Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional alarm systems are used without advanced analysis, then the system is simple and easy to operate, but false alarms occur frequently causing financial burden and resource waste
Solution Approach 1:
The system performs preliminary analysis of event sequences and patterns before false alarms occur. By analyzing historical event data and identifying precursors to false alarms, the system proactively generates recommendations to prevent false alarms before they happen, rather than simply reacting to them after occurrence.
Solution Approach 2:
The patent introduces an intermediary analysis layer between the alarm events and the response actions. This intermediary system analyzes event sequences, identifies patterns indicative of false alarms, and generates recommendations, thereby mediating between the raw alarm signals and the final response decisions to reduce false alarm impacts.
2Reliability
If comprehensive event analysis is performed to identify false alarm patterns, then false alarm reduction effectiveness improves, but processing time and computational resources increase
Solution Approach 1:
The system performs preliminary analysis of event sequences and patterns before false alarms occur. By analyzing historical event data and identifying precursors to false alarms, the system proactively generates recommendations to prevent false alarms before they happen, rather than simply reacting to them after occurrence.
Solution Approach 2:
The patent replaces manual analysis of alarm events with automated computational analysis using processors and algorithms. This substitution enables comprehensive analysis of event sequences and patterns without the time constraints of manual review, allowing the system to process large volumes of data efficiently and generate recommendations automatically.
3Productivity
If automated parameter updates are implemented for self-healing, then system maintenance efficiency improves, but risk of incorrect automatic changes increases
Solution Approach 1:
The system implements self-service capabilities by automatically generating and implementing parameter updates based on analyzed event patterns. The system can autonomously identify issues, generate corrective recommendations, and apply fixes without requiring constant human intervention, thereby improving maintenance efficiency and enabling the system to heal itself from false alarm conditions.
Solution Approach 2:
The patent incorporates feedback mechanisms where the system monitors the effects of implemented parameter updates and uses this information to refine future recommendations. By continuously analyzing the outcomes of automated changes and adjusting its analysis algorithms accordingly, the system learns from past performance and improves the accuracy of its self-healing capabilities over time.

AI summary
A system for preventing a false alarm that occurs at a building, the system includes a processing circuit configured to receive, via a communications interface, building data including events for the building devices. The processing circuit is configured to determine, based on the events, whether a false alarm rule has triggered, where the false alarm rule indicates relationships between one or more of the events that is indicative of a situation at the building site that causes the false alarm, generate a parameter update for at least one of the plurality of building devices in response to determining that the false alarm rule has triggered, and implement the parameter update by providing, via the communications interface, the parameter update to the at least one of the building devices.
