Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing stranding machines face issues with low processing speeds, high energy consumption, difficult spool replacement, and inability to adapt to varying quantities of cable strands, while maintaining stable unwinding conditions.
Innovation Solution
A spooling device with a rotatably mounted receiving device and disengaging bar, featuring a frame with axially movable frame parts and bearing points, allows for easy spool replacement and adaptation to different spool sizes, while ensuring stable unwinding and reverse twist stranding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single-sided holding device is used for the spool, then the device structure is simple, but the unwinding speed is limited and stability deteriorates
Solution Approach 1:
The holding device is divided into two separate bearing points (first bearing point and second bearing point) located at different positions along the frame. This segmentation allows the spool to be supported at multiple locations, improving stability and enabling higher unwinding speeds while maintaining reasonable structural complexity
Solution Approach 2:
The bearing points are arranged in the axial direction of the frame rather than only radially. This dimensional arrangement along the frame's length provides additional support points that enhance stability without significantly increasing structural complexity, allowing for higher operating speeds
2Stability of the object's composition
If the frame parts are fixed axially, then the structure is stable, but spool replacement becomes difficult and time-consuming
Solution Approach 1:
The frame parts are designed with axial movability, allowing them to move along the frame axis during spool replacement operations. This dynamic capability enables easy spool exchange while maintaining structural stability during normal operation, as the frame parts can be deliberately positioned to facilitate spool removal and installation
Solution Approach 2:
The frame parts can be pre-positioned axially to create clearance or access space before spool replacement is needed. This preliminary positioning action facilitates quick spool exchange without requiring complex disassembly procedures, reducing the time lost during spool replacement operations
3Device complexity
If the receiving device is fixed on the frame, then the structure is simple, but adaptability to different spool sizes and strand quantities is limited
Solution Approach 1:
The receiving device is mounted on the movable frame part, allowing it to move axially along with the frame part. This dynamic mounting enables the receiving device to adapt to different spool sizes and configurations while maintaining a relatively simple mounting structure, as the same movable connection mechanism handles various spool dimensions
Solution Approach 2:
The movable frame part with axial movement capability serves multiple functions: it provides structural support during operation, enables easy spool replacement, and allows adaptation to different spool sizes and strand quantities. This multi-functionality increases device versatility without proportionally increasing structural complexity
