Fiber Guide With Inclined Surfaces For Tensioned Convergence
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional fiber guides face challenges in achieving convergence of a fiber bundle while applying tension evenly, leading to increased fiber loss due to difficulties in following the inner wall surface and maintaining tension throughout the bundle.
Innovation Solution
A fiber guide design with a main body featuring a fiber passage that includes inclined first and second surfaces, where the second surface is angled away from the first surface approaching the outlet, allowing for convergence of the fiber bundle while maintaining tension, with a minimum width portion at the outlet to facilitate smooth convergence and reduce fiber loss.

Engineering Contradiction Analysis
1Force
If the inlet is positioned away from the axis to increase tension on the fiber bundle, then the amount of tension applied increases, but it becomes difficult for the fiber bundle to follow the inner wall surface and converge
Solution Approach 1:
The fiber passage is divided into multiple sections with different surface characteristics: a first region with a first surface for initial guidance, and a second region with a second surface for convergence. This segmentation allows different portions of the fiber bundle to experience different guiding forces, enabling both tension application and convergence to be achieved simultaneously.
Solution Approach 2:
Different regions of the fiber passage are given different surface properties and orientations. The first surface is configured to apply tension while the second surface is specifically designed to guide convergence. This local differentiation of surface quality allows the passage to perform multiple functions in different locations, resolving the contradiction between tension application and convergence.
2Adaptability or versatility
If space is provided in the passage to apply twist to the fiber bundle, then twisting can be achieved, but it becomes difficult to cause the fiber bundle to follow the inner wall surface and converge
Solution Approach 1:
The fiber passage is segmented into distinct functional regions: a first region that accommodates twisting operations and a second region that focuses on convergence. This spatial segmentation allows twisting and convergence to occur in sequence without interfering with each other, enabling both functions to be performed effectively.
Solution Approach 2:
The fiber passage utilizes three-dimensional spatial arrangement with surfaces inclined at different angles relative to the axis. By configuring surfaces in different dimensional orientations, the passage can accommodate twisting motion in one dimensional aspect while simultaneously guiding convergence in another dimensional aspect, resolving the contradiction between these two functions.
3Manufacturing precision
If the second surface is inclined away from the first surface approaching the outlet, then convergence of the fiber bundle is achieved, but the area distribution in the outlet must be carefully controlled
Solution Approach 1:
The fiber passage employs asymmetric surface configuration where the second surface is inclined at a different angle than the first surface. This asymmetric design creates the necessary area distribution at the outlet to achieve convergence while maintaining a relatively simple geometric form. The unequal inclination angles naturally produce the required area differentiation without complex control mechanisms.
Solution Approach 2:
The inclination angles of the surfaces are carefully selected as specific parameters to achieve the desired convergence. By optimizing these angular parameters, the passage achieves effective convergence while maintaining simplicity in the overall design. The specific angle values serve as key parameters that control both convergence and area distribution simultaneously.

AI summary
A fiber guide (31) includes a main body (50) and a fiber passage (60). The fiber passage (60) has a first surface (61) disposed mostly in a first region (A1) and a second surface (62) disposed mostly in a second region (A2). The second surface (62) is inclined to be away from the first surface (61) as approaching the outlet (55). The first surface (61) is inclined by 5 degrees or less with respect to the axis (50L), and the second surface (62) is inclined by 5 degrees or more and 30 degrees or less with respect to the axis (50L). In the outlet (55), a first portion (55-1) included in the first region (A1) is smaller than a second portion (55-2) included in the second region (A2).
