Solution Overview

Problem

Existing vacuum packaging devices for kitchen use are complex, costly, and inefficient, particularly in terms of design and space usage within kitchen cabinets.

Innovation Solution

A vacuum packaging arrangement integrated into a kitchen cabinet drawer, featuring a clamp and weld type vacuum packaging device that operates without a vacuum chamber, allowing for cost-effective and space-efficient vacuuming of food items by using a drawer with a built-in vacuum packaging device that can be easily operated and configured for use within the cabinet.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a lid type vacuum machine is used in kitchen cabinets, then vacuum packaging can be achieved, but the device complexity and construction cost increase significantly

Engineering Contradiction:
Improvevacuum packaging capabilityVSAvoiddevice construction complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The vacuum packaging device is divided into separate functional modules: a vacuum pump unit, a control unit, and a user interface. These modular components can be independently manufactured, assembled, and maintained, reducing overall device complexity while preserving vacuum packaging functionality.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The vacuum packaging device is designed to perform multiple functions including vacuum sealing, storage, and integration with kitchen cabinet systems. This multi-functionality reduces the need for separate dedicated devices, simplifying the overall kitchen system architecture.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Reliability

If a lid type vacuum machine is installed in kitchen cabinets, then vacuum packaging is possible, but the product price and installation cost increase

Engineering Contradiction:
Improvevacuum packaging functionalityVSAvoidproduct cost
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

The vacuum pump is extracted as a separate, removable component from the main device body. This allows the vacuum pump to be manufactured independently using optimized processes and assembled into the final device, reducing overall manufacturing costs while maintaining vacuum packaging capability.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The design allows for cost-effective replacement of the vacuum pump as a consumable component rather than requiring the entire device to be replaced. This approach reduces the initial product price while maintaining long-term functionality through affordable maintenance.

Inventive Principle:
Principle #27Cheap short-living objects (Disposable)

3Reliability

If traditional vacuum sealing methods are used, then food can be vacuum packaged, but the space required in kitchen cabinets increases

Engineering Contradiction:
Improvevacuum sealing capabilityVSAvoiddevice volume
Core Design Contradiction:
ReliabilityVSVolume of moving object

Solution Approach 1:

The vacuum packaging device is designed to be nested within the kitchen cabinet drawer structure. The device housing utilizes the drawer's existing walls and space, allowing the vacuum pump and control components to be compactly arranged within the drawer's volume rather than requiring separate dedicated space.

Inventive Principle:
Principle #7Nested doll (Nesting)

Solution Approach 2:

The device utilizes the vertical dimension of the drawer space efficiently, with components arranged in a compact vertical configuration rather than spreading out horizontally. This dimensional optimization reduces the device's footprint while maintaining all necessary vacuum packaging functions.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

4Ease of operation

If the drawer is pulled out for operation, then the vacuum packaging device is accessible, but the connector interface must maintain electrical connection throughout the movement

Engineering Contradiction:
Improvedevice accessibilityVSAvoidconnector interface complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The connector interface is designed as a dynamic system that automatically engages and disengages based on the drawer position. When the drawer is pulled out to the operating position, the connector automatically connects to the power supply; when the drawer is closed, the connector automatically disconnects. This dynamic behavior simplifies the interface design while maintaining continuous electrical connection during operation.

Inventive Principle:
Principle #15Dynamics

AI summary

The present application in particular is related to a vacuum packaging arrangement. The vacuum packaging arrangement (2) comprises a drawer (4) configured to cooperate with a kitchen cabinet (3), and a vacuum packaging device (5). The vacuum packaging device (5) is functionally integrated in a ready-to-operate configuration within the drawer (4) and provides, within the drawer, an operational interface to receive a minor first section (27) of a vacuum bag (17), and to vacuum the vacuum bag upon activation of the vacuum packaging device (5). The vacuum packaging device (5) is implemented such that a major second section of the vacuum bag (17) comprising a closed end of the vacuum bag (17) is arranged outside of the vacuum packaging device (5).
