Firearm Scope with Range-Dependent Aim Points
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional sight systems, including scopes, are cumbersome and time-consuming to adjust for accurate long-distance shooting, as they typically require manual adjustments to indicate a single aim point for projectile impact at varying distances.
Innovation Solution
A scope with a plurality of range-dependent point-of-impact indicators, featuring a housing with a light projector, electronics module, and user-operable controls, allowing for adjustable aim points in intensity, size, color, and shape, which can be individually adjusted for different projectile distances, and optionally includes a digital multi-pixel device and beam splitter for precise optical alignment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional scopes with single aim point are used, then the scope structure is simple, but the adjustment process is cumbersome and time-consuming for long-distance shooting
Solution Approach 1:
The scope divides the single aim point function into multiple range-specific aim points (first aim point for first distance, second aim point for second distance, etc.). Each aim point can be independently activated based on the shooting distance, eliminating the need for manual realignment and reducing adjustment time.
Solution Approach 2:
The scope transitions from a static single aim point to dynamic multiple aim points that can be selectively activated. The system allows the user to switch between different aim points corresponding to different distances, making the scope adaptable to varying shooting conditions without physical realignment.
2Adaptability or versatility
If multiple light-blocking reticules are used for different distances, then range coverage is improved, but the device complexity increases
Solution Approach 1:
The patent replaces traditional mechanical light-blocking reticules with a digital display system. Multiple aim points are generated electronically through a display device controlled by a processor, eliminating the need for complex mechanical adjustment mechanisms while providing the same range coverage functionality.
Solution Approach 2:
The scope integrates multiple functions into a single system: distance measurement (via range finding), automatic aim point selection, and display control. The processor coordinates these functions to automatically present the appropriate aim point based on the measured distance, reducing overall system complexity despite the increased versatility.
3Adaptability or versatility
If manual adjustment of aim point location is allowed, then flexibility for different distances is achieved, but the adjustment process becomes cumbersome
Solution Approach 1:
The scope performs automatic aim point selection and positioning based on the measured distance. The processor automatically calculates and positions the appropriate aim point without requiring manual adjustment by the user, making the system self-servicing and eliminating the cumbersome manual adjustment process while maintaining full adaptability to different distances.
Solution Approach 2:
The system uses feedback from the range finding device to automatically adjust the aim point position. The processor receives distance information and automatically positions the correct aim point on the display, creating a closed-loop system that eliminates manual intervention while maintaining flexibility for different shooting distances.
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
Enables quick and precise adjustment of aim points for accurate projectile impact at various distances, improving shooting accuracy and efficiency by providing multiple, user-adjustable aim points corresponding to specific distances, accounting for environmental and projectile variations.
Implementation Method 1
A light projector and an electronics module are structurally and operably associated with the housing. An optical system is structured to cause propagation of light from the light projector in a direction substantially in agreement with the first optical axis and thereby to present a first aim point to the eye of a user.
Implementation Method 2
One preferred optical system includes a beam splitter carried at a distal end of the housing and disposed in a plane having its normal oriented parallel to the first optical axis of the housing.

AI summary
A scope having a plurality of range-dependent, point-of-impact indicators (aim points), and methods for use of that scope. Such aim points are superimposed on the user's field of view of a conventional scope. A preferred embodiment may be coupled to a conventional scope. Embodiments include an auxiliary light projector that presents at least one aim point disposed in a user's field of view, and the aim point(s) is/are adjustable for elevation and windage. Aim points may also be adjusted in size, color, shape, and intensity.
