Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current fire detection systems, particularly in unpopulated areas, are costly and inefficient due to reliance on tower-mounted cameras and infrared sensors, which require constant power and maintenance, and existing smoke detector networks are also expensive and resource-intensive.
Innovation Solution
Radio-based heat detection pellets with thermal switches and transmitter circuits that send alarm signals to remote locations when exposed to high temperatures, allowing for triangulation of fire location and direction without continuous power consumption, enabling cost-effective and efficient detection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If tower-mounted cameras and infrared sensors are used for fire detection, then detection capability is improved, but cost and device complexity increase significantly
Solution Approach 1:
The patent employs disposable heat-detecting pellets that are inexpensive and single-use. Each pellet contains a thermal switch and radio transmitter that activate temporarily when exposed to fire heat, sending location data before being consumed. This replaces expensive, complex permanent infrastructure with cheap, simple disposable units.
Solution Approach 2:
The patent replaces mechanical/optical detection systems (cameras, infrared sensors requiring line-of-sight) with thermal-based detection using heat-sensitive chemical or electronic switches. This substitution eliminates the need for complex optical paths, power supplies, and continuous operation systems.
2Measurement precision
If tower-mounted cameras and infrared sensors are deployed, then fire detection accuracy is improved, but cost increases
Solution Approach 1:
The patent uses inexpensive disposable pellets containing simple thermal switches and radio transmitters. These pellets cost fractions of camera systems while providing sufficient detection accuracy through heat threshold triggering, dramatically reducing deployment costs.
Solution Approach 2:
Instead of using expensive original detection equipment, the patent employs numerous simple copies (pellets) that replicate the essential detection function. Each pellet is a simplified copy that detects heat and transmits location, collectively providing comprehensive coverage at low cost.
3Area of stationary object
If a network of smoke detectors is implemented, then fire detection coverage is improved, but maintenance requirements and cost increase
Solution Approach 1:
The patent uses disposable pellets that require no maintenance. Each pellet is designed for single use - once it detects fire and transmits its location, it is consumed. This eliminates the maintenance burden entirely, replacing the need to service permanent detector networks.
Solution Approach 2:
The pellets are self-activating and self-transmitting. When exposed to fire heat, the thermal switch automatically triggers the radio transmitter to send its location data. The system requires no external power, control, or maintenance - it serves itself completely autonomously.
4Measurement precision
If optical sensors with line of sight are used, then detection precision is improved, but power consumption and system complexity increase
Solution Approach 1:
The patent replaces optical detection requiring line-of-sight and continuous power with thermal detection using heat-sensitive switches. The thermal switches are passive - they respond to heat without requiring power until triggered, eliminating continuous power consumption while maintaining detection precision through heat threshold sensing.
Solution Approach 2:
Instead of continuous operation, the system uses event-triggered periodic action. The pellets remain dormant until fire heat activates their thermal switches, which then trigger a brief radio transmission. This periodic, event-driven operation eliminates continuous power consumption while maintaining detection capability.
