Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing false-twist texturing machines experience significant pressure loss in airflow due to the arrangement of blowers, leading to increased energy consumption, especially with longer duct lengths.
Innovation Solution
The design includes a blower connected to both ends of separate extending ducts aligned in the width direction, with intervening ducts and inclined ducts forming obtuse angles and a protruding portion to minimize pressure loss and turbulent flow, ensuring smooth airflow distribution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If a blower is provided for each duct arranged on both sides of the main frame, then the airflow can be generated in each duct, but significant pressure loss occurs in the airflow throughout the duct
Solution Approach 1:
The patent divides the airflow generation system into multiple blowers, each responsible for specific ducts. By segmenting the airflow paths and assigning dedicated blowers to each side's ducts, the system reduces the total duct length each blower must serve, thereby minimizing pressure loss while maintaining manageable device complexity through modular arrangement.
Solution Approach 2:
The patent arranges ducts and blowers in a three-dimensional configuration where ducts extend in the width direction and longitudinal direction, with blowers positioned at strategic locations. This spatial arrangement optimizes airflow paths by utilizing multiple dimensions, reducing the effective duct length and pressure loss without significantly increasing overall device complexity.
2Productivity
If the duct length in the longitudinal direction is increased, then the processing capacity is improved, but the pressure loss becomes more pronounced
Solution Approach 1:
The patent segments the long duct system into multiple shorter duct sections, each served by its own blower. This segmentation allows the system to maintain long overall processing capacity while each individual duct section remains short enough to minimize pressure loss, effectively decoupling productivity from energy loss.
Solution Approach 2:
The patent introduces intermediate blowers as mediator devices between the air source and the distant duct endpoints. These intermediate blowers act as additional driving forces that replenish airflow pressure in longer duct sections, enabling extended processing capacity without proportionally increasing pressure loss in any single duct segment.
3Quantity of substance
If the drive force of the blower is increased to generate sufficient airflow throughout the duct, then the airflow quantity is improved, but energy saving cannot be achieved
Solution Approach 1:
The patent divides the airflow generation task among multiple blowers rather than relying on a single high-power blower. Each blower operates at moderate drive force to serve its specific duct, collectively achieving the required total airflow quantity while consuming less total energy than a single high-power solution would require.
Solution Approach 2:
The patent applies drive force locally at each duct location through distributed blowers rather than using excessive drive force throughout the entire system. Each blower provides just enough drive force for its local duct, achieving sufficient airflow quantity at each location while minimizing overall energy consumption through localized, optimized driving.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This configuration reduces pressure loss, enhances energy efficiency, and prevents the scattering of foreign matter while maintaining uniform airflow generation.
Implementation Method 1
the blower generates negative pressure in each of the extending ducts
Implementation Method 2
the airflow from the first extending duct toward the blower and the airflow from the second extending duct toward the blower may collide in the intervening duct, and a turbulent flow may be generated. In this regard, according to the aspect of the present invention, the turbulent flow is suppressed as the airflows collide the protruding portion before colliding each other.
Implementation Method 3
When the blower generates a positive pressure in each extending duct, the protruding portion makes it possible to smoothly branch the airflow supplied from the blower to the intervening duct toward each extending duct. By suppressing the turbulent flow or smoothing the flow of the airflow in this way, the airflow generator can further suppress the pressure loss
