Integrated Reticle Adjustment for Multi-Mode Sighting Optics
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current sighting devices, such as single-light-path white-light and infrared sights, are limited in functionality and require tedious rifle recalibration and increased burden for hunters needing both types for day and night hunting, with no effective solution for seamless switching between modes.
Innovation Solution
A multi-mode sighting device with a reticle adjusting structure that integrates a white-light aiming assembly, infrared module, and laser range-finding module, using a beam combination lens and display module to allow seamless switching between white-light, infrared, and laser modes, with a single rifle calibration.
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 during daytime and infrared sight during nighttime, then the functionality for different hunting conditions is improved, but the device complexity and the need for repeated rifle calibration increase
Solution Approach 1:
The patent combines white-light and infrared sighting functions into a single integrated sight device that can be mounted on one rifle. The device includes both a white-light optical path and an infrared optical path, allowing the user to switch between modes without carrying multiple separate sights and rifles, thereby reducing complexity while maintaining versatility.
Solution Approach 2:
The integrated sight device performs multiple functions: it can operate as a white-light sight during daytime, as an infrared sight during nighttime, and provides both functions simultaneously in combination mode. This multi-functionality eliminates the need for separate dedicated sights for different hunting conditions.
2Adaptability or versatility
If a hunter carries two sights and two hunting rifles with different sights mounted, then the adaptability for day and night hunting is improved, but the weight and burden on the user increase
Solution Approach 1:
The patent merges white-light and infrared sighting systems into a single integrated device that mounts on one rifle. This consolidation significantly reduces the total weight compared to carrying two separate rifles with different sights, while maintaining the ability to hunt effectively during both daytime and nighttime.
3Adaptability or versatility
If frequent removal and remounting of sights on the rifle is performed to swap between white-light and infrared sights, then the adaptability is improved, but the time consumption and loss of time increase
Solution Approach 1:
The integrated sight device combines both white-light and infrared functionalities in one unit that mounts on the rifle once. The user can switch between viewing modes electronically or mechanically within the same mounted device, eliminating the need for physical removal and remounting of separate sights, thereby saving significant time.
4Measurement precision
If rifle calibration is performed multiple times when swapping sights, then the accuracy is maintained, but the productivity and hunting efficiency decrease
Solution Approach 1:
The integrated sight device performs rifle calibration only once when initially mounted on the rifle. Since both white-light and infrared functions are contained within the same calibrated optical system, the calibration remains valid for both modes, eliminating the need for repeated calibration procedures and maintaining hunting efficiency.
5Adaptability or versatility
If separate white-light and infrared sights are used, then the specialized functionality for each condition is improved, but the ease of operation and user convenience worsen
Solution Approach 1:
The integrated sight device combines white-light and infrared capabilities in one unit with a unified mounting system and single calibration procedure. Users simply select the desired viewing mode without needing to physically swap devices or perform additional calibration, significantly improving ease of operation while maintaining specialized functionality for different hunting conditions.

AI summary
A reticle adjusting structure includes a reticle plate, a beam combination lens, and a magnification variation lens set arranged in sequence along a visible-light optical axis, and a display module arranged outside of the visible-light optical axis. The beam combination lens includes a first light entry surface and a second light entry surface that are arranged opposite to each other and respectively face a visible light signal incidence direction and the display module. A visible light signal of a target field of view passes through the reticle plate to get incident on the first light entry surface, and is then transmitted to the magnification variation lens set. The reticle plate, the beam combination lens, the magnification variation lens set and the display module are interconnected together to form an integrated lens set that is collectively movable together, in order to realize collective adjustment during a reticle adjusting course.
