Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for determining the deviation between the actual direction and desired direction of a launched projectile are inefficient, often requiring mechanical adjustments and limited in flexibility when targeting unknown positions.
Innovation Solution
A method and apparatus that utilize an image of a target area to indicate a position, determine the actual direction of a projectile, and calculate the deviation from the launch position to the desired direction, using a combination of camera and radar systems to provide real-time data and eliminate the need for mechanical adjustments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If mechanical adjustments are used to determine projectile deviation, then the system can provide directional guidance, but the device complexity increases and flexibility is limited
Solution Approach 1:
The patent replaces mechanical adjustment systems with an optical detection system comprising a camera and radar. The camera captures images of the target area and projectile position, while the radar tracks the projectile's actual direction. A processing unit calculates the deviation between actual and desired directions based on image data, eliminating the need for mechanical adjustments while maintaining directional guidance capability.
2Ease of operation
If mechanical adjustment systems are implemented, then directional control is achieved, but the adaptability for multiple targets and launches is reduced
Solution Approach 1:
The patent implements a universal system that can handle multiple targets and launches. The camera captures the entire target area, allowing selection of any position within the field of view. The radar can track multiple projectiles, and the processing unit calculates deviations for any selected target-position combination. This enables flexible adaptation to different targets and launch scenarios without requiring mechanical reconfiguration.
3Measurement precision
If real-time deviation determination is implemented using image processing, then flexibility and accuracy are improved, but the device complexity increases
Solution Approach 1:
The patent merges the camera and radar into an integrated system where both components work together to determine projectile deviation. The camera provides visual positioning information of the target area and projectile, while the radar provides precise motion tracking data. The processing unit combines these data streams to calculate the deviation between actual and desired directions, achieving high measurement precision through data fusion rather than requiring overly complex individual components.

AI summary
In a method of determining a deviation of a path of a projectile from a predetermined path, the method uses an image of a target area in which the desired path or direction is pointed out. Subsequently, the real direction or real path is determined and the deviation is determined.
