Glue Valve Side-Opening Housing Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing glue valves with permanent magnets for closure require complex assembly and maintenance, and lack efficient contact construction for high-cycle operations.
Innovation Solution
The valve design features a side-opening housing allowing the coil and plug unit to be introduced laterally, with a prefabricated coil, coil core, and plug connected in one piece, and includes longitudinally running grooves on the valve tappet and permanent magnet for improved assembly and operation, enabling efficient power supply and glue feeding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the coil and plug are integrated as a separate unit introduced through a side opening, then the assembly process is simplified and manufacturing efficiency is improved, but the housing structure becomes more complex requiring side openings
Solution Approach 1:
The valve is divided into separate functional units: the coil-plug assembly is manufactured as a separate integrated unit from the housing, allowing independent production and simplified assembly through the side opening
Solution Approach 2:
The plug is accessed and connected through a side opening rather than the traditional top-down approach, utilizing the lateral dimension for assembly operations
2Productivity
If the valve tappet and permanent magnet have longitudinally running grooves for glue feeding, then glue application efficiency is improved, but the manufacturing complexity increases
Solution Approach 1:
The grooves are created only in specific localized areas of the valve tappet and permanent magnet where glue application is required, rather than throughout the entire components
Solution Approach 2:
The grooves are pre-formed during the manufacturing process of the valve tappet and permanent magnet, so that glue can be directly fed into the grooves during assembly without additional machining steps
3Volume of moving object
If the coil body partially encloses the valve tappet for compact design, then space utilization is improved, but the valve tappet movement and assembly become more difficult
Solution Approach 1:
Instead of assembling the valve tappet into the coil body from the top, the coil-plug assembly is introduced through the side opening, reversing the traditional assembly sequence and direction
Applied Scientific Principles

Function Achieved in This Case
This design simplifies assembly, ensures efficient operation, and allows for high-cycle performance with straightforward maintenance, enhancing contact construction and glue feeding efficiency.
Implementation Method 1
The electromagnet serves for moving the valve tappet into the open position counter to the closing force of the permanent magnets
Implementation Method 2
the closure element or the valve tappet is forced into the closed position by permanent magnets arranged within the valve housing
