Viscous Media Dispensing Nozzle With Offset Application Modules
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices for applying viscous media, such as adhesives, to a moving substrate are limited in flexibility and minimum application width due to the arrangement of application modules in a single row, restricting the variety of application patterns and requiring dispensing openings to match the width of the modules.
Innovation Solution
The device features application modules arranged in multiple offset rows with varying dispensing opening widths and angles, allowing for strip-shaped and flat applications, with optional assembly gaps and interchangeable slot nozzles to enhance pattern flexibility and uniformity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If application modules are arranged in a single row with dispensing openings matching module width, then the device structure is simple, but the minimum application width is limited and pattern flexibility is restricted
Solution Approach 1:
The patent transitions from a single-row arrangement to a multi-row arrangement of application modules, adding a longitudinal dimension to the layout. This dimensional change allows dispensing openings to be positioned at different longitudinal locations, enabling varied application patterns and reducing minimum application width without significantly increasing overall device complexity.
2Ease of manufacture
If dispensing opening width corresponds to application module width, then the structure is straightforward, but the minimum application width is limited by the overall width of the application valve
Solution Approach 1:
The patent divides the single application valve into multiple application modules arranged in rows. Each module has its own dispensing opening and can be independently controlled. This segmentation allows the minimum application width to be determined by individual module dimensions rather than the overall valve width, enabling narrower applications while maintaining manufacturing simplicity.
3Adaptability or versatility
If multiple rows of application modules are arranged offset relative to each other, then application pattern flexibility and minimum width reduction are achieved, but device complexity increases
Solution Approach 1:
The patent utilizes the longitudinal dimension by arranging application modules in multiple rows offset along the substrate travel direction. This allows the system to achieve varied application patterns and reduced minimum widths by positioning dispensing openings at different longitudinal locations, managing complexity through systematic spatial organization rather than random arrangement.
