Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Spinning machines face challenges in maintaining uniform vacuum levels across a large number of work stations due to the length of the machines, leading to increased energy requirements and inefficiencies, especially with the need for high-performance fans to reduce pressure losses and turbulence in suction systems.
Innovation Solution
The integration of a suction device with two distinct effective areas, one with axial flow and one with radial flow, arranged either sequentially or partially in parallel, within the same impeller or as separate fans, to minimize turbulence and enhance efficiency, allowing for a higher suction power with the same energy input.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If a conventional radial fan is used to supply vacuum to multiple workstations, then the vacuum can be maintained, but energy consumption increases and pressure losses increase due to the length of the machine
Solution Approach 1:
The suction device is divided into two distinct effective areas: a first effective area with axial flow direction and a second effective area with radial flow direction. This segmentation allows each area to optimize its flow pattern, reducing overall pressure losses and energy consumption while maintaining sufficient suction capacity for multiple workstations.
Solution Approach 2:
Different regions of the suction device have different flow characteristics tailored to local requirements. The axial flow area handles certain airflow paths more efficiently, while the radial flow area optimizes other paths, creating locally optimized flow patterns that reduce overall system energy consumption.
2Productivity
If the number of workstations is increased to meet productivity demands, then machine length increases, but vacuum level becomes non-uniform and pressure losses increase
Solution Approach 1:
By segmenting the suction device into axial and radial flow areas, the system can better handle the increased airflow requirements from more workstations while maintaining more uniform vacuum levels throughout the machine length.
Solution Approach 2:
The invention introduces a dimensional change in flow pattern by combining axial and radial flow directions within the same suction device. This multi-dimensional approach to airflow allows the system to maintain effective vacuum distribution across longer machine lengths with more workstations.
3Power
If high-performance fans are used to reduce pressure losses, then suction capacity improves, but energy consumption increases
Solution Approach 1:
The suction device is segmented into two effective areas with different flow directions. This segmentation reduces pressure losses by optimizing flow paths, allowing the system to achieve sufficient suction capacity with lower energy consumption compared to conventional single-flow-pattern fans.
