Solution Overview

Problem

Commercially available intrusion detection systems often generate false alarms when authorized operators access protected premises without first disarming the system, leading to unnecessary alerts and operational inefficiencies.

Innovation Solution

A system that automatically disarms the intrusion detection system by establishing a Bluetooth Low Energy connection with registered mobile communicators in the vicinity, communicating the system's armed state, and receiving instructions to disarm using a powerG protocol, thereby preventing false alarms.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If manual disarming by authorized operator is used, then system security is maintained, but false alarms occur when operator accesses premises without disarming

Engineering Contradiction:

Improvealarm accuracyVSAvoidoperator convenience

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The system performs preliminary detection of the operator's presence via mobile device proximity detection before an intrusion alarm can be generated. When the mobile device is detected in the premises vicinity, the system proactively disarms itself in advance, preventing the false alarm condition from occurring.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system continuously monitors the proximity of registered mobile devices and uses this feedback to automatically adjust its armed state. The feedback loop detects mobile device presence and triggers automatic disarming, eliminating the need for manual operator action while maintaining security.

Inventive Principle:

Principle #23Feedback

2Reliability

If automatic disarming via mobile device detection is implemented, then false alarms are reduced, but system complexity increases

Engineering Contradiction:

Improvealarm accuracyVSAvoidsystem architecture

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

A mobile device serves as an intermediary between the authorized operator and the intrusion detection system. The mobile device communicates presence information to the system via proximity detection, enabling automatic disarming without requiring complex direct integration between the operator and system.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The intrusion detection system performs self-service by automatically detecting mobile device presence and disarming itself without requiring external manual intervention. This self-service capability reduces false alarms while keeping the system architecture relatively simple by using existing mobile device detection technologies.

Inventive Principle:

Principle #25Self-service

3Measurement precision

If continuous monitoring of mobile devices is performed, then automatic disarming accuracy is improved, but energy consumption increases

Engineering Contradiction:

Improveproximity detection accuracyVSAvoidpower consumption

Core Design Contradiction:

Measurement precisionVSUse of energy by moving object

Solution Approach 1:

Instead of continuous monitoring, the system performs periodic proximity checks for mobile devices. The monitoring occurs at intervals or triggered by specific events (such as when the system transitions to armed state), maintaining detection accuracy while significantly reducing power consumption compared to continuous monitoring.

Inventive Principle:

Principle #19Periodic action
