Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a lack of commercially available transport containers that meet the necessary transport approval and comply with packaging instructions for transporting concentrated hydrogen peroxide in volumes ranging from 65 to 500 liters.
Innovation Solution
A transport container comprising a cuboid support frame and a liquid container made of pure aluminum, chromium-nickel steel, nickel-based alloy, or polyolefin-coated steel, equipped with a pressure equalization device, pressure relief valve, and closable openings for filling and removing hydrogen peroxide, ensuring safe and efficient transport.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If conventional transport containers (aluminum cylinders, tank containers, or tank trucks) are used for concentrated hydrogen peroxide, then small quantities or large quantities can be transported, but no commercially available container exists for volumes of 65 to 500 liters that meets transport approval requirements and packaging instruction P501 of the ADR
Solution Approach 1:
The support frame is divided into multiple receptacles (first, second, and optionally third receptacles) that can hold different quantities of hydrogen peroxide. This segmentation allows the container system to adapt to various transport volume requirements by selectively using one or multiple receptacles, thereby filling the gap for 65-500 liter transport volumes that were previously unavailable.
2Reliability
If a liquid container is made of pure aluminum, then it is suitable for transporting concentrated hydrogen peroxide, but the container must be pretreated by etching processes to remove metal from the inner wall
Solution Approach 1:
The liquid container undergoes pretreatment processes (etching, passivation, or coating) before being put into service for transporting concentrated hydrogen peroxide. This preliminary action prepares the inner surface to be chemically compatible with hydrogen peroxide, preventing unwanted reactions while maintaining the reliability of the container for long-term use.
3Reliability
If a pressure equalization device is added to the liquid container, then pressure equilibrium can be maintained during transport, but the device complexity increases
Solution Approach 1:
A pressure equalization device is introduced as an intermediary component between the liquid container interior and the external environment. This device mediates pressure differences by allowing air to enter or escape the receptacles, thereby maintaining pressure equilibrium during transport without requiring complex active control systems.
4Object-affected harmful factors
If a pressure relief valve is installed on the liquid container, then overpressure can be relieved to prevent leakage or rupture, but the device complexity and potential leakage points increase
Solution Approach 1:
A pressure relief valve is installed on the liquid container to provide preliminary protection against overpressure conditions. The valve is pre-configured to open at a specific pressure threshold, automatically relieving excess pressure before it can cause leakage or rupture of the container, thereby preventing harmful outcomes.
5Adaptability or versatility
If multiple receptacles are arranged in the support frame, then flexibility in transport volume is improved, but the weight of the stationary object increases
Solution Approach 1:
The support frame is segmented into multiple receptacles that can be selectively filled with hydrogen peroxide. This segmentation provides flexibility in transport volume by allowing the user to use only the necessary number of receptacles, thereby improving adaptability while the modular design helps manage the overall weight distribution.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution provides a safe and efficient means to transport concentrated hydrogen peroxide by maintaining pressure equilibrium, preventing leakage, and distributing weight evenly, thus ensuring the container's structural integrity and safety during transport.
