Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional pressure control device is used, then pressure control functionality is provided, but the device is costly, complex, and prone to malfunction
Solution Approach 1:
The pressure control device is segmented into distinct functional components: a closing element for sealing the passage opening, a protruding guide element for positioning and guiding the closing element, and a pressure chamber for housing the propellant. This segmentation allows each component to be optimized independently and simplifies the overall structure, reducing complexity while maintaining reliability.
Solution Approach 2:
The closing element is designed to surround and enclose the protruding guide element, creating a nested configuration. This nesting approach maximizes space utilization within the partition wall, reduces the overall device volume, and simplifies assembly by integrating multiple functions into a single compact structure.
2Reliability
If a conventional pressure control device is used, then pressure control is provided, but material consumption and manufacturing costs are high
Solution Approach 1:
The closing element surrounds the protruding guide element, creating a nested configuration that minimizes the total volume of material required. This nested structure eliminates the need for separate housing components and reduces material consumption while maintaining the necessary functional integrity of the pressure control device.
Solution Approach 2:
The guide element and closing element are merged into an integrated assembly where the closing element serves dual purposes: guiding the propellant flow and sealing the passage opening. This merging eliminates the need for separate guide and sealing components, reducing material consumption and manufacturing complexity.
3Shape
If the pressure control device is positioned centrally in the partition wall, then symmetry is achieved, but the central position is occupied preventing efficient filling
Solution Approach 1:
The pressure control device is deliberately positioned asymmetrically within the partition wall, offset from the central axis. This asymmetric positioning frees up the central region of the partition wall, allowing for the integration of a propellant filling valve that can access the propellant compartment from the outside, thereby improving filling efficiency without compromising the structural integrity of the partition wall.

Function Achieved in This Case
The solution provides reliable, cost-effective, and accurate pressure control with reduced material consumption, minimizing malfunctions and enabling efficient filling of pressurized fluid containers without the need for new filling equipment.
Implementation Method 1
a closing element (5) attached to the partition wall moveable between a passage opening release position and a passage opening closing position... the closing element gets around (surrounds) the protruding guide element enabling a very compact construction
Implementation Method 2
the closing element and the protruding guide element are gas-tight enclosing a pressure chamber. This gas-tight enclosed pressure chamber when at least partially compressed is exerting a pressure on the inside of the closing element
