Loading Vehicle Spring Compensation for Uneven Container Stacks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing loading vehicles for block storage arrangements experience significant one-sided stress and moment loads due to unevenly stacked containers, which can lead to excessive wear and tear without requiring a stiffer supporting structure.
Innovation Solution
A moment compensation arrangement using spaced-apart spring elements that adapt to the inclination of the container stack, counteracting one-sided stress through opposing spring forces, allowing the loading vehicle to balance moments and reduce uneven loads.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the loading vehicle uses a lifting device to raise container stacks, then containers can be inserted into and removed from receiving areas, but significant one-sided stress and moment loads occur due to unevenly stacked containers
Solution Approach 1:
The patent introduces a moment compensation arrangement with spring elements that generate counteracting forces to balance the moment loads caused by unevenly stacked containers. The spring elements are positioned to create opposing moments that compensate for the one-sided stress on the lifting device, effectively reducing the net moment load on the loading vehicle structure.
Solution Approach 2:
The patent changes the mechanical parameters of the lifting system by incorporating spring elements with specific stiffness and pre-load characteristics. These spring elements deform under load to provide dynamic moment compensation, allowing the system to adapt to varying container stack conditions while maintaining structural integrity.
2Strength
If the supporting structure is stiffened to handle moment loads, then structural strength increases, but device complexity and assembly difficulty increase
Solution Approach 1:
The patent introduces a moment compensation arrangement as an intermediary system between the lifting device and the supporting structure. This arrangement includes spring elements that actively compensate for moment loads, allowing the supporting structure to remain less complex while still handling the loads effectively. The intermediary system absorbs the complexity rather than requiring the supporting structure to be over-engineered.
3Strength
If spring elements are used for moment compensation, then one-sided loads are mitigated, but device complexity increases
Solution Approach 1:
The moment compensation arrangement is segmented into multiple independent spring elements positioned at different locations on the loading vehicle. Each spring element handles a portion of the moment compensation task, allowing the system to distribute the complexity across multiple simple, modular components rather than requiring a single complex mechanism.
