Innovation Solution
A fire alarming and suppression system with a vertically arranged supporting assembly, image information acquisition unit, local controller, and one-button alarm device, including thermal and color cameras for accurate fire detection, and a fire blanket storage box for immediate response.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional fire alarming systems are installed in large outdoor charging station spaces, then fire detection coverage is improved, but installation complexity and system integration difficulty increase
Solution Approach 1:
The patent combines multiple fire detection functions (image acquisition, thermal analysis, color analysis) into a single integrated fire alarming system deployed at charging piles, eliminating the need for complex distributed sensor networks across large outdoor spaces while maintaining comprehensive fire detection coverage
Solution Approach 2:
The fire alarming system at each charging pile serves multiple functions: it monitors the charging vehicle, analyzes thermal images for temperature anomalies, processes color images for flame detection, and provides local alarm signals, thereby achieving comprehensive fire detection coverage through a multi-functional unified device rather than multiple specialized components
2Reliability
If fire alarming systems are deployed to monitor all charging vehicles, then fire detection capability is improved, but maintenance and service accessibility deteriorate
Solution Approach 1:
The patent divides the fire alarming system into independent modular units deployed at each charging pile, where each unit contains complete fire detection and alarm functionality. This segmentation allows maintenance personnel to access and service individual modules independently without disrupting the entire system, improving maintenance accessibility while maintaining comprehensive fire detection capability across all charging vehicles
3Loss of time
If rapid fire detection is implemented to prevent chained burning, then response time is improved, but system complexity increases
Solution Approach 1:
The system performs preliminary analysis by continuously monitoring thermal images for temperature elevation trends and color images for early flame signs before actual fire outbreaks. This preliminary detection capability enables rapid response to potential fire hazards at charging vehicles, preventing chained burning incidents while maintaining relatively simple system architecture through proactive rather than reactive monitoring
