Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual operation is used to open and close the cover, then the structure is simple, but the operation convenience deteriorates and time consumption increases
Solution Approach 1:
The patent replaces the manual mechanical operation system with an automated push-pull assembly that uses pneumatic or electric actuators to automatically open and close the sealing cover, eliminating the need for manual intervention and improving operational convenience
Solution Approach 2:
The push-pull assembly is designed to automatically execute the opening and closing actions of the sealing cover without requiring external manual control, making the system self-operating for this function and thereby improving ease of operation
2Productivity
If manual operation is used to open and close the cover, then the device structure remains simple, but productivity deteriorates due to time consumption
Solution Approach 1:
The automated push-pull assembly replaces manual mechanical operations with automated actuation mechanisms, significantly reducing the time required for each sealing cycle and thereby improving packaging productivity
Solution Approach 2:
The push-pull assembly is pre-configured to automatically execute the sealing cover operations at the appropriate moments in the packaging process, eliminating delays associated with manual intervention and improving overall productivity
3Ease of repair
If the sealing cover is fixedly connected, then the structural stability is improved, but the ease of maintenance deteriorates
Solution Approach 1:
The patent divides the sealing assembly into separable components (sealing base and sealing cover) that can be easily detached from each other, allowing the sealing cover to be removed for cleaning and maintenance while maintaining structural integrity during operation through the buckles and locking pins
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The device automates the vacuum sealing process, reducing manual labor and increasing operational convenience while allowing for easy disassembly and assembly for maintenance.
Implementation Method 1
a pneumatic assembly disposed in the sealing base and pushed the piston assembly to reciprocate within the piston cylinder. The pneumatic assembly includes a vacuum pump arranged within the sealing base, the first electromagnetic valve and the second electromagnetic valve. Both the first electromagnetic valve and the second electromagnetic valve are piped with the two piston cylinders so that negative pressure or positive pressure can be generated in the piston cylinder.
Implementation Method 2
a vacuum groove, a lower sealing strip is arranged surrounding the mouth of the vacuum groove. a sealing vacuum pump is disposed in the seat body, the sealing vacuum pump is connected with the vacuum groove by pipeline.
Implementation Method 3
a heating strip is arranged on the outside of the mouth of the vacuum groove; a upper sealing strip cooperated with the lower heating strip, so as to realize the sealing function.

AI summary
A vacuum sealing device includes a sealing base and a sealing cover arranged on the sealing base, the sealing base is also provided with a push-pull assembly for pushing and pulling the sealing cover; the push-pull assembly includes two piston cylinders disposed at both ends of the sealing base, a piston assembly disposed within the piston cylinder and pivoted to said sealing cover, and a pneumatic assembly disposed in the sealing base and pushed the piston assembly to reciprocate within the piston cylinder. The vacuum sealing device solves the trouble that the original mechanical structure needs to close and open the seal cover manually, thus realizing automatically vacuum sealing functions, it releases hands and greatly increases the convenience of operation.
