Dual Articulated Support for Bridge-Laying Vehicle Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Bridge-laying vehicles face instability due to shifting center of gravity and unbalanced forces during bridge deployment, as existing support devices only effectively absorb longitudinal forces, leaving transverse forces unaddressed, which can lead to vehicle tipping and instability.
Innovation Solution
The implementation of a support device with two articulated supports arranged transversely to each other, allowing for the absorption of forces from different directions, including longitudinal and transverse forces, with the ability to tilt and distribute forces evenly across multiple supports to enhance stability and prevent tipping.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If only one articulated support is provided for absorbing longitudinal forces, then the structure is simple and space-saving, but transverse forces cannot be absorbed leading to vehicle instability
Solution Approach 1:
The support device is segmented into multiple articulated supports (first articulated support for longitudinal forces, second articulated support for transverse forces) that can independently absorb forces from different directions, resolving the contradiction by dividing the force absorption function across separate components rather than relying on a single multi-directional support
Solution Approach 2:
Each articulated support is designed with specific directional force absorption capabilities, where the first articulated support handles longitudinal forces and the second handles transverse forces, creating a universal system that can handle multiple force directions through specialized components working together
2Reliability
If articulated supports are designed to absorb forces from multiple directions, then vehicle stability improves, but the service life of the articulated supports decreases due to increased stress
Solution Approach 1:
The force absorption function is segmented across multiple articulated supports, each dedicated to a specific force direction. This segmentation allows each support to be optimized for its specific loading condition, reducing stress concentration and extending service life while maintaining overall vehicle stability
Solution Approach 2:
Each articulated support is designed with local quality optimized for its specific force absorption direction - the first articulated support is optimized for longitudinal forces while the second is optimized for transverse forces, allowing each component to operate within its optimal stress range and extend durability
3Reliability
If the support plate is fixed in position, then the structure is simple, but the vehicle cannot be stabilized when the center of gravity shifts during bridge deployment
Solution Approach 1:
The support plate is designed with dynamic positioning capability through articulated connections that allow it to adapt its position and orientation in response to shifting center of gravity during bridge deployment, enabling the system to maintain stability under varying operational conditions
Solution Approach 2:
The articulated support mechanism provides passive feedback through its mechanical structure, automatically adjusting the support plate position in response to force imbalances caused by center of gravity shifts, eliminating the need for active control systems while maintaining vehicle stability

AI summary
The invention relates to a support device (1) for arrangement on a vehicle, in particular a bridge laying vehicle, with a support shield (4) that can be moved back and forth between a support position and a driving position via a lifting device (3) and a hinged support (5) for supporting the support shield (4) in a first support direction (R1), wherein a second hinged support (6) is provided for supporting the support shield (4), the support direction (R2) of which differs from the support direction (R1) of the first hinged support (5).
