Solution Overview

Problem

Conventional methods for installing a flow straightener in a fluid conveyance device require extensive cutting or flanged connections, which are time-consuming, costly, and can damage the system, while also necessitating regular maintenance due to potential chemical reactions and compromised structural integrity.

Innovation Solution

A flow straightener with a conical-shaped center and tapered vanes extending from it, allowing for installation through a smaller opening, with leading tapered edges for maneuvering and flat trailing edges for anchoring, reducing damage and simplifying the installation process.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If conventional installation methods (extensive cutting or flanged connections) are used to install a flow straightener, then the flow straightener can be installed in the fluid conveyance device, but the installation process is time-consuming, costly, and can damage the system

Engineering Contradiction:
Improveinstallation processVSAvoidinstallation time
Core Design Contradiction:
Ease of manufactureVSLoss of time

Solution Approach 1:

The flow straightener is divided into multiple modular sections that can be assembled together. Each section contains a specific number of vanes and can be independently installed, allowing the overall device to be installed in stages rather than requiring complete disassembly of the pipe system at once.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The flow straightener sections are designed to nest within each other or connect in a telescoping manner, where one section fits inside or alongside another. This nesting design allows the entire flow straightener assembly to be inserted through a relatively small opening in the pipe without requiring extensive cutting or flanged connections.

Inventive Principle:
Principle #7Nested doll (Nesting)

2Ease of manufacture

If conventional installation methods are used, then the flow straightener can be installed, but regular maintenance is required due to potential chemical reactions and compromised structural integrity

Engineering Contradiction:
Improveinstallation processVSAvoidstructural integrity
Core Design Contradiction:
Ease of manufactureVSReliability

Solution Approach 1:

The vanes are made from different materials depending on their specific function and exposure to the fluid. Critical vanes that contact the fluid directly are made from corrosion-resistant materials, while structural support elements may use different materials optimized for strength. This localized material selection maintains structural integrity while resisting chemical reactions.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The flow straightener employs composite construction where vanes are made from corrosion-resistant materials such as stainless steel or specialized polymers, while the connecting elements and support structures use high-strength materials. This composite approach ensures both chemical resistance and structural integrity without requiring sacrificial protection or frequent maintenance.

Inventive Principle:
Principle #40Composite materials

3Measurement precision

If a flow straightener is installed to straighten liquid flow and reduce turbulence, then accurate flow meter readings are achieved, but the installation may result in damage to the fluid conveyance device or the flow straightener

Engineering Contradiction:
Improveflow meter readingsVSAvoiddamage during installation
Core Design Contradiction:
Measurement precisionVSObject-affected harmful factors

Solution Approach 1:

The vanes are designed with curved, aerodynamic profiles rather than sharp edges or flat surfaces. The curved leading edges of the vanes smoothly guide the fluid flow, reducing turbulence and preventing cavitation or vortex formation that could damage the flow straightener or pipe walls during operation.

Inventive Principle:
Principle #14Spheroidality (Curvature)

Solution Approach 2:

The installation design includes protective features such as rounded corners, chamfered edges, and flexible sealing elements that prevent damage to the pipe during the installation process. The modular sections are designed to be inserted without requiring forceful hammering or excessive tightening, cushioning against potential damage before it can occur.

Inventive Principle:
Principle #11Beforehand cushioning (Prior cushioning)
