Vacuum Chamber Sealing System with Segmented Heat Bars
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vacuum sealing systems for storage bags, particularly those used for foodstuffs, face issues such as liquids being sucked to the top due to pressure differentials, leading to incomplete sealing and spillage, and are often complex for amateur operators to use effectively.
Innovation Solution
A vacuum chamber sealing system with a transparent viewing panel, a support sleeve for easy bag loading, and a funnel for clean filling, allowing for controlled vacuum sealing and heat sealing of bags, which can be used independently or with a canister, and features a sealing mechanism that can be stopped or controlled during operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If a vacuum is applied to remove air from the bag, then air is removed from the bag, but liquids are sucked to the top of the bag interfering with sealing
Solution Approach 1:
The sealing mechanism is divided into separate functional zones: a first sealing bar for initial sealing and a second sealing bar for final sealing. This segmentation allows the sealing process to occur in stages, with the ability to control vacuum application between sealing operations, preventing liquid interference with the sealing process.
Solution Approach 2:
A preliminary seal is created by the first sealing bar before full vacuum is applied. This preliminary sealing action secures the bag structure and prevents liquid from moving to the sealing area during subsequent vacuum application, allowing reliable sealing to proceed.
2Reliability
If chamber based systems are used for vacuum sealing, then vacuum sealing is achieved, but the sealing process cannot be easily monitored or controlled by amateur operators
Solution Approach 1:
The sealing bars are made movable rather than fixed, allowing them to be positioned and adjusted by the operator. The first sealing bar can be moved to create an initial seal, then the second sealing bar can be positioned for final sealing. This dynamic adjustment capability gives amateur operators control over the sealing process while maintaining reliable sealing results.
Solution Approach 2:
The system provides visual feedback through transparent or translucent chamber walls, allowing operators to monitor the sealing process in real-time. This enables amateur operators to observe whether sealing is occurring correctly and make adjustments if needed, improving both control and reliability.
3Reliability
If the sealing mechanism is fixed and automatic, then sealing operation is reliable, but the device complexity increases for amateur operators
Solution Approach 1:
The sealing mechanism is segmented into multiple independent sealing bars that can be individually positioned and operated. This segmentation breaks down a complex automatic sealing system into simpler, manually controllable components, reducing the perceived complexity for amateur operators while maintaining sealing reliability through the multi-stage process.
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 system ensures a clean and efficient sealing process, preventing liquid spillage and allowing for easy operation, even by less experienced users, while supporting delicate materials like fruits and berries.
Implementation Method 1
A vacuum may be applied to remove extraneous air from within the bag
Implementation Method 2
A typical domestic sealing system includes two sealing bars. An open end of a heat-sealable bag is placed between the two sealing bars having heating wires or similar

AI summary
A lid for a vacuum sealing device may include a housing that supports a sealing station. The housing may define a sealing surface with a sealing perimeter that is able to seal against a canister body when the sealing surface is located on the canister body so that the sealing surface and the canister body together define a sealed volume. The sealing station is supported by the housing and extends from the housing. The sealing station is configured to heat seal an open bag, the sealing station being located within the sealing perimeter of the sealing surface such that when the lid is located onto the canister body, the sealing station is disposed within the sealed volume. The lid may have an internal pump for vacuum sealing operations or may receive a vacuum from an external source.
