Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of stationary object
If elevating fire truck or aerial ladder fire truck is adopted, then fire extinguishing height is improved, but vehicle width, length, ride height and gross mass increase making it difficult to deploy in narrow streets
Solution Approach 1:
The system divides the fire extinguishing function into two independent parts: (1) a compact launcher that can be deployed in narrow streets with normal vehicle dimensions, and (2) high-altitude fire extinguishing bombs that provide the required extinguishing height. This segmentation allows the launch vehicle to be small while the bombs deliver water to high altitudes.
Solution Approach 2:
The fire extinguishing bomb acts as an intermediary carrier that transfers water from the ground-based launcher to the high-altitude fire source. The bomb is propelled to high altitude and then releases water at the target location, enabling indirect fire extinguishing that bypasses the vehicle size limitation.
2Reliability
If Bronto fighting truck is used, then fire fighting capability is improved, but import price up to 22 million yuan makes it unaffordable for most domestic cities
Solution Approach 1:
The system uses disposable fire extinguishing bombs instead of expensive reusable elevating platforms. Each bomb is a low-cost, single-use device that is launched to deliver water and then discarded, eliminating the need for costly 60-ton vehicles while maintaining fire extinguishing effectiveness.
Solution Approach 2:
The patent replaces the complex mechanical elevating system with a simpler pneumatic or electromagnetic launch system. Instead of mechanically lifting a 60-ton vehicle with expensive components, the system uses high-speed launch technology to propel lightweight bombs to high altitude, significantly reducing equipment cost.
3Force
If fire extinguishing bomb with center booster is used, then propulsion force is improved, but large amount of high-explosive fragments are produced making it unsuitable for urban environments
Solution Approach 1:
The patent extracts and removes the high-explosive booster component from the fire extinguishing bomb, retaining only the pneumatic or electromagnetic propulsion mechanism. This extraction eliminates the harmful high-explosive fragments while preserving the ability to propel the bomb to high altitude for fire extinguishing.
4Ease of operation
If blind launching method is used, then operation simplicity is improved, but hitting accuracy is not high
Solution Approach 1:
The system incorporates feedback mechanisms including wind speed and direction sensors, temperature sensors, and humidity sensors that provide real-time environmental data to the trajectory calculation module. This feedback allows the system to adjust launch parameters dynamically, maintaining high accuracy while keeping the operation process automated and simple.
Solution Approach 2:
The system performs preliminary trajectory calculation and environmental sensing before launch. The control system pre-computes the optimal launch angle and velocity based on predicted wind conditions and target location, allowing operators to simply execute the pre-planned launch without complex real-time adjustments.
