Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual handling of pallets is used, then labor flexibility is maintained, but handling efficiency is low and labor costs are high
Solution Approach 1:
The pallet lifting rack enables self-service operation by integrating the lifting function directly into the rack structure. The rack automatically lifts pallets to different heights using the lifting device, eliminating the need for manual intervention in the lifting process while maintaining operational simplicity
Solution Approach 2:
The pallet lifting rack combines multiple functions into a single device: it serves as both a storage rack and a lifting mechanism. The lifting device integrated into the rack can move pallets between different height levels, making the system adaptable to various handling scenarios without requiring separate lifting equipment
2Productivity
If automated guided vehicle is used for transport, then transport efficiency is improved, but pallet unloading and transfer efficiency remains low due to manual handling
Solution Approach 1:
The patent merges the pallet lifting function with the storage rack structure. The lifting device is integrated into the rack, allowing seamless transfer of pallets from the automatic guided vehicle to the rack without requiring separate handling equipment or complex manual operations
Solution Approach 2:
The lifting device acts as an intermediary between the automatic guided vehicle and the storage rack. It facilitates the transfer process by automatically lifting pallets to the appropriate height, bridging the gap between transport and storage operations
3Adaptability or versatility
If multiple equipment are used for pallet handling, then handling capability is improved, but system complexity and space requirements increase
Solution Approach 1:
The pallet lifting rack is designed as a multi-functional system that combines storage and lifting capabilities in one structure. The lifting device can move pallets between different height levels, making the rack adaptable to various handling requirements without requiring additional specialized equipment
Solution Approach 2:
The patent combines the lifting mechanism with the rack structure itself, eliminating the need for separate lifting equipment. This integration reduces system complexity while maintaining the ability to handle pallets at different heights
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 pallet lifting rack enhances handling efficiency and reduces labor costs by enabling automated pallet movement to different heights, facilitating seamless integration with automatic guided vehicles and storage systems.
Implementation Method 1
a movable bracket mounted on the frame and movable in a vertical direction relative to the frame, a support member connected to the movable bracket, and a driving device driving the movable bracket and the support member to move along the vertical direction

AI summary
A pallet lifting rack includes a pair of lifting devices. Each of the lifting devices has a frame, a movable bracket mounted on the frame and movable in a vertical direction relative to the frame, a support member connected to the movable bracket, and a driving device driving the movable bracket and the support member to move along the vertical direction. The support members of the pair of lifting devices support a bottom surface of a pallet from a pair of sides of the pallet, so that the pallet is supported on the support members and movable to different height positions in the vertical direction by the support members.
