Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple driving assemblies are used in fluid control systems, then each fluid element can function independently, but the wiring structure becomes complicated and integration is hindered
Solution Approach 1:
The patent combines multiple driving assemblies into a single integrated assembly where multiple stator assemblies share common housing portions and electrical connection structures. The first and second stator assemblies are integrated within shared housing portions (first housing portion and second housing portion), eliminating the need for separate wiring harnesses for each assembly and reducing overall wiring complexity while maintaining independent functionality of each fluid control element
Solution Approach 2:
The housing portions serve multiple functions: they provide structural enclosure for the stator assemblies, contain the electrical connection pins, and facilitate both mechanical mounting and electrical connectivity. The first housing portion and second housing portion both serve as protective enclosures and electrical connection interfaces, reducing the need for additional dedicated wiring components
2Ease of manufacture
If electrical components are exposed for connection, then wiring can be established, but the electrical signal transmission stability and component protection are compromised
Solution Approach 1:
The electrical transmission pins are nested within the housing portions, with the first electrical transmission pin located inside the first housing portion and the second electrical transmission pin inside the second housing portion. This nested arrangement protects the electrical connection elements while maintaining their electrical connectivity functions, as the housing portions serve as protective enclosures that contain the pins while allowing electrical signals to pass through
