Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If real-time calculation and display of shooting area and hit probability indicator are implemented, then the operator's ability to accurately launch guided missiles is enhanced, but the device complexity increases
Solution Approach 1:
The display system is segmented into distinct functional components: a shooting area display unit that visualizes the effective engagement zone, and a hit probability indicator unit that separately displays whether the target is within range. This segmentation allows each component to perform its specific function independently, reducing overall system complexity while maintaining high measurement precision for hit probability determination.
Solution Approach 2:
The patent introduces an intermediary processing system that receives raw data from multiple sensors (radar, GPS, inertial measurement units), calculates the shooting area and hit probability, and translates this information into visual displays. This intermediary layer simplifies the interface between complex sensor systems and the operator, reducing perceived device complexity while enabling precise real-time measurements of hit probability.
2Loss of information
If real-time display of shooting area and indicator position is implemented, then the information availability to operator is improved, but the calculation complexity increases
Solution Approach 1:
The system performs preliminary calculations of the shooting area boundaries and indicator position based on pre-stored missile performance parameters and current aircraft state. By pre-calculating and storing these relationships, the system reduces real-time computational complexity while ensuring complete information availability for hit probability assessment.
Solution Approach 2:
The patent creates a simplified graphical copy or representation of the three-dimensional shooting volume on a two-dimensional display. This graphical copy includes the shooting area boundary and indicator position, providing complete information about hit probability in an easily interpretable visual format without requiring complex real-time 3D rendering calculations.
3Measurement precision
If the indicator position is calculated based on yaw angle and horizontal distance, then the spatial accuracy of display is improved, but the computational load increases
Solution Approach 1:
The indicator position calculation system dynamically adjusts its computational approach based on aircraft motion state. During steady flight, simpler calculation methods are used, while during maneuvering, the system activates more precise yaw angle and horizontal distance calculations. This dynamic adaptation maintains high spatial accuracy for indicator position while reducing average energy consumption of the processor.

AI summary
An apparatus for displaying a shooting area of a guided missile is proposed. The apparatus may include a display, a memory, and a processor. The processor may display the shooting area of the guided missile and an indicator indicating whether the guided missile can hit a target on the display based on a size of the shooting area. The processor may display the indicator having an X-axis position calculated based on a yaw angle between a longitudinal axis line and the target and a horizontal distance from the center of the display to the shooting area, and a Y-axis position calculated based on a pitch direction angle between the longitudinal axis line and the target and a vertical distance from the center of the display to the shooting area. The indicator may indicate that the guided missile can hit the target when the indicator is displayed within the shooting area.
