Electrode Rolling Layout With Repositionable Uncoated Pressing Unit
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrode production processes require the manufacturing of multiple rolling rolls to accommodate different battery cell specifications, leading to increased costs, storage difficulties, and prolonged process times due to the need for replacing entire rolling rolls.
Innovation Solution
An electrode producing device with a transport unit, coated-portion pressurizing unit, and an uncoated-portion pressurizing unit featuring a rotation roller with a changeable circumferential coupling portion, allowing the uncoated-portion pressurizing unit to be repositioned without replacing the entire unit.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple rolling rolls are manufactured to accommodate different battery cell specifications, then adaptability to various specifications is improved, but manufacturing cost and storage complexity increase
Solution Approach 1:
The rolling roll is divided into a main body and detachable protrusions. The protrusions can be removed and reattached at different positions, allowing the same rolling roll to accommodate different battery cell specifications without needing multiple complete rolling rolls. This segmentation enables flexibility while reducing the number of components that need to be stored.
Solution Approach 2:
The protrusions are designed to be movable and repositionable on the main body of the rolling roll. This dynamic configuration allows the rolling roll to adapt to different specifications by changing the position of protrusions rather than replacing the entire rolling roll, thereby reducing storage complexity while maintaining adaptability.
2Manufacturing precision
If entire rolling rolls are replaced to meet new specifications, then manufacturing precision is improved, but replacement time and process duration increase
Solution Approach 1:
By segmenting the rolling roll into a main body and detachable protrusions, only the protrusions need to be removed and repositioned when changing specifications, rather than replacing the entire rolling roll. This significantly reduces replacement time while maintaining manufacturing precision through proper reattachment of the protrusions.
Solution Approach 2:
The protrusions are designed with attachment mechanisms that allow for quick removal and repositioning. This preliminary design enables rapid reconfiguration of the rolling roll to meet new specifications without lengthy replacement procedures, reducing replacement time while ensuring precise positioning for manufacturing accuracy.
3Adaptability or versatility
If all types of rolling rolls are manufactured to meet specifications, then adaptability is improved, but manufacturing cost increases
Solution Approach 1:
The rolling roll is segmented into a standardized main body and interchangeable protrusions. This allows a single main body to serve multiple specifications by simply changing the protrusions, eliminating the need to manufacture multiple complete rolling rolls for different specifications, thereby reducing manufacturing cost while maintaining adaptability.
Solution Approach 2:
The main body of the rolling roll is designed as a universal component that can accommodate different protrusions for various specifications. This multi-functionality allows one main body to replace multiple specialized rolling rolls, reducing the overall manufacturing cost while maintaining the ability to meet different specifications.
