Pressurized Container Screening Means Prevents Additive Leakage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Pressurized fuel additive containers often result in additive products expanding and soiling the user's hands due to uncontrolled dispensing, as the internal pressure causes leakage outside the gas system's supply fitting during use.
Innovation Solution
A pressurized container design featuring a screening means with a deformable portion and a housing body that maintains contact with the sealing member, forming a containment zone to prevent additive product leakage, ensuring the products are directed into the gas system without soiling the user's hands.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the dispenser is pressed against the supply fitting to deliver additive products, then the additive products are dispensed into the gas system, but part of the additive products expand outside the supply fitting and soil the user's hands
Solution Approach 1:
A containment zone is introduced as an intermediary structure between the dispenser and the external environment. This containment zone, formed by the screening means and sealing member, captures and directs the additive products that would otherwise escape, preventing them from soiling the user's hands while maintaining dispensing functionality.
Solution Approach 2:
The screening means and containment zone are positioned to preemptively intercept additive products before they can escape outside the supply fitting. By establishing this containment structure in advance, the system prevents the harmful effect of soiling before it occurs, rather than addressing it after the fact.
2Ease of operation
If the internal pressure of the container is used to deliver additive products, then the dispensing operation is simplified, but uncontrolled expansion and leakage of additive products occur
Solution Approach 1:
The containment zone acts as an intermediary control mechanism that manages the high-pressure additive product flow. It provides a controlled transition zone where the pressurized products are contained and directed, preventing uncontrolled expansion while maintaining the simplicity of the dispensing operation.
Solution Approach 2:
The screening means and containment zone provide a protective buffer zone that absorbs and manages the high-pressure discharge of additive products. This pre-established containment structure cushions the pressure release, preventing direct uncontrolled expansion while maintaining operational simplicity.
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 containment zone effectively prevents additive products from escaping onto the container and the user's hands, ensuring efficient and clean dispensing into the motor vehicle's gas system.
Implementation Method 1
a deformable portion (13) which can be deformed during the passage of the dispenser (5) from the closed condition to the open condition, and vice versa
