Solution Overview

Problem

Existing extended reality training systems for security personnel are limited in realism, particularly in simulating the use of multiple security tools and decision-making processes, and often use replicas that differ from real tools, affecting training effectiveness.

Innovation Solution

A trigger detection device for weapons that includes a housing, a trigger sensor, and a communication interface to transmit actuation data to an extended reality system, allowing realistic simulations of trigger movements, and a belt system with sensors and communication interfaces to track and simulate the use of multiple security tools.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If replicas of specific weapons are used in extended reality training programs, then handling training for that specific weapon is improved, but realism and applicability to real security situations deteriorates

Engineering Contradiction:
Improvetraining program setupVSAvoidtraining realism
Core Design Contradiction:
Ease of manufactureVSReliability

Solution Approach 1:

The system enables a single extended reality training platform to support multiple weapon types and security tools through configurable software modules and interchangeable tracking devices, allowing one system to serve multiple training purposes without requiring separate replica setups for each weapon type

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The system changes the parameter of weapon representation from fixed physical replicas to programmable virtual representations that can be configured to match various real weapon characteristics, enabling realistic simulation without physical replicas

Inventive Principle:
Principle #35Parameter changes

2Adaptability or versatility

If multiple different security tools are used in training, then decision-making process training is improved, but device complexity increases

Engineering Contradiction:

Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The extended reality system is designed as a universal platform that can track and simulate multiple different security tools including weapons, batons, and other equipment through a single integrated system, managing complexity through software configuration rather than separate physical systems for each tool

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The system introduces tracking devices and sensors as intermediaries between the security personnel and the extended reality system, enabling versatile tracking of multiple tool types through standardized interfaces that simplify system integration

Inventive Principle:
Principle #24Intermediary (Mediator)
