Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If prior art robotized fire-fighting units use basic coordinate calculation without feedback, then the device complexity is reduced, but the manufacturing precision of jet aiming is deteriorated
Solution Approach 1:
The patent implements a feedback mechanism where television cameras mounted on the fire-fighting unit capture images of the water jet trajectory. These images are processed to determine actual jet coordinates, which are then fed back to the control system to adjust aiming parameters in real-time, significantly improving jet aiming accuracy
Solution Approach 2:
The patent replaces traditional mechanical feedback mechanisms with a television-based optical measurement system. Instead of using complex mechanical sensors to track jet position, the system uses video imaging and digital image processing to detect jet coordinates, reducing mechanical complexity while improving measurement precision
2Device complexity
If prior art units lack feedback on real jet movement, then the device complexity is reduced, but the reliability of fire-fighting operations is deteriorated
Solution Approach 1:
The control system continuously receives feedback from television cameras about the actual water jet position and trajectory. This real-time information allows the system to compensate for deviations caused by wind, pressure variations, and nozzle wear, maintaining reliable fire-fighting performance under varying conditions
Solution Approach 2:
The system performs self-diagnosis and self-adjustment by automatically monitoring its own jet trajectory and correcting aiming errors without external intervention. The television system and control algorithm work together to enable the unit to self-regulate its fire-fighting effectiveness
3Ease of operation
If prior art units use only calculated ballistic parameters, then the ease of operation is improved, but the measurement precision of jet direction is deteriorated
Solution Approach 1:
The patent replaces manual aiming calculations with an automated television-based measurement system. The control system automatically processes video images to determine jet coordinates and adjusts aiming parameters without requiring manual calculation or complex operator intervention, maintaining ease of operation while achieving high measurement precision
Solution Approach 2:
The television camera system acts as an intermediary between the physical jet trajectory and the control system. It captures optical information about jet position and converts it into measurable data, serving as a bridge that enables precise non-contact measurement of jet direction
4Device complexity
If prior art units lack three-dimensional coordinate determination, then the device complexity is reduced, but the adaptability to different fire scenarios is deteriorated
Solution Approach 1:
The patent transitions from two-dimensional aiming to three-dimensional coordinate determination by incorporating vertical angle measurement capability. The television system captures spatial information in three dimensions, enabling the unit to accurately target fires at different elevations and distances, significantly expanding its application range to include indoor and outdoor scenarios
