Chamber Bottom Suction Device for Vacuum Packaging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Chamber belt machines face issues with vacuum chamber evacuation due to long pipes or tubes connecting the suction device to a vacuum pump, leading to errors, increased costs, and a less attractive optical appearance.
Innovation Solution
Integrating a suction device at the bottom of the chamber belt machine, which also serves as a sealing device, eliminating the need for long pipes and tubes, and utilizing a single drive unit for both functions, thereby saving space and cost.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If long pipes or tubes are used to connect the suction device to the vacuum pump, then the vacuum chamber can be evacuated, but the system becomes more complex and susceptible to errors
Solution Approach 1:
The suction device is merged with the chamber bottom structure, integrating the vacuum evacuation function directly into the chamber assembly. This eliminates the need for separate long pipes and tubes, reducing system complexity and improving reliability by removing potential failure points in the piping system.
Solution Approach 2:
The suction function is extracted from a remote vacuum pump connection and integrated directly into the chamber bottom. This localizes the vacuum generation capability at the source, eliminating the intermediary piping system that causes complexity and reliability issues.
2Reliability
If long pipes or tubes are used to connect the suction device to the vacuum pump, then the vacuum chamber can be evacuated, but the cost increases
Solution Approach 1:
The suction device is combined with the chamber bottom as an integrated assembly, eliminating the need to manufacture and install separate long pipes and tubes. This reduces manufacturing costs by simplifying the bill of materials and assembly processes while maintaining vacuum production reliability.
3Reliability
If long pipes or tubes are used to connect the suction device to the vacuum pump, then the vacuum chamber can be evacuated, but the optical appearance deteriorates
Solution Approach 1:
The suction device is integrated into the chamber bottom structure, eliminating visible long pipes and tubes. This creates a cleaner, more compact appearance while maintaining the vacuum evacuation function, thus improving optical appearance without sacrificing reliability.
4Adaptability or versatility
If separate suction device and sealing device are used, then both functions can be performed, but space and cost increase
Solution Approach 1:
The suction device is designed to perform multiple functions: vacuum evacuation and sealing of the chamber bottom. This multi-functional design eliminates the need for separate sealing devices and multiple drive units, reducing space and cost while maintaining functional versatility through a single integrated mechanism.
Solution Approach 2:
The suction and sealing functions are merged into a single device located at the chamber bottom. This integration reduces the number of components and drive units required, simplifying the system while maintaining both vacuum evacuation and sealing capabilities.
