Vacuum Sealer with Pressure Sensor for Liquid Bag Handling

Solution Overview

Problem

Existing vacuum packaging and sealing appliances cannot effectively vacuum seal liquids such as soups and sauces without sucking them out, leading to messes and incomplete seals.

Innovation Solution

A vacuum packaging and sealing appliance with a uniquely shaped profile to keep liquids upright and a pressure sensor system that monitors pressure inside the bag, allowing controlled vacuuming and heat sealing to prevent liquid loss, enabling the appliance to handle various liquid thicknesses and types.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a conventional vacuum sealer is used to vacuum seal liquids, then the vacuum sealing function is achieved, but the liquid is sucked out of the bag causing mess and incomplete seals

Engineering Contradiction:

Improvevacuum sealing effectivenessVSAvoidliquid loss

Core Design Contradiction:

ReliabilityVSLoss of substance

Solution Approach 1:

The appliance performs preliminary actions by freezing the liquid contents before vacuum sealing. This pre-freezing step transforms the liquid into a solid or semi-solid state, preventing it from being sucked out during the vacuum process while still allowing effective vacuum sealing of the bag

Inventive Principle:

Principle #10Preliminary action

2Loss of substance

If manual intervention or pre-freezing is required to vacuum seal liquids, then liquid loss is prevented, but the ease of operation is reduced

Engineering Contradiction:

Improveliquid loss preventionVSAvoidoperational convenience

Core Design Contradiction:

Loss of substanceVSEase of operation

Solution Approach 1:

The appliance performs preliminary actions by freezing the liquid contents before vacuum sealing. This pre-freezing step transforms the liquid into a solid or semi-solid state, preventing it from being sucked out during the vacuum process while still allowing effective vacuum sealing of the bag

Inventive Principle:

Principle #25Self-service

3Stress or pressure

If the vacuum pump runs continuously to achieve strong vacuum, then vacuum strength is improved, but liquid is drawn out of the bag

Engineering Contradiction:

Improvevacuum pressureVSAvoidliquid suction

Core Design Contradiction:

Stress or pressureVSLoss of substance

Solution Approach 1:

The appliance performs preliminary actions by freezing the liquid contents before vacuum sealing. This pre-freezing step transforms the liquid into a solid or semi-solid state, preventing it from being sucked out during the vacuum process while still allowing effective vacuum sealing of the bag

Inventive Principle:

Principle #10Preliminary action

AI summary

An appliance is provided that is able to vacuum and heat seal plastic bag members containing liquids such as sauces and soups. The appliance may take on a uniquely shaped profile to allow the liquid to sit upright within a bag during the vacuuming process. The appliance also preferably includes a pressure sensor to constantly monitor pressure inside of the bag during the vacuum and sealing process. This may help to prevent liquid from being sucked up and into the appliance.
