Transformable Packing Body for Linear Material Draw-Out
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing draw-out device for linear materials requires a rotatable spin body and arms, leading to a complicated structure and increased size, which complicates the draw-out process.
Innovation Solution
A packing unit with a transformable packing body that houses the linear material, allowing the outlet for drawing out the material to be positioned higher than the uppermost part of the packing body in its first configuration, eliminating the need for arms or complex structures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a rotatable spin body and arms are used to draw out linear material, then the linear material can be prevented from tangling and kinking, but the structure becomes complicated and the size increases
Solution Approach 1:
The invention extracts and eliminates the complex spin body and arms from the draw-out device, replacing them with a simple reel that rotates about the winding center. This removal of unnecessary components directly resolves the contradiction by maintaining draw-out functionality while dramatically simplifying the structure.
Solution Approach 2:
Instead of using arms extending from a spin body to manage the linear material, the invention inverts the approach by using a reel that rotates about the winding center itself, with the linear material wound directly on it. This inversion eliminates the need for separate arms and spin body structures.
2Reliability
If a rotatable spin body and arms are used to draw out linear material, then the linear material can be prevented from tangling and kinking, but the device size increases
Solution Approach 1:
The invention extracts and eliminates the complex spin body and arms from the draw-out device, replacing them with a simple reel that rotates about the winding center. This removal of unnecessary components directly resolves the contradiction by maintaining draw-out functionality while dramatically simplifying the structure.
Solution Approach 2:
The invention merges the functions of the spin body and arms into a single integrated reel structure that rotates about the winding center. This consolidation eliminates the need for separate components, reducing overall device volume while maintaining the ability to prevent tangling and kinking.
3Reliability
If the outlet is positioned at the uppermost part of the packing body, then the draw-out property is improved, but the outlet cannot be positioned high enough for optimal drawing out
Solution Approach 1:
The invention makes the outlet position dynamic by allowing the packing body to rotate about the winding center. As the packing body rotates, the outlet naturally rises to a higher position during the drawing out process, enabling optimal outlet height without requiring a permanently tall structure.
Solution Approach 2:
The invention introduces rotational motion as a new dimension to the packing body, allowing the outlet to achieve greater height through rotation rather than requiring increased vertical dimension in the static structure. This dimensional change enables the outlet to be positioned higher during operation.

AI summary
To improve the draw-out property of a linear material without the need to prepare such structures as arms, a packing unit according to the present disclosure includes a linear material, and a packing body configured to house the linear material. The packing body is transformable between a first configuration for packing the linear material, and a second configuration for drawing out the linear material. In the second configuration, an outlet through which the linear material is drawn out from the packing body is located in a higher position than an uppermost part of the packing body in the first configuration.
