Solution Overview

Problem

Existing fluid distributor units experience high pressure drops and turbulence due to sudden directional changes and sharp edges, leading to increased energy consumption and structural demands.

Innovation Solution

A fluid distributor unit with a flow conduit featuring at least three ports, including a releasable plug with a smooth flow directing surface shape that reduces turbulence by avoiding sharp edges, and a locking mechanism to secure the plug in place, allowing for smooth inner surfaces and reduced pressure drops.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of energy

If conventional fluid distributor units with sharp edges are used, then structural integrity is maintained, but pressure drop increases and energy consumption rises

Engineering Contradiction:
Improveenergy consumptionVSAvoidstructural complexity
Core Design Contradiction:
Loss of energyVSDevice complexity

Solution Approach 1:

The patent applies curvature by replacing sharp edges with rounded flow passage contours and curved transition surfaces. This eliminates sudden directional changes in fluid flow, reducing turbulence and pressure drop while maintaining structural integrity through smooth, continuous surfaces.

Inventive Principle:
Principle #14Spheroidality (Curvature)

Solution Approach 2:

The patent changes geometric parameters of the flow passages, specifically transitioning from sharp-edged to rounded contours with optimized curvature radii. This parameter modification reduces flow separation and turbulence intensity, thereby lowering energy losses without compromising mechanical strength.

Inventive Principle:
Principle #35Parameter changes

2Loss of energy

If smooth flow directing surfaces are added to reduce turbulence, then pressure drop decreases, but device complexity increases

Engineering Contradiction:
Improvepressure dropVSAvoidflow conduit complexity
Core Design Contradiction:
Loss of energyVSDevice complexity

Solution Approach 1:

The patent merges the flow directing function directly into the flow conduit structure itself, rather than adding separate components. The smooth surfaces are integrated as part of the conduit geometry, eliminating the need for additional attachments or modifications while achieving turbulence reduction.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The patent modifies the geometric parameters of the flow conduit to create smooth transition surfaces with optimized curvature. By changing the contour parameters from sharp to rounded edges, the design reduces pressure drop while keeping the overall structure simple and integrated.

Inventive Principle:
Principle #35Parameter changes

3Adaptability or versatility

If releasable plugs with locking elements are used to close openings, then adaptability improves, but device complexity increases

Engineering Contradiction:
Improveflow configuration adaptabilityVSAvoidplug and locking mechanism complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent segments the flow distributor into modular components: the main flow conduit and separate releasable plugs. This segmentation allows different plug configurations to be used with the same conduit, providing adaptability for various flow patterns while keeping each component relatively simple in design.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent introduces dynamic functionality through releasable plugs that can be inserted or removed to change flow configurations. The locking mechanism provides stable operation when closed, while the ability to release and reconfigure provides adaptability, creating a system that transitions between fixed and reconfigurable states.

Inventive Principle:
Principle #15Dynamics
