Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The production efficiency of batteries is hindered by the roller adherence phenomenon during the diversion of electrode plates, leading to wrinkling and scrapping, which restricts the yield and efficiency of battery manufacturing.
Innovation Solution
A strip diverting mechanism utilizing a negative pressure unit and an air discharge unit, arranged opposite each other, provides a suction force and repulsive force respectively to divert the strip without contact, preventing wrinkling and improving yield by changing the running direction of the strip.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If a strip is attached to a peripheral surface of a diverting roller to divert the running direction, then the running direction of the strip can be changed, but the strip may be wrinkled due to a roller adherence phenomenon
Solution Approach 1:
The patent replaces the mechanical contact-based diverting roller system with a pneumatic field-based diverting mechanism. The negative pressure unit and air discharge unit create controlled airflow fields that exert forces on the strip to change its running direction without mechanical contact, thereby avoiding the roller adherence phenomenon that causes wrinkling.
Solution Approach 2:
The patent employs pneumatic principles by using a negative pressure unit (suction device) and an air discharge unit to generate controlled airflow. The negative pressure unit creates a suction force that pulls the strip, while the air discharge unit provides a repulsive force, together enabling non-contact diverting of the strip to change its running direction without causing surface damage.
2Ease of operation
If a diverting roller is used to change the running direction of the strip, then the diversion function is achieved, but the strip may contact the roller and become wrinkled leading to scrapping
Solution Approach 1:
The patent substitutes the mechanical diverting roller system with a pneumatic field system consisting of a negative pressure unit and an air discharge unit. This replacement eliminates mechanical contact between the diverting mechanism and the strip, preventing wrinkling and scrapping while maintaining the diverting function, thus improving strip yield and productivity.
Solution Approach 2:
The patent introduces air flow as an intermediary medium between the diverting mechanism and the strip. The negative pressure unit and air discharge unit manipulate the air flow to indirectly act on the strip, changing its running direction without direct contact. This intermediary approach prevents damage to the strip while achieving the desired diverting effect.
3Speed
If the strip is diverted using traditional contact methods, then the running direction can be changed, but the roller adherence phenomenon causes wrinkling and reduces production efficiency
Solution Approach 1:
The patent uses pneumatic principles with a negative pressure unit creating suction force and an air discharge unit providing repulsive force. This pneumatic system enables efficient non-contact diverting of the strip, changing its running direction quickly while maintaining strip integrity and preventing wrinkling, thus improving both diverting efficiency and reliability.
Solution Approach 2:
The patent replaces the mechanical contact-based diverting system with a pneumatic field-based system. This substitution eliminates the roller adherence phenomenon that causes wrinkling, maintaining strip integrity while achieving efficient diverting through controlled air flow forces from the negative pressure unit and air discharge unit.

AI summary
A strip diverting mechanism includes a negative pressure unit and an air discharge unit. The negative pressure unit and the air discharge unit are arranged opposite each other, and a gap through which a strip passes is formed between the negative pressure unit and the air discharge unit. The negative pressure unit is configured to provide a suction force to the strip and the air discharge unit is configured to provide a repulsive force to the strip, to prevent the strip from contacting the negative pressure unit and the air discharge unit. The negative pressure unit comprises two air channels located at two sides of the negative pressure unit and configured to discharge air to a direction away from the negative pressure unit, to generate a negative pressure area at a center of the negative pressure unit.
