Solution Overview

Problem

Conventional two-piece firearm sights obstruct the shooter's field of view due to the post or bead of the front sight, interfering with accurate targeting.

Innovation Solution

Designing a firearm sight system with separate front and rear sights featuring U-shaped channels that are equal in size and shape, providing an unobstructed view along the sight line by eliminating the need for a post or bead within a notch, allowing for clear alignment and focus on the target.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a conventional two-piece sight with a post or bead front sight is used, then the sight provides a traditional alignment reference, but the post or bead obstructs the shooter's field of view along the sight line

Engineering Contradiction:
Improvefield of view clarityVSAvoidvisual obstruction by front sight post
Core Design Contradiction:
Ease of operationVSObject-generated harmful factors

Solution Approach 1:

The patent removes the traditional post or bead element from the front sight and extracts only the essential alignment function, replacing it with a channel design that guides the eye without physically obstructing the field of view. The front sight channel is designed to be aligned with the rear sight channel, providing alignment reference while eliminating the harmful obstruction of a solid post.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The sight system is divided into separate front and rear sight channels that can be independently designed and aligned. The front sight channel and rear sight channel are separate components that work together to provide alignment, allowing each to be optimized for its specific function without the constraints of a traditional post-and-notch design.

Inventive Principle:
Principle #1Segmentation

2Measurement precision

If a post or bead front sight is used within a rear sight notch, then alignment reference is provided, but the shooter's ability to focus on the target is interfered with

Engineering Contradiction:
Improveaiming accuracyVSAvoiddistracting obstruction of target focus
Core Design Contradiction:
Measurement precisionVSObject-affected harmful factors

Solution Approach 1:

The patent extracts the alignment reference function from the traditional post-and-notch configuration and relocates it to a channel-based system. The front sight channel and rear sight channel provide the necessary alignment guidance while removing the distracting post element that previously interfered with the shooter's ability to focus on the target.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

Instead of using a solid post that blocks the view, the patent inverts the approach by using open channels that guide alignment through their geometry rather than through physical obstruction. The channels are designed to be aligned with each other, providing alignment reference while allowing clear visibility of the target.

Inventive Principle:
Principle #13The other way round (Inversion)
