Auto Zoom Aiming Device Dynamic Magnification Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current aiming devices require users to manually adjust between low magnification for wide field of view and high magnification for accuracy, often resulting in guesswork, insufficient time for adjustment, or an unwieldy process for target acquisition.
Innovation Solution
An electronically controlled aiming system that uses a video camera module and image processor to dynamically adjust the field of view, providing a large field of view when the aiming device is in motion and progressively narrowing it when stationary, allowing for rapid transition between magnification settings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the aiming device is set to high magnification to improve target accuracy, then the field of view becomes narrow making target acquisition difficult, but if set to low magnification for wide field of view, then target accuracy deteriorates
Solution Approach 1:
The patent applies dynamics by making the magnification setting changeable during operation. The system automatically transitions between low magnification (for wide field of view during target acquisition) and high magnification (for accuracy during firing), eliminating the need for manual compromise settings and allowing optimal performance at each stage of the aiming process
Solution Approach 2:
The patent changes the magnification parameter dynamically based on the operational phase. The system detects when the aiming device is stationary (indicating target acquisition) and automatically switches to high magnification, then switches back to low magnification when motion is detected, thus optimizing both field of view and target accuracy at different times
2Measurement precision
If the user manually adjusts magnification from low to high to acquire and then fire at a target, then both wide view and accuracy can be achieved, but the process takes insufficient time for rapid engagement
Solution Approach 1:
The system performs self-service by automatically detecting when the aiming device becomes stationary and autonomously switching to high magnification without requiring manual intervention. This eliminates the time loss associated with manual adjustment while maintaining both wide field of view capability and target accuracy
Solution Approach 2:
The system uses feedback from motion detection to control magnification changes. By monitoring whether the aiming device is moving or stationary, the system automatically adjusts magnification accordingly, enabling rapid transition between acquisition and firing phases without manual input
3Measurement precision
If the user attempts to acquire a target at high magnification, then target accuracy can be maximized, but the process becomes unwieldy and time-consuming
Solution Approach 1:
The system dynamically adjusts magnification based on operational needs, starting with low magnification for easy target acquisition with wide field of view, then automatically transitioning to high magnification when the target is acquired and the device is stationary, thus maximizing ease of operation during acquisition and accuracy during firing
Solution Approach 2:
The system performs preliminary action by first establishing a wide field of view at low magnification to facilitate easy target acquisition, then automatically transitions to high magnification when ready, eliminating the need to attempt difficult high-magnification acquisition from the start
