Solution Overview

Problem

Existing firearm sight adjustment systems face challenges in precise vertical alignment due to the mismatch between linear spring force and arc motion, leading to binding issues and difficulty in achieving precise positioning.

Innovation Solution

A magnetically stabilized sight assembly with a pivotally attached swing member and oppositely charged magnets that repel each other to maintain the plate's vertical position, allowing precise adjustment without the binding issues associated with linear springs.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a linear spring is used to bias the swing member vertically, then the sight can be adjusted vertically, but the spring binds due to mismatch between linear force and arc motion

Engineering Contradiction:

Improvevertical adjustmentVSAvoidbinding

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The patent replaces the linear spring mechanism with a magnetic biasing component that exerts force through a linkage system. The magnetic component interacts with a pivot point to create a curved path of motion that matches the arc movement of the swing member, eliminating binding while maintaining vertical adjustment capability.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent introduces a curved linkage mechanism that transforms the linear magnetic force into follow-the-arc motion. The linkage includes a curved surface or pivot arrangement that guides the swing member through its arc of motion while the magnetic component remains positioned to exert consistent biasing force throughout the movement range.

Inventive Principle:

Principle #14Spheroidality (Curvature)

2Adaptability or versatility

If a pivot pin is used to attach the swing member, then the swing member can pivot, but the swing member moves in an arc rather than linearly

Engineering Contradiction:

Improvepivot motionVSAvoidvertical alignment

Core Design Contradiction:

Adaptability or versatilityVSManufacturing precision

Solution Approach 1:

The patent replaces the traditional pivot pin mechanism with a magnetic biasing system that uses a linkage to control the swing member's motion. The magnetic component interacts with a pivot point to create a curved path that naturally follows the arc of motion, improving alignment precision while maintaining the pivot functionality.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent introduces a linkage mechanism as an intermediary between the magnetic biasing component and the swing member. This linkage includes a curved surface or pivot arrangement that mediates the force transmission, converting the magnetic force into appropriate arc motion while maintaining precise vertical alignment throughout the movement range.

Inventive Principle:

Principle #24Intermediary (Mediator)

3Force

If the spring exerts vertical force, then the swing member can be biased vertically, but the force does not match the arc movement path

AI summary

A sight mechanism for firearms such as pistols, rifles and the like. The sight mechanism includes a sight member that has a rear sight that is vertically adjusted. The sight member can be mounted on a vertically moveable member that has a fixing member that sets the vertical position of the sight member. The vertically moveable member may, without limitation, be a pivoting member. The sight mechanism includes magnets that bias the vertical member against the fixing member so that the magnets maintain the sight at the vertical position defined by the fixing member.
