Side-Engaging Lifting Tools for Stable Machine Movement in Narrow Aisles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Machines used in data centers, such as robots for automated server handling, are difficult to move due to narrow aisles and tight corners, and lifting from the bottom surface can be unstable, potentially damaging sensors or components and preventing movement through tight spaces.
Innovation Solution
A lifting tool and caboose tool engage opposing sides of the target object, using brackets and protrusions with specific hole and shaft configurations to lift and move the object, allowing stable maneuverability through narrow spaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a forklift is used to lift the machine from the bottom surface, then the machine can be moved, but the lifting becomes unstable and prevents movement through tight spaces
Solution Approach 1:
The patent transitions from bottom-surface lifting (vertical dimension only) to side-surface lifting (combining horizontal and vertical dimensions). The lifting tool engages with the side surface of the machine, allowing the lifting force to be applied at an angle that provides both vertical elevation and horizontal stability, enabling the machine to be lifted and moved through narrow aisles and tight corners without instability.
2Ease of operation
If the machine bottom surface is accessed for lifting, then lifting can be performed, but the narrow aisle width prevents safe passage
Solution Approach 1:
The patent applies side-surface lifting instead of bottom-surface lifting, changing the dimension in which the lifting force is applied. This allows the machine to be lifted from its side, enabling it to be maneuvered through narrow aisles and tight corners without requiring sufficient clearance at the bottom surface, thus reducing the effective aisle width requirement.
3Ease of operation
If the machine is lifted from the bottom surface, then movement is possible, but sensors or components may be damaged
Solution Approach 1:
The patent introduces a lifting tool as an intermediary device that engages with the side surface of the machine. This intermediary approach allows the machine to be lifted without direct contact between the lifting mechanism and the machine's bottom surface, thereby protecting sensors and components from potential damage while still enabling machine movement.
4Reliability
If a lifting tool with bracket and holes is used, then stable lifting is achieved, but the device complexity increases
Solution Approach 1:
The lifting tool is segmented into distinct functional components: a bracket portion for engagement, a lifting mechanism for elevation, and a caboose tool for auxiliary support. Each component performs a specific function, and the modular design allows for easier manufacturing and maintenance while achieving stable lifting through the coordinated action of these segmented parts.
