Solution Overview
Problem
Conventional dual-wavelength gun aiming collimated beam light source modules suffer from aiming deviation due to parallel arrangement of dual-wavelength collimated light sources, which complicates wavelength selection and usage.
Innovation Solution
A dual-wavelength gun aiming collimated beam light source module design featuring a positioning seat with through holes for laser modules, obliquely arranged reflecting mirrors with specific coatings, and ball-and-socket units for adjustable optical path alignment, ensuring that laser light of one wavelength coincides with the optical path of the other after reflection, thus eliminating aiming deviation and enabling light blending.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If dual-wavelength collimated light sources are arranged in parallel, then users can switch and select collimated light sources with suitable wavelengths, but the different wavelengths have different aiming points causing aiming deviation
Solution Approach 1:
The patent combines two separate wavelength optical paths into a single shared optical path. The first wavelength light source and second wavelength light source both pass through the same objective lens and exit aperture, merging their paths to ensure they share the same aiming point and eliminate aiming deviation while maintaining dual-wavelength capability
Solution Approach 2:
The patent introduces a dichroic mirror to separate and combine optical paths in a multi-dimensional spatial arrangement. The first wavelength light source uses a reflection optical path while the second wavelength light source uses a transmission optical path, allowing both wavelengths to coexist in the same physical space without interference and with identical aiming points
2Adaptability or versatility
If separate visible light and invisible light gun aiming collimated beam light source modules are prepared, then suitable wavelength can be selected for daytime or nighttime use, but the user must prepare two different modules
Solution Approach 1:
The patent merges visible light and invisible light sources into a single integrated module. Both the first wavelength light source (visible) and second wavelength light source (invisible) are housed together with shared optical components including the objective lens and aperture, reducing the system from two separate modules to one unified module while maintaining both daytime and nighttime functionality
Solution Approach 2:
The patent creates a universal light source module that performs multiple functions. The single module can emit both visible light for daytime use and invisible light for nighttime use, eliminating the need for separate specialized modules and providing multi-functional capability in a single device
