Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Notch sights obscure the target picture, are slow to align, and difficult to use in low light conditions and rapid fire situations, especially at long distances from handguns.

Innovation Solution

A firearm sight system with a rear sight portion featuring a circular center and two open triangles, and a front sight portion with a circular non-hollow point, allowing automatic natural alignment and unobstructed target view, with a central aiming hole and lateral windows for improved visibility.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If notch sights are used, then the sight structure is simple and easy to manufacture, but the target picture is obscured and alignment is slow

Engineering Contradiction:

Improvesight structure simplicityVSAvoidtarget acquisition speed

Core Design Contradiction:

Ease of manufactureVSEase of operation

Solution Approach 1:

The sight is divided into two separate components: a rear sight block with a circular aperture and front sight element, allowing independent optimization of each component's function while maintaining manufacturing simplicity

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The circular aperture acts as an intermediary element between the shooter's eye and the target, providing a reference frame that facilitates rapid alignment without obscuring the target picture like traditional notch sights

Inventive Principle:

Principle #24Intermediary (Mediator)

2Device complexity

If notch sights are used, then the sight structure is simple, but the target field of view is obstructed

Engineering Contradiction:

Improvesight structure complexityVSAvoidtarget field of view

Core Design Contradiction:

Device complexityVSArea of stationary object

Solution Approach 1:

The traditional obstructive notch structure is replaced by extracting only the essential alignment function, achieved through a minimal circular aperture that defines the sight picture without blocking the target area

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The sight design transitions from a two-dimensional notch profile to a three-dimensional circular aperture, creating a depth reference that improves alignment precision while minimizing visual obstruction of the target field

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

3Measurement precision

If peep hole sights are used, then the aiming precision is improved, but the sight is difficult to use on handguns and slow in combat situations

Engineering Contradiction:

Improveaiming precisionVSAvoidsight usability on handguns

Core Design Contradiction:

Measurement precisionVSEase of operation

Solution Approach 1:

The aperture size and shape parameters are optimized to provide sufficient precision for handgun distances, unlike traditional peep sights designed for longer ranges, while maintaining a compact form factor suitable for handgun integration

Inventive Principle:

Principle #35Parameter changes

AI summary

A gun sight system including a front sight portion and a rear sight portion. The rear sight portion comprises a circular cylinder sided and formed by incomplete triangles pointing to circular cylinder from each side. In some embodiments, the front sight portion comprises a non-hollow circular cylinder. When the front sight circle is aligned horizontally and vertically to the center of the rear sight, an image of two circles is formed for the user and a target is placed in the center of the point of the circle of the front sight.
