Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The handling of heavy electrode plate reels during the slitting process poses safety risks and efficiency challenges, including worker injury, reel damage, and reduced work efficiency due to manual handling and alignment issues.
Innovation Solution
An electrode plate reel holding apparatus with a hanger member, cradle, and separation-preventing part using retractable stoppers to securely hold and transport electrode plate reels, featuring a support shaft, rollers, and a stopper mechanism to prevent separation and facilitate automated movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If workers directly carry electrode plate reels using a transport cradle, then the reels can be transported, but worker injury risk increases due to the heavy weight (25-50 kg)
Solution Approach 1:
The electrode plate reel automatically performs the service of securing itself to the transport cradle through the stopper mechanism. When the reel is placed on the cradle, the stopper automatically protrudes from the through hole to engage with the reel, eliminating the need for manual intervention and reducing worker exposure to heavy objects.
Solution Approach 2:
The stopper acts as an intermediary element between the transport cradle and the electrode plate reel. It mediates the connection by protruding from the through hole to secure the reel, transferring the securing function from manual worker action to an automated mechanical component.
2Area of stationary object
If electrode plate reels are aligned at a narrow interval on the cradle, then space utilization improves, but reel collision damage increases
Solution Approach 1:
The stopper protrudes in advance to prevent reel separation before collision can occur. By securing the reel to the cradle through the stopper engagement, the system preemptively counteracts the potential harmful effect of collision that would result from narrow spacing.
3Ease of operation
If electrode plate reels are pulled out by manpower for mounting to notching equipment, then the reels can be transferred, but work efficiency decreases
Solution Approach 1:
The stopper is extracted or retracted from the through hole to allow the electrode plate reel to be easily removed from the cradle. This extraction action enables automated or assisted retrieval of the reel without requiring manual pulling, thereby improving work efficiency while maintaining transfer capability.
4Reliability
If a stopper protrudes from the support shaft to prevent reel separation, then reel security improves, but reel movement freedom decreases
Solution Approach 1:
The stopper transitions between two dynamic states: protruding from the through hole to secure the reel and retracting into the through hole to allow free movement. This dynamic adaptability resolves the contradiction by providing reel security when needed and movement freedom when needed, controlled by the system's operational requirements.

AI summary
Provided is an electrode plate reel holding apparatus of an electrode plate slitting machine for a secondary battery including a hanger member which is spaced apart from a bottom surface and on which at least one wound electrode plate reel is hung using a hollow support shaft, a cradle configured to support the hanger member, and a separation-preventing part including a stopper inserted into a through hole of the support shaft to be appealable and disappearable. The separation-preventing part may move the stopper into the through hole of the support shaft so that the electrode plate reel inserted into the support shaft moves without interference and move the stopper out of the through hole of the support shaft so that the electrode plate reel inserted into the support shaft is separated to the outside.
