Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the tubular reservoir is used with capillary retention to hold fluid composition, then the fluid can be retained in the reservoir, but the restitution of the fluid composition is poor and samples become too concentrated
Solution Approach 1:
The invention divides the sealed chamber into two distinct parts: the tubular reservoir that retains fluid via capillary action and the pressurization chamber that applies pressure. This segmentation allows the reservoir to hold fluid while the pressurization chamber enables complete restitution without concentration issues.
Solution Approach 2:
The pressurization chamber acts as an intermediary mechanism between the stored fluid and the external environment. By introducing pressurized gas into this intermediate chamber, the system overcomes capillary retention forces and achieves complete fluid restitution without direct contact between the fluid and atmospheric pressure.
2Reliability
If the chamber remains sealed to protect the fluid composition, then contamination is prevented, but air intake is blocked and fluid flow is hindered
Solution Approach 1:
The system performs preliminary sealing to protect the fluid composition during storage and transport. The sealed chamber maintains fluid integrity until the moment of use, when the pressurization mechanism is activated to break the seal and enable complete fluid restitution.
Solution Approach 2:
The chamber transitions from a static sealed state to a dynamic pressurized state. The pressurization member can move axially to decrease chamber volume and introduce pressurized gas, dynamically changing the chamber's properties from sealed protection mode to active restitution mode.
3Stress or pressure
If the pressurization member moves axially to decrease chamber volume, then pressurization is achieved, but the sealed chamber prevents air intake
Solution Approach 1:
The pressurization member continuously decreases the chamber volume through axial movement, maintaining pressurization throughout the restitution process. This continuous compression ensures complete fluid expulsion from the reservoir while the frangible seal breaks to allow air intake.
Solution Approach 2:
The system changes the physical parameters of the chamber by moving the pressurization member axially. This movement decreases chamber volume and increases pressure, while simultaneously triggering the frangible seal to break and allow atmospheric pressure equalization through air intake.
