Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Impurities such as foam particles and dust adsorb onto the surfaces of battery cells during the assembly process, leading to reduced battery quality due to their incorporation into the battery.
Innovation Solution
A cleaning apparatus with a movable cleaning member driven by a mechanism to perform a frictional motion relative to the cell surfaces, accompanied by an ion air knife to eliminate static electricity, and a dust collection system to remove impurities, ensuring thorough cleaning and prevention of impurity absorption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a cleaning member performs frictional motion relative to the cell surface, then impurities are removed from the cell surface, but the cleaning member may generate static electricity that causes impurities to adsorb onto the cell surface
Solution Approach 1:
The patent extracts and addresses the harmful static electricity effect separately from the cleaning function. An ion air knife is introduced to specifically counteract the static electricity generated by the cleaning member, while the cleaning member itself focuses solely on the mechanical removal of impurities through frictional motion.
Solution Approach 2:
The ion air knife acts as an intermediary device between the cleaning member and the cell surface. It generates ionized air that neutralizes static electricity on the cell surface, preventing impurity adsorption without interfering with the mechanical cleaning action of the cleaning member.
2Ease of operation
If the cleaning member is disposed to exceed the workbench surface, then it can easily contact and clean the cell surface, but the structure becomes more complex
Solution Approach 1:
The cleaning member is designed with movable characteristics, allowing it to dynamically adjust its position and contact with the cell surface. This dynamic design enables the cleaning member to exceed the workbench surface when needed for effective cleaning while maintaining structural flexibility and avoiding excessive complexity.
