Rangefinder Trajectory Display for Bow Aiming
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional rangefinders do not provide real-time information on projectile trajectories, requiring users to manually range targets and obstacles, leading to inefficiencies and increased chances of missing shots due to the lack of correlation between rangefinder displays and individual bow sights.
Innovation Solution
A rangefinder device with a display that dynamically indicates projectile trajectories, using a range sensor and tilt sensor to provide clear shot information, including path indicators and obstacle positions, calibrated to match individual bow sights, allowing for accurate and safe firearm and bow use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If conventional rangefinders are used to manually range targets and obstacles, then users can obtain distance information, but the process is time-consuming and lacks real-time trajectory information
Solution Approach 1:
The system pre-calculates and displays the projectile trajectory path before the shot is taken. By showing the anticipated trajectory and intermediate points in advance, the user can plan the shot without time-consuming manual calculations or multiple rangefinding operations during the aiming process.
Solution Approach 2:
The display creates a visual copy or representation of the projectile's flight path by displaying intermediate points along the trajectory. This visual copy allows the user to see where the projectile will be at various distances without actually firing, providing trajectory information that would otherwise require multiple manual rangefinding operations to determine.
2Adaptability or versatility
If fixed reticles are used in scopes, then the display is simple, but the reticles do not dynamically adjust to provide precise aiming information for specific ranges
Solution Approach 1:
The display dynamically adjusts the shown trajectory and intermediate points based on the actual range to the target. As the range changes, the display updates to show the appropriate trajectory path and intermediate positions, making the system adaptable to different shooting scenarios without requiring manual reticle adjustments.
Solution Approach 2:
The system uses feedback from the rangefinder to automatically adjust the displayed trajectory information. The display receives range data and automatically recalculates and shows the appropriate intermediate points and trajectory path, eliminating the need for fixed reticles while maintaining simple operation for the user.
3Productivity
If multiple rangefinding operations are performed to check obstacles along the trajectory, then obstacle positions can be determined, but the process increases time loss and reduces shooting efficiency
Solution Approach 1:
The system performs the obstacle checking function in advance by displaying the complete trajectory path and intermediate points before the shot is taken. This preliminary visualization allows the user to identify potential obstacles along the path without needing to perform separate rangefinding operations for each intermediate point, thereby improving shooting efficiency.
Solution Approach 2:
The single rangefinding operation serves multiple functions: it determines the target distance, calculates the complete trajectory path, identifies intermediate points, and checks for potential obstacles along the entire path. This multi-functionality eliminates the need for multiple separate rangefinding operations, significantly reducing time loss while maintaining comprehensive obstacle awareness.

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 trajectory path indicator shown over 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. A rangefinder device is calibrated to a weapon having a sight, such as a bow sight. The aiming point is displayed showing the intermediate point in the projectile trajectory that corresponds with a pin in the bow sight. The rangefinder device may be calibrated using a calibration sheet. The display may include a level. The trajectory path indicator shows the aiming point, which is the highest point in the projectile trajectory as perceived by the user.
