Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for a system that automatically detects and responds to fires in battery systems within data centers to prevent irreversible damage, as existing methods may not effectively address the hazards posed by fires in such facilities.
Innovation Solution
A fire response system that monitors battery cell sets using multiple sensors, detects fire hazards, and executes a controlled sequence of operations including power cut-off, oxygen cut-off, and cooling operations, which may involve activating a fire extinguishing patch or spraying a fire extinguishing agent, based on triggering conditions such as temperature and smoke levels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If automatic fire detection and response systems are implemented in battery systems, then fire response speed and effectiveness are improved, but system complexity and cost increase
Solution Approach 1:
The battery system is divided into multiple battery cell sets with individual fire response capabilities for each set. Each battery cell set includes its own fire hazard detection sensors, fire extinguishing patches, and cooling operations, allowing localized response without requiring complex centralized control for the entire battery system.
Solution Approach 2:
Fire extinguishing patches are pre-installed on each battery cell set and fire hazard detection sensors are pre-positioned to detect early signs of fire. The system is prepared in advance with fire response sequences predefined, enabling immediate automatic response when hazards are detected without requiring complex real-time decision-making.
2Reliability
If multiple fire response operations (power cut-off, oxygen cut-off, cooling) are executed in sequence, then fire suppression effectiveness is improved, but response time and system complexity increase
Solution Approach 1:
The fire response system executes operations in a predefined periodic sequence: power cut-off operation first, followed by oxygen cut-off operation, and then cooling operation. This structured periodic approach ensures all necessary operations are performed systematically while maintaining predictable response timing.
Solution Approach 2:
The fire response sequence is predetermined with all operations planned in advance. When fire hazards are detected, the system automatically executes the pre-planned sequence of power cut-off, oxygen cut-off, and cooling operations without requiring real-time complex decision-making, reducing response time while maintaining effectiveness.
3Speed
If fire response operations are automated based on sensor detection, then response speed is improved, but false activation risk and system complexity increase
Solution Approach 1:
Fire hazard detection sensors are positioned at specific locations on each battery cell set to detect local fire hazards. The fire response system activates based on local sensor readings at the specific battery cell set level, allowing targeted response only where hazards are detected rather than blanket activation across the entire battery system.
Solution Approach 2:
The fire hazard detection sensors continuously monitor battery cell sets and provide feedback to the fire response system. When sensor readings indicate fire hazards meeting predefined thresholds, the system activates the fire response sequence. This feedback mechanism enables automatic response while using objective sensor data to reduce false activations.
