Rotor Bow Tubular Guide Element Groove Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing rotor bows require significant force and time to fit and remove tubular wire guide tubes due to undersized grooves, leading to inefficiencies in processing elongate strand materials.
Innovation Solution
A rotor bow design featuring a continuous longitudinal groove with internal dimensions larger than the guide element, allowing easy insertion and removal without deformation, and a tubular guide element that can be 'clipped' into place, reducing wear and air resistance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a tubular wire guide tube is embedded in an undersized longitudinal groove, then the guide tube is securely held, but significant force and time are required for fitting and removal
Solution Approach 1:
Instead of making the groove smaller than the guide tube for secure fitting (traditional approach), the invention makes the groove larger than the guide tube. This inversion allows the guide tube to be easily inserted and removed without deformation, resolving the contradiction between secure holding and ease of assembly/disassembly
Solution Approach 2:
The invention changes the dimensional parameter relationship between the groove and guide tube from undersized (traditional) to oversized. This parameter change enables the guide tube to be freely inserted and removed while maintaining secure holding through the groove's structural support
2Reliability
If a tubular wire guide tube is pressed into an undersized groove, then the guide tube is firmly positioned, but considerable force is required for installation
Solution Approach 1:
The invention inverts the traditional approach by making the groove larger than the guide tube, eliminating the need for pressing or deformation. The guide tube is simply inserted into the oversized groove, reducing installation force to minimal levels while maintaining firm positioning through the groove's structural constraints
3Stability of the object's composition
If the groove is undersized to hold the guide tube, then the guide tube cannot move, but the guide element becomes difficult to remove
Solution Approach 1:
The invention makes the groove larger than the guide tube, which paradoxically provides both stability and ease of removal. The oversized groove allows the guide tube to be freely inserted and removed while maintaining stability through the groove's structural support and positioning
4Reliability
If a continuous notch is used to guide the strand material, then the guidance is continuous, but the rotor bow body is prone to wear
Solution Approach 1:
The invention segments the continuous guidance function by introducing a separate tubular guide tube within the groove. This segmentation allows the guide tube to bear the wear from strand material contact, protecting the rotor bow body from wear while maintaining continuous guidance through the tube's interior surface

AI summary
Flyer bow for a wire-braiding or cable-twisting machine, comprising a bow member that has a groove extending essentially along the entire longitudinal extension of the flyer bow in the longitudinal direction of the flyer bow. The flyer bow comprises a tubular guiding element, especially a coil spring, for guiding the elongate strand-type material that is placed in the groove without interruption, essentially along the entire longitudinal extension of the groove. The inner dimensions of the groove at any point along the longitudinal extension of the guiding element are greater than or equal to the outer dimensions of the guiding element at the same point. This makes it easy to remove and introduce, preferably pull out and insert, the guiding element from and into the groove.
