Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing heads-up displays (HUDs) integrated with small arms aiming systems compromise the user's field of view, reducing combat effectiveness by interfering with sensory perception and awareness, and are susceptible to interference from accelerations and metallic objects.
Innovation Solution
An optical positioning aiming system using infrared emitters and cameras mounted on both the weapon and head-mounted display to determine relative positions, allowing for accurate holographic image projection within the user's field of view without obstructing it, and incorporating sensors for ballistic calculations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a head mounted display is integrated into a head protective system to provide aiming information, then combat effectiveness is improved through better situational awareness, but the field of view of the user is compromised and sensory perception is reduced
Solution Approach 1:
The patent replaces traditional mechanical/optical HUD systems that physically obstruct the user's view with a video overlay system that presents aiming information through a display device worn by the user. The video overlay subsystem captures images through the weapon's optical system and superimposes aiming data on the video feed, allowing information delivery without physical obstruction of the user's natural field of view.
2Measurement precision
If gyroscopic data is used for aiming system positioning, then aiming accuracy is improved, but the system becomes susceptible to interference from accelerations and metallic objects
Solution Approach 1:
The patent introduces an optical positioning subsystem that uses infrared emitters and cameras as intermediary components to establish a direct optical reference between the head mounted display and the weapon. This optical reference system serves as a mediator that provides positioning data independent of gyroscopic sensors, thereby eliminating susceptibility to acceleration and magnetic interference while maintaining aiming accuracy.
