Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Textile machines used for producing composite yarns face challenges in mechanical strength and assembly complexity due to the high number of winding stations and superimposed take-up positions, which increases production costs and installation times.
Innovation Solution
A modular machine design featuring lateral side members, longitudinal beams, and an intermediate vertical structure facilitates easy assembly and alignment, allowing for a sturdy structure with multiple superimposed winding positions while reducing the machine's footprint and improving shaft alignment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If a high number of winding stations and superimposed take-up positions are arranged in a compact configuration, then the machine footprint is reduced, but the mechanical strength and structural stability deteriorate
Solution Approach 1:
The machine structure is divided into modular sections with standardized lateral side members and intermediate vertical structures. This segmentation allows the frame to be constructed from discrete, easily assembled components that maintain structural integrity while enabling compact arrangement of multiple winding stations and superimposed take-up positions.
Solution Approach 2:
The lateral side members and intermediate vertical structures serve multiple functions: they provide mechanical support, define the machine footprint, and enable precise alignment of shafts across different modules. This multi-functionality allows the same structural elements to simultaneously achieve compact configuration and maintain mechanical strength.
2Area of stationary object
If a high number of winding stations and superimposed take-up positions are arranged in a compact configuration, then the machine footprint is reduced, but the assembly complexity increases
Solution Approach 1:
The frame is segmented into standardized modular components (lateral side members, longitudinal beams, intermediate vertical structures) that can be manufactured separately and assembled systematically. This segmentation reduces assembly complexity by breaking down the complex task of constructing a compact multi-station machine into manageable, repetitive assembly steps using identical or similar components.
Solution Approach 2:
The lateral side members and intermediate vertical structures are designed with pre-defined connection points and alignment features that facilitate rapid assembly. The standardized geometry and connection interfaces are prepared in advance during component manufacturing, allowing for quick and accurate assembly of the complete machine structure without complex field adjustments.
3Strength
If conventional frame structures are used to support multiple superimposed winding positions, then the mechanical strength is maintained, but the assembly time and production costs increase
Solution Approach 1:
The conventional frame is replaced with segmented modular components that can be assembled rapidly using standardized connection methods. The lateral side members and intermediate vertical structures are designed as discrete units that can be manufactured using efficient processes and assembled in a systematic sequence, dramatically reducing installation time while maintaining the mechanical strength required to support multiple superimposed winding positions.
Solution Approach 2:
The structural parameters of the frame components are optimized to achieve the required mechanical strength with reduced material usage and simplified geometry. The lateral side members and intermediate vertical structures are designed with dimensions and connection features that enable rapid assembly, changing the parameters from conventional heavy-duty construction to optimized modular construction that maintains strength while reducing assembly time and cost.

AI summary
The module comprises a plurality of winding stations (1A) mutually aligned on at least one operating front. Each winding station comprises at least one feed zone (15) for feeding a plurality of yarns (F1; FC) toward a corresponding underlying plurality of mutually superimposed winding positions (17). Each winding position comprises a support (41) for a tube on which one of said yarns is wound to form a bobbin (B3), a motorized winding roller (43) in contact with the bobbin being wound, and a traversing device (45), to distribute the yarn in helical turns around the bobbin being formed. The module comprises lateral side members (111) substantially vertical and orthogonal to the direction of alignment of the winding stations. There are also provided longitudinal beams (125) parallel to the direction of alignment of the winding stations, which join the two lateral side members (111), and an intermediate vertical structure for facilitating assembly (135), arranged between the two lateral side members(111).
