Shotgun Sight Plate with Pin and Lead Arcs for Moving Targets
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing shotgun sights are complex and difficult to navigate, rely on target size for aiming, and complicate the process of leveling the gun barrel, making it challenging to hit moving targets quickly and accurately due to changing variables like speed, distance, and angle of flight.
Innovation Solution
A compact, easy-to-attach shotgun sight system featuring a clear plate with a pin and mounting means, including sickle-shaped markings for lead indication, a mid-sight notch for proper head positioning, and adjustable sights to simplify target acquisition and leveling, allowing shooters to use both eyes open or closed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If complex lines and angled indicators are used to provide aiming guidance, then target acquisition capability is improved, but device complexity increases and ease of operation deteriorates
Solution Approach 1:
The patent extracts only the essential aiming information needed by the shooter, removing unnecessary complex lines and angled indicators. The sight presents a simplified view showing primarily the target and basic alignment references, allowing shooters to acquire targets quickly without navigating through excessive indicators.
Solution Approach 2:
Instead of presenting the shooter with complex indicators and requiring them to interpret and navigate through multiple lines and angles, the sight inverts the approach by presenting a simplified view that requires minimal interpretation. The alignment markings are designed to be intuitively understood without complex navigation.
2Adaptability or versatility
If multiple target indicators and lines are provided for different target sizes, then adaptability to different targets is improved, but ease of operation deteriorates due to difficulty in making split second decisions
Solution Approach 1:
The sight provides localized aiming information positioned directly over the target area, showing alignment references and lead indicators precisely where the shooter needs them. This localized presentation eliminates the need to scan across the entire sight picture to find appropriate indicators for different target sizes.
Solution Approach 2:
The sight is pre-configured with fixed alignment markings and lead indicators that are automatically applicable to various target sizes and distances. The markings are positioned and sized to provide appropriate guidance without requiring the shooter to actively select or adjust between multiple indicator sets during the shooting decision process.
3Device complexity
If the existing gun barrel sight is used as the primary sight, then device complexity is minimized, but measurement precision deteriorates due to difficulty in leveling the gun barrel
Solution Approach 1:
The patent introduces an intermediary leveling mechanism that mediates between the shooter's natural sight picture and the actual barrel alignment. This intermediary system provides visual feedback and alignment references that enable precise barrel leveling without adding significant complexity to the overall sighting system.
Solution Approach 2:
The patent replaces complex mechanical leveling mechanisms with optical or visual alignment methods. Instead of relying on mechanical adjustments and physical indicators, the system uses visual references and sight picture alignment to achieve precise barrel leveling, thereby minimizing mechanical complexity while maximizing measurement precision.
4Ease of operation
If shooters rely on visual estimation of target size for aiming, then ease of operation is improved, but measurement precision deteriorates due to difficulty in judging target size at distance
Solution Approach 1:
The sight utilizes visual contrast and distinctive marking patterns that enhance the visibility and perceived size of targets. The alignment markings and reticle elements are designed with specific visual characteristics that help shooters accurately gauge target size and distance through visual cues rather than difficult estimation.
Solution Approach 2:
The sight adds dimensional reference information to the two-dimensional sight picture by incorporating alignment markings, lead indicators, and reference points at known positions. These additional dimensional references enable shooters to more accurately judge target size and distance by comparing the target against the known dimensions of the sight elements.

AI summary
A shotgun sight for mounting to the end of a shotgun barrel comprises a clear plate having a pin extending generally normally from the plate back toward the eye of the shooter and parallel to the axis of the barrel. The plate has a circle surrounding the base of the pin to facilitate proper eye positioning for use of the plate as a sighting device and a dot marked on the plate between the pin and the barrel to serve as an elevation mark. Arcs marked on the plate centered on the pin serve as lead indicators for moving targets.
