Dual Pattern Shim Assembly for Hot Melt Adhesive Dispensing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current hot melt adhesive dispensing systems struggle to deposit multiple adhesive materials with different thickness dimensions or patterns in an overlying or overlapping manner during a single pass, often resulting in interference or complexity with dual applicators and prolonged production times.
Innovation Solution
A dual pattern shim assembly with paired pattern shims and a separator shim, integrated with a hot melt adhesive contact die applicator, allows for simultaneous deposition of multiple adhesive materials with predetermined patterns and thicknesses by utilizing distinct supply paths and fluid channels, enabling crisp and clean deposition patterns.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If two different contact die applicators are used to deposit different adhesive materials, then multiple adhesive patterns can be deposited, but the first adhesive material is wiped off the substrate by the second applicator
Solution Approach 1:
The patent combines multiple adhesive deposition functions into a single contact die applicator head by integrating multiple shims with different adhesive supply paths. This allows simultaneous deposition of multiple adhesive patterns without interference from separate applicators, resolving the wiping problem while maintaining pattern integrity.
Solution Approach 2:
The contact die applicator is segmented into multiple independent shims, each responsible for depositing a specific adhesive pattern. Each shim has its own adhesive supply path and can be independently controlled, allowing precise deposition without interference from other adhesives.
2Productivity
If a contact die applicator with multiple adhesives is used, then multiple deposition patterns can be achieved in a single pass, but the system complexity increases with multiple pneumatic and hydraulic systems
Solution Approach 1:
Multiple adhesive supply paths are integrated into a single contact die applicator head, eliminating the need for multiple separate applicators and their associated pneumatic and hydraulic systems. This reduces overall system complexity while maintaining the capability to deposit multiple adhesive patterns simultaneously.
Solution Approach 2:
The contact die applicator head is designed as a universal device that can handle multiple adhesive materials through integrated shims and supply paths. This multi-functional design eliminates the need for separate specialized equipment for each adhesive type.
3Adaptability or versatility
If multiple separate applicators are used for different adhesive materials, then different deposition procedures can be performed, but the assembly line becomes more complex and production time increases
Solution Approach 1:
Multiple adhesive deposition functions are merged into a single applicator head, enabling simultaneous deposition of multiple adhesive patterns in one pass. This eliminates the need for sequential operations with separate applicators, reducing production time while maintaining procedural flexibility.

AI summary
A dual pattern shim assembly, for use in conjunction with hot melt adhesive dispensing systems, permits various different overlapping or overlying deposition or application patterns, having different length dimensions, different width dimensions, different coating thicknesses, and different longitudinal positional locations or dispositions with respect to each other, to be achieved during a single pass of the underlying substrate with respect to the hot melt adhesive contact die applicator or head. In this manner, different or multiple adhesive deposition or application procedures are able to effectively be accomplished simultaneously so as to effectively simplify and shorten the overall assembly lines and production times required for the fabrication or manufacture of various different particular products.
