Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If mechanical valve trim is used in fire protection systems, then the system can be operated and controlled mechanically, but the installation space required is large and maintenance requires on-site personnel

Engineering Contradiction:
Improvemechanical operation capabilityVSAvoidinstallation space
Core Design Contradiction:
Ease of operationVSArea of stationary object

Solution Approach 1:

The patent replaces traditional mechanical valve trim with an electrically actuated valve assembly that uses solenoid valves and electronic control components. This substitution eliminates the need for large mechanical operating mechanisms while maintaining valve control functionality, thereby reducing installation space requirements.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent extracts the essential control function from the mechanical valve trim and implements it through separate electrical components (solenoid valves, controllers, sensors). This allows the mechanical components to be minimized or eliminated while preserving the core operational capability through electrical actuation.

Inventive Principle:
Principle #2Taking out (Extraction)

2Ease of operation

If mechanical valve trim is used in fire protection systems, then the system can be controlled locally, but maintenance and troubleshooting require on-site personnel observation and operation

Engineering Contradiction:
Improvelocal control capabilityVSAvoidmaintenance accessibility
Core Design Contradiction:
Ease of operationVSEase of repair

Solution Approach 1:

The patent incorporates sensors, detectors, and communication interfaces that provide real-time feedback on system status, valve position, and operational parameters. This feedback mechanism enables remote monitoring and diagnostics, allowing maintenance personnel to assess system conditions and troubleshoot issues without being physically present at the installation site.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The patent replaces mechanical control and indication mechanisms with electrical and electronic systems that can transmit operational data remotely. This substitution enables maintenance personnel to monitor and diagnose system issues through electronic interfaces rather than requiring direct mechanical interaction at the site.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

3Area of stationary object

If electrical components are used to reduce installation space, then the space requirements are reduced, but the system complexity increases

Engineering Contradiction:
Improveinstallation spaceVSAvoidsystem complexity
Core Design Contradiction:
Area of stationary objectVSDevice complexity

Solution Approach 1:

The patent employs a controller that performs multiple functions including valve actuation, system monitoring, data logging, and communication. By consolidating these functions into a single multi-functional device, the system achieves space reduction without proportionally increasing complexity, as one component handles multiple tasks.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent combines electrical actuation components, sensing elements, and control logic into an integrated assembly. This merging of functions into unified components reduces the overall space required compared to separate mechanical systems while managing complexity through integration rather than proliferation of discrete parts.

Inventive Principle:
Principle #5Merging (Combining)

AI summary

Automatic fluid control assemblies and methods for fire protection include an arrangement of electrically operated control points, a valve body and a controller to operate the fluid control assembly. The automatic fluid control assembly has an inlet, an outlet and a valve body to control flow between the inlet and the outlet. An electric latch includes a first electrically operated control point and a second electrically operated control point in fluid communication with a control line to control the flow of fluid from the inlet to the valve body and outlet. The methods of fluid control include controlling a plurality of electrically operated control points to perform any one of: a leak test, a trip test, a flow test, a water delivery test, and a validation test of a non-trip condition and a trip condition.
