Event Input Self-Testing With Continuous Hazard Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Manual testing of event input devices in large facilities is prone to errors, time-consuming, and disruptive, often leading to missed hazard events due to the need for multiple users and difficult access to devices.
Innovation Solution
An automated system where event input devices can perform self-testing while remaining in an active mode for hazard detection, using a controller to manage test sequences and alert users of any detected hazards through a mobile interface.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual testing of event input devices is performed, then testing can be conducted, but it is time-consuming and prone to errors leading to missed hazard events
Solution Approach 1:
The event input device performs automated self-testing by generating test signals internally and detecting its own responses, eliminating the need for manual intervention. The device tests its hazard detection capabilities autonomously while remaining in active monitoring mode, resolving the contradiction between reliable testing and time consumption.
Solution Approach 2:
The device maintains continuous hazard detection capability throughout the testing process by remaining in active mode. The self-test is integrated into the ongoing monitoring operation, allowing the device to perform both testing and hazard detection simultaneously without interruption or time loss.
2Ease of operation
If manual testing requires multiple users and visual inspection, then testing can be performed, but it is disruptive to facility occupants and difficult to access devices
Solution Approach 1:
The event input device autonomously performs testing without requiring physical access by technicians or visual inspection by multiple users. The device initiates and completes self-tests independently, eliminating disruptions to facility occupants and removing accessibility barriers for hard-to-reach devices.
3Reliability
If event input devices are placed in test mode for manual testing, then testing can be conducted, but hazard detection capability is lost during testing
Solution Approach 1:
The event input device performs multiple functions simultaneously: it conducts automated self-testing while maintaining its hazard detection capability. The device integrates testing operations into its active monitoring mode, allowing it to serve both testing and hazard detection purposes without switching modes or compromising either function.
Solution Approach 2:
The hazard detection function continues uninterrupted during automated testing. The device maintains active monitoring status throughout the self-test process, ensuring continuous hazard detection capability while performing automated testing, thus eliminating the need to switch to a separate test mode.
