Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the valve cage is designed as a modular assembly with multiple components (holding element, piston guide element, throttle elements), then configuration flexibility and adaptability are improved, but device complexity increases

Engineering Contradiction:

Improveconfiguration flexibilityVSAvoidassembly structure

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The valve cage is divided into modular components including a holding element, piston guide element, and multiple throttle elements that can be independently selected and assembled. This segmentation enables configuration flexibility for different fluid applications while maintaining manageable complexity through standardized connection interfaces.

Inventive Principle:

Principle #1Segmentation

2Ease of operation

If the valve cage components are connected via screw threads or flanges, then ease of assembly and disassembly is improved, but device complexity increases due to additional connection elements

Engineering Contradiction:

Improveassembly simplicityVSAvoidconnection structure

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The valve cage components are pre-configured with standardized screw thread or flange connections that enable quick assembly and disassembly without requiring complex fastening procedures. The holding element, piston guide element, and throttle elements are designed with predetermined connection interfaces that simplify the assembly process.

Inventive Principle:

Principle #10Preliminary action

3Adaptability or versatility

If multiple throttle elements are stacked in the valve cage, then throttling performance and fluid control are improved, but device complexity and manufacturing difficulty increase

Engineering Contradiction:

Improvethrottling performanceVSAvoidmanufacturing simplicity

Core Design Contradiction:

Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The throttling function is segmented into multiple independent throttle elements (throttle disks, throttle rings) that can be individually manufactured using standardized processes and then stacked in the valve cage. Each throttle element can be optimized for specific fluid types and flow requirements while maintaining manufacturing simplicity through modular design.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The throttle elements are designed with universal characteristics that allow them to be used in various configurations for different fluid applications. The standardized stacking arrangement enables the same basic component design to serve multiple throttling performance requirements across different valve configurations.

Inventive Principle:

Principle #6Universality (Multi-functionality)
