Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Simulated firearm training systems lack a modular, self-contained laser projection system that can be removably disposed in a training firearm without physical or electrical connection, limiting the ability to accurately detect and record laser fire accuracy, especially in multi-user scenarios and posing safety risks during live fire training.
Innovation Solution
A multi-function, modular laser insert is designed for the chamber of a training firearm, featuring a laser module that emits visible or invisible light upon receiving an optical signal, with adjustable screws for maintaining beam accuracy and modular components for unique user identification patterns, allowing optical communication with the training firearm without wiring.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a laser projection system is integrated into a training firearm, then simulated fire training capability is improved, but device complexity increases
Solution Approach 1:
The laser projection system is divided into separate modular components including a laser module, power source, and control circuitry that can be independently installed and removed from the training firearm, reducing overall system complexity while maintaining full training functionality
Solution Approach 2:
The laser module is designed to work with multiple types of training firearms through a universal mounting interface, and can serve multiple training functions including accuracy training and safety instruction, thereby improving versatility without proportionally increasing complexity
2Object-affected harmful factors
If the laser insert is removably disposed without physical connections, then safety is improved, but reliability of optical signal transmission deteriorates
Solution Approach 1:
An optical coupling interface with precision alignment features acts as an intermediary between the removable laser insert and the firearm body, ensuring reliable optical signal transmission while maintaining the safety benefit of no electrical connections
Solution Approach 2:
The system replaces electrical connection mechanisms with optical signal transmission through aligned apertures and windows, eliminating the need for physical wiring while maintaining reliable communication between the laser module and target detection system
3Productivity
If multiple users train with the same target, then training efficiency is improved, but difficulty of detecting and measuring accuracy deteriorates
Solution Approach 1:
Each user's laser module is assigned a unique local identifier or code that modulates the optical signal, allowing the target system to distinguish and record shots from different users simultaneously, thereby maintaining training efficiency while enabling accurate measurement of individual performance
