Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing chemical storage containers for hazardous substances like hydrogen peroxide are complex, prone to improper alignment during extraction and filling, inefficient in sterilization cycles, and susceptible to decomposition due to interaction with plastic materials, leading to uneven gas buildup and waste.
Innovation Solution
A rupture-resistant container with a symmetrical, hockey puck-like geometry and interchangeable septums for easy alignment, allowing controlled gas permeation and minimizing chemical-plastic interaction, featuring a shell with thinner areas for gas release and a self-sealing septum for safe extraction and filling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a multi-cell package design with compartments is used to store hydrogen peroxide, then the chemical can be stored in organized sections, but the complexity and expense of the extraction unit increases due to the need for precise alignment of holes with needles
Solution Approach 1:
The container is divided into multiple cells within a single compartment, allowing organized storage of hydrogen peroxide in discrete units while maintaining overall structural simplicity for extraction
Solution Approach 2:
The extraction system is designed to handle multiple cells through a universal mechanism that can extract from any cell without requiring cell-specific alignment procedures, making the system adaptable to multi-cell configurations
2Stability of the object's composition
If precise alignment of holes with needles is required for extraction, then the multi-cell package structure is maintained, but the ease of operation decreases due to alignment requirements for each compartment
Solution Approach 1:
Multiple cell extraction functions are merged into a single operational mechanism that can service any cell without requiring separate alignment procedures, combining the extraction capability across all compartments
Solution Approach 2:
The extraction system incorporates self-aligning features or universal access mechanisms that automatically adapt to the cell position, eliminating the need for manual precise alignment by the operator
3Ease of manufacture
If plastic materials are used in the container to store hydrogen peroxide, then the container can be manufactured with various shapes and structures, but the chemical stability decreases due to catalytic decomposition
Solution Approach 1:
The container uses different materials for different functions: plastic for structural components and inert material for the containment surface that contacts hydrogen peroxide, providing both manufacturing ease and chemical stability
Solution Approach 2:
The container employs composite construction combining plastic structural elements with inert liner materials that resist catalytic decomposition, achieving both formability and chemical compatibility
4Strength
If gas permeation is not permitted in the container, then the structural integrity is maintained, but gas buildup occurs leading to pressure increase and potential rupture
Solution Approach 1:
The container incorporates porous or gas-permeable materials in specific regions that allow controlled gas transmission while maintaining overall structural integrity and containing the liquid hydrogen peroxide
Solution Approach 2:
A gas permeation layer or membrane acts as an intermediary between the hydrogen peroxide solution and the external environment, allowing gas to pass through while maintaining the container's structural containment function
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 container ensures safe and efficient use of hydrogen peroxide as a sterilant by reducing decomposition rates, simplifying extraction and filling processes, and preventing gas buildup, thus minimizing waste and maintaining the chemical's effectiveness.
Implementation Method 1
the material from which at least one of the first and second portions is constructed should permit permeation of non-hazardous gases that might form in the chamber 14 as a result of decomposition of the chemical or the like
Implementation Method 2
The rims of the two portions are then bonded together ultrasonically or using a suitable adhesive to create a seal

AI summary
A container is provided for holding a chemical compound or mixture. Areas are provided on the surface of the container which allow for gaseous by-products from the chemical contained within the container to permeate from a chamber through the surface of the container. A septum is over-molded into the surface of the container. The septum is formed in such a manner that it provides a sealing effect to close an opening in the container.
