Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing modular creels are large and lack devices to control thread tension and speed, making it difficult to maintain constant thread supply to textile machines, which is crucial for defect-free production, and do not facilitate easy spool replacement or support multiple threads with varying speeds and tensions.
Innovation Solution
A modular creel element with a compact design that allows easy coupling, includes a device for constant tension and speed control, and features rotating arms for easy spool replacement, along with a sensor system to signal when spools need to be loaded, enabling independent control of each thread and flexible production settings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If modular creels are designed with fixed arms supporting spools at high heights, then the structural stability is improved, but the ease of spool replacement deteriorates
Solution Approach 1:
The arms supporting the spools are made rotatable about vertical axes rather than being fixed. This allows the arms to be dynamically repositioned to facilitate spool replacement while maintaining structural stability during operation. The dynamic capability enables operators to easily access and replace spools without compromising the overall structural integrity of the creel.
2Device complexity
If modular creels are designed with simple support structures, then the device complexity is reduced, but the ability to control thread tension and speed deteriorates
Solution Approach 1:
The creel is divided into independent modular elements, each capable of supporting and controlling one or more threads. Each module includes its own spool support, thread guide, and tension/speed control device. This segmentation allows the system to maintain simple individual components while achieving sophisticated thread control capabilities through the combination of multiple modules.
Solution Approach 2:
Each modular element is designed to be universal, capable of supporting spools at multiple positions and controlling thread parameters. The modules can be coupled together in various configurations to create creels that handle multiple threads with different tension and speed requirements, making the system versatile without increasing individual component complexity.
3Manufacturing precision
If modular creels are designed with fixed configurations, then the manufacturing precision is improved, but the adaptability to different production requirements deteriorates
Solution Approach 1:
The creel system is segmented into standardized modular elements that can be manufactured with high precision using identical processes. Each module is a precision-manufactured unit that can be coupled with others to create creels of various sizes and configurations. This allows maintaining manufacturing precision through standardized production while achieving adaptability through modular assembly.
Solution Approach 2:
The modular elements incorporate movable and adjustable components such as rotatable arms and adjustable thread guides. These dynamic features allow the same precision-manufactured module to be configured for different production requirements, enabling adaptability without sacrificing the manufacturing precision achieved through standardized production.
4Area of stationary object
If multiple spools are arranged on facing posts with threads fed in opposite directions, then the space utilization is improved, but the ease of inserting control devices deteriorates
Solution Approach 1:
The creel is segmented into modular elements where each module handles one or more threads independently. Control devices for thread tension and speed are integrated into each module, allowing them to be positioned without interference from adjacent threads fed in opposite directions. This segmentation enables effective space utilization while maintaining ease of installing and operating control devices.
