing precise 6DOF tracking without mechanical components, thereby improving measurement precision while reducing device complexity
Solution Approach 2:
The active tags use infrared light emission (a form of electromagnetic radiation change) to provide tracking signals. The tags blink in predefined patterns that are identifiable by cameras, enabling distinction between multiple tracked guns and improving position and orientation measurement precision
3Measurement precision
If shot detector uses sensor to detect slide motion speed, then measurement precision is improved, but device complexity increases
Solution Approach 1:
The shot detector utilizes the weapon simulator's own slide motion as the detection mechanism. The sensor detects the speed of slide movement, which naturally occurs during firing, eliminating the need for separate test mechanisms or additional complexity while improving shot detection accuracy
4Loss of information
If transmitter sends signals to smart magazine when out of ammunition, then information completeness is improved, but device complexity increases
Solution Approach 1:
The shot counter continuously monitors ammunition consumption and provides feedback to the transmitter. When the gun is out of virtual ammunition, the transmitter automatically sends a signal to the smart magazine. This closed-loop feedback system ensures complete ammunition status information without requiring complex manual monitoring systems
