Two-Component Pressurized Can with Segregating Disk
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional two-component pressure cans lack sufficient space to accommodate larger quantities of the second component, such as fire retardants, which are incompatible with the main component and must be mixed immediately before use, limiting the storage and application of two-component systems like assembly foams and paints.
Innovation Solution
A two-component pressure can design featuring a separating disk with a central opening and a closure element, allowing for adjustable volume distribution between upper and lower chambers, enabling precise mixing ratios and separation of components until activation, using a trigger-actuated opening device to mix the contents.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a separate inner sleeve is used to hold the second component, then the components are strictly separated during storage, but the space available for the second component is insufficient
Solution Approach 1:
The can is divided into two chambers by a separating disk with a peripheral necking, allowing each chamber to hold one component. This segmentation provides strict separation during storage while maximizing the volume available for the second component in the lower chamber.
Solution Approach 2:
The separating disk with peripheral necking creates a three-dimensional separation structure that optimizes space utilization. The necking arrangement allows the second component to occupy the entire lower chamber volume while maintaining reliable separation.
2Reliability
If the second component is stored in a separate sleeve, then contamination is prevented, but the mixing thoroughness is insufficient
Solution Approach 1:
The separating disk with peripheral necking ensures complete separation of components during storage, preventing contamination. Upon activation, the closure element is detached and both components mix thoroughly in the same chamber, ensuring uniform distribution of additives like fire retardants.
Solution Approach 2:
The separating disk acts as an intermediary structure that maintains separation during storage but allows complete mixing when activated. The peripheral necking design ensures that when the separator is removed, both components can mix thoroughly without contamination.
3Quantity of substance
If the can body is divided into chambers, then larger quantities of second component can be accommodated, but the device complexity increases
Solution Approach 1:
The can body is segmented into upper and lower chambers by a separating disk with peripheral necking. This simple segmentation allows large quantities of the second component to be stored in the lower chamber while maintaining a relatively simple overall structure.
Solution Approach 2:
The separating disk serves multiple functions: it separates the two components during storage, provides structural support for the closure element, and facilitates thorough mixing when activated. This multi-functionality reduces the need for additional complex components.
4Adaptability or versatility
If a peripheral necking with separating disk is used, then adjustable volume distribution is achieved, but the manufacturing complexity increases
Solution Approach 1:
The peripheral necking with separating disk creates adjustable volume distribution between chambers. The necking can be positioned at different heights to achieve various mixing ratios, and this segmentation can be integrated into conventional can manufacturing processes.
Solution Approach 2:
The separating disk with peripheral necking is pre-installed in the can body during manufacturing, establishing the volume distribution configuration before the components are filled. This preliminary action simplifies the overall manufacturing process by integrating the separation structure into the can fabrication.

Function Achieved in This Case
Enables the storage and efficient dispensing of two-component systems by allowing larger quantities of the second component, ensuring strict separation during storage and thorough mixing before use, accommodating various mixing ratios and enhancing the application of foams, paints, and adhesives.
Implementation Method 1
The main component also contains a liquid gas component, which serves to expel and foam the contents of the can.
Implementation Method 2
the second component contains, among other components, a crosslinking agent that is able to react with the reactive isocyanate groups of the main component
