Vacuum Packaging System With Heated Sealing Element
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vacuum packaging systems face safety and reliability issues due to the retention of exhaust pipes outside packaged containers and require complex structures and increased manufacturing costs due to the need for small-diameter exhaust pipes for efficient sealing.
Innovation Solution
A vacuum packaging system that uses a sealing element with a larger area than the exhaust through hole, made of glass or metal with low-melting glass powder, which is heated to form a seal within the packaging system, eliminating the need for an external exhaust pipe and allowing for batch packaging with improved safety and simplicity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If a small-diameter exhaust pipe is used for efficient sealing, then sealing speed is improved, but device complexity and manufacturing cost increase
Solution Approach 1:
The exhaust pipe is completely removed from the packaging structure. Instead of using a traditional exhaust pipe that extends outside the container, the invention uses an exhaust through hole directly formed in the container wall, eliminating the need for separate exhaust pipe components and their associated sealing complexity
Solution Approach 2:
The exhaust function is merged directly into the container structure by forming an exhaust through hole in the container wall. This integrates the exhaust pathway into the container itself, eliminating the need for separate exhaust pipe components and simplifying the overall structure
2Loss of time
If a small-diameter exhaust pipe is used for efficient sealing, then sealing time is reduced, but manufacturing cost increases
Solution Approach 1:
The exhaust pipe component is extracted and removed entirely. The exhaust through hole is formed directly in the container wall using standard container forming processes, eliminating the need for separate exhaust pipe manufacturing, assembly, and sealing operations
Solution Approach 2:
The exhaust through hole is formed during the container manufacturing process itself, before the packaging operation. This preliminary formation of the exhaust pathway eliminates the need for separate exhaust pipe installation and sealing steps, reducing both time and cost
3Ease of operation
If the exhaust pipe is retained outside the packaged container, then sealing operation is simplified, but safety and reliability deteriorate
Solution Approach 1:
The exhaust pathway is nested within the container structure itself rather than extending externally. The exhaust through hole is formed in the container wall, and the exhaust passage is contained within the container boundaries, eliminating external exhaust pipe components
Solution Approach 2:
The exhaust function is merged with the container structure, eliminating the boundary between container and exhaust pipe. This integration ensures that all exhaust components are contained within the packaged unit, improving safety and reliability

AI summary
A vacuum packaging system for packaging a vacuum apparatus includes a first accommodating room, a second container, a vacuum room, a first hatch, a second hatch, a delivery apparatus, a discharge device, and a heating apparatus. The delivery apparatus transports the vacuum apparatus from the first accommodating room to the vacuum room to the second accommodating room. The discharge device discharges a sealing element to seal an exhaust through hole of the vacuum apparatus. The heating apparatus is mounted on the inner wall of the vacuum room between the second hatch and the transport pipeline to heat and soften the sealing element.
