Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual air gun or brush is used to clean 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 and dust suction function into a single integrated device. The cleaning member (brush or air gun) and dust suction member are positioned adjacent to each other and work simultaneously, allowing the cleaning device to both clean the busbar surface and suction away dust particles in one operation, thereby improving cleaning efficiency without requiring separate manual operations
Solution Approach 2:
The dust suction member acts as an intermediary that captures dust particles generated during cleaning. By positioning the dust suction member adjacent to the cleaning member, the system mediates between the cleaning action and the dust removal, preventing dust from redepositing and improving overall cleaning effect
2Productivity
If cleaning member rotates to clean busbar, then cleaning efficiency improves, but dust particles may spread or adhere to cleaning member
Solution Approach 1:
The patent extracts the dust particles from the cleaning zone by positioning the dust suction member adjacent to the cleaning member. The dust suction port is specifically positioned to capture dust particles as they are generated during rotation, preventing them from spreading to the surrounding environment or adhering to the cleaning member
Solution Approach 2:
The rotating cleaning member generates dust particles that would normally be harmful, but the patent converts this into a benefit by using the same rotational motion to generate airflow that directs dust particles toward the dust suction port. The dust generation during rotation is channeled into the suction system, turning a harmful effect into part of the dust removal process
3Productivity
If dust suction port is positioned close to cleaning member, then suction efficiency improves, but the suction port area increases reducing suction force
Solution Approach 1:
The patent applies local quality by positioning the dust suction port at a specific location adjacent to the cleaning member where dust particles are most concentrated. Rather than using a large suction port, the design focuses the suction capability at the precise location where dust generation occurs, maintaining high suction force while improving efficiency
4Productivity
If single dust suction member is used, then device structure is simple, but suction coverage is insufficient
Solution Approach 1:
The patent addresses insufficient suction coverage by positioning the dust suction member in a spatial arrangement adjacent to the rotating cleaning member. This dimensional positioning allows the suction port to capture dust particles throughout the rotation cycle, achieving comprehensive coverage without requiring multiple suction members

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
Implementation Method 2
the cleaning member of the dust removal mechanism may be rotated to clean the to-be-cleaned member

AI summary
The present application relates to 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 disposed on the mounting base around an axis, and at least two dust suction members disposed on the mounting base, located at an outer periphery of the cleaning member, and located on two opposite sides of the cleaning member in a direction intersecting with the axis, where each of the dust suction members is provided with a dust suction port, and the dust suction port is not in contact with the cleaning member. When there is a need to perform dust removal on a to-be-cleaned member, the cleaning member of the dust removal mechanism may be rotated to clean the to-be-cleaned member, and 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 at the outer periphery of the cleaning member, thus achieving dust suction.
