Movable Sight Frame Assembly for Weapon Simulator
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The bulk of virtual reality (VR) head-mounted displays (HMDs) prevents military trainees from properly aligning the sight frame assembly on MANPADS weapon simulators, making it difficult to achieve a realistic training experience.
Innovation Solution
A sight frame assembly with a sliding pin and spring mechanism that allows for adjustable clearance to accommodate VR HMDs, enabling trainees to properly position their heads and interact with the physical sight frame assembly during virtual training.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a VR head mounted display is used for training, then the training can be conducted in a virtual environment, but the bulk of the HMD prevents the trainee from placing their head in the proper position next to the training device
Solution Approach 1:
The sight frame assembly is made movable along the longitudinal axis through a sliding mechanism with connection arms and guide rods, allowing the assembly to dynamically adjust its position to accommodate the VR HMD bulk while maintaining proper alignment for training
Solution Approach 2:
A spring mechanism serves as an intermediary between the sight frame assembly and the weapon simulator body, providing controlled movement and positioning assistance to enable proper head placement despite the HMD bulk
2Ease of operation
If the sight frame assembly is made movable to accommodate HMD bulk, then proper head positioning is enabled, but the structural complexity of the assembly increases
Solution Approach 1:
The sight frame assembly is divided into separable components including connection arms, guide rods, and a movable frame section, allowing controlled movement while maintaining structural integrity and reducing overall complexity
Solution Approach 2:
The position of the sight frame assembly along the longitudinal axis is made variable through the sliding mechanism, allowing adjustment of the parameter (position) to accommodate different training scenarios and HMD sizes
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution provides a realistic training environment by allowing trainees to maintain proper head positioning and interact physically with the sight frame assembly, enhancing the realism and effectiveness of virtual reality training scenarios.
Implementation Method 1
a spring concentrically positioned around the second guide rod or the first guide rod; wherein the sight frame assembly is disposed in a first position along a longitudinal axis of the weapon simulator when the spring is in an uncompressed state; and wherein the sight frame assembly is disposed in a second position along the longitudinal axis of the weapon simulator when the spring is in a compressed state

AI summary
A sight frame assembly for a weapon simulator includes one or more connection arms. The connection arms are for slidably coupling the sight frame assembly to the weapon simulator. The connection arms include a passageway for slidably receiving a guide rod that is attached to a sight frame assembly mounting point on the weapon simulator. A spring is positioned in proximity to the guide rod. The sight frame assembly is disposed in a first position along a longitudinal axis of the weapon simulator when the spring is in an uncompressed state, and the sight frame assembly is disposed in a second position along the longitudinal axis of the weapon simulator when the spring is in a compressed state.
