Solution Overview

Problem

Conventional laser sights on firearms require large dimensions, reduce water resistance, and have complex varifocal mechanism designs due to a fixed erecting system, making windage and elevation adjustments cumbersome and difficult.

Innovation Solution

A laser sight design with a movable erecting system and an adjusting member that modifies the posture of the laser rangefinder within the housing, allowing for windage and elevation adjustments without moving the objective module, thereby increasing water resistance and simplifying varifocal mechanisms.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the objective module is made movable to enable windage and elevation adjustments, then the adjustment capability is improved, but the device complexity and dimensions increase

Engineering Contradiction:

Improvewindage and elevation adjustment capabilityVSAvoidvarifocal mechanism design complexity

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

Instead of moving the objective module for adjustments, the patent inverts the approach by making the erecting system movable while keeping the objective module fixed. The adjusting member moves the erecting system relative to the objective module, achieving windage and elevation adjustments without complicating the varifocal mechanism.

Inventive Principle:

Principle #13The other way round (Inversion)

Solution Approach 2:

The patent segments the adjustment function from the objective module and assigns it to the erecting system. By separating the adjustment mechanism (adjusting member) from the objective module, the varifocal design remains simple while adjustment capability is maintained through movement of the erecting system.

Inventive Principle:

Principle #1Segmentation

2Device complexity

If the erecting system is fixed to the housing, then the structure is simplified, but the adjustment mechanism requires large dimensions and reduces water resistance

Engineering Contradiction:

Improveerecting system structure simplicityVSAvoidwater resistance

Core Design Contradiction:

Device complexityVSObject-affected harmful factors

Solution Approach 1:

The patent transforms the static erecting system into a dynamic one by enabling it to move relative to the objective module through the adjusting member. This dynamic configuration allows compact adjustment mechanisms that do not compromise water resistance, as the moving erecting system can be sealed and integrated within the housing.

Inventive Principle:

Principle #15Dynamics

3Ease of operation

If the objective module is made movable for adjustments, then the adjustment range is improved, but the water resistance is reduced

Engineering Contradiction:

Improveadjustment rangeVSAvoidwater resistance

Core Design Contradiction:

Ease of operationVSObject-affected harmful factors

Solution Approach 1:

Instead of moving the objective module which would compromise water resistance, the patent inverts the approach by moving the erecting system while keeping the objective module fixed and sealed within the housing. This maintains water resistance while achieving the required adjustment range through erecting system movement.

Inventive Principle:

Principle #13The other way round (Inversion)

AI summary

A laser sight is disclosed, including a housing which defines a first central axis, an objective module, an eyepiece, an erecting system, and an adjusting member. The objective module is fixed to a first end of the housing, and the eyepiece is fixed to a second end of the housing, opposite to the first end. The erecting system is movably disposed between the objective module and the eyepiece and comprises a laser rangefinder defining a second central axis. The adjusting member is movably disposed on the housing and connected to the erecting system. During windage and elevation adjustments, the adjusting member moves with respect to the housing and impels the laser rangefinder, such that the first and second axes form an included angle.
