Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If two-component glue is used to achieve high-strength bonding, then bonding strength is improved, but the processing complexity increases due to the need for separate mixing and spraying procedures
Solution Approach 1:
The patent merges the mixing function and spraying function into a single integrated device. The mixing chamber is directly connected to the spraying nozzle, allowing two-component glue to be mixed and sprayed in one continuous operation without requiring separate mixing and spraying equipment, thus reducing processing complexity while maintaining high-strength bonding capability
2Device complexity
If static mixing is used to simplify the device structure, then device complexity is reduced, but productivity decreases due to procedure intervals between mixing and spraying
Solution Approach 1:
The patent implements continuous action by designing a system where glue components are continuously fed into the mixing chamber, mixed immediately, and continuously sprayed through the nozzle. This eliminates the procedure intervals inherent in static mixing methods, maintaining device simplicity while achieving continuous productive operation
Solution Approach 2:
The patent introduces dynamic mixing elements (such as static mixers or rotating mixing components) within the spraying device that actively mix the two-component glue during the spraying process itself. This dynamic approach allows mixing and spraying to occur simultaneously, eliminating idle time between operations while keeping the device structure relatively simple
3Stability of the object's composition
If mixing is performed before spraying to ensure proper mixing, then mixing uniformity is improved, but operation time increases due to sequential processing
Solution Approach 1:
The patent incorporates preliminary mixing chambers or pre-mixing sections where the two-component glue begins to mix before entering the main spraying nozzle. This preliminary action ensures initial uniformity is achieved, and the mixing process is completed during the spraying operation itself, thereby maintaining mixing uniformity while reducing total operation time compared to complete pre-mixing followed by separate spraying

AI summary
A jet device for mixing and dispensing glue. The jet device structurally includes glue feeding modules, a glue mixing module, a glue dispensing module, a cooling module, and a control module, where the at least two glue feeding modules are arranged, are in fluid communication with the glue mixing module through individual glue channels, and are capable of quantitatively conveying two-component glue at a constant pressure; a glue blending cavity and a spiral stirrer are arranged in the glue mixing module, two components of the glue converge in the glue blending cavity and are dynamically stirred and mixed by a stirring paddle, and stirring thrust pushes and guides the mixed glue to flow into the glue dispensing module; and the glue dispensing module drives, through a piezoelectric jet valve, a valve rod to move, to accurately jet the mixed glue.
