Multi-Directional Fire Suppression System with Thermal Trigger
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fire suppression systems for appliances lack the capability to disperse fire retardant in multiple directions effectively and fail to automatically alert users of a fire, leading to potential uncontrolled fires and safety risks.
Innovation Solution
A fire suppression system with a multi-point fire retardant dispersion mechanism, comprising a retrofittable extinguisher assembly with orthogonal and angled nozzles for comprehensive fire extinguishment and a communication assembly for user alerting, utilizing temperature sensors and wireless communication to notify users of rising temperatures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a single-point fire retardant dispersion system is used, then the device complexity is reduced, but the fire extinguishment effectiveness is insufficient
Solution Approach 1:
The fire suppression system divides the single dispersion point into multiple nozzle outlets arranged in specific patterns (orthogonal, angled, radial configurations). Each nozzle acts as an independent segment that disperses fire retardant in a specific direction, collectively providing comprehensive coverage of the appliance interior space to effectively extinguish fires from multiple locations simultaneously.
Solution Approach 2:
The system transitions from single-point (zero-dimensional) to multi-point (distributed spatial arrangement) fire retardant dispersion. Nozzles are positioned at different locations and orientations within the appliance, creating a three-dimensional dispersion pattern that covers the entire appliance interior, thereby improving fire suppression effectiveness without excessive complexity.
2Reliability
If fire suppression system is designed as custom-built for each appliance, then the fire extinguishment effectiveness is optimized, but the ease of manufacture and installation is reduced
Solution Approach 1:
The fire suppression system is designed as a universal, retrofittable unit that can be installed in various appliance types (microwaves, ovens, refrigerators) without requiring custom design for each appliance. The standardized nozzle assembly with multiple outlets can be adapted to different appliance interiors, making the system easy to manufacture and install while maintaining effective fire suppression performance across different applications.
3Object-affected harmful factors
If no user alerting system is included, then the device complexity is reduced, but the user safety is compromised
Solution Approach 1:
The fire suppression system incorporates an alerting mechanism that provides feedback to users when a fire condition is detected or when the system has discharged. This feedback loop ensures user awareness of the fire hazard and system operation, enhancing safety without requiring complex control systems - typically using simple visual (LED indicators) or audible (buzzer) alert components integrated into the existing system architecture.

AI summary
A fire suppression system including an extinguisher assembly, a trigger assembly and a communication assembly is disclosed. The extinguisher assembly including a fire extinguisher having a fire retardant within. The fire extinguisher including a plurality of nozzles aimed in various direction for dispersing the fire retardant in multiple directions. The trigger assembly being atop of the fire extinguisher. A lever included within the trigger assembly to actuate the trigger when needed. The lever suspended above of the trigger by a melting pillar. The melting pillar melting when temperatures from a fire within the appliance reach a predetermined threshold to allow said lever to engage the trigger from above. Thereby causing the fire retardant to be dispersed in multiple directions by the plurality of nozzles to extinguish the fire. This helps to protect users from costly repairs and potentially dying within the fire.
