Straight Core Yarn Feeding Path Prevents Oil Accumulation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional core yarn supplying devices face issues with oil solution accumulation on the core yarn, which affects the feeding path and requires complex arrangements to prevent interference with other machine components.
Innovation Solution
A core yarn supplying unit with a straight feeding path and a tension applying section, where the feeding path is arranged on a straight line connecting the inlet and outlet regions, preventing oil solution accumulation and allowing for easier maintenance, and the tension applying section and feeding section can be positioned independently to avoid interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a bent pipe is used to control the feeding direction of the core yarn, then the core yarn can be guided to the correct position, but oil solution accumulates in the pipe
Solution Approach 1:
Instead of using a bent pipe to guide the core yarn, the invention inverts the approach by using a straight pipe and controlling the yarn direction through the orientation of the pipe itself. The core yarn feeding section is configured with a straight through-hole that allows the yarn to pass in a straight line, preventing oil solution accumulation while still achieving proper yarn guidance through alternative means.
Solution Approach 2:
The invention extracts the bending function from the pipe structure itself and separates it into a different component or mechanism. The pipe is reduced to a simple straight conduit for yarn passage, while the feeding direction control is achieved through the positioning and orientation of the entire feeding section rather than through pipe geometry.
2Reliability
If a complex arrangement is used to prevent interference with other machine components, then component interference is avoided, but the degree of freedom in arranging tension and feeding sections is reduced
Solution Approach 1:
The invention segments the core yarn supply system into distinct functional modules: a tension applying section and a core yarn feeding section. Each section can be independently positioned and adjusted, allowing flexible arrangement to avoid interference with other machine components while maintaining reliable operation. The modular design enables separate optimization of each function.
Solution Approach 2:
The invention resolves spatial interference issues by utilizing multiple dimensions for component arrangement. The tension applying section and feeding section are positioned at different locations and orientations in three-dimensional space, allowing both sections to function independently without interference while maintaining arrangement flexibility through vertical and horizontal positioning options.
