Solution Overview

Problem

Existing systems lack effective and timely detection of gunshots in physical spaces, which delays the response of law enforcement and administrative personnel, potentially leading to increased danger during active shooter situations.

Innovation Solution

A system comprising particulate sensors integrated with computers and wireless or wired communication devices that detect increases in air particulate matter, transmit information about gunshots to administrative personnel and first responders, and display the location on an interactive electronic map, allowing for quick identification and tracking of the shooter's movement.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Speed

If traditional detection methods are used, then system complexity is reduced, but detection speed and accuracy of gunshot events deteriorate

Engineering Contradiction:
Improvedetection speedVSAvoidsystem complexity
Core Design Contradiction:
SpeedVSDevice complexity

Solution Approach 1:

The system divides the physical space into multiple zones with distributed sensors, each independently detecting particulate matter. This segmentation enables parallel detection across the space, improving overall detection speed without requiring a single complex centralized system.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The particulate matter sensors serve multiple functions: detecting gunshot events, tracking shooter movement, and providing real-time location data. This multi-functionality improves detection capabilities without proportionally increasing system complexity.

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

2Loss of time

If real-time tracking is implemented, then response time is improved, but information processing requirements increase

Engineering Contradiction:
Improveresponse timeVSAvoidinformation processing load
Core Design Contradiction:
Loss of timeVSLoss of information

Solution Approach 1:

The system extracts only the critical information needed for rapid response - the location and movement of the shooter - from the overall sensor data stream. This extraction approach enables fast response times by focusing processing resources on essential tracking data rather than analyzing all sensor information.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The system creates simplified digital representations (copies) of the shooter's location and movement trajectory on electronic maps. These copied visual representations allow rapid situational awareness and decision-making without requiring complex real-time analysis of raw sensor data.

Inventive Principle:
Principle #26Copying

3Area of stationary object

If multiple sensors are deployed, then detection coverage is improved, but system cost and complexity increase

Engineering Contradiction:
Improvedetection coverageVSAvoidsystem complexity
Core Design Contradiction:
Area of stationary objectVSDevice complexity

Solution Approach 1:

Each sensor node operates autonomously, independently detecting and processing particulate matter data at its location. This self-service capability allows multiple sensors to be deployed for expanded coverage without proportionally increasing central system complexity, as each node handles its own data processing.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The system combines data from multiple independent sensor nodes into a unified tracking picture, merging individual detection capabilities into comprehensive spatial awareness. This merging approach improves overall detection coverage while managing system complexity through integrated data processing.

Inventive Principle:
Principle #5Merging (Combining)
