Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional dot sighting devices for heavy machine guns face challenges in providing binocular vision, preventing parallax, rapid target acquisition, and accommodating varying bullet paths due to distance, and are limited by monocular vision and single reticle designs that do not account for target characteristics.
Innovation Solution
A dot sighting device with a wider reflection mirror for binocular vision, a reticle selection unit for target-specific reticles, and a bullet path adjustment mechanism to account for distance and target characteristics, utilizing a doublet reflection mirror with aspheric surfaces to minimize parallax and aberrations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If a narrow reflection mirror is used in conventional dot sighting devices, then the device structure is compact, but binocular vision is prevented and parallax occurs
Solution Approach 1:
The patent transitions from monocular to binocular vision by increasing the reflection mirror width to exceed the distance between user's eyes. This dimensional change in the mirror width enables both eyes to simultaneously view the dot image and target, eliminating parallax and providing stereoscopic vision capability.
2Adaptability or versatility
If a single reticle design is used, then the device structure is simple, but it cannot account for varying target characteristics and distances
Solution Approach 1:
The patent introduces a rotatable reticle selection unit that allows dynamic switching between multiple reticle designs (crosshair, dot, ring) and multiple magnification levels. This dynamic mechanism enables the user to adapt the sighting device to different target characteristics and distances by rotating to select the appropriate reticle configuration.
Solution Approach 2:
The reticle system is segmented into multiple independent reticle designs (first reticle with crosshair, second reticle with dot, third reticle with ring) and multiple magnification levels. Each reticle type is optimized for specific target characteristics, allowing the user to segment the sighting task into different reticle selections based on target type and distance.
3Measurement precision
If no bullet path adjustment mechanism is provided, then the device structure is simple, but sighting accuracy deteriorates with varying distances
Solution Approach 1:
The patent pre-calculates and pre-configures multiple bullet path compensation values corresponding to different target distances. The adjustment mechanism allows the user to pre-select the appropriate compensation value before firing, eliminating the need for complex real-time calculations and enabling rapid sighting while maintaining accuracy at various distances.
4Productivity
If traditional line of sight alignment is used, then the sighting device can provide detailed target information, but rapid target acquisition is hindered by alignment complexity
Solution Approach 1:
The patent extracts the complex line of sight alignment process and replaces it with a simplified dot-based aiming system. The dot image serves as a direct aiming point that can be rapidly aligned with the target center without requiring precise alignment of front and rear sights, significantly reducing the time and complexity of target acquisition.
