Rangefinder Display Integrating Virtual Bow Sight Pins
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 movements that can alert targets, leading to missed shots due to the absence of dynamic trajectory indicators showing clear shot information.
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 and movements
Solution Approach 1:
The patent combines the rangefinder display with virtual bow sight pins in a single integrated interface. The computing element generates virtual pins that are superimposed on the optical image, merging the ranging function with the aiming function into one unified display system, eliminating the need for separate devices or multiple operational steps
Solution Approach 2:
The patent introduces a computing element as an intermediary that processes range data from the rangefinder and translates it into virtual bow sight pin positions on the display. This intermediary component bridges the gap between raw range measurement and intuitive visual aiming guidance, enabling seamless integration without directly modifying the physical bow sight
2Productivity
If multiple steps and movements are required to determine clear shot, then the device complexity is reduced, but the loss of time increases
Solution Approach 1:
The system performs preliminary calculations of projectile trajectory and clear shot determination in advance, generating virtual bow sight pins that pre-indicate the aiming point and trajectory clearance before the user takes the shot. This preliminary action eliminates the need for time-consuming manual calculations or multiple measurement steps during the actual shooting sequence
Solution Approach 2:
The display continuously shows virtual bow sight pins and trajectory information as the user moves the rangefinder, providing uninterrupted guidance throughout the aiming process. This continuous feedback eliminates gaps between ranging, calculating, and aiming actions, maintaining a seamless flow from target acquisition to shot execution
3Reliability
If dynamic trajectory indicators are not provided, then the device complexity is reduced, but the reliability deteriorates due to absence of clear shot information
Solution Approach 1:
The system provides immediate visual feedback through virtual bow sight pins that indicate whether the trajectory is clear or obstructed. The display shows affirmative clearance information when the path is open, giving the user confidence and reliable guidance for safe shot determination without requiring complex external verification procedures

AI summary
A system for indicating to a user a clear shot along a projectile trajectory to a target wherein one of the trajectory path indicators indicates a height of the projectile trajectory at a predetermined intermediate range to the target whereby the user is informed regarding whether or not an obstacle is in the projectile trajectory. The system facilitates accurate, effective, and safe firearm and bow use by providing indications regarding obstacles that are between the shooter and target and which may or may not be in the projectile trajectory. The system may indicate a calibrated aiming point, which is the maximum height of the projectile trajectory. Enhanced rangefinders have digital cameras and high-resolution displays. Some embodiments include a weapon scope, a simulation game device, and a mobile smart phone. A method of using the system.
