Dual Sight Scope With Tilted Eyepiece For Ergonomic Magnification Switching

Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing telescopic sights for firearms require manual power changes that are slow and ergonomic, and combining separate optical products forces users to move their head up and down to switch magnifications, which is uncomfortable and reduces precision.

Innovation Solution

A dual-sight scope with a tilted eyepiece and a secondary sight that allows for minimal head and eye movement, featuring an elevation adjustment mechanism located out of the secondary sighting line to prevent obstruction and enable quick switching between optical systems.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If manual power changing zoom systems are used to provide fitting magnifications for varying distances, then the scope can accommodate different ranges, but the power change process becomes slow and inconvenient

Engineering Contradiction:

Improvemagnification adaptabilityVSAvoidpower change time

Core Design Contradiction:

Adaptability or versatilityVSLoss of time

Solution Approach 1:

The scope is divided into two separate optical systems (primary telescopic sight and secondary open sight) that can be independently used. This segmentation allows the user to switch between magnified and non-magnified views without mechanical adjustment, eliminating the time-consuming zoom mechanism while maintaining adaptability to different shooting distances.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The scope housing integrates both a primary telescopic sight and a secondary open sight, creating a multi-functional device. The secondary sight serves as both an independent optical system and a reference for quick switching, allowing the scope to handle varying distances without requiring power changes.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If two separate optical products are combined by means of mounts, then magnification switching is possible, but the user must move head up and down between exit pupils which is not ergonomic

Engineering Contradiction:

Improvemagnification switching capabilityVSAvoidhead movement requirement

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

The secondary open sight is integrated directly into the scope housing structure, merging the two optical systems into a single unified device. This integration positions the exit pupils at ergonomically aligned locations, eliminating the need for excessive head movement while maintaining the ability to switch between magnification levels.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The design positions the secondary sight's exit pupil at a height that aligns with the primary sight's exit pupil in the vertical dimension, creating a straight-line eye path. This dimensional alignment eliminates the need for up-and-down head movement, making the switching operation ergonomic while preserving magnification versatility.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

3Measurement precision

If elevation adjustment mechanism is added to adjust zeroed-in position, then accuracy is improved, but it may impede the secondary sighting line

Engineering Contradiction:

Improvezeroing accuracyVSAvoidsecondary sight usability

Core Design Contradiction:

Measurement precisionVSEase of operation

Solution Approach 1:

The elevation adjustment mechanism is extracted from the traditional position that would block the secondary sight's line of sight. By relocating the adjustment mechanism to a position that does not impede the secondary sighting line, the patent maintains both zeroing accuracy and uninterrupted access to the secondary open sight.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The elevation adjustment mechanism is positioned with specific local placement considerations, where the adjustment components are located in areas that do not interfere with the secondary sight's optical path. This localized positioning ensures that the zeroing function operates effectively while the secondary sight remains fully accessible.

Inventive Principle:

Principle #3Local quality

AI summary

To enable a user to quickly adjust power ranges of a scope for firearms, a scope may be provided with a primary sight having a primary sighting line and a secondary sight having a secondary sighting line. The primary sight may include a plurality of optical elements disposed within the first housing and an elevation adjustment mechanism for adjusting a zeroed-in position of the primary sight. To prevent impedance of the secondary sighting line, the elevation adjustment mechanism may be located laterally of the primary sight rather than in the conventional position above the primary sight.
