Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing gravure coating apparatuses are inflexible and require custom manufacturing when the number of bands or intervals between bands changes, leading to high manufacturing time and low productivity.
Innovation Solution
A gravure coating apparatus equipped with multiple position sensor modules and gravure roller modules, featuring a rotational force transmitting unit with gears, allows for adjustable positioning of gravure roller modules to accommodate various band numbers and intervals, enabling flexible coating configurations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a gravure coating apparatus performs gravure coating on each band one by one, then coating precision is maintained, but manufacturing time increases and productivity decreases
Solution Approach 1:
The patent combines multiple gravure coating operations into a single integrated apparatus with multiple gravure rollers arranged side by side. Each roller corresponds to a specific band position, allowing simultaneous coating of multiple bands in one pass through the apparatus, thereby maintaining precision while dramatically improving productivity
Solution Approach 2:
The coating apparatus is segmented into multiple independent gravure roller modules, each responsible for coating a specific band. This segmentation allows parallel processing of different bands while maintaining the precision of individual coating operations, resolving the contradiction between sequential precision and parallel productivity
2Manufacturing precision
If a gravure coating apparatus has a fixed number of rollers at fixed intervals, then coating precision for specific band configurations is achieved, but adaptability to different band numbers and intervals is lost
Solution Approach 1:
The patent employs movable and adjustable gravure roller modules that can be repositioned along the apparatus length. This dynamic configuration allows the same apparatus to adapt to different band numbers and intervals while maintaining coating precision, eliminating the need for custom-manufactured apparatus for different specifications
Solution Approach 2:
The gravure coating apparatus is designed as a universal platform with multiple adjustable rollers that can accommodate various band configurations. The same apparatus can be reconfigured for different numbers of bands and different intervals, providing multi-functionality and eliminating the need for dedicated apparatus for each specific configuration
