Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the solenoid valve manifold is disposed apart from the air cylinder, then the system layout flexibility is improved, but the air pipe length increases causing increased air consumption and response delay
Solution Approach 1:
The patent replaces the mechanical pneumatic signal transmission system with an electrical signal transmission system. Lead wires are used to transmit control signals between the solenoid valve manifold and air cylinders, eliminating the need for long air pipes and associated air consumption while maintaining layout flexibility
2Adaptability or versatility
If the solenoid valve manifold is disposed apart from the air cylinder, then the system layout flexibility is improved, but the air pipe length increases causing response delay
Solution Approach 1:
The patent substitutes electrical signal transmission via lead wires for mechanical pneumatic signal transmission through air pipes. Electrical signals propagate much faster than pneumatic signals, significantly reducing response delay while allowing the solenoid valve manifold to be disposed at flexible locations
3Speed
If the solenoid valve manifold is divided into multiple sections, then the proximity to air cylinders is improved, but the system structure becomes complex requiring multiple serial transmission units or extended lead wires
Solution Approach 1:
The patent divides the solenoid valve manifold into multiple sections or assemblies, each capable of being independently connected to air cylinders. This segmentation allows each section to be positioned close to its corresponding air cylinder, improving signal transmission speed while maintaining a relatively simple overall structure through modular design
4Loss of substance
If multiple valve assemblies are used, then the proximity to air cylinders is improved reducing air consumption, but the lead wire connection structure becomes complex
Solution Approach 1:
The patent employs universal lead wire connection structures that can be used across multiple valve assemblies. Standardized connectors and wiring patterns allow the same connection methodology to be applied repeatedly, reducing the perceived complexity despite the increased number of assemblies. The lead wires serve multiple functions including signal transmission and electrical connection

AI summary
A plurality of valve assemblies having a plurality of manifold valves assembled are electrically coupled in a row via lead wire assemblies to transmit a power signal for driving solenoids of the manifold valves in parallel from the valve assembly at a proximal side of the row to the valve assembly at a leading end side via the manifold valves of the valve assemblies and the lead wire assemblies.
