Friendly Fire Prevention via Mesh Network Transponders
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Friendly fire incidents continue to occur due to poor visibility and lack of effective systems to identify and prevent unintentional cross-fire between friendly forces and assets in military and civilian environments, resulting in casualties and asset losses.
Innovation Solution
A system utilizing a network of navigation and communication devices (NCDs) with sensors and communication modules, forming a self-organized MESH network to identify and prevent friendly fire by sharing location, direction, and aim data among friendly assets, with remote administration and encryption for secure communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional weapons systems are used without advanced identification systems, then device complexity is low, but friendly fire incidents occur due to inability to identify friendly forces
Solution Approach 1:
The patent implements a universal identification system where all friendly forces (ground troops, aircraft, naval vessels, tanks) are equipped with transponders that can be identified by various sensor types (electro-optical, infrared, radar). This multi-functional approach allows a single identification infrastructure to protect across all military domains, resolving the contradiction by providing comprehensive friendly fire prevention through a standardized system that works universally across different weapon platforms and enemy detection methods.
Solution Approach 2:
The patent introduces transponders as intermediary devices that are attached to or integrated with friendly forces' equipment. These transponders act as mediators between the weapon system's sensors and the identification requirement, allowing the weapon system to reliably distinguish friendly from enemy forces without requiring complex sensor systems on every platform. The transponder intermediary resolves the contradiction by providing a simple, reliable identification mechanism that reduces friendly fire risk while adding minimal complexity.
2Reliability
If no identification system is implemented, then ease of operation is high, but casualties and asset losses occur due to unintentional cross-fire
Solution Approach 1:
The patent implements a self-service identification system where friendly forces carry their own transponders that automatically transmit identification signals. The weapon system's sensors automatically detect these signals and provide identification data to the fire control system. This self-service approach resolves the contradiction by enabling reliable casualty prevention through automatic identification without requiring complex manual procedures or intensive operator training, as the system operates autonomously once the transponders are attached.
3Measurement precision
If comprehensive sensor coverage is implemented to detect all friendly forces, then measurement precision of friendly force location is high, but device complexity increases due to multiple sensor types
Solution Approach 1:
The patent inverts the traditional approach by instead of equipping weapon systems with complex sensors to detect friendly forces, it equips the friendly forces themselves with active transponders that emit identification signals. This inversion resolves the contradiction by achieving high measurement precision of friendly force location through the transponders' known positions and signal characteristics, while reducing device complexity at the weapon system level since the identification function is shifted to the transponder-carrying friendly forces.
