Pallet Base Frame Corner Feet with Stop Body for Stacking Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pallet-like base frames for transport and storage containers of liquids face instability issues when stacked due to manufacturing tolerances, leading to potential tilting and misalignment, which can result in safety hazards during transportation and storage, especially for dangerous goods.
Innovation Solution
The base frame design includes corner feet with a stop body on the lower supporting surface, creating a defined bearing rim for supporting the outer casing, ensuring a quasi-centered arrangement and maintaining a consistent distance between the foot frame and the outer casing, thereby preventing misalignment and enhancing stacking stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manufacturing tolerances are relaxed to facilitate assembly, then ease of operation is improved, but positioning precision and stacking stability deteriorate
Solution Approach 1:
The stop body acts as an intermediary element between the foot frame and the outer casing. It mediates the positioning relationship by physically limiting the horizontal distance, thereby translating operational ease into precise positioning without requiring tight manufacturing tolerances on the foot frame or outer casing dimensions.
Solution Approach 2:
The stop body changes the effective geometric parameter of the base frame by introducing a fixed offset distance. This parameter change transforms the positioning problem from one of precise dimensional manufacturing to one of simple geometric constraint, allowing tolerant components to achieve precise stacking alignment.
2Volume of moving object
If the distance between foot frame and outer casing is minimized to improve stacking compactness, then space utilization is improved, but stability and alignment precision deteriorate
Solution Approach 1:
The stop body serves as a mediating element that maintains a controlled distance between the foot frame and outer casing. This intermediary structure ensures that while the distance is minimized for compactness, the stop body still provides sufficient positioning precision and stability to prevent tilting and misalignment during stacking.

AI summary
A pallet-like base frame-includes a floor for supporting the inner container. Corner feet and central feet are mounted on a foot frame attached to the floor of the base frame. At least one of the corner feet includes a corner foot body with a front wall and partial bodies formed laterally of a center axis of the front wall. The partial bodies respectively include an upper supporting surface formed on the circumferential rim of the front wall for connecting the corner foot with the floor and a lower supporting surface with a connecting region for connecting the corner foot with the foot frame. The lower supporting surface of at least one partial body has a stop body arranged between a circumferential rim of the front wall and the connecting region, which stop body, due to its distance from the circumferential rim, defines a bearing rim for supporting the base frame on an outer casing of a transport and storage container.
