Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual air gun or brush cleaning is used for busbars, then the cleaning process is simple, but the cleaning efficiency is low and cleaning effect is poor
Solution Approach 1:
The patent combines the cleaning function (rotating cleaning member) and dust suction function (dust suction member with suction port) into a single integrated dust removal mechanism. The cleaning member and dust suction member work simultaneously in one device, eliminating the need for separate manual cleaning operations and significantly improving cleaning efficiency while maintaining reasonable device complexity
Solution Approach 2:
The cleaning member is designed to rotate around an axis, providing dynamic cleaning action that improves contact with the busbar surface compared to static manual brushing. The rotation enables continuous cleaning motion that enhances both cleaning efficiency and effectiveness without requiring complex mechanical structures
2Productivity
If cleaning member contacts dust particles directly, then cleaning action is effective, but dust particles are stirred up and dispersed
Solution Approach 1:
The dust suction member acts as an intermediary between the cleaning member and the environment. As the cleaning member disturbs dust particles, the suction member immediately captures them through the suction port, preventing dispersion. The suction member mediates the interaction between cleaning action and dust particles, converting potential harm into controlled removal
Solution Approach 2:
The patent converts the harmful effect of dust particle stirring (which normally causes dispersion) into a benefit. The cleaning member's action of disturbing and lifting dust particles is immediately followed by suction capture, transforming the disturbance that would cause pollution into an effective dust removal mechanism where disturbed particles are efficiently collected
3Productivity
If dust suction port is close to cleaning member, then suction efficiency is high, but suction port area increases reducing suction force
Solution Approach 1:
The dust suction port is positioned at a specific local location on the dust suction member, optimized to be close to the cleaning member's path without direct contact. This local positioning provides sufficient proximity for high suction efficiency while maintaining an appropriately sized port area. The local quality of the suction port placement optimizes both suction force and efficiency
4Productivity
If single dust suction member is used, then device structure is simple, but suction coverage is insufficient
Solution Approach 1:
The dust suction member is positioned in a spatial arrangement that optimizes coverage. By strategically placing the suction member relative to the rotating cleaning member's path, the system achieves comprehensive dust capture across multiple dimensions of the busbar surface. This dimensional positioning provides enhanced coverage without requiring multiple suction members, maintaining structural simplicity

Function Achieved in This Case
The mechanism improves cleaning efficiency and stability, ensuring effective dust removal suitable for automatic production by rotating cleaning members and peripheral suction, reducing the risk of short circuits and enhancing the cleaning effect.
Implementation Method 1
dust particles adhering to the cleaning member, dust particles stirred up when the cleaning member is cleaning, or dust particles on the to-be-cleaned member are sucked away from the dust suction port through the dust suction member

AI summary
Disclosed is a dust removal mechanism, a dust removal device, a dust removal method, and a battery production system. The dust removal mechanism includes a mounting base, a cleaning member rotatably mounted on the base around an axis, and at least two dust suction members positioned on opposite sides of the cleaning member along a direction intersecting the axis. The dust suction members are located at the outer periphery of the cleaning member and each includes a dust suction port that does not contact the cleaning member. During cleaning, the cleaning member rotates to clean a target surface, and dust particles on the target surface, dust dislodged during cleaning, or dust adhering to the cleaning member are removed by suction through the ports. This configuration enables effective dust collection without direct contact between the suction ports and the cleaning component.
