Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current archery sight-setting methods are inefficient and imprecise, requiring long-distance shots and extensive time for setup, especially for multi-pin sights, due to the inability to accurately account for arrow drag and flight trajectory variations, leading to reduced accuracy and increased complexity.
Innovation Solution
The use of portable electronic devices with graphical user interfaces to generate and display precise archery sight marks based on measured arrow drag and time-of-flight data, allowing for real-time adjustments and simplifying the sight-in process by using a single sight mark as a reference for multiple distances.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional archery sight-setting methods are used, then the process can be completed with basic equipment, but the time required for setup increases and accuracy decreases
Solution Approach 1:
The system performs preliminary calculations of arrow trajectory, drag, and time-of-flight using a computational model before the archer actually sets the sights. By pre-calculating the optimal sight settings based on measured arrow parameters, the system eliminates the need for time-consuming trial shots and adjustments at the range, directly resolving the contradiction between accuracy and setup time
Solution Approach 2:
The patent replaces the traditional mechanical trial-and-error sight-setting process with a computational system that uses electronic measurements of arrow drag and time-of-flight combined with mathematical modeling. This substitution of mechanical adjustment with computational calculation achieves higher precision while significantly reducing the time required for setup
2Measurement precision
If traditional trajectory estimation methods are used, then the process is simpler, but the accuracy of point-of-impact prediction decreases
Solution Approach 1:
The system replaces simple trajectory estimation with a computational model that incorporates measured arrow drag and time-of-flight data. By substituting rough estimates with physics-based calculations using electronic measurements, the system achieves superior point-of-impact accuracy while managing complexity through automated computation rather than manual complexity
Solution Approach 2:
The system creates a virtual model of the arrow's flight trajectory based on measured parameters, allowing the archer to simulate and predict point-of-impact before actual shooting. This virtual copy of the flight path enables accurate prediction without requiring complex physical trial shots
3Adaptability or versatility
If multiple sight pins are used for different distances, then versatility is improved, but the complexity of setting up and adjusting the sight increases
Solution Approach 1:
The system provides universal sight-setting capability for multiple distances through a single computational model that can calculate optimal settings for any range. By replacing multiple physical sight pins with a versatile calculation system, the patent achieves multi-distance adaptability while actually simplifying the adjustment process, as the system generates settings for all distances rather than requiring manual adjustment of multiple pins
4Productivity
If theoretical arrow characteristics are used for sight-setting, then the process is faster, but the accuracy decreases due to unaccounted drag variations
Solution Approach 1:
The system replaces theoretical arrow characteristics with actual measured drag and time-of-flight data obtained through electronic sensors. By substituting theoretical models with empirical measurements, the system achieves both speed (through automated calculation) and accuracy (through real data), resolving the contradiction between productivity and precision
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This approach significantly reduces the time and complexity of setting up archery sights, increases accuracy, and allows for precise sight pin settings without the need for long-distance shots, making it suitable for a wider range of archers and facilities.
Implementation Method 1
The effect of gravity on the arrow's flight acts to draw the arrow back toward the ground as the arrow travels from the archer toward the target
Implementation Method 2
the arrow's launch speed and drag also affect the amount of pitch that must be provided at launch to strike a point-of-aim on a target, because both the arrow's drag and its speed effect the time-of-flight from launch to impact
