Solution Overview
Problem
Long-range optical devices face challenges in integrating optical, mechanical, and electronic components efficiently, particularly in maintaining a compact size and ensuring clear visibility of target marks under varying light conditions, while managing limited battery power and minimizing component interference during adjustments.
Innovation Solution
The device incorporates a lens-reversing system with a movably mounted front objective lens system, a joint in the objective housing, and an opto-electronic display device with a LCoS display, allowing for adjustable target marks and high-contrast image superimposition, while maintaining a compact design and enhancing recoil resistance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If electronic components (display device, laser rangefinder, control unit) are integrated into the long-range optical device, then functionality and information display are improved, but device complexity and space requirements increase
Solution Approach 1:
The patent combines multiple electronic components (display device, laser rangefinder, control unit) into a single integrated long-range optical device. The display device is positioned in the observation beam path to overlay information on the viewed scene, while the laser rangefinder and control unit are housed within the same structure, sharing common optical and mechanical resources.
Solution Approach 2:
The optical components serve multiple functions: the objective lens and observation beam path are used both for viewing the remote scene and for the laser rangefinder measurements. The display device simultaneously presents visual information and ranges data. This multi-functionality reduces the need for separate dedicated components for each function.
2Illumination intensity
If a LCoS display device is used for high-contrast image superimposition, then image quality and visibility are improved, but power consumption increases
Solution Approach 1:
The LCoS display device operates with periodic refresh cycles rather than continuous operation. The control unit updates the display at specific intervals based on when range measurements are completed and when information changes are needed, allowing the display to enter low-power states between updates while maintaining visibility during active use.
3Ease of operation
If the front objective lens system is mounted movably in a joint, then aiming adjustment and target mark alignment are improved, but mechanical complexity increases
Solution Approach 1:
The objective lens system is divided into a front objective lens system and a rear objective lens system, with the front system mounted movably in a joint structure. This segmentation allows the front system to be independently adjusted for aiming and target mark alignment while the rear system remains relatively fixed, simplifying the adjustment mechanism compared to moving the entire lens assembly.
4Volume of moving object
If multiple components are integrated in a compact housing, then device portability is improved, but component interference and manufacturing difficulty increase
Solution Approach 1:
The patent employs a nested arrangement where the display device is positioned within the observation beam path, the laser rangefinder components are housed within the same optical tube, and the front objective lens system is nested within a joint structure that is itself part of the objective housing. This nested configuration maximizes space utilization while maintaining component accessibility for manufacturing and assembly.
