Rack-Shipment System With Rotating Ramp
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for shipping IT equipment racks pre-installed with IT equipment face challenges in efficiently transitioning the racks from a horizontal shipping position to an upright position for removal, particularly due to the weight and mechanical stress involved.
Innovation Solution
A rack-shipment system comprising a pallet, a hingedly coupled rotating ramp, a rack secured to the ramp, and an extendable handle allows the rack and ramp to be rotated upright relative to the pallet, with foam panels providing protection during shipping.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the rack is shipped horizontally on a pallet, then the rack can be securely transported, but the rack cannot be easily removed and positioned upright by a single person
Solution Approach 1:
A ramp is introduced as an intermediary component between the pallet and the rack. The ramp is hingedly coupled to the pallet and can rotate from a stowed position to an extended position, creating an inclined plane that allows the rack to be rolled or slid upright. This intermediary mechanism converts the difficult vertical lift into a manageable rolling motion along the incline, enabling single-person operation despite the rack's weight.
Solution Approach 2:
The ramp is designed with rotational capability, transitioning from a static stowed position during shipping to a dynamic extended position during unpacking. The ramp rotates about a hinge axis to change its orientation, creating a movable inclined plane that adapts to the unpacking operation. This dynamic transformation allows the same structure to serve dual purposes: secure horizontal shipping and facilitated upright positioning.
2Ease of operation
If the ramp is extended to help position the rack upright, then the rack can be easily removed, but the device complexity increases
Solution Approach 1:
The ramp and pallet are combined into a single integrated assembly through hinged coupling. The ramp is attached to the pallet in such a way that it can rotate relative to the pallet but remains structurally connected. This merging eliminates the need for separate ramp and pallet components that would require independent handling, reducing overall system complexity while maintaining the extended position functionality for easy rack removal.
Solution Approach 2:
The ramp serves multiple functions: (1) it acts as a structural support during horizontal shipping when in the stowed position, and (2) it becomes an inclined plane for facilitating rack removal and upright positioning when extended. This multi-functionality reduces the need for additional specialized components, thereby minimizing device complexity while achieving ease of operation.
3Reliability
If foam panels are added to protect the rack during shipping, then the rack is protected from damage, but the device complexity increases
Solution Approach 1:
Foam panels are installed on the rack before shipping, positioned to cushion and protect critical surfaces. These panels are strategically placed at locations most susceptible to damage during horizontal transport and upright positioning. The beforehand cushioning approach ensures protection is already in place before any potential impact occurs, enhancing reliability without requiring complex active protection systems.
Solution Approach 2:
The foam panels are made from the same or similar material as the existing rack structure, or at least compatible in terms of mechanical properties and aesthetic appearance. This homogeneity ensures that the protective panels integrate seamlessly with the rack design, minimizing visual and structural discontinuities. The uniform material selection simplifies the overall device complexity by avoiding the introduction of disparate, complex protective systems.

AI summary
A rack-shipment system includes a pallet, a ramp hingedly coupled to the pallet, a rack coupled to the ramp, and a handle coupled to the rack. The ramp, the rack, and the handle are configured to rotate relative to the pallet to an upright position. The rack-shipment system further may include a cover operably coupled to the pallet and the ramp to enclose the rack, a top foam panel disposed on a side of the rack, and a bottom foam panel disposed on an opposite side of the rack. A method of shipping a rack includes positioning the rack on the pallet; coupling the ramp to the rack, and enclosing the rack for shipment.
