Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional fluidic connection components are used for planar structures, then sealing performance can be achieved, but device complexity and handling difficulty increase
Solution Approach 1:
The patent merges the planar structure with the adapter piece by directly connecting the fluid channel outlet to the adapter, eliminating the need for separate connection components. This integration reduces device complexity while maintaining sealing performance through the direct fluid-tight connection between the planar structure's fluid channel and the adapter's fluid conduit.
Solution Approach 2:
The adapter piece serves multiple functions: it provides sealing, connects to the planar structure, and interfaces with external fluidic systems. This multi-functionality reduces the number of separate components needed, simplifying the overall device while ensuring reliable sealing under high pressure.
2Reliability
If high-pressure sealing is achieved through traditional fittings, then leak-free connection is possible, but dead volume increases
Solution Approach 1:
The patent extracts and eliminates unnecessary intermediate components and sealing elements that traditionally increase dead volume. By directly connecting the fluid channel to the adapter piece with minimal intervention, the design removes excess material and space while maintaining leak-free connection through precise fluid-tight accommodation.
Solution Approach 2:
The patent transitions from traditional linear connection paths to a more compact three-dimensional arrangement where the fluid channel outlet directly interfaces with the adapter piece. This dimensional optimization reduces the flow path length and eliminates dead volume pockets while maintaining sealing integrity under high pressure.
3Volume of moving object
If planar structures with integrated fluid channels are used, then device compactness is improved, but connection and handling difficulty increases
Solution Approach 1:
The adapter piece acts as an intermediary between the planar structure's fluid channel and external fluidic components. It provides a standardized interface that simplifies connection and handling while maintaining the compactness of the integrated planar design, making the device easier to operate without compromising space efficiency.
4Stress or pressure
If high operational pressures are accommodated, then sealing requirements increase, but component simplicity is reduced
Solution Approach 1:
The patent combines the sealing function directly into the adapter piece's fluid-tight accommodation structure, eliminating the need for separate sealing mechanisms. This integration maintains component simplicity while accommodating high operational pressures through the direct, robust connection between the planar structure and adapter piece.
