Integral Container Frame Bars for Universal Truck Securing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing containers face issues with compatibility and safety during transportation due to varying frame bar shapes, leading to insecure attachment and cumbersome manufacturing processes, especially when using different securing systems on trucks or trailers.
Innovation Solution
A container design featuring frame bars that are integral with the floor, made from a single sheet bent to form ribs, ensuring compatibility with various securing systems and allowing for universal manufacturing, with the frame bars and floor having equal thickness for reduced weight and increased strength.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If frame bars are made with different shapes to match specific securing systems, then compatibility with particular trucks is improved, but adaptability to different securing systems deteriorates
Solution Approach 1:
The frame bars are designed with a universal T-shaped cross-section that can be clamped by different types of securing systems (claws, chains, hooks) regardless of their specific configuration. This single standardized shape replaces multiple specialized shapes, allowing the same container to be securely attached to various trucks and trailers without modification.
2Reliability
If frame bars are made with complex shapes to match specific securing systems, then attachment security is improved, but ease of manufacture deteriorates
Solution Approach 1:
The container body is divided into modular components (floor, walls, roof, frame bars) that can be manufactured independently using standardized processes. The frame bars are produced as separate T-shaped elements that are subsequently attached to the container body, allowing for simplified manufacturing of each component while maintaining secure attachment capability.
3Adaptability or versatility
If frame bars have varied shapes for different trucks, then securing system compatibility is improved, but automated manufacturing difficulty increases
Solution Approach 1:
The frame bar design uses a standardized T-shaped cross-section with consistent dimensions that can be produced by automated forming or extrusion processes. This uniform geometric parameter allows robotic welding or fastening systems to attach frame bars to container bodies without requiring complex adaptive programming for different frame shapes.

AI summary
The present invention relates to a container frame (1) for forming a container (100) to be loaded on a truck by a skip loader, hooklift, chainlift or cable lift system, the frame comprising: - a floor (10), configured to support a load arranged in or on the container, and - two longitudinal frame bars (20), arranged underneath the floor to support the floor and each comprising a frame rib (21), herein the frame bars extend parallel to each other and downwardly protrude from the floor, for example in a direction perpendicular to the plane of the floor, the frame bars and the floor are integral with each other and formed from a flat sheet (F), wherein the floor is formed from a central part (C) of the flat sheet, and wherein the frame bars are formed by opposed side parts (S) of the flat sheet, which are bent downward, for example perpendicular relative to the central part.
