Archery Sight Tape Selection via Ballistic Calculation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for selecting archery sight tapes require multiple shots at long distances, making them time-consuming and challenging, especially for indoor ranges with limited space and archers with lower skill levels, as they necessitate precise alignment and larger group sizes at longer distances.
Innovation Solution
A system and method that uses archery parameters to mathematically determine sight settings, allowing for precise selection of a sight tape without the need for shots at long distances, using a computer-readable medium to compare distances and identify the correct tape, enabling accurate sight-in at a single distance for multiple distances, and accommodating non-1:1 ratios between sight and alignment pin movements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional sight tape selection methods are used requiring multiple shots at long distances, then accurate sight-in can be achieved, but the process becomes time-consuming and requires large space
Solution Approach 1:
The system performs preliminary calculations of sight settings using archery parameters (arrow speed, draw weight, draw length, arrow weight) before any shots are taken. By pre-computing the sight tape selection and sight pin positions based on ballistic equations, the system eliminates the need for time-consuming trial shots at multiple distances, while still achieving accurate sight-in.
Solution Approach 2:
The patent replaces the mechanical trial-and-error shooting method with a computational system that uses electronic calculations based on archery parameters. The system substitutes physical shooting practice with mathematical modeling of arrow trajectory, using a processor to compute optimal sight settings from input parameters about the archer's equipment and technique.
2Measurement precision
If traditional sight tape selection methods are used requiring shots at long distances, then accurate sight-in can be achieved, but the difficulty increases for indoor ranges with limited space
Solution Approach 1:
The system changes the operational parameters by accepting archery equipment specifications (draw weight, draw length, arrow speed, arrow weight) as input instead of requiring physical shooting at various distances. This parameter-based approach allows the calculation to be performed independently of the shooting range environment, making the process equally convenient for both indoor and outdoor ranges.
3Measurement precision
If multiple shots at long distances are required for sight tape selection, then precise alignment can be established, but the skill level requirement increases for less skilled archers
Solution Approach 1:
The system performs the alignment precision task automatically through computational calculation rather than requiring the archer to manually achieve precise alignment through repeated shooting. The processor self-determines the correct sight tape and pin positions based on the input parameters, eliminating the need for the archer to possess advanced shooting skills for the sight-in process.
4Measurement precision
If traditional sight-in methods are used requiring multiple shots and adjustments, then accurate sight settings can be achieved, but the quantity of arrows consumed increases
Solution Approach 1:
The system performs preliminary calculation of the correct sight settings before any arrows are shot. By computing the optimal sight tape selection and pin positions in advance based on archery parameters, the system minimizes the number of arrows needed to verify and adjust the settings, thereby reducing arrow consumption while maintaining accuracy.
