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 frequent rifle calibration and increased user burden when used in varying lighting conditions, leading to inefficiencies in hunting scenarios.
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, allowing for interchangeable operation modes and collective adjustment of optical components to maintain reticle alignment during magnification changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If two separate sights (white-light and infrared) are carried with one rifle, then viewing capability in different lighting conditions is improved, but rifle calibration complexity increases due to repeated removal and remounting
Solution Approach 1:
The patent combines white-light and infrared optical paths into a single integrated sight system. The beam combination lens merges both light paths, allowing both viewing modes to be accessed through one rifle mounting, eliminating the need to remove and remount separate sights and perform repeated calibrations.
Solution Approach 2:
The integrated sight system provides multi-functionality by enabling both white-light and infrared viewing capabilities within a single device. The optical switching mechanism allows the user to switch between different viewing modes without changing the mounted sight, making the system universal for different hunting conditions.
2Adaptability or versatility
If two separate sights are carried with one rifle, then viewing capability in different lighting conditions is improved, but user burden increases due to frequent removal and remounting operations
Solution Approach 1:
The patent implements a dynamic optical switching mechanism that allows seamless transition between white-light and infrared modes. The optical switch can be operated without removing the sight from the rifle, enabling quick adaptation to changing lighting conditions during hunting activities.
3Measurement precision
If rifle calibration is performed for each sight removal and remounting, then reticle alignment accuracy is maintained, but time consumption and ammunition waste increase
Solution Approach 1:
The integrated sight system is pre-calibrated during manufacturing to ensure proper reticle alignment for both white-light and infrared modes. This preliminary calibration eliminates the need for repeated field calibration when switching between viewing modes, saving time and ammunition.
4Measurement precision
If two hunting rifles are carried (one with white-light sight, one with infrared sight), then reticle alignment accuracy is maintained, but user burden and cost increase
Solution Approach 1:
The patent merges the functionality of two separate rifles with different sights into a single rifle with an integrated dual-mode sight system. This consolidation maintains reticle alignment accuracy through pre-calibration while reducing the physical burden and cost of carrying and maintaining two separate rifles.
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 multiple rifles and rifle calibrations, and maintaining reticle alignment across different magnification levels.
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 adjusting structure includes a reticle plate, a beam combination lens, and a relay lens assembly 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 of the beam combination lens, and is then transmitted to the relay lens assembly. The reticle plate, the beam combination lens, the relay lens assembly 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.
