Solution Overview

Problem

Existing sighting devices, such as single-light-path white-light and infrared sights, are limited in functionality and require frequent rifle calibration and increased user burden when used in varying lighting conditions, leading to inefficiencies in hunting scenarios.

Innovation Solution

A reticle adjusting structure with a beam combination lens and relay lens assembly, integrated with a white-light aiming assembly, infrared module, and laser range-finding module, allowing for multiple operation modes and collective adjustment to maintain the reticle at the central field of view during magnification changes.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a hunter carries two sights and one hunting rifle to use white-light sight in daytime and infrared sight in nighttime, then the functionality for different lighting conditions is improved, but the device complexity and operation burden increase due to repeated rifle calibration and frequent removal and remounting of sights

Engineering Contradiction:
Improvefunctionality for different lighting conditionsVSAvoiddevice complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent combines the white-light sight and infrared sight into a single integrated sight assembly that can be mounted on one rifle. The sight switch assembly enables switching between white-light and infrared modes without removing or remounting different sights, thereby merging the functionality of two separate sights into one unified device while eliminating the need for repeated calibration.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The integrated sight assembly provides multi-functionality by incorporating both white-light and infrared sighting capabilities in a single device. The sight switch assembly allows the user to select between different lighting conditions (daytime/nighttime, clear/smoky environments), making the single sight universal for various hunting scenarios without requiring multiple specialized sights.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If a hunter carries two sights and two hunting rifles with different sights mounted, then the adaptability to different lighting conditions is improved, but the user burden and cost increase due to carrying multiple rifles

Engineering Contradiction:
Improveadaptability to different lighting conditionsVSAvoiduser burden
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The patent merges the functionality of two separate rifles with different sights into a single rifle equipped with an integrated sight assembly. The sight switch assembly enables the single sight to perform the functions of both white-light and infrared sights, thereby eliminating the need to carry and switch between two rifles while maintaining adaptability to different lighting conditions.

Inventive Principle:
Principle #5Merging (Combining)

3Measurement precision

If the reticle position is adjusted during magnification changes in multi-mode sighting, then the visualization accuracy is improved, but the device complexity increases due to additional adjustment mechanisms

Engineering Contradiction:
Improvereticle positioning accuracyVSAvoidadjustment mechanism complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent combines the reticle adjustment function with the magnification adjustment function into a single integrated adjustment mechanism. When the magnification is changed, the reticle position is automatically adjusted along with it, ensuring the reticle remains centered in the field of view. This merging of functions achieves precise reticle positioning without requiring separate complex adjustment mechanisms.

Inventive Principle:
Principle #5Merging (Combining)

Applied Scientific Principles

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

Function Achieved in This Case

Enables seamless switching between white-light and infrared modes with a single rifle, reducing the need for rifle recalibration and user burden, while maintaining clear visualization and distance measurement capabilities across different lighting conditions.

Implementation Method 1

A visible light signal of a target field of view passes through the reticle plate to get incident on the first light entry surface of the beam combination lens, and is then transmitted to the relay lens assembly; a message displayed on the display module transmits, in the form of an optical signal, onto the second light entry surface of the beam combination lens, and is then reflected to the relay lens assembly
