Solution Overview

Problem

The front sight on traditional 1911 handguns moves during firing, complicating aiming.

Innovation Solution

A modular firearm block with a pin and pin connector system that attaches to the frame, providing a stationary sight and acting as a muzzle brake to manage recoil and muzzle rise.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the front sight is mounted on the moving slide, then the sight moves during firing, but this makes aiming more difficult

Engineering Contradiction:
Improvesight positioning flexibilityVSAvoidaiming stability
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The front sight assembly is segmented from the moving slide and mounted on a separate stationary block that is fixed to the frame. This allows the sight to be decoupled from the moving components, ensuring it remains stationary during firing while maintaining the ability to independently position and adjust the sight assembly.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The front sight is extracted from the moving slide structure and relocated to a dedicated stationary block mounted on the frame. This extraction removes the sight from the moving components, ensuring it remains fixed during operation while allowing independent mounting and adjustment of the sight assembly.

Inventive Principle:
Principle #2Taking out (Extraction)

2Ease of operation

If a modular block system with pin and pin connector is used, then the sight block can be easily attached and detached, but the device complexity increases

Engineering Contradiction:
Improveblock attachment easeVSAvoidattachment mechanism complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The attachment mechanism transitions from a permanent fixed connection to a dynamic removable connection using pins and pin connectors. This allows the block to be easily attached and detached while maintaining structural integrity during use, balancing ease of operation with controlled complexity through standardized fastening components.

Inventive Principle:
Principle #15Dynamics
