Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current trailer loading systems are impractical and require extensive space and operator intervention due to complex procedures and limited applicability to trailers with multiple axles, making them inefficient for loading large vehicles without disconnecting from the tractor.
Innovation Solution
A trailer equipped with a tilting axle unit utilizing pneumatic or hydraulic actuators, telescopic supports, and rotating fifth-wheel couplings allows for automatic repositioning of rear axles, enabling easier and quicker loading without extensive space or operator intervention, using readily available mechanical parts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the traditional loading procedure is used (detaching trailer, lowering front, removing coupling device), then the loading deck can be accessed for loading vehicles, but the procedure becomes complex, time-consuming, and requires large amounts of space and operator intervention
Solution Approach 1:
The invention extracts the rear axles from their fixed position at the rear end of the trailer and relocates them to a lateral position using a tilting mechanism. This extraction of the obstructing element (rear axles) from the loading path enables the loading deck to be accessed without detaching the trailer or removing coupling devices, thereby simplifying the loading procedure while maintaining trailer-tractor connection.
Solution Approach 2:
The invention introduces dynamic capability to the previously static rear axle system by implementing a tilting mechanism that allows the rear axles to rotate around a longitudinal axis. This dynamic repositioning enables the rear axles to move from a vertical load-bearing position to a lateral position clear of the loading deck, facilitating easy access during loading operations without requiring trailer detachment.
2Ease of operation
If the rear axles are moved to a lateral position using manual dismantling and reassembly, then the loading deck becomes accessible, but the procedure requires significant operator intervention and is time-consuming
Solution Approach 1:
The invention implements self-service capability through an automated tilting mechanism that repositions the rear axles laterally using pneumatic or hydraulic actuators. The system automatically performs the axle repositioning operation without requiring manual dismantling, reassembly, or significant operator intervention. The mechanism includes self-contained components such as actuators, telescopic supports, and locking devices that operate autonomously to achieve axle relocation and secure positioning.
Solution Approach 2:
The invention employs pneumatic or hydraulic actuators to power the tilting mechanism that repositions the rear axles. These fluid power systems provide automated, high-force actuation to rotate the rear axles around the longitudinal axis and move them to the lateral position. The use of pneumatic/hydraulic systems enables rapid, operator-minimal repositioning operations compared to manual methods, significantly reducing preparation and execution time.
3Adaptability or versatility
If the tilting mechanism is implemented on trailers with multiple rear axles, then loading of large vehicles is enabled, but the mechanism becomes more complex to dismantle and reassemble
Solution Approach 1:
The invention divides the tilting mechanism into independent, modular units, with each rear axle equipped with its own tilting mechanism comprising an actuator, telescopic support, and locking device. This segmentation allows each axle to be tilted and positioned independently, enabling the system to accommodate trailers with any number of rear axles. The modular design simplifies manufacturing and assembly, as each unit can be produced separately and installed independently, rather than requiring a complex integrated system for multiple axles.
Solution Approach 2:
The invention creates a universal tilting mechanism design that can be applied to trailers with one or more rear axles. The standardized tilting unit with actuator, telescopic support, and locking device serves the same function regardless of the number of axles, making the system adaptable to various trailer configurations. This multi-functional design enables the same mechanism to be replicated across multiple axles without increasing overall system complexity, as each unit operates independently with identical components.
