Modular Flow Diverter for Consistent Adhesive Application
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional adhesive application devices face issues with inconsistent adhesive application due to varying flow rates from nozzles with different numbers of outlets, leading to uneven adhesive distribution, and existing solutions require complex and costly components for individual metering.
Innovation Solution
A modular flow diverter plug with multiple channels is inserted into the applicator head, allowing each channel to be in fluid communication with the input conduit and output conduits, enabling controlled fluid distribution to nozzles based on their orifice count, ensuring consistent flow rates across all nozzles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If individual pumps are installed at each output conduit to meter adhesive flow, then flow rate control precision is improved, but device complexity increases and manufacturing cost increases
Solution Approach 1:
The patent combines multiple flow metering functions into a single flow diverter component that distributes adhesive to multiple nozzles. Instead of using separate pumps at each output conduit, the flow diverter integrates flow control for all nozzles into one unit, reducing device complexity while maintaining flow rate control precision through its internal channel geometry design
Solution Approach 2:
The flow diverter serves multiple functions simultaneously: it distributes adhesive to multiple nozzles, meters the flow rate to each nozzle, and provides a removable modular design for easy maintenance. This multi-functional component replaces what would otherwise require multiple individual pump units, reducing both complexity and cost
2Measurement precision
If individual pumps are installed at each output conduit to meter adhesive flow, then flow rate control precision is improved, but manufacturing cost increases
Solution Approach 1:
The patent combines multiple flow metering functions into a single flow diverter component that distributes adhesive to multiple nozzles. Instead of using separate pumps at each output conduit, the flow diverter integrates flow control for all nozzles into one unit, reducing manufacturing cost by eliminating the need for multiple expensive pump components
Solution Approach 2:
The flow diverter is designed as a removable, relatively simple component that can be easily manufactured and replaced if needed. This approach uses a simpler, more cost-effective component design compared to installing expensive pumps at each output conduit, while still achieving the required flow rate control precision
3Measurement precision
If individual pumps are installed at each output conduit to meter adhesive flow, then flow rate control precision is improved, but installation time increases
Solution Approach 1:
The patent combines multiple flow metering functions into a single flow diverter component that distributes adhesive to multiple nozzles. Instead of installing individual pumps at each output conduit, the flow diverter is installed as one unit, significantly reducing installation time while maintaining flow rate control precision through its internal channel design
4Ease of manufacture
If equal volume of adhesive is delivered to each nozzle, then manufacturing simplicity is improved, but adhesive application consistency deteriorates when nozzles have different outlet counts
Solution Approach 1:
The flow diverter incorporates channels with different cross-sectional areas or lengths tailored to each specific nozzle's requirements. This local customization of channel geometry ensures that each nozzle receives the appropriate adhesive flow rate based on its outlet count, achieving consistent adhesive application while maintaining the simplicity of a single integrated component
