Innovation Solution
The coating device features a blocking assembly with a blocker that includes a cooperation and engagement portion forming an adjustable angle, extending into the gap between the scraping and coating rollers to block slurry spread, utilizing adjustable support structures to maintain the angle alignment with the gap size, ensuring effective coating and minimizing waste.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a blocking assembly with fixed angle is used, then slurry spread can be blocked, but coating quality cannot be maintained when gap changes
Solution Approach 1:
The blocker's angle portion is designed with adjustable geometry, allowing the angle between its two arms to be dynamically changed to match different gap sizes between rollers. This dynamic adaptability ensures the blocking function remains effective while maintaining coating quality across varying operating conditions.
Solution Approach 2:
The geometric parameters of the blocker, specifically the angle between its two arms, can be adjusted to correspond to different gap dimensions. This parameter change enables the blocking assembly to adapt to varying gap sizes while consistently preventing slurry spread and ensuring coating quality.
2Device complexity
If the blocker structure is simplified, then device complexity is reduced, but inability to adjust for gap changes reduces coating consistency
Solution Approach 1:
The blocker incorporates an adjustable angle mechanism that allows operators to modify the geometry according to gap size requirements. This dynamic adjustment capability maintains coating consistency across different operating conditions without requiring an overly complex multi-component system.
Solution Approach 2:
The blocker is designed as a multi-functional component that simultaneously provides slurry blocking and geometric adaptation to different gap sizes. This universal design approach maintains coating precision while avoiding the need for multiple separate adjustment mechanisms.
3Ease of manufacture
If the angle portion is fixed, then manufacturing is easier, but slurry spread cannot be prevented when gap varies
Solution Approach 1:
The blocker features an adjustable angle configuration that can be modified to match varying gap dimensions. This dynamic capability ensures slurry blocking effectiveness is maintained across different operating conditions while keeping the manufacturing process relatively simple through a single integrated component design.
Solution Approach 2:
The geometric parameter of the blocker's angle can be adjusted to correspond to different gap sizes, ensuring the blocking effectiveness is maintained. This parameter adjustability is achieved through a design that balances manufacturing simplicity with operational adaptability.
