Firearm Positioning Structure Using Roll-Bar Constraint
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing armored vehicles without integrated firearm positioning systems face difficulties in stabilizing and controlling the main armament, particularly when the vehicle is not manufactured with such positioning means, leading to challenging firearm positioning and control.
Innovation Solution
A fixed positioning structure for the firearm is directly connected to the vehicle's frame, specifically to the reinforcement bars (roll-bars), using a box-shaped plate with constraint portions and a fastening mechanism, which includes sleeves, brackets, and a circumferential fifth wheel, to securely mount the machinegun and house the electronic control unit, maintaining the vehicle's mechanical integrity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a firearm is mounted on a vehicle without integrated positioning means, then the vehicle structure remains unaltered, but the positioning and control of the firearm become difficult
Solution Approach 1:
The positioning structure is divided into separate modular components including a mounting plate, constraint portions for roll-bars, and a fifth wheel mechanism. This segmentation allows the firearm positioning system to be installed independently without altering the vehicle's original structure, while providing stable positioning through the distributed constraint points.
Solution Approach 2:
The positioning structure acts as an intermediary device between the vehicle frame and the firearm. It includes constraint portions that attach to existing roll-bars and a fifth wheel mechanism that provides the actual positioning interface for the firearm, thereby enabling stable positioning and control without direct modification to the vehicle structure.
2Stability of the object's composition
If the vehicle frame is directly modified to add positioning means, then the firearm positioning becomes stable, but the vehicle's mechanical integrity and original structure are altered
Solution Approach 1:
The positioning structure utilizes the vehicle's existing roll-bars as predetermined attachment points. By designing constraint portions that interface with these pre-existing structural elements, the system achieves stable firearm positioning without requiring modifications to the vehicle's primary load-bearing structure, thereby preserving mechanical integrity.
Solution Approach 2:
The positioning structure serves as an intermediary that transfers loads between the firearm and the vehicle's existing roll-bars. This mediator approach distributes forces through the constraint portions without concentrating stress on critical vehicle structural elements, maintaining the vehicle's original mechanical integrity while providing stable firearm mounting.
3Measurement precision
If a complex positioning system is installed on the vehicle roof, then the firearm control precision improves, but the vehicle's physiognomy and mechanical characteristics are substantially altered
Solution Approach 1:
The positioning structure concentrates its functional elements in localized areas on the vehicle roof. The mounting plate and constraint portions occupy minimal space and can be positioned in discrete locations, thereby providing precise firearm positioning control without substantially altering the overall vehicle physiognomy or aerodynamic characteristics.
Solution Approach 2:
The positioning system is segmented into discrete components that can be independently positioned and configured. This includes separate constraint portions for different roll-bars and a modular fifth wheel mechanism, allowing the system to achieve positioning precision while maintaining a compact footprint that minimizes impact on the vehicle's external appearance and aerodynamics.

AI summary
Positioning structure for an armament on a vehicle equipped with an armored cockpit (A) and wherein the armament is constrained to the top of the vehicle. The positioning structure engages directly to the frame of the vehicle and in particular to the reinforcement bars (B) typically called roll-bars, which delimit the armored cockpit.
