Levered Load Carrier for Lifting Heat Pumps Off Pallets
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing load handling devices struggle with efficiently lifting loads from transport pallets and transporting them to final installation locations, particularly for heavy items like thermal devices such as heat pumps, without causing damage or requiring complex mechanisms.
Innovation Solution
A load conveying device with rotatably connected main support elements and wheels that function as a lever, allowing the wheels to be pivoted underneath the load to lift it off the pallet, using a pivot axis parallel to the load's center of gravity, and incorporating crossbeams for secure attachment and transport.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional load handling devices are used, then the load can be transported, but the lifting process from transport pallet is complex and difficult
Solution Approach 1:
The load handling device is segmented into separate functional components: main support elements for lifting, crossbeams for structural support, and wheels for transport. This segmentation allows each component to perform its specific function efficiently, with the main support elements rotating independently to provide leverage for lifting without requiring a complex integrated mechanism.
Solution Approach 2:
Instead of using a complex mechanical lifting mechanism that pushes or pulls the load upward, the invention inverts the approach by rotating the main support elements to lever the wheels underneath the load. The load is lifted by creating a pivot point and using rotational motion to generate lifting force, reversing the conventional lifting approach.
2Ease of operation
If heavy loads like heat pumps are lifted using conventional methods, then transport is possible, but damage risk increases
Solution Approach 1:
The main support elements are designed to rotate dynamically during the lifting process, allowing the operator to control the lifting speed and force. This dynamic adjustment capability enables gentle lifting of heavy loads like heat pumps, reducing the risk of damage while maintaining ease of transport.
Solution Approach 2:
The crossbeams serve as intermediary structural elements that distribute the lifting force across multiple points on the load. By placing crossbeams across the load and attaching main support elements to them, the lifting force is distributed rather than concentrated, reducing the risk of damage to the load during lifting and transport.
3Ease of manufacture
If simple support structures are used, then the device is easy to manufacture, but secure attachment of heavy loads is difficult
Solution Approach 1:
The invention merges multiple functions into the crossbeam structure: structural support, attachment point for main support elements, and load distribution. The crossbeams are simply attached to the load (e.g., straddling it through openings), providing both structural integrity and attachment capability without complex manufacturing, yet maintaining sufficient strength for heavy loads.
