Solution Overview
Problem
Existing weapon sights lack the ability to selectively display and overlay aiming graphics and changing information based on data collected by sensors associated with the weapon or its environment.
Innovation Solution
A weapon display device comprising a display engine, a waveguide, and a chassis, which is configured to mount to a weapon or an optic, allowing for the selective output of light and graphics that can be aligned with the optical axis of the optic, thereby providing enhanced situational awareness and aiming capabilities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a weapon sight displays aiming graphics and information, then situational awareness is improved, but the device complexity increases
Solution Approach 1:
The patent employs a waveguide as an intermediary optical element that transmits and directs light from the display engine to the user's eye while maintaining alignment with the optic's optical axis. This intermediary component enables the integration of display functionality into the existing optic structure without requiring a complete system redesign, thus improving situational awareness while managing device complexity through modular integration.
Solution Approach 2:
The display device is designed to be universally mountable on various optics through a standardized chassis that interfaces with the optic's mounting system. The same device can display aiming graphics, sensor data, and other information overlays across different weapon systems, making it a multi-functional solution that improves situational awareness without requiring system-specific custom designs for each application.
2Measurement precision
If the display device is mounted on the optic, then alignment precision is improved, but the ease of operation decreases
Solution Approach 1:
The display device is segmented into distinct functional modules: a chassis for mounting, a display engine for generating graphics, and a waveguide for optical transmission. This segmentation allows the mounting function to be separated from the display functions, enabling precise alignment through the chassis while maintaining ease of operation through independent adjustment of display parameters without affecting the mechanical mounting configuration.
Solution Approach 2:
The chassis is designed with adjustable mounting mechanisms that allow dynamic alignment adjustment after installation. This enables the device to be precisely aligned with the optic's optical axis during setup, and then maintained in that precise alignment during operation, resolving the contradiction between achieving high alignment precision and maintaining ease of operation during use.
