Dispensing Unit Angled Boundary Surface for Adhesive Line Flexibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing adhesive delivery units require 90° screw connections for heating hoses, leading to temperature drops, pressure peaks, and increased installation complexity, limiting flexibility and productivity.
Innovation Solution
A delivery unit design with side surfaces arranged at an angle of 80-100°, featuring a boundary area with a blunt angle that allows for bilateral output directions of lines, enabling flexible installation and connection without the need for 90° screw connections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a 90° screw connection is used to connect the heated hose to the dispensing unit, then the line can be connected at a right angle to the dispensing unit orientation, but the adhesive temperature drops significantly and pressure peaks occur during heating
Solution Approach 1:
The boundary surface is designed with an asymmetric obtuse angle (80-100°) relative to the side surfaces, allowing the heated hose to connect at an angled direction rather than a perpendicular 90° connection. This asymmetric geometry enables the hose to exit in a direction that avoids sharp bends while maintaining installation flexibility, thereby preventing temperature drops and pressure peaks in the adhesive flow.
2Adaptability or versatility
If the dispensing unit is rotated by 90° to change the line outlet direction, then the line can be led in a different direction, but the entire dispensing unit must be repositioned which complicates installation
Solution Approach 1:
The connection geometry is segmented into two independent components: the side surfaces of the dispensing unit housing and the angled boundary surface of the distributor. This segmentation allows the boundary surface to provide directional flexibility for the heated hose connection without requiring rotation or repositioning of the entire dispensing unit, thereby simplifying installation while maintaining adaptability.
3Ease of manufacture
If the boundary surface is positioned parallel to the main axes of the dispensing unit, then the connection geometry is simple, but the line must lead away in fixed directions (rear or side) limiting installation options
Solution Approach 1:
The boundary surface is designed with a variable obtuse angle parameter (80-100°) relative to the side surfaces, deviating from the conventional parallel alignment. This parameter change enables the heated hose to connect at an optimized angle that provides flexibility for different installation orientations while maintaining a relatively simple connection geometry that is easy to manufacture.

Function Achieved in This Case
This design allows for flexible installation and operation of adhesive delivery units, reducing temperature fluctuations, pressure issues, and installation complexity, while enhancing productivity and adaptability to different line directions.
Implementation Method 1
The line that can be connected to the distributor and into which the molten adhesive can be dispensed from the distributor is in particular a heated hose, thus a heatable hose, so that the molten adhesive dispensed from the distributor does not cool down during conveyance through the line or the heated hose to an adhesive application device.
Implementation Method 2
a pump for conveying the adhesive through the distributor
