Scissor Lift Pallet Lifter With Adjustable Display Height
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current pallet risers are bulky and require large lifters to load pallets, making them unsuitable for retail environments, and they cannot controllably lift or lower pallets to an optimal height for displaying bulk goods effectively.
Innovation Solution
A compact pallet lifter with a manually or mechanically adjustable top support surface that can be easily loaded by hand, featuring a lifting frame and movement mechanism allowing controlled height adjustment, including a motorized option and height sensor for maintaining optimal product display.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If coiled spring pallet lifters are used to raise pallets to display height, then the pallet can be elevated for better product visibility, but the device becomes bulky and requires large trucks or hydraulic lifters for loading
Solution Approach 1:
The pallet lifter uses adjustable legs that can extend and retract to dynamically change the device height. When legs are extended, the platform reaches display height (20-40 inches) for visibility; when retracted, the device becomes compact for easy loading with hand-pulled movers instead of requiring bulky fixed-height structures
Solution Approach 2:
The lifting mechanism is divided into separate adjustable legs that can be independently controlled. This segmentation allows the platform to be raised to optimal display height while keeping the base compact, resolving the contradiction between visibility height and device compactness
2Loss of information
If fixed-height display frames are used to encircle pallets, then product information can be displayed, but the top layer of goods becomes hidden when bags are removed
Solution Approach 1:
The platform height is dynamically adjustable rather than fixed. As goods are removed from the pallet and its height decreases, the platform can be raised to maintain the top layer of goods at the optimal viewing level, preventing the goods from being hidden behind the display frame while still allowing product information to be displayed
3Ease of operation
If hand-pulled pallet movers are used in retail environments, then large trucks are avoided, but the pallet cannot be lifted high enough for loading onto standard pallet lifters
Solution Approach 1:
The platform is preliminarily positioned at a low loading height that is accessible to hand-pulled pallet movers. Once the pallet is loaded onto the platform, the legs are then extended to raise the pallet to the final display height, separating the loading phase from the display phase and enabling the use of simple hand-pulled movers

AI summary
A pallet lifter for raising and lowering a pallet. The pallet lifter includes a pallet platform, a lifting frame that supports the pallet platform, and a movement mechanism that controllably causes the pallet platform to raise and lower. The pallet platform includes a top surface designed to support a pallet, two side walls and a back wall. The lifting frame includes two sets of legs. One end of one or both of the two legs of each set of legs is moveable along a longitudinal axis of the pallet platform as the pallet platform is raised and lowered. The movement mechanism includes a motor and a threaded rod. The electric motor is designed to cause the threaded rod to rotate in a clockwise and counterclockwise direction to cause said pallet platform to raise and lower.
