Dynamic Sight for Moving Target Lead Calculation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Shooting sports involving moving targets face challenges in accurately determining target lead, as existing training aids provide ambiguous feedback and require trial-and-error learning, leading to frustration for beginners and limited improvement for advanced shooters.
Innovation Solution
A dynamic sight system mounted on a gun that calculates and displays the correct target lead by determining the initial velocity of a projectile, barrel rotation rate, and range, presenting lead angles to the user through a computing device and display, allowing for precise adjustments based on angular rotation and ballistics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If fixed lead estimate aids are used, then shooters receive lead guidance, but the estimate is only valid under specific conditions and does not adapt to variations
Solution Approach 1:
The sight system dynamically adjusts the lead estimate based on real-time detection of target range, target velocity, and shot velocity, transforming a static fixed lead estimate into a dynamic adaptive system that responds to changing shooting conditions
Solution Approach 2:
The system incorporates feedback from range detection, velocity measurement, and shot outcome analysis to continuously refine and adjust the lead estimate, ensuring accuracy across varying conditions rather than relying on predetermined fixed values
2Loss of information
If tracer ammunition is used, then shooters receive visual feedback on shot direction, but the feedback is ambiguous and does not clearly indicate lead accuracy
Solution Approach 1:
The system provides structured feedback by detecting target position relative to the shot pattern and communicating clear lead accuracy information through the sight interface, eliminating the ambiguity inherent in tracer ammunition interpretation
Solution Approach 2:
The sight system acts as an intermediary between the shot and the shooter, translating raw shot data and target position into clear, actionable lead accuracy information, removing the need for the shooter to directly interpret ambiguous tracer patterns
3Loss of information
If video analysis is used, then shooters receive post-shot feedback, but the feedback requires trial and error and suffers from the same ambiguity as tracer ammunition
Solution Approach 1:
The system performs preliminary calculation of the correct lead angle based on detected target and shot parameters before the shot is fired, presenting the lead angle to the shooter in advance rather than requiring post-shot analysis and trial-and-error learning
Solution Approach 2:
The system provides immediate feedback on lead accuracy through target position detection relative to the shot pattern, eliminating the delayed and ambiguous feedback from video analysis and enabling faster learning without trial and error
4Reliability
If advanced shooters use existing aids, then they maintain hit results, but they cannot differentiate between center hits and off-center hits for further improvement
Solution Approach 1:
The system provides differentiated feedback by detecting and communicating the specific location of hits relative to the target center, enabling advanced shooters to distinguish between center and off-center hits for continued improvement while maintaining hit consistency
