Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing take-off equipment using rotating arms struggles to maintain proper orientation of strands during transfer from active to standby packages, disrupting continuous unwinding and feeding to downstream equipment.
Innovation Solution
A splicing apparatus with collapsible splice triggers and a splice wrap housing ensures proper routing of strands, maintaining orientation with respect to packages and downstream equipment, utilizing magnetic forces to hold arms in position and collapsing triggers to manage strand tension.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If rotating arms are used to unwind packages, then continuous feeding to downstream equipment is achieved, but proper orientation of strands during transfer from active to standby packages becomes difficult to maintain
Solution Approach 1:
A splice trigger mechanism acts as an intermediary device between the rotating arm and the strand. The trigger includes a trigger arm that engages with the strand and a trigger blade that collapses to guide the strand through a housing opening, ensuring proper orientation during the critical transfer moment from active to standby package without interrupting continuous feeding
Solution Approach 2:
The splice trigger is pre-positioned and pre-configured in the housing before the strand transfer occurs. The trigger arm is initially engaged with the strand, and the housing opening is prepared in advance, so that when the transfer moment arrives, the orientation control is already in place, eliminating delays and maintaining both continuity and precision
2Productivity
If package replacement is performed during unwinding, then continuous operation without stopping downstream equipment is achieved, but strand routing and orientation control become complex
Solution Approach 1:
The splice trigger mechanism combines multiple functions into a single integrated device: it guides the strand, maintains orientation, controls tension during transfer, and interfaces with the rotating arm. This merging of functions into one compact housing reduces the overall complexity compared to having separate devices for each function while enabling uninterrupted package replacement
3Manufacturing precision
If strand tension is managed during package transfer, then proper strand routing is maintained, but additional mechanisms are required to control tension dynamically
Solution Approach 1:
The splice trigger blade is designed to collapse dynamically in response to strand tension forces. When tension increases during strand transfer, the trigger blade automatically collapses to guide the strand through the housing opening, and when tension decreases, it returns to its initial position. This dynamic response eliminates the need for external tension control mechanisms while maintaining precise strand routing
