Weapon Sight With Horizontally Spaced Indicia
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional projectile weapon sighting systems require time-consuming and error-prone target ranging and indicia alignment, especially in quick or moving target scenarios, leading to inaccuracies.
Innovation Solution
A sight system that simultaneously adjusts for windage and elevation by using horizontally spaced indicia that bracket the target, allowing the shooter to align the weapon without estimating the range, with adjustable configurations for different projectile speeds and target sizes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional ranging and indicia alignment methods are used, then elevation adjustment is achieved, but shooting time increases and accuracy decreases due to estimation errors
Solution Approach 1:
The sight system divides the target into multiple horizontal zones using several horizontally-spaced indicia (first, second, third indicia). Each indicia corresponds to a specific target zone, allowing the shooter to quickly identify and align with the appropriate zone without performing complex ranging calculations. This segmentation enables rapid selection of the correct alignment reference based on the visual appearance of the target.
Solution Approach 2:
The sight system pre-calculates and pre-positions multiple indicia at different horizontal locations to correspond with different target zones and distances. These indicia are arranged in advance according to known projectile trajectories and drop characteristics. When the shooter views the target, the preliminary arrangement of indicia allows immediate alignment without requiring real-time range estimation or calculation, thus eliminating shooting time loss while maintaining accuracy.
2Productivity
If traditional ranging methods are used, then distance estimation is performed, but alignment accuracy decreases due to human error in estimation and adjustment
Solution Approach 1:
The sight system enables the target itself to provide the alignment information. The shooter simply observes which horizontal zone of the target is visible and aligns the corresponding indicia with that zone. The target's own position and size in the field of view serve as the reference, eliminating the need for separate ranging operations and human judgment about distance. This self-service approach allows rapid shooting while maintaining accuracy because the alignment is directly based on visual observation of the target rather than estimation.
3Adaptability or versatility
If multiple indicia are added for different ranges, then adaptability improves, but device complexity increases
Solution Approach 1:
The sight system uses a single multi-functional indicia assembly that serves all ranging functions. The first, second, and third indicia are integrated into one structure that can be positioned to cover multiple target zones and distance ranges. This unified indicia assembly provides universal adaptability for different shooting scenarios without requiring separate sighting devices for each range, thus avoiding excessive device complexity while maintaining versatility.

AI summary
A sight configured to properly align a weapon in the left and right direction and in the vertical direction with respect to a target without the need to separately range the target. In particular, once the shooter aligns indicia on the site with structure on the target the weapon is properly aligned and ready firing. Knowledge of the distance between the shooter and the target is not necessary to adjust for projectile drop. Related method of use and manufacture are also provided.
