Solution Overview

Problem

Manual testing of event devices in large facilities is prone to errors due to the need for continuous communication between technicians and control panels, especially when multiple devices are closely located or network connectivity is unavailable, leading to potential misidentification of devices during maintenance and inspection.

Innovation Solution

A mobile device system that uses beacons and indicators to differentiate between event devices, allowing users to determine signal strength and interact with the correct device even without network connectivity, through a device identification analysis and audit actions, ensuring accurate testing and maintenance.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If manual testing of event devices is performed with continuous communication between technician and control panel, then device identification accuracy may be maintained, but testing efficiency and reliability deteriorate when network connectivity is unavailable or multiple devices are closely located

Engineering Contradiction:
Improvedevice identification accuracyVSAvoidtesting operation difficulty
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The patent introduces beacons as intermediary devices that emit signals to enable direct communication between the mobile device and event devices. This intermediary system allows the mobile device to receive unique identifiers and signal strength information from beacons, eliminating the need for continuous technician-control panel communication while maintaining accurate device identification even when multiple devices are closely located or network connectivity is unavailable.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Productivity

If technicians visually inspect and functionally test event devices simultaneously, then maintenance completeness is improved, but error rate increases due to misidentification of devices

Engineering Contradiction:
Improvemaintenance completion efficiencyVSAvoidtesting accuracy
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The patent implements a feedback mechanism where the mobile device continuously receives signal strength information from beacons associated with event devices. As the technician moves through the facility, the system provides real-time feedback about which event device is currently closest (based on strongest signal), allowing the technician to confirm device identity before and during testing. This feedback loop prevents misidentification errors while maintaining efficient simultaneous visual inspection and functional testing.
