Cylindrical Twist Lock Tool for Corroded Containers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tools lack an efficient and safe method for securing and releasing twistlocks on intermodal shipping containers, especially under harsh weather conditions and when corrosion is present, which can make the twistlocks hazardous to handle.
Innovation Solution
A tool comprising an elongated shaft member with coupling members, made of sturdy materials like steel, designed to securely engage and disengage twistlocks by encircling the extending lever and allowing downward pull and rotation, facilitating easy handling and securing of containers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing tools are used to handle twistlocks, then basic operation is possible, but operational safety deteriorates under harsh weather conditions and corrosion
Solution Approach 1:
The tool acts as an intermediary device between the operator and the corroded twistlock mechanism. The coupling members engage with the twistlock components, allowing the operator to manipulate the lock without direct hand contact, thereby protecting against corrosion and harsh weather conditions while maintaining operational reliability
2Ease of operation
If direct handling of twistlocks is performed, then operation simplicity is maintained, but ease of operation deteriorates when corrosion is present
Solution Approach 1:
The tool provides a corrosion-resistant intermediary interface that engages with the twistlock mechanism. The coupling members are designed to interface with the twistlock components, allowing operators to manipulate corroded locks without direct contact, thereby maintaining ease of operation despite corrosion conditions
Solution Approach 2:
The tool appears to be a simple, robust device that can be easily replaced if damaged by corrosion or excessive force. This disposable approach ensures that operators always have a functional tool available, maintaining ease of operation without investing in complex, maintainable equipment
3Reliability
If no tool is used and direct manipulation is attempted, then device complexity is minimized, but reliability deteriorates due to safety hazards from corroded twistlocks
Solution Approach 1:
The tool is divided into distinct functional segments: the elongated shaft member for reach and leverage, and the coupling members for engagement with specific twistlock components. This segmentation allows each part to perform its specific function efficiently while keeping the overall device relatively simple in structure but effective in improving safety
Solution Approach 2:
The tool introduces a simple intermediary structure between the operator and the hazardous corroded twistlock. This mediator provides the necessary safety function without requiring complex mechanisms, thereby improving reliability while maintaining minimal device complexity
