Rotatable Cabin Mount with Isolators for Blast and Vibration Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Vehicles face challenges in compactly housing components while maintaining blast resistance and occupant comfort, and in efficiently switching between armored and unarmored configurations, with existing solutions requiring numerous components and significant storage space.
Innovation Solution
The vehicle design incorporates a rotatable front cabin with pivot mounts and isolators to reduce vibration, a movable seat for improved headroom, and a reconfigurable door system that can switch between armored and unarmored configurations by adding or removing components, allowing for enhanced protection without the need for multiple door sets.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the front cabin is rotated away from the engine to facilitate maintenance, then accessibility for maintenance is improved, but the number of components required increases and blast resistance is compromised
Solution Approach 1:
The front cabin is made rotatable relative to the engine assembly, allowing it to dynamically change position between a maintenance position (rotated away for accessibility) and an operational position (aligned for blast resistance). This dynamic reconfiguration eliminates the need for multiple fixed configurations and reduces the number of components required.
2Ease of operation
If the front cabin is rotated away from the engine to facilitate maintenance, then accessibility for maintenance is improved, but blast resistance deteriorates
Solution Approach 1:
The front cabin's ability to rotate allows it to adapt its orientation dynamically - positioned at an angle during maintenance for accessibility, and aligned with the vehicle's longitudinal axis during operation for optimal blast resistance. This dynamic positioning resolves the contradiction between maintenance accessibility and blast resistance.
3Adaptability or versatility
If the floor of the center portion is raised to facilitate gun operation, then gun operation capability is improved, but headroom for seated occupants deteriorates
Solution Approach 1:
The center floor section is made movable between a raised position (when the gun is operational, providing clearance for the gun mechanism) and a lowered position (when the gun is not in use, maximizing headroom for seated occupants). This dynamic adjustment resolves the contradiction between gun operation capability and occupant comfort.
4Adaptability or versatility
If entire replacement doors are used to switch between armored and unarmored configurations, then configuration versatility is improved, but manufacturing cost and storage space requirements increase
Solution Approach 1:
The door assembly is segmented into modular components - an armor layer, a door structure, and connecting elements. These segments can be independently assembled and disassembled, allowing the vehicle to switch between armored and unarmored configurations by attaching or removing only the armor layer rather than replacing entire door assemblies. This reduces manufacturing cost and storage requirements.
5Adaptability or versatility
If entire replacement doors are used to switch between armored and unarmored configurations, then configuration versatility is improved, but storage space requirements increase
Solution Approach 1:
The door system is divided into separate modular components that can be stored independently. The armor panels can be stored in a compact manner separate from the door structures, significantly reducing the storage space required compared to storing complete replacement door assemblies. This segmentation enables configuration versatility while minimizing storage requirements.
