Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If traditional flow regulators are used with separate control elements, then temperature-dependent flow control can be achieved, but the device becomes complex and requires multiple parts for assembly

Engineering Contradiction:
Improvetemperature-dependent flow controlVSAvoidnumber of parts
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent combines the cover element and the temperature-sensitive control element into a single integrated component. The control element is formed as one piece with the cover element, eliminating the need for separate control elements and reducing assembly complexity while maintaining temperature-dependent flow control functionality.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The cover element serves multiple functions: it covers the flow regulator openings, provides the temperature-sensitive control functionality through the integrated control element, and acts as the structural component for flow regulation. This multi-functionality reduces the total number of parts needed in the device.

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

2Adaptability or versatility

If additional adjustable elements are added to achieve temperature-dependent behavior, then functional control is improved, but the dimensions of the sanitary part increase

Engineering Contradiction:
Improvetemperature-dependent functional behaviorVSAvoiddimensions of sanitary part
Core Design Contradiction:
Adaptability or versatilityVSVolume of moving object

Solution Approach 1:

By merging the temperature-sensitive control element directly into the cover element, the patent eliminates the need for additional adjustable elements that would increase the volume. The control element is formed as one piece with the cover element, achieving compact dimensions while maintaining full temperature-dependent functionality.

Inventive Principle:
Principle #5Merging (Combining)

3Manufacturing precision

If multiple separate components are used for flow control, then precise temperature-sensitive control can be achieved, but assembly steps increase and production becomes more complex

Engineering Contradiction:
Improvetemperature-sensitive control precisionVSAvoidassembly steps
Core Design Contradiction:
Manufacturing precisionVSEase of manufacture

Solution Approach 1:

The control element is formed as one piece with the cover element through a single manufacturing process, eliminating the need for separate assembly steps. This integration maintains precise temperature-sensitive control functionality while significantly simplifying production and assembly.

Inventive Principle:
Principle #5Merging (Combining)
