Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems for simulating projectile hits in training areas face challenges in accurately determining hit points due to the rectilinear nature of light pulses, requiring costly reflectors or excessive GPS data transmission, and are prone to errors from atmospheric and directional instability.
Innovation Solution
A system with synchronized clocks for each player, allowing light pulses to be transmitted at predetermined reference times, enabling the second player to calculate distance using the speed of light and time differences, thereby reducing the number of pulses needed and enhancing accuracy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If reflectors are arranged on targets to reflect light pulses back for distance calculation, then the distance measurement accuracy is improved, but the system cost increases significantly
Solution Approach 1:
The invention extracts the reflector component from the target and relocates it to the light pulse transmitter. Instead of placing reflectors on expensive military targets, the system uses integrated reflectors within the transmitter device itself, eliminating the need for separate target reflectors and significantly reducing system cost while maintaining measurement accuracy
Solution Approach 2:
The transmitter device serves dual functions: it both transmits light pulses and contains reflectors to receive reflections. This self-service approach eliminates the need for separate target equipment with reflectors, as the transmitter itself provides the reflection capability needed for distance calculation
2Measurement precision
If GPS data and player information are transmitted instantly to determine impact position, then the hit point determination accuracy is improved, but the number of light pulses required increases significantly
Solution Approach 1:
The invention extracts the position information requirement from the light pulse data stream and obtains it through alternative means (GPS coordinates transmitted separately or pre-stored information). This allows distance calculation to rely solely on time-of-flight measurements from minimal light pulses rather than requiring multiple pulses carrying comprehensive position data
Solution Approach 2:
The system combines distance measurement functionality with minimal light pulse transmission. By using synchronized clocks and time-of-flight calculation, the system achieves accurate hit point determination with far fewer light pulses than would be required to transmit all necessary position and trajectory data through light pulses alone
3Reliability
If multiple light pulses are transmitted to ensure error-free data transmission, then the reliability of information transmission is improved, but the transmission time increases
Solution Approach 1:
The invention replaces redundant light pulse transmissions with electronic clock synchronization and time-stamping mechanisms. Instead of sending multiple identical light pulses to ensure reliable data delivery, the system uses precisely synchronized clocks at transmitter and receiver to accurately determine transmission timing, achieving reliability through temporal precision rather than repetition
Solution Approach 2:
The system performs preliminary clock synchronization before actual distance measurement or data transmission. By pre-synchronizing the clocks of transmitters and receivers, the system establishes a common time reference that enables accurate time-of-flight calculation from minimal light pulses, eliminating the need for multiple redundant transmissions
