Rangefinder Reticle with Trajectory Pins for Clear Shot Assessment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional rangefinders and bow sights lack a direct correlation between the displayed range information and the user's individual bow sight, requiring multiple steps and time to assess clear shots, which can result in missed opportunities due to target movement or interference from obstacles.
Innovation Solution
A rangefinder device with a display that dynamically indicates projectile trajectories, providing clear shot information by correlating range data with the user's bow sight pins, allowing for accurate and safe firearm or bow use by indicating obstacles along the trajectory.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional rangefinders display range information separately from bow sight pins, then the device complexity is reduced, but the ease of operation deteriorates due to requiring multiple steps to assess clear shots
Solution Approach 1:
The patent combines the rangefinder display with the bow sight pins into a single integrated reticle system. The processor generates a reticle that includes both the traditional crosshairs and trajectory indicators (pin 20, pin 40, pin 60) that directly correlate with the user's bow sight settings. This merging eliminates the need for separate devices or multiple assessment steps, allowing the user to view all trajectory information through the same optical viewfinder.
Solution Approach 2:
The reticle serves multiple functions simultaneously: it provides traditional aiming crosshairs, displays trajectory indicators for different distances (20 yards, 40 yards, 60 yards), shows the actual target range, and indicates whether the shot path is clear or obstructed. This multi-functional design replaces what previously required multiple separate tools or manual calculations.
2Measurement precision
If the display shows detailed trajectory information, then the measurement precision is improved, but the loss of time increases due to processing and displaying multiple data points
Solution Approach 1:
The processor pre-calculates and prepares the reticle display with all necessary trajectory information before the user needs it. When the rangefinder measures the target distance, the system immediately generates the corresponding reticle with appropriate pin positions and trajectory indicators already computed based on the measured range and stored ballistic data.
Solution Approach 2:
The system creates a visual copy of the physical trajectory path by displaying intermediate points (pin 20, pin 40) that represent where the projectile will be at different distances. These digital markers replicate the actual ballistics without requiring the user to perform manual calculations or use separate tools.
3Reliability
If the system correlates range data with individual bow sight settings, then the reliability is improved, but the device complexity increases due to calibration requirements
Solution Approach 1:
The system allows users to input their specific bow parameters (draw weight, arrow weight, sight pin positions) and stores these as calibration data. The processor uses these parameters to generate accurate trajectory calculations specific to each user's equipment. This parameter-based approach enables customization without requiring complex mechanical adjustments or calibration procedures.
Data Source
AI summary
An improved display provides information regarding a projectile trajectory so that a user is informed whether or not there is a clear shot. The improved display provides one or more path indicators shown over the cross hairs. In some embodiments, an intermediate point in the projectile trajectory is an aiming point and is indicated in relation to the visualized target. The rangefinder device is calibrated to a bow having a bow sight, for example, having a twenty-yard pin. The aiming point is display showing the intermediate point in the projectile trajectory that corresponds with the bow sight pin. The archer places the bow sight pin on the point visualized in the rangefinder device.
