Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for placing pipe segments along pipeline locations are labor-intensive and inefficient, relying heavily on manual labor and human intervention.
Innovation Solution
A self-unloading pipe trailer (SUP trailer) that automatically unloads pipe segments as it moves along the pipeline location, utilizing a power pipe rolling assembly to translate vehicle movement into pipe unloading, allowing operators to control the process from within the vehicle with minimal external systems.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual labor methods are used to place pipe segments, then flexibility and adaptability are maintained, but productivity is low and labor intensity is high
Solution Approach 1:
The pipe trailer serves itself by using its own motion to power the unloading mechanism. The weight-bearing wheels drive the pipe-rolling wheels through friction engagement, eliminating the need for external power sources or complex control systems. The system automatically unloads pipes as the trailer moves forward, with the pipe segments being fed off the trailer by the rolling action of the driven wheels.
Solution Approach 2:
The invention merges the transportation function and the unloading function into a single integrated system. The same wheels that bear the weight of the trailer and pipes also serve as the driving mechanism for unloading the pipes. This combination eliminates the need for separate power transmission systems and reduces overall system complexity.
2Extent of automation
If complex externally powered unloading systems are used, then automation is achieved, but device complexity increases and reliability decreases
Solution Approach 1:
The pipe trailer serves itself by using its own motion to power the unloading mechanism. The weight-bearing wheels drive the pipe-rolling wheels through friction engagement, eliminating the need for external power sources or complex control systems. The system automatically unloads pipes as the trailer moves forward, with the pipe segments being fed off the trailer by the rolling action of the driven wheels.
Solution Approach 2:
The invention extracts and eliminates the complex power transmission components, control systems, and external power sources that would normally be required for automated unloading. By using direct friction-driven engagement between the weight-bearing wheels and pipe-rolling wheels, the system achieves automation without the intermediary mechanisms that would increase complexity and reduce reliability.
3Productivity
If traditional manual pipe placement methods are used, then system simplicity is maintained, but loss of time increases and productivity decreases
Solution Approach 1:
The unloading process continues continuously as the trailer moves along the pipeline location. The friction-driven pipe-rolling wheels constantly feed pipes off the trailer during forward motion, eliminating idle time between pipe placements. The operator simply drives the trailer along the route, and the unloading action occurs continuously without stopping or manual intervention.
Solution Approach 2:
The pipe segments are pre-positioned on the trailer in stacks, ready for unloading. The friction-driven mechanism is pre-configured to engage with the pipes and feed them off the trailer as motion occurs. This preliminary arrangement eliminates the need for manual pipe handling during the unloading process, as the system is already prepared to automatically discharge pipes in sequence.
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
The SUP trailer significantly reduces human intervention and increases efficiency in pipeline construction by automatically unloading pipe segments, maintaining synchronization with vehicle velocity and eliminating the need for complex external unloading systems.
Implementation Method 1
The power pipe rolling wheel assembly (300) is friction-driven by the weight-bearing wheel assembly (200) when the power pipe rolling wheel assembly (300) is engaged against the weight-bearing wheel assembly (200).

AI summary
A self-unloading pipe trailer carries a rack of pipe and automatically unloads segments as it moves along a pipeline location. A single operator can maneuver the trailer and operate the unload controls. In unload mode, the operator drives along the pipeline and the trailer unloads the segments automatically. The trailer employs a power pipe rolling assembly that engages with weight-bearing tires in order to translate the distance traveled across the ground to directly power a pipe unloading system such that each foot of ground travel equates to a foot of pipe unloading. If the operator needs to change speed and/or stop, it can be done without modifying the unload mode as the dispensing process automatically responds to the change in speed. There is no complex externally powered unloading system to break-down, lose timing, or otherwise complicate matters. Pipe is simply unloaded automatically as the trailer moves down the pipeline.
