Indoor Outdoor Adaptive Simulation System for Military Training
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Simulation systems for military combat exercises in areas with buildings face issues such as signal ricochet and wide beam widths, leading to erroneous hit detection when using laser pulse generators, especially at short distances and when soldiers are indoors or outdoors.
Innovation Solution
Adapting transmitters and detecting means to sense their location indoors or outdoors, emitting signals of normal power for outdoor-to-indoor shots and reduced power for indoor shots, with coded signals to differentiate and prevent false hits from ricochets, and incorporating a central network for data communication and injury assessment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the power of laser pulses is reduced or detecting means sensitivity is lowered to prevent false hits from ricochets, then false positive detection is reduced, but soldiers located indoors cannot be detected when shot at by soldiers located outdoors
Solution Approach 1:
The patent applies local quality by differentiating detection sensitivity based on location. Soldiers indoors use detecting means with reduced sensitivity to ignore ricochet signals, while soldiers outdoors use detecting means with normal sensitivity to detect both direct and ricochet shots. This location-based differentiation resolves the contradiction between preventing false positives and maintaining detection capability.
Solution Approach 2:
The patent changes the sensitivity parameter of detecting means based on the soldier's location. Indoor detecting means operate at a first sensitivity level that filters out ricochet signals, while outdoor detecting means operate at a second, higher sensitivity level that detects all shots. This dynamic parameter adjustment resolves the technical contradiction.
2Measurement precision
If laser pulse generators are designed for accurate shooting at larger distances, then long-range accuracy is improved, but short-distance combat effectiveness deteriorates due to excessive beam width and side lobes causing false hits
Solution Approach 1:
The patent applies local quality by implementing location-dependent detection modes. When a soldier is detected indoors, the system switches to a mode that ignores ricochet signals, effectively adapting the detection characteristics to the local combat environment. This resolves the contradiction between long-range accuracy and short-range reliability.
Solution Approach 2:
The patent makes the detection system dynamic by automatically adjusting its sensitivity and hit determination criteria based on the detected location of the target soldier. The system transitions between different operational modes (indoor/outdoor) depending on real-time conditions, allowing it to optimize performance for the specific combat scenario.
3Reliability
If transmitters and detecting means are adapted to sense location and emit coded signals to differentiate indoor and outdoor shots, then false positives from ricochets are eliminated, but device complexity increases
Solution Approach 1:
The patent applies universality by designing a multi-functional detection system that can operate in multiple modes (indoor and outdoor detection) using a single detecting means. The system universally handles both direct shots and ricochet shots by adjusting its interpretation based on location data, reducing the need for separate specialized equipment.
Solution Approach 2:
The patent introduces location information as an intermediary that mediates between the raw detection signal and the final hit determination. The location data acts as a filter or mediator that helps the system correctly interpret detection signals, distinguishing between valid hits and false positives without requiring complex signal processing.

Function Achieved in This Case
Enhances realism in military exercises by accurately distinguishing between indoor and outdoor shots, reducing false positives, and providing detailed hit assessments for improved training evaluation.
Implementation Method 1
A said transmitter used in a simulation system of this type is either simulating the firing of a shot synchronized with the firing of a blank by said firearm or without any such firing by carrying out a transmission of a signal simulating a projectile fired by the firearm. This transmitter normally emits laser pulse for such a simulation
Implementation Method 2
means to be arranged on the body of a said soldier for detecting a hit by a shot simulated by a said transmitter on a firearm of another soldier
Data Source
AI summary
A simulation system for use in military exercise of combat in an area having at least one building has a transmitter arranged on a firearm for simulating firing of a shot and a detector to be arranged on the body of a soldier. Sensors are adapted to sense whether the transmitter and the detector are located indoors or outdoors. The detector is designed to discriminate between normal power signals fired from outdoors and indoors, whereas the transmitters is adapted to emit signals of normal power when located outdoors and signal of normal power as well as a substantially lower power when located indoors.
