Switchable Reticle Sight for Variable Magnification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current aiming devices, such as FFP and SFP sights, either have reticles that become too small at low magnifications or remain constant in size, making them less effective for various usage scenarios, as they cannot seamlessly switch between the two forms to accommodate different magnification needs.
Innovation Solution
A sight capable of switching reticles, comprising an objective lens, image acquisition device, display device, controller, and eyepiece, which allows users to switch between FFP and SFP modes by adjusting reticle size and magnification based on user instructions, enabling flexible reticle display.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If FFP sight is used, then reticle function can be used at all magnifications, but reticle becomes very small at low magnifications and hard to see clearly
Solution Approach 1:
The patent implements dynamic reticle switching between FFP and SFP modes based on magnification level. The system automatically detects the current magnification and switches reticle display accordingly, making the reticle large and visible at low magnifications while maintaining functionality at high magnifications.
Solution Approach 2:
The sight device integrates both FFP and SFP reticle modes in a single system, allowing it to perform the functions of both sight types. The controller enables switching between reticle forms based on user needs or magnification level, making the device universally applicable across different shooting scenarios.
2Ease of operation
If SFP sight is used, then reticle size remains moderate and clearly observable at any magnification, but reticle does not change with zoom
Solution Approach 1:
The system dynamically switches between fixed-size SFP reticle and magnification-adjusted FFP reticle based on the current zoom level. At low magnifications, it displays the large SFP reticle for clear visibility, while at high magnifications it transitions to the proportionally scaling FFP reticle to maintain functionality.
Solution Approach 2:
The controller changes the reticle display parameters (size, magnification relationship) based on the optical zoom state. When zooming in, the system adjusts the reticle parameters to maintain appropriate size and functionality, transitioning between different reticle types as needed.
3Ease of operation
If fixed reticle size is used, then reticle is clearly observable, but reticle cannot adapt to different magnification needs
Solution Approach 1:
The reticle display is made dynamic by switching between fixed-size SFP mode and variable-size FFP mode based on magnification. The controller monitors the zoom level and automatically adjusts reticle characteristics to maintain optimal visibility and functionality across the entire magnification range.
