Partitioned Dispenser Container for Constant Pressure Dosing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Pressure-controlled dispenser containers are complex and costly due to the integration of high-pressure canisters, which complicates manufacturing and increases production costs, while existing dispensers struggle to maintain constant pressure over time, especially when dispensing high-viscous substances or in medical contexts.
Innovation Solution
A dispenser container with a metal shell enclosing both high-pressure and low-pressure chambers, separated by a partition wall with a valve for controlled fluid release, where the metal shell provides structural integrity and a fluid-tight seal, reducing the need for separate canisters and simplifying manufacturing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a separate high-pressure canister is integrated into the dispenser container, then pressure control is achieved, but device complexity increases
Solution Approach 1:
The invention merges the high-pressure and low-pressure chambers into a single integrated dispenser container body, eliminating the separate high-pressure canister. The partition wall divides the internal volume into two pressure zones, allowing pressure control functionality to be achieved without the complexity of a separate canister system.
Solution Approach 2:
The metal shell serves multiple functions: it provides the outer structural boundary, contains both high-pressure and low-pressure chambers, and replaces the traditional separate canister. This multi-functional design reduces the number of components while maintaining pressure control capability.
2Reliability
If a separate high-pressure canister is integrated into the dispenser container, then pressure control is achieved, but manufacturing complexity and costs increase
Solution Approach 1:
By combining the high-pressure and low-pressure chambers into a single container body with a partition wall, the manufacturing process is simplified. Instead of assembling a separate canister into the container, the partitioned structure can be formed in fewer steps, reducing manufacturing complexity and costs.
3Strength
If the metal shell delimits the high-pressure chamber, then structural integrity is improved, but sealing complexity increases
Solution Approach 1:
The sealing zone is created as a localized feature on the partition wall that interfaces with the metal shell. This localized sealing approach concentrates the sealing function in a specific area, making the sealing structure more manageable and less complex while maintaining the structural integrity provided by the metal shell.
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 metal shell maintains constant pressure, extends the shelf life, and allows for more versatile fluid containment, reducing manufacturing complexity and costs while ensuring accurate dosing and high-quality sealing.
Implementation Method 1
a valve mounted into the partition wall in a substantially fluid-tight manner, which valve is configured for a controlled release of fluid from the high-pressure chamber to the low-pressure chamber
