Winding Core Notch for Easy Medium Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing winding apparatuses face difficulties in removing a continuous medium from a winding core section without a paper tube, making it challenging to detach the wound medium.
Innovation Solution
A winding apparatus with a notched portion on the winding core unit and a detachable notch complementing unit, allowing for easy removal of the wound medium by pivoting the notch complementing section between a contact and separated position.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a paper tube is used to wind the continuous medium, then the continuous medium can be easily removed, but the device complexity increases
Solution Approach 1:
The winding core unit is segmented into a main body and a detachable notch complementing unit. The notch complementing unit can be removed to create access points for easily detaching the continuous medium, while the main body maintains its structural integrity during winding operations.
Solution Approach 2:
The notch complementing unit provides localized structural modification at specific positions on the winding core. By adding notches only where needed for medium removal, the overall structure remains simple while gaining the functionality of easy detachment.
2Stability of the object's composition
If the winding core section has a complete circular shape, then the winding stability is improved, but the ease of removing the wound medium deteriorates
Solution Approach 1:
The winding core structure is made dynamic through the detachable notch complementing unit. During winding, the unit is attached to maintain circular stability; after winding, it can be detached to create notches that facilitate easy medium removal. This dynamic reconfiguration allows the structure to adapt to different operational phases.
Solution Approach 2:
The notch complementing unit is pre-positioned on the winding core before winding begins. This preliminary attachment ensures the circular shape is maintained during the winding process, and the unit remains in place until the winding is complete and removal is needed.
3Ease of operation
If the notch complementing unit is detachably inserted, then the ease of removing the wound medium is improved, but the device complexity increases
Solution Approach 1:
The notch complementing unit is designed as a separate, detachable component that can be easily attached to and removed from the winding core body. This segmentation allows the unit to be independently manufactured and positioned only when needed, simplifying the overall system while providing the required functionality.
Solution Approach 2:
The notch complementing unit serves multiple functions: it maintains the circular shape during winding, provides structural support, and when detached, creates notches for medium removal. This multi-functionality reduces the need for separate components, thereby minimizing overall device complexity.

AI summary
A winding apparatus includes a winding core unit onto which a continuous medium is to be wound, the winding core unit having a notched portion having a shape in which a part of the winding core unit in a circumferential direction is cut out as viewed in an extending direction of the winding core unit, and a notch complementing unit to be detacheably inserted into the notched portion from one end portion side in the extending direction of the winding core unit, the notch complementing unit being configured to complement the notched portion.
