Pallet Container Tubular Lattice Frame Transportation Securing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional pallet containers without solid metal frames and corner posts lack effective constructive devices for optimal transportation securing, particularly for hazardous liquid filling materials, leading to instability during transportation.
Innovation Solution
A pallet container with a tubular lattice frame and a metal transportation securing eye fastened to the pallet top deck in all four corner regions, allowing for secure lashing down with lashing straps, which prevents slipping during transportation by distributing tensile forces effectively through the lattice frame.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Weight of moving object
If conventional pallet containers without solid metal frames are used, then weight is reduced and ease of manufacture is improved, but transportation security and stability deteriorate
Solution Approach 1:
The pallet container combines a tubular lattice frame made of metal tubes with a plastics inner container and supporting casing. This composite structure provides the strength and stability of metal while maintaining reduced weight compared to solid metal frames, resolving the contradiction between weight reduction and transportation security.
Solution Approach 2:
The frame is segmented into a tubular lattice structure with corner posts, horizontal tubes, and vertical tubes rather than using solid metal frames. This segmentation provides sufficient structural strength for transportation security while reducing overall weight, addressing the contradiction between reliability and weight.
2Ease of manufacture
If tubular lattice frame without solid metal corner posts is used, then ease of manufacture is improved and weight is reduced, but device complexity for securing increases
Solution Approach 1:
Transportation securing eyes are pre-fastened to the pallet top deck in all four corner regions during manufacturing. This preliminary action eliminates the need for additional constructive devices or complex securing mechanisms during use, maintaining ease of manufacture while providing simple and effective securing capability.
Solution Approach 2:
The screw fasteners serve dual functions: they secure the lattice frame structure and simultaneously function as mounting points for transportation securing eyes. This multi-functionality reduces the number of separate components needed, simplifying the overall device while maintaining ease of manufacture.

AI summary
A pallet container for storing and transporting in particular hazardous liquid filling materials, includes an exchangeable plastics inner container and a supporting casing which closely encloses the plastics inner container and is made of a tubular lattice frame which is fastened to the upper outer rim on the pallet top deck of a rectangular bottom pallet. A transportation securing eye made of metal is provided and fastened on the pallet top deck of the bottom pallet (12) in each of all four corner regions externally at the bottommost horizontally peripheral lattice tube of the tubular lattice frame.
