Weapons Port Single-Penetration Assembly for Easier Installation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional gun ports with non-circular frames require complex drilling and multiple uniform holes, making installation challenging and costly, and necessitate replacement if damaged.
Innovation Solution
A weapons port design utilizing a single penetration adjacent to the opening, featuring a door plate, handle, and hardware that simplifies installation by eliminating the need for non-circular bores and multiple uniform holes, using a carriage bolt with washers and nuts for secure linkage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a non-circular frame is used to define the weapons port mouth, then the structural integrity and fit of the frame is improved, but the manufacturing complexity and difficulty of drilling/cutting the bore increases significantly
Solution Approach 1:
The weapons port assembly is divided into separate components: a circular frame that is easy to manufacture and install, and a non-circular door plate that provides the required structural integrity and fit. The circular frame serves as a simple mounting structure, while the door plate contains the non-circular shape that defines the actual weapons port opening.
2Reliability
If multiple holes are drilled to secure the frame, then the frame can be properly fastened in place, but the installation time and precision requirements increase
Solution Approach 1:
The fastening function is extracted from the frame itself and transferred to the door plate. Instead of drilling multiple holes through the frame to secure it, the door plate is designed with features that allow it to be securely fastened with minimal holes, while the circular frame remains a simple unbroken structure that is easier and faster to install.
3Reliability
If multiple holes at uniform depths and accurate spacing are required, then the frame can be properly secured, but the manufacturing precision and cost increase
Solution Approach 1:
The functions of frame mounting and door securing are segmented into separate components. The circular frame requires no precision holes for mounting, while the door plate incorporates the necessary fastening features with minimal precision requirements, thereby reducing overall manufacturing complexity and cost.

AI summary
A blast shield or similar assembly/apparatus includes a panel and a weapons port coupled with the panel. The weapons port includes a door plate constructed and arranged to control access to a weapons port opening in a panel. The weapons port further includes a handle, and hardware constructed and arranged to couple the door plate with the handle and extend through a single penetration in the panel. The single penetration is adjacent to and separate from the weapons port opening in the panel. In some arrangements, the panel is constructed and arranged to extend outwardly from a vehicle. In some arrangements, the panel forms part of a body of a vehicle. Other arrangements are suitable as well such as the panel forming at least a portion of a wall structure, stationary partition, or similar fortified barrier, and so on.
