Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple different types of projectiles are loaded onto a mobile carrier, then the versatility of the weapon system is improved, but the aiming precision becomes inconsistent across different projectile types
Solution Approach 1:
The system performs preliminary simulation and evaluation of multiple projectiles before actual firing. The selection module predicts navigation precision for each projectile type under current environmental conditions (including jamming scenarios) and selects the optimal projectile in advance, ensuring consistent aiming precision while maintaining versatility.
Solution Approach 2:
The system uses feedback from simulated performance data and environmental condition sensing to dynamically evaluate and select the best projectile. The selection module continuously monitors conditions and uses this feedback to choose projectiles that will maintain precision despite variations in type and environment.
2Reliability
If environmental conditions such as jamming are present, then the reliability of navigation systems deteriorates, but the need for accurate target acquisition remains critical
Solution Approach 1:
The system applies preliminary anti-action by simulating jamming effects and evaluating how different projectiles would perform under such conditions before actual firing. The selection module chooses projectiles that have demonstrated resilience to jamming in simulations, thereby maintaining target acquisition accuracy despite navigation reliability deterioration caused by environmental interference.
3Measurement precision
If simulation and selection processing is performed for multiple projectiles, then the precision of projectile selection is improved, but the time required for decision-making increases
Solution Approach 1:
The system applies partial action by evaluating only the most critical performance parameters (navigation precision under expected conditions) rather than all possible parameters. The selection module focuses computation on the subset of projectiles and conditions most relevant to the current mission, reducing decision time while maintaining selection precision.
