Adhesive Drum Connector Assembly With Latch Sealing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing connector assemblies for drums containing adhesive materials are difficult to connect and disconnect due to mechanical, threaded fittings, requiring tools and causing leakage issues.
Innovation Solution
A connector assembly featuring a drum fixture and hose fixture with a latch assembly that allows easy connection and rotation for fluid communication, including a seal member to prevent leakage, and manual intervention for disconnection, eliminating the need for special tools.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If mechanical threaded fittings are used to connect drums with downstream apparatus, then secure attachment and leakage prevention are achieved, but connection and disconnection become difficult and time-consuming requiring tools
Solution Approach 1:
The connector assembly is divided into separate components: a drum connector that attaches to the drum and a hose connector that attaches to the downstream apparatus. These segmented connectors use bayonet-style coupling with latch assemblies, allowing tool-free connection and disconnection while maintaining secure attachment and leakage prevention through seal members at each interface.
2Strength
If mechanical threaded fittings are used to connect drums with downstream apparatus, then secure attachment is achieved, but removal becomes difficult and time-consuming often requiring tools
Solution Approach 1:
The connector assembly incorporates dynamic latch assemblies that can be quickly engaged and disengaged. The latches transition between locked and unlocked states with simple manual manipulation, providing strong attachment during operation while enabling rapid removal when needed, eliminating the time-consuming process of unscrewing threaded fittings.
3Reliability
If a latch assembly is used to prevent rotation of the hose fixture, then secure connection is achieved, but manual intervention is required for removal
Solution Approach 1:
The latch assembly is designed to maintain automatic engagement during normal operation, preventing rotation and ensuring secure connection without requiring continuous manual attention. For removal, the system provides manual intervention through simple latch release mechanisms that are easier to operate than threaded fittings, allowing the user to quickly disengage the connection.
