Foldable Stanchion Device for Timber Transport
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing stanchion devices for transport vehicles are inadequate for securely transporting both round and sawn timber, as they either damage sawn timber with jagged surfaces or fail to securely hold round timber during transport.
Innovation Solution
A stanchion device with a head-side profile that forms an uppermost surface when transporting logs and converts to a flat surface for sawn timber, allowing for secure fastening of both types without damage, featuring foldable stanchions and a central element with projecting and recessed areas that can be integrated into the stanchion bolster.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a profiled surface with spikes or projecting areas is provided on the stanchion bolster, then round timber is securely fastened against slipping, but sawn timber surface is damaged
Solution Approach 1:
The stanchion device employs foldable stanchions that can be positioned in different configurations. When transporting round timber, the stanchions are extended to engage with the profiled surface for secure fastening. When transporting sawn timber, the stanchions are repositioned to provide a flat support surface, eliminating damage to the timber surface while maintaining securing capability.
2Object-affected harmful factors
If a flat surface is provided for sawn timber transport, then sawn timber is not damaged, but round timber cannot be securely fastened
Solution Approach 1:
The device transforms from a static structure to a dynamic one where stanchions can be folded and repositioned. This allows the same stanchion device to provide different surface characteristics (profiled for round timber, flat for sawn timber) depending on the transport requirements, resolving the contradiction between securing round timber and protecting sawn timber.
Solution Approach 2:
The stanchion device is designed to perform multiple functions by accommodating different timber types. The foldable stanchions combined with the profiled surface create a universal device that can securely fasten round timber when stanchions are extended, and safely support sawn timber when stanchions are repositioned, eliminating the need for separate devices for different timber types.
3Device complexity
If fixed stanchions are used, then the structure is simple, but the device cannot adapt to different timber types and dimensions
Solution Approach 1:
The stanchion device transitions from fixed to foldable stanchions that can be repositioned between extended and retracted positions. This dynamic capability allows the device to adapt to different timber types (round and sawn), dimensions, and packing configurations while maintaining a relatively simple overall structure that does not require multiple separate devices.

AI summary
The post device (1) has post units (3,4) that are connected via post bolster (2). A surface of each post unit is coated with an elastic material. A head-side section (6) of an element (5) is provided with protruding and recessed portions, and the head-side section is co-defined with surfaces (7,8) of post bolster during operating state of the device.
