Handheld Vacuum Sealer One-Step Activation and 360 Charging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing handheld cordless vacuum sealers require two steps for operation and have complex charging requirements, including the need for specific device orientation during charging.
Innovation Solution
A handheld cordless vacuum sealer with a rotary diaphragm pump for quiet operation, powered by 1/3 AA Ni-MH batteries, featuring a large activation button for one-step sealing and a 360° electrical charging base for orientation-independent charging, along with a cord wrap feature for convenient storage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a handheld vacuum sealer requires two steps for operation (pushing down to form seal and depressing activation button), then the device can maintain separate control functions, but the operation complexity increases and user convenience deteriorates
Solution Approach 1:
The patent combines the sealing and activation functions into a single integrated button mechanism. When the user presses the device down onto the vacuum port, the same action both forms the seal and activates the vacuum pump, eliminating the need for a separate activation step while maintaining functional control
2Reliability
If the vacuum sealer uses a traditional charging cradle requiring specific device orientation, then charging contacts can be precisely aligned, but the charging process becomes more complex and less convenient
Solution Approach 1:
The patent transitions from a single-point charging contact to a 360-degree charging base with charging contacts distributed around the entire circumference. This allows the device to be charged in any orientation by making contact at multiple points around the base, eliminating the need for specific device orientation while ensuring reliable electrical connection
3Volume of moving object
If the activation button is placed on the side of the vacuum sealer, then the device layout can be compact, but the button becomes difficult to press when the device is positioned for sealing
Solution Approach 1:
Instead of placing the activation button on the side of the device where it would be compact but inaccessible, the patent inverts the approach by making the entire sealing surface act as the activation mechanism. The act of pressing down to seal becomes the activation action itself, with the button positioned on top for easy access when the device is in use
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
Enables efficient one-step vacuum sealing and simplified charging, reducing user effort and increasing convenience by allowing the device to be charged in any orientation, thus improving usability and reducing food spoilage through enhanced preservation.
Implementation Method 1
A handheld cordless vacuum sealer is provided for use with FoodSaver containers, zipper bags, and accessories to remove air from within the containers, bags, or accessories and preserve freshness of food stored therein

AI summary
A handheld vacuum sealer device is provided for drawing a vacuum to remove air from a bag or container to prolong freshness of food stored in the bag or container. The sealer device includes an activation button to initiate drawing the vacuum that is activated at the same time a user pushes downwardly on the sealer device to form a seal between the sealer device and the bag or container. A charging cradle for recharging the sealer device is also provided that charges the sealer device regardless of the orientation of the sealer device when the sealer device is placed within the charging cradle.
