Integrated Reticle Adjustment for Multi-Mode Sighting Alignment
Find Innovative SolutionsGenerate Solutions
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
Engineering 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
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.
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.
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
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.
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
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.
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

AI summary
A reticle adjustment structure and a reticle adjustment method thereof, and a multi-mode sighting apparatus. The reticle adjustment structure comprises a reticle (13), a beam combiner (14) and an image inverting lens set (16), which are sequentially arranged along a visible light optical axis, and a display module (40) outside of the visible light optical axis, wherein the beam combiner (14) comprises a first light incident surface and a second light incident surface, which are oppositely arranged and which respectively face the incident direction of a visible light signal and the display module (40); a visible light signal in a target field of view is incident to the first light incident surface of the beam combiner (14) by means of the reticle (13), and is then transmitted to the image inverting lens set (16); information displayed on the display module (40) is incident to the second light incident surface of the beam combiner (14) in the form of an optical signal, and is then reflected to the image inverting lens set (16); and the reticle (13), the beam combiner (14), the image inverting lens set (16) and the display module (40) are connected to each other to form an integral lens set in which the components can move together, such that the adjustment of the whole set is realized during a reticle adjustment process.
