Pallet Turntable Rotation for Dense Warehouse Picking Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pallet systems make it difficult for pickers to access articles not directly in front of them, leading to strain and inefficiency, as prior solutions that address this issue often compromise storage density and require rack redesigns.
Innovation Solution
A rotating apparatus integrated into or mounted on a pallet, allowing articles to be rotated in 90-degree or 180-degree increments, positioned on top or below the pallet, enabling easier access without compromising storage density.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If additional space is provided about the top and/or sides of the pallet and articles, then picker access is improved, but warehouse storage density is reduced
Solution Approach 1:
The patent applies the dynamics principle by implementing a rotating platform that allows articles to be rotated into position. Instead of providing static additional space around the pallet, the system dynamically rotates the articles themselves, allowing pickers to access articles that were originally positioned at the back or sides of the pallet without requiring extra clearance space.
Solution Approach 2:
The patent applies the another dimension principle by adding rotational movement to the traditionally static pallet configuration. The rotating platform introduces a new degree of freedom (rotation) that allows articles to be repositioned from any location on the pallet to the front position, effectively utilizing the rotational dimension to solve the access problem without requiring additional linear space.
2Ease of operation
If access to articles is provided from additional and/or all sides of the pallet, then picker access is improved, but rack redesign is required
Solution Approach 1:
The patent applies the segmentation principle by separating the rotation function from the rack structure. The rotating platform is a self-contained unit that operates independently within the existing rack framework. This segmentation allows the rotation mechanism to be implemented without modifying the rack design, as the platform fits within the existing pallet position and rotates articles locally rather than requiring rack-level reconfiguration.
Solution Approach 2:
The patent applies the universality principle by designing a rotating platform that can be used with standard pallets and existing rack systems. The platform maintains compatibility with conventional pallet dimensions and rack beam levels, allowing it to function universally across different warehouse configurations without requiring specialized rack redesign.
3Ease of operation
If the entire pallet rotates on a turntable, then article access is improved, but space requirements increase
Solution Approach 1:
The patent applies the segmentation principle by dividing the rotation function into two parts: a stationary base platform and a rotating article carrier. Only the articles and their immediate support structure rotate, while the base remains fixed. This segmentation significantly reduces the rotation radius and space requirements compared to rotating the entire pallet, as only the essential article-holding portion needs to rotate.
Solution Approach 2:
The patent applies the inversion principle by reversing the traditional approach: instead of rotating the pallet underneath the articles (which requires large clearance space), the articles are placed on a rotating platform that rotates above a stationary base. This inversion allows rotation to occur within a compact footprint, as the rotation axis is positioned at the center of the article carrier rather than requiring peripheral clearance.

AI summary
An apparatus and method for rotating articles stored on a pallet without rotating the entire pallet. The turntable of the present invention is located on the pallet or integrated into the top surface of the pallet. By rotating the pallet within the rack, the articles thereon may be loaded and unloaded from a position directly in front of the picker.
