Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If radar sensor units are integrated into the missile body, then target detection accuracy is improved, but aerodynamic performance deteriorates
Solution Approach 1:
The radar antennas are integrated into recesses formed in the missile body, allowing the radar sensor units to be nested within the aerodynamic shell. This nesting approach enables radar functionality while maintaining the streamlined outer surface required for aerodynamic efficiency.
Solution Approach 2:
The missile body is designed with localized recesses at specific positions where radar antennas need to be mounted. This local modification approach allows radar integration only where necessary, preserving the aerodynamic quality of the overall missile body while providing functional openings for radar operation.
2Measurement precision
If multiple radar antennas are mounted on the missile body, then target detection capability is improved, but device complexity increases
Solution Approach 1:
Multiple radar antennas are combined and mounted in an array configuration on the missile body. This merging approach consolidates multiple detection elements into a unified radar sensor unit, improving target detection capability through array processing while managing complexity through integrated mounting structures.
3Ease of manufacture
If radar antennas are integrated into the missile body, then ease of manufacture is improved, but aerodynamic performance deteriorates
Solution Approach 1:
The radar antennas are integrated into recesses formed in the missile body, allowing the radar sensor units to be nested within the aerodynamic shell. This nesting approach enables radar functionality while maintaining the streamlined outer surface required for aerodynamic efficiency.
Solution Approach 2:
The radar antennas are designed to be flush with the outer surface of the missile body, creating a smooth transition that maintains aerodynamic properties. This flush mounting approach allows the shell to remain continuous and streamlined, reducing aerodynamic disruption while facilitating antenna integration.
