Optical Observation Device with Integrated Navigation Display
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing optical observation devices, such as binoculars with integrated laser range finding, require users to note measured data while in the observation position, limiting their ability to move towards a target without obstruction and making navigation cumbersome, especially in challenging environments like mountains.
Innovation Solution
The integration of a modular design with external actuating elements, including a target acquisition module and navigation module, featuring a microcomputer unit, GPS, electronic compass, inclination sensor, and display screen, allows for easy operation and utilization of measured data for navigation, with features like automatic data storage and energy-saving functions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If users wear binoculars with integrated laser range finding for target observation, then precise range finding and target acquisition are enabled, but users cannot move towards the target without obstruction and must note measured data manually
Solution Approach 1:
The patent creates a visual copy of the measurement data by projecting it onto the ocular lens. The measured distance and directional information are displayed as visual overlays that appear superimposed on the target view, allowing users to navigate without manually noting data. This copying of information into the visual field resolves the contradiction by enabling both precise measurement and easy navigation simultaneously.
Solution Approach 2:
The patent introduces an intermediary display system between the laser rangefinder and the user's eye. This intermediary projects measurement data and navigation information into the observation beam path, serving as a mediator that translates raw measurement data into actionable visual guidance. The intermediary system enables users to navigate towards targets without removing the binoculars from their eyes.
2Measurement precision
If binoculars with integrated laser range finding are used for target acquisition, then distance measurement is possible, but measured data cannot be utilized for navigation without manual notes
Solution Approach 1:
The patent copies navigation-relevant information directly into the user's visual field through the ocular lens. Distance measurements, directional data, and navigation instructions are projected as visual overlays that accompany the target view. This eliminates information loss by ensuring navigation data is always available and visible to the user during the navigation process.
Solution Approach 2:
The patent performs preliminary processing of measurement data to extract navigation-relevant information before the user needs it. The system automatically calculates directional vectors, remaining distances, and navigation instructions based on the laser measurements, making this information ready for immediate use during navigation without requiring manual intervention.
3Adaptability or versatility
If external display screens are added to binoculars for navigation, then navigation functionality is improved, but device complexity and production costs increase
Solution Approach 1:
The patent merges the navigation display function with the existing optical observation system by projecting data onto the ocular lens. Instead of adding a separate external display, the system combines navigation information presentation with the target observation function. This merging approach enables navigation functionality while avoiding the complexity and cost of separate display hardware.
Solution Approach 2:
The patent makes the existing ocular lens serve multiple functions: it transmits the target view image and simultaneously projects navigation information and measurement data. This multi-functionality approach allows the same optical component to handle both observation and navigation display, avoiding the need for additional dedicated display components and reducing overall device complexity.
