Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fire-extinguishing systems face challenges in rapidly and accurately identifying the fire's point of origin due to the time required for infrared ray detection, which can lead to incorrect identification and delayed firefighting operations.
Innovation Solution
A fire-extinguishing equipment that transmits electromagnetic waves in a predetermined direction and includes an electromagnetic wave-receiver to control the discharge of an extinguishing agent, ensuring accurate and rapid targeting of the fire.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If an infrared camera is used to detect infrared rays from flames to specify the fire's point of origin, then the fire-fighting operation can be performed, but time is needed for specifying the fire's point of origin and the operation may not be rapidly started
Solution Approach 1:
The patent applies preliminary action by pre-positioning electromagnetic wave transmitters at multiple locations before a fire occurs. When a fire is detected, the system immediately transmits electromagnetic waves toward potential fire origins without needing to first identify the exact location through infrared detection. This preliminary setup enables rapid response while maintaining accuracy through coordinated transmission and reception.
2Reliability
If an infrared camera is used to detect infrared rays, then fire detection is possible, but a point that is not the fire's point of origin may be mistaken for the fire's point of origin
Solution Approach 1:
The patent implements feedback by using electromagnetic wave receivers positioned at multiple locations to detect transmitted waves and determine the fire's location based on which receiver detects the waves first or with highest intensity. This feedback mechanism continuously monitors electromagnetic wave reception patterns to accurately identify the fire's point of origin, preventing mistaken identification by cross-validating signals from multiple receivers.
Solution Approach 2:
The patent applies segmentation by dividing the detection system into multiple independent electromagnetic wave transmitters and receivers positioned at different locations. Instead of relying on a single infrared camera, the system segments the detection function across multiple points, allowing each component to transmit or receive signals independently. This segmentation enables more precise location determination through signal analysis from multiple distributed points.

Function Achieved in This Case
Enables more accurate and rapid firefighting operations by ensuring the extinguishing agent is discharged only when the electromagnetic waves are received by the receiver at the fire's location, improving precision and speed compared to systems relying on infrared cameras.

AI summary
A fire-extinguishing equipment includes: a fire-extinguishing apparatus which transmits electromagnetic waves in a predetermined output direction and discharges an extinguishing agent; an electromagnetic wave-receiver which is provided in an fire extinguishing object and receives the electromagnetic waves; and a controller which controls the fire-extinguishing apparatus to start to discharge the extinguishing agent when the output direction is set to a direction of the fire extinguishing object and the electromagnetic wave-receiver receives the electromagnetic waves.
