Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional ISO tank containers face issues with residue buildup during cargo discharge, requiring extensive cleaning and reducing cost efficiency due to empty returns, while flexitank containers lack durability and are prone to damage, leading to potential environmental pollution.
Innovation Solution
An ISO tank container design incorporating a tank body with a first valve for discharge and a flexitank installed inside, connected via first and second tank connectors, allowing for easy cargo discharge and environmental control without additional valves, enhancing durability and flexibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a conventional ISO tank container is used, then durability and corrosion resistance are improved, but cargo discharge completeness deteriorates due to residue buildup
Solution Approach 1:
The container system is segmented into two functional parts: a durable outer tank body for structural integrity and a removable inner flexitank for cargo containment. This segmentation allows the flexitank to be completely removed after discharge, eliminating residue buildup issues while the tank body maintains its durability and corrosion resistance.
Solution Approach 2:
The cargo-containing flexitank is extracted as a separate removable component from the tank body. After cargo discharge, the flexitank can be completely taken out and disposed of, ensuring no residue remains in the tank body, thus achieving complete cargo discharge while preserving the durability of the tank structure.
2Stability of the object's composition
If a conventional ISO tank container is used, then structural stability is improved, but cleaning cost and time increase due to residue removal requirements
Solution Approach 1:
The flexitank is extracted as a disposable inner container that can be completely removed after cargo discharge. This eliminates the need for cleaning the tank body, as all cargo residue remains within the removed flexitank, thereby reducing cleaning time and cost while maintaining structural stability of the tank body.
Solution Approach 2:
The flexitank is designed as a disposable short-lived component that is replaced after each use. This disposable nature eliminates the need for expensive and time-consuming cleaning processes, while the durable tank body maintains its structural stability for repeated use.
3Productivity
If a flexitank container is used, then cargo discharge completeness is improved, but durability deteriorates due to damage during transport
Solution Approach 1:
The flexitank is nested inside the durable tank body, combining the advantages of both structures. The inner flexitank enables complete cargo discharge through its removable nature, while the outer tank body provides durability and protection during transport, effectively resolving the durability weakness of standalone flexitank containers.
4Adaptability or versatility
If a flexitank container is used, then adaptability is improved, but reliability deteriorates due to potential cargo leakage
Solution Approach 1:
The flexitank is nested within the protective tank body structure. The tank body provides a rigid protective shell that prevents damage and leakage during transport, while the flexible inner tank maintains adaptability for different cargo types. This nested configuration enhances reliability by preventing leakage while preserving adaptability.
Solution Approach 2:
The durable tank body serves as a protective cushioning layer around the flexitank before any damage can occur. This prior protection prevents impact and pressure damage to the flexitank during transport, thereby preventing cargo leakage and enhancing reliability while maintaining adaptability.
5Strength
If a conventional ISO tank container is used, then durability is improved, but cost efficiency deteriorates due to empty returns requiring cleaning
Solution Approach 1:
The flexitank is extracted and removed completely after cargo discharge, eliminating the need for cleaning the tank body before returning it empty. This reduces energy and cost consumption associated with cleaning operations, improving cost efficiency while the durable tank body is ready for immediate reuse.
Solution Approach 2:
The disposable flexitank is replaced rather than cleaned, eliminating expensive and energy-intensive cleaning processes. The durable tank body is reused without cleaning, significantly improving cost efficiency and reducing energy loss while maintaining durability.
6Strength
If a conventional ISO tank container is used, then structural integrity is improved, but versatility deteriorates due to difficulty in loading different cargo
Solution Approach 1:
The container system is segmented into a fixed tank body and a removable flexitank. This segmentation allows the flexitank to be easily removed and replaced with different types of flexitanks suited for different cargo, providing versatility while the tank body maintains its structural integrity.
Solution Approach 2:
The inner flexitank component is made dynamic and removable, allowing easy replacement for different cargo types. This dynamic design provides loading flexibility and versatility, while the static tank body maintains its structural integrity throughout the process.
