Integrated Imaging Rangefinder for Sighting Telescopes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional sighting apparatuses face challenges in accurately estimating target distances due to subjectivity and the need for complex calculations when using laser rangefinders separate from the sighting device, making the process cumbersome and prone to errors.
Innovation Solution
An imaging rangefinder is integrated with a sighting telescope, featuring a power supply, control module, imaging module, ranging imaging module, and display module, which combines image data from the sighting telescope with ranging information, allowing for direct observation of distance and aiming points through an eyepiece system, simplifying the process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a laser rangefinder is located outside the sighting apparatus, then ranging accuracy is improved, but device complexity and ease of operation deteriorate due to the need for separate observation and calculation
Solution Approach 1:
The patent integrates the laser rangefinder and sighting apparatus into a single unified device. The laser emitting unit, laser receiving unit, and sighting telescope are combined in one integrated structure, allowing simultaneous observation and ranging without separate devices or manual calculation steps.
Solution Approach 2:
The integrated device performs multiple functions simultaneously: the sighting telescope provides visual targeting while the laser units perform distance measurement, and both functions are combined in a single apparatus that can be mounted on the firearm, eliminating the need for separate ranging and sighting devices.
2Measurement precision
If a laser rangefinder is located outside the sighting apparatus, then ranging accuracy is improved, but ease of operation deteriorates due to the need for back-and-forth observation and comprehensive calculation
Solution Approach 1:
The patent combines the sighting and ranging functions into a single integrated device with a unified optical path, allowing the user to observe through the sighting telescope and obtain ranging data simultaneously without switching between separate devices or performing manual calculations.
Solution Approach 2:
The integrated device provides immediate feedback by displaying ranging information directly through the sighting apparatus interface, allowing the user to see both the target through the telescope and the measured distance data simultaneously, eliminating the need for separate observation and manual calculation steps.
3Device complexity
If conventional optical sighting apparatus uses scribe lines on a reticle for distance estimation, then device complexity is reduced, but measurement precision deteriorates due to subjectivity and limitation
Solution Approach 1:
The patent replaces the mechanical/optical scribe line reticle system with an electronic laser ranging system. Instead of using physical markings on a reticle that require subjective interpretation, the system uses laser time-of-flight measurement to automatically calculate and display precise distance data.
Solution Approach 2:
The patent introduces a laser beam as an intermediary between the sighting apparatus and the target for distance measurement. The laser emitting unit sends a laser beam to the target, and the laser receiving unit captures the reflected beam, using this intermediary to enable precise electronic distance measurement rather than relying on visual estimation through reticle markings.
