Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If traditional sprinklers are installed on the indoor ceiling, then fire suppression is provided, but the abnormal high temperature is not transferred to the sprinkler at the beginning of fire occurrence, resulting in delayed fire extinction
Solution Approach 1:
The patent replaces traditional mechanical sprinkler systems with an automated fire suppression system that uses optical detection (ultraviolet and infrared sensors) and thermal imaging to detect fires. The system uses a controller to coordinate detection and suppression actions, eliminating the reliance on thermal transfer to mechanical sprinkler heads and enabling immediate response at the ignition point.
Solution Approach 2:
The fire suppression system automatically detects fires using ultraviolet and infrared sensors, calculates ignition point coordinates, tracks the ignition point, and suppresses the fire without human intervention. The system serves itself by integrating detection, calculation, tracking, and suppression functions into an autonomous system that responds immediately to fire occurrence.
2Measurement precision
If fire detection units simply detect fire occurrence and control water spraying to the fire area, then fire suppression is achieved, but the system cannot accurately identify real fire events or track ignition points for precise targeting
Solution Approach 1:
The patent combines multiple detection functions (ultraviolet sensing, infrared sensing, thermal imaging) and calculation functions (ignition point coordinate calculation) into an integrated automatic ignition point tracking detection module. This merging of functions enables precise ignition point identification while managing system complexity through integration rather than separate components.
Solution Approach 2:
The automatic ignition point tracking detection module performs multiple functions: detecting fire occurrence, calculating ignition point coordinates, tracking the ignition point, and providing information to the controller for precise targeting. This multi-functional module achieves accurate ignition point identification without requiring entirely separate systems for each function.
3Reliability
If the ejection nozzle is fixed in position, then the structure is simple, but the system cannot track and target moving ignition points for effective fire suppression
Solution Approach 1:
The patent makes the casing rotatable in the horizontal direction and the ejection nozzle pivotable in the vertical direction, transforming the fixed structure into a dynamic system. This allows the nozzle to track and target moving ignition points effectively, ensuring reliable fire suppression while managing complexity through coordinated rotational and pivotal movements.

AI summary
A fire suppression system for automatically tracking an ignition point comprises a fire extinguishing agent spraying module comprising: a casing installed to be rotatable in a horizontal direction in a monitoring target area; and an ejection nozzle installed on the casing to be pivotable in a vertical direction and configured to eject a fire extinguishing agent to a fire occurrence point in the monitoring target area; an automatic ignition point tracking detection module disposed close to the ejection nozzle and configured to detect whether a fire has occurred in the monitoring target area and to calculate coordinates of an ignition point; and a controller configured to rotate the casing and pivot the ejection nozzle based on the coordinates of the ignition point calculated by the automatic ignition point tracking detection module, and ejects the fire extinguishing agent to the ignition point.
