Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing guide devices for ring spinning machines are difficult to thread, especially with service robots, and require significant effort to clean due to fibers getting stuck on the wire structures.
Innovation Solution
A guide device with a first and second guide element forming a closed contour guide area, allowing easy threading and cleaning, with the elements arranged parallel or one above the other, and connected via a perpendicular section, featuring an opening for fiber alignment and an arm for capturing the fiber structure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If known guide devices with spirally bent wires are used, then the guide device can control the fiber strand path, but threading the fiber strand becomes difficult especially with service robots
Solution Approach 1:
The guide device is divided into multiple separate guide elements (at least two) that can be individually positioned and adjusted. This segmentation allows the fiber strand to be threaded through each element sequentially, making the threading process more manageable and accessible to service robots compared to a single complex wire structure.
Solution Approach 2:
The guide elements are arranged in different spatial positions and orientations to form a guide area. By distributing guide elements across multiple dimensions rather than using a single planar wire structure, the invention creates a more accessible three-dimensional path for the fiber strand, facilitating easier threading operations.
2Ease of operation
If known guide devices with spirally bent wires are used, then the guide device can limit fiber strand movement, but cleaning becomes associated with increased effort due to fibers getting stuck
Solution Approach 1:
By separating the guide function into multiple discrete guide elements rather than a continuous wire structure, fibers that detach are less likely to become entangled and stuck. Each guide element presents a simpler surface for fibers to pass through, reducing the accumulation and sticking problems associated with spirally bent wires.
Solution Approach 2:
The guide elements are designed to be separable from each other, allowing individual elements to be removed and cleaned independently. This extraction capability enables maintenance personnel to access and clean each guide element separately, significantly reducing the effort required compared to cleaning a single complex wire structure where fibers become trapped in the spirals.
3Object-generated harmful factors
If guide elements are spaced apart to reduce fiber sticking, then cleaning becomes easier, but the guide area may allow unwanted fiber strand movement
Solution Approach 1:
Multiple guide elements create a segmented guide area that naturally contains the fiber strand through the collective arrangement of elements. The spacing between elements is optimized to prevent fiber sticking while the overall configuration maintains adequate containment, with the fiber strand following a defined path through the distributed elements.
Solution Approach 2:
The guide elements are positioned in three-dimensional space to create a guide area that contains the fiber strand through spatial arrangement. By utilizing vertical and horizontal positioning of multiple elements, the invention achieves effective containment without requiring the elements to be in direct contact or closely spaced, thus preventing fiber sticking while maintaining guide area integrity.
