Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If dedicated simulation missiles are developed to simulate specific targets, then the accuracy of thermal signature simulation is improved, but the time and resources required for development increase
Solution Approach 1:
The patent uses a simulation missile that copies only the essential aerodynamic properties and trajectory of the target missile, rather than creating a dedicated full-scale replica. This allows thermal signature simulation without developing a complete dedicated simulation missile for each target type.
Solution Approach 2:
The patent employs controllable heating elements that can dynamically adjust temperature parameters to match the thermal signature of different target missiles. By changing heating parameters rather than physical structure, the system can simulate various targets without redevelopment.
2Measurement precision
If dedicated simulation missiles are developed to simulate specific targets, then the accuracy of thermal signature simulation is improved, but the resource requirements increase
Solution Approach 1:
The simulation missile is designed with universal heating elements and control systems that can simulate multiple different target types. This multi-functional design eliminates the need for separate dedicated simulation missiles for each target, reducing overall resource requirements.
Solution Approach 2:
Instead of creating resource-intensive dedicated replicas, the system copies only the essential thermal signature characteristics using minimal heating elements, achieving simulation accuracy with reduced material and resource investment.
3Duration of action of moving object
If a platform survives the initiation of the heat source, then the simulation time window is extended, but the thermal and structural separation from subsystems is required
Solution Approach 1:
The patent divides the simulation missile into thermally separated zones: the heat source compartment is isolated from the main platform structure through thermal barriers. This segmentation allows the heat source to operate independently without compromising the platform's structural integrity, extending the simulation time window.
Solution Approach 2:
Thermal barrier materials act as intermediary layers between the heat source and the platform structure. These intermediaries protect the platform from excessive heat while allowing the heat source to function, thereby extending operational duration without requiring complete thermal isolation.
