Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Pneumatic transportation systems face issues with caking and scaling in bends and arcuate sections, leading to costly maintenance, potential contamination, and downtime due to material degradation and blockages, especially with crystalline substances like lactose monohydrate.
Innovation Solution
A diverter assembly with orthogonal input and output connections, featuring a collision wall and narrowing flow path to minimize material contact with the diverter body, preventing caking and scaling by using 'product-on-product' deflection and reducing friction, along with valve assemblies for flexible routing and sealing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional pneumatic transport pipes with bends and arcuate sections are used, then material can be transported between different locations, but caking and scaling occur in the bends leading to maintenance issues and contamination
Solution Approach 1:
The diverter assembly is divided into distinct functional sections: an input section, a collision section with collision walls, a flow path section, and output sections. This segmentation allows material to be redirected through controlled collision paths rather than following conventional bent pipe geometry, preventing caking while maintaining transport capability
Solution Approach 2:
Instead of bending the pipe to change direction, the invention inverts the approach by using collision walls to redirect material flow within a substantially straight pipe configuration. The material collides with collision walls and is deflected to output ports, reversing the conventional method of using arcuate bends for direction change
2Adaptability or versatility
If pipe bends are used for routing material, then flexible transportation paths are achieved, but friction and collision between particles and pipe walls cause material degradation and caking
Solution Approach 1:
Collision walls act as intermediaries between the input flow and output ports. These walls redirect material flow through controlled collision rather than through wall friction in bends, reducing particle-wall contact and degradation while maintaining routing flexibility through multiple output port configurations
Solution Approach 2:
The invention transitions from two-dimensional curved pipe bends to a three-dimensional internal flow redirection system using collision walls and flow path sections. This dimensional change allows material to be redirected in space without following conventional bent pipe geometry, reducing wall contact while achieving routing flexibility
3Ease of operation
If pipe bends and arcuate sections are used, then direction changes in material flow are achieved, but cleaning and maintenance become difficult and costly
Solution Approach 1:
The diverter assembly is designed with removable components including collision walls and flow path sections that can be easily accessed and cleaned. The modular design allows maintenance personnel to reach internal surfaces for cleaning without complex disassembly, making the system self-maintainable compared to conventional bent pipes
4Adaptability or versatility
If conventional bent pipes are used for material transport, then routing flexibility is achieved, but sterility is compromised due to accumulation zones in bends
Solution Approach 1:
The harmful accumulation zones characteristic of bent pipes are eliminated by extracting the bend geometry from the design. The diverter assembly uses collision walls and flow path sections to redirect material in a substantially straight pipe configuration, removing the zones where material would accumulate and compromise sterility
