Compact Handling Device for ISO Containers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing handling devices for ISO668 and ISO1161 standard containers exceed the European road gauge and aircraft hold dimensions, resulting in excessive transverse projection and inefficiencies during transport and unloading, particularly due to their size and orientation-dependent locking mechanisms.
Innovation Solution
A compact handling device with a movable gib and main body, featuring a stud with a shaft and nut mechanism, allowing for reduced transverse projection and secure locking independent of orientation, enabling efficient handling and securing of containers within the gauge limits.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional handling device is used to engage with the container corner, then the container can be securely gripped and handled, but the device exceeds the European road gauge and aircraft hold dimensions due to excessive transverse projection
Solution Approach 1:
The gib is made movable relative to the main body, allowing it to rotate between a first position (for engagement) and a second position (for locking). This dynamic mechanism enables the device to adapt its configuration to achieve both secure gripping and reduced transverse projection, resolving the contradiction between grip security and dimensional constraints
Solution Approach 2:
The handling device is divided into distinct functional components: the main body, the movable gib, the stud, and the nut. This segmentation allows each component to perform its specific function independently, enabling the gib to move for engagement while the main body maintains a compact profile that fits within road gauge and aircraft hold dimensions
2Stability of the object's composition
If the handling device is designed to remain fixed during transport, then the container securing is improved, but the device complexity increases due to orientation-independent locking requirements
Solution Approach 1:
The nut mechanism automatically locks the gib in the first position when the handling device is correctly oriented during transport. The stud and nut arrangement creates a self-locking system that maintains the gib's position without requiring additional active components or complex control systems, thus achieving stable fixing with minimal added complexity
Solution Approach 2:
The handling device is designed to perform multiple functions: gripping the container corner, locking in various orientations, and remaining fixed during transport. The combination of the movable gib, stud, and nut creates a universal mechanism that handles both engagement and securing functions, reducing the need for separate components and simplifying the overall device structure
