Angled Piece Insert With Flow Guide for Lower Pressure Drop
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Angled pieces in fluid line systems produce significant pressure drops due to vortices created by sharp edges, which are a result of the manufacturing process, leading to inefficiencies in fluid flow.
Innovation Solution
An insert piece with a mounting having a recess is designed to be inserted into the channel section of an angled piece, reducing the flow cross-section and minimizing pressure drops by guiding fluid flow with a curved surface, and incorporating a spring element to absorb deformations and protect the guide element from mechanical stress.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a sharp edge is produced between the legs of the angled piece during injection molding, then the mold core can be easily withdrawn, but significant pressure drops occur due to vortex formation when fluid flows over the sharp edge
Solution Approach 1:
The mounting is divided into first and second sections with a recess between them, allowing the guide element to be positioned in the opening without requiring a complex integrated structure. This segmentation enables easy manufacture while maintaining flow guidance functionality.
Solution Approach 2:
A guide element is introduced as an intermediary component between the fluid flow and the sharp edge of the channel section. This guide element smoothly directs the fluid over the edge, eliminating vortex formation and pressure drops while keeping the mold core withdrawal process simple.
2Loss of energy
If a guide element is added to reduce pressure drop, then fluid flow efficiency is improved, but the device complexity increases
Solution Approach 1:
The mounting structure is segmented into first and second sections with a recess, allowing the guide element to be simply positioned in the opening rather than requiring a complex integrated design. This maintains low device complexity while achieving flow guidance.
Solution Approach 2:
The mounting structure itself provides the guidance function through its recess and opening configuration, with the guide element being a simple component that fits into the opening. The structure serves its own guidance purpose without requiring additional complex mechanisms.
3Ease of operation
If the opening in the mounting is large to accommodate the guide element, then the guide element can be properly positioned, but the flow cross section decreases
Solution Approach 1:
The recess is positioned at the inner edge of the angled piece, utilizing the edge region rather than the central flow area. This dimensional placement allows the opening to be sufficiently large for guide element positioning while minimizing impact on the main flow cross section.
Solution Approach 2:
The recess is located specifically at the inner edge region where it is needed for guide element positioning, rather than uniformly distributing the opening throughout the mounting. This local placement maintains flow cross section in the critical central areas while providing adequate space for the guide element at the edge.
