Container including agitator for microwave sous vide function

Solution Overview

Problem

Conventional sous vide cooking devices are separate appliances that require storage and often necessitate pre-heating water, lacking integration with existing kitchen equipment for efficient temperature control.

Innovation Solution

A microwave oven container with an integrated agitator driven by the turntable assembly, featuring a cage to separate the agitator from sous vide bags and a temperature sensor to maintain constant water temperature during cooking, utilizing the microwave oven's cooking element and controller for sous vide cooking.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If conventional sous vide cooking devices are used, then precise temperature control is achieved, but device complexity and storage requirements increase

Engineering Contradiction:
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent combines the sous vide cooking function with a standard microwave oven by integrating a heating element, temperature sensor, and circulation pump into the microwave's existing structure. This merging eliminates the need for a separate sous vide appliance while maintaining precise temperature control through the microwave's controller that coordinates between the cooking element and temperature sensor.

Inventive Principle:
Principle #5Merging (Combining)

2Measurement precision

If conventional sous vide devices with built-in water reservoirs are used, then temperature control is maintained, but loss of time for pre-heating water occurs

Engineering Contradiction:
Core Design Contradiction:
Measurement precisionVSLoss of time

Solution Approach 1:

The system performs preliminary heating of the water bath using the microwave's high-power cooking element before the actual sous vide cooking begins. The controller monitors temperature continuously and activates the heating element in advance to reach the target temperature, eliminating the need for separate pre-heating steps that would otherwise be required with conventional devices.

Inventive Principle:
Principle #10Preliminary action

3Stability of the object's composition

If an agitator is added to circulate water, then temperature uniformity is improved, but device complexity increases

Engineering Contradiction:
Core Design Contradiction:
Stability of the object's compositionVSDevice complexity

Solution Approach 1:

The circulation pump is designed to be driven by the microwave's existing turntable motor through a coupling mechanism. The turntable motor, which already exists in the microwave for rotating the plate, is repurposed to drive the pump that circulates water. This self-service approach uses the microwave's own motor to power the circulation function, avoiding the need for a separate dedicated motor and reducing overall device complexity.

Inventive Principle:
Principle #25Self-service
