Pallet Base Frame With U-Shaped Central Feet For Torsion Resistance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Base frames for transport and storage containers, particularly those for liquids, face challenges in stability and torsion resistance, which can lead to storage breakdown and damage during handling and transport, especially under asymmetrical impacts.
Innovation Solution
A pallet-like base frame design featuring central feet with a U-shaped cross section and edge webs that connect the base wall and journal walls, providing increased torsion resistance and stability, and allowing for production from a flat sheet metal blank with minimal material usage, along with reinforcement features like box-shaped projections and reinforcement seams to enhance stiffness and protect against forklift impacts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If central feet extend on a single axis along a foot frame side, then the base frame structure is simple, but the torsion resistance is insufficient
Solution Approach 1:
The central feet are designed with a U-shaped cross-section that extends in multiple directions (transversely and longitudinally) rather than along a single axis. This multi-axial configuration transforms the structural geometry from one-dimensional to two-dimensional, providing enhanced torsion resistance while maintaining manufacturing simplicity through the profile body design
2Stability of the object's composition
If corner feet extend across a corner area with multi-axial body shape, then the torsion resistance is improved, but the material usage increases
Solution Approach 1:
The U-shaped cross-section of the central feet provides localized reinforcement at critical stress points (the journal walls and edge web connections) while maintaining a relatively lightweight overall structure. The profile body configuration concentrates material where torsional stresses are highest, rather than uniformly distributing material throughout the entire foot structure
3Reliability
If the base frame is designed to absorb impact loads, then the protection against damage is improved, but the structural complexity increases
Solution Approach 1:
The base frame is designed with impact absorption capability built into the fundamental structure of the central feet through their U-shaped cross-section and multi-axial configuration. This preliminary structural design allows the frame to withstand asymmetrical impacts and torsional loads without requiring additional protective components or complex shock-absorbing mechanisms

AI summary
A pallet-like base frame includes corner feet and a floor for supporting an inner container. Central feet made of metal are arranged between the corner feet, and which are attached to a foot frame, to which the floor of the base frame as well as an outer jacket of the inner container are fastened. At least one central foot of the base frame encompasses a profile body, which encompasses a U-shaped cross section, comprising a base wall, an outer journal wall and an inner journal wall, wherein the base wall and the journal walls embody an axial edge web at axial end areas of the profile body in a plane at right angles to a longitudinal axis of the profile body.
