VSEngineering Contradiction Analysis

1Reliability

If data lines are arranged externally for pressure sensors in solenoid valve manifolds, then sensor signals can be transmitted, but the wiring configuration becomes complicated

Engineering Contradiction:
Improvesensor signal transmissionVSAvoidwiring configuration
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent integrates the data lines for pressure sensors directly into the manifold block structure, merging the signal transmission function with the manifold body. This eliminates separate external wiring for sensor connections, thereby simplifying the overall wiring configuration while maintaining reliable signal transmission from sensors to control devices.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The manifold block serves as an intermediary structure that incorporates both fluid flow pathways and electrical data line pathways. By embedding data lines within the manifold block, the patent creates an integrated medium that simultaneously handles pneumatic/hydraulic functions and electrical signal transmission, reducing the need for separate external wiring.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Adaptability or versatility

If data lines are arranged externally, then connection flexibility is maintained, but wiring operations become more complex

Engineering Contradiction:
Improveconnection flexibilityVSAvoidwiring operations
Core Design Contradiction:
Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The data lines are pre-integrated into the manifold block structure during manufacturing, with connection points and routing predetermined. This preliminary integration eliminates the need for complex field wiring operations, as connections are established during assembly rather than requiring separate wiring steps during installation or maintenance.

Inventive Principle:
Principle #10Preliminary action

3Ease of operation

If external wiring is used for sensor data lines, then installation is simpler, but the overall system configuration becomes more complex

Engineering Contradiction:
Improveinstallation simplicityVSAvoidsystem configuration
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

By merging the data line routing with the manifold block structure, the patent reduces the number of separate components and connection points required. This integration simplifies the overall system configuration by eliminating external wiring harnesses and reducing the complexity of system assembly, while maintaining ease of installation through standardized connection interfaces.

Inventive Principle:
Principle #5Merging (Combining)
