Vehicle Stanchion Lifting Mechanism for Sealing Integrity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing locking arrangements for vehicle bodies, which utilize a strut to reduce dust and moisture ingress, suffer from deformation under load, leading to gaps and cracks that allow additional dust and moisture into the cargo space.
Innovation Solution
A lifting mechanism is introduced, comprising at least one lifting element on the stanchion holder and another at the lower end of the stanchion, which raises the stanchion when it pivots, relieving the strut of vertical pressure and preventing deformation, thus maintaining a seal against the vehicle's side wall.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If the strut is designed as a large-area but relatively thin-walled metal sheet to reduce dust and moisture ingress, then the sealing performance is improved, but the strut deforms under vertical compressive forces
Solution Approach 1:
The support function is segmented between two independent components: the strut (for lateral support and sealing) and the lifting mechanism (for vertical support). This segmentation allows the strut to be optimized for sealing without bearing vertical loads, while the lifting mechanism handles vertical compression separately.
Solution Approach 2:
The lifting mechanism acts as an intermediary that removes vertical compressive forces from the strut before the stanchion is fully closed. By lifting the stanchion during the closing process, the mechanism prevents load transfer to the strut, allowing the thin-walled strut to maintain its sealing function without deformation.
2Force
If the strut bears the weight of the vehicle body when the stanchion is closed, then the structural support is improved, but the strut deforms and creates gaps that allow dust and moisture ingress
Solution Approach 1:
The lifting mechanism performs a preliminary action by lifting the stanchion during the closing process, relieving the strut of vertical loads before the stanchion is fully closed and locked. This preliminary relief prevents deformation and ensures the strut maintains its sealing function throughout the closed state.
Solution Approach 2:
The system transitions from a static load-bearing configuration to a dynamic one where the lifting mechanism actively manages load distribution. The lifting elements (ramps) convert horizontal closing motion into vertical lifting motion, dynamically relieving the strut during the closing process rather than requiring the strut to statically bear vertical loads.
3Object-affected harmful factors
If a lifting mechanism is introduced to relieve the strut, then the sealing performance is improved, but the device complexity increases
Solution Approach 1:
The lifting mechanism is merged with the existing stanchion holder structure. The lifting elements (ramps) are formed as integral parts of the holder, combining the sealing function with the existing support structure rather than adding completely separate components.
Solution Approach 2:
The lifting mechanism is self-actuating through the closing motion itself. As the stanchion is closed horizontally, the ramps automatically convert this motion into vertical lifting, relieving the strut without requiring external actuators, motors, or complex control systems. The closing action serves dual purposes: positioning and load relief.
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
This solution ensures the strut remains free of deformation when the stanchion is closed, preventing load-dependent gaps and cracks, thereby effectively sealing out dust and moisture from the vehicle's loading space.
Implementation Method 1
at least one of the lifting elements is a ramp that rises towards the inside of the vehicle

AI summary
The closing arrangement has a lifting mechanism provided with a lifting element of a stake holder (24). Another lifting element is provided with the former lifting element at the lower end (30) of the stake (2). The stakes are retained in the area of the roof frame and swiveled out towards a vehicle exterior.
