Solution Overview

Problem

Conventional baffle designs in pipes require multiple installations to manage flow deviations, especially in deformed pipes, and are ineffective in improving existing flow deviations, leading to non-uniform fluid velocity and inefficiencies.

Innovation Solution

A baffle apparatus with adjustable baffle member spacing based on fluid velocity, where the first part of each baffle has an enlarged cross-section and the second part has a constant cross-section, with ends spaced according to the equation di=Df⁡(i)⁢∑i=1n⁢1f⁡(i), ensuring uniform fluid velocity across the baffle system.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If multiple baffles are installed in all regions where pipe deformation may occur, then flow deviation is minimized in deformed pipes, but device complexity and installation cost increase significantly

Engineering Contradiction:
Improveflow deviation controlVSAvoidnumber of baffles
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent applies local quality by varying the spacing between baffles according to the specific flow conditions at different locations. The distance between adjacent baffles is determined by the equation di=Df(i)∑i=1n1f(i), where the spacing is optimized based on local fluid velocity f(i) and cross-sectional area D. This means denser baffle arrangement in regions with higher flow deviation risk and larger spacing in stable regions, achieving effective flow control without uniformly installing baffles throughout the entire pipe system.

Inventive Principle:
Principle #3Local quality

2Ease of manufacture

If conventional baffle design is used, then installation is simple, but it cannot improve flow deviation that has already been generated in the pipe

Engineering Contradiction:
Improvebaffle installationVSAvoidflow deviation improvement
Core Design Contradiction:
Ease of manufactureVSReliability

Solution Approach 1:

The patent implements dynamics by making the baffle spacing adaptive rather than fixed. The distance between adjacent baffles is dynamically determined by the local fluid velocity and cross-sectional area according to the equation di=Df(i)∑i=1n1f(i). This dynamic spacing allows the baffle system to respond to varying flow conditions along the pipe, optimizing flow deviation correction at each location while maintaining a relatively simple baffle structure that can be manufactured and installed using conventional methods.

Inventive Principle:
Principle #15Dynamics

3Ease of operation

If uniform baffle spacing is used, then installation is straightforward, but fluid velocity remains non-uniform across the baffle system

Engineering Contradiction:
Improvebaffle spacingVSAvoidfluid velocity uniformity
Core Design Contradiction:
Ease of operationVSManufacturing precision

Solution Approach 1:

The patent applies parameter changes by varying the spacing parameter between baffles based on local flow conditions. Instead of using a fixed uniform spacing, the distance di between adjacent baffles is changed according to the local fluid velocity f(i) and cross-sectional area D using the equation di=Df(i)∑i=1n1f(i). This parameter optimization ensures that the baffle system achieves uniform fluid velocity distribution across different sections of the pipe, with denser spacing in regions requiring greater flow control and larger spacing where flow is already stable.

Inventive Principle:
Principle #35Parameter changes
