Solution Overview

Problem

Conventional microwave cooking devices are standalone and cannot be integrated with other kitchen implements, leading to increased costs and space requirements due to the need for multiple separate appliances for different cooking methods.

Innovation Solution

A microwave cooking apparatus with a lid and microwave producing device that can be manually lowered and positioned over traditional cooking sources or blending/mixing containers, allowing for combined microwave heating/cooking with open flame, induction, or blender/mixer grinder functionality, reducing the number of required kitchen implements and space.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If conventional microwave cooking devices are used as standalone appliances, then microwave heating functionality is provided, but the number of kitchen implements increases and space requirements increase

Engineering Contradiction:
Improveintegration capability with other kitchen implementsVSAvoidnumber of kitchen implements
Core Design Contradiction:
Adaptability or versatilityVSQuantity of substance

Solution Approach 1:

The patent combines a microwave generating device with a lid assembly into an integrated unit that can be placed over various cooking vessels. The microwave device includes a magnetron, waveguide, and shielding structure integrated within the lid, allowing simultaneous use with traditional cooking methods (gas, induction, electric) or blending operations, thereby reducing the need for separate microwave oven and other kitchen appliances

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The lid-integrated microwave device is designed to be universally compatible with multiple types of cooking vessels and cooking methods. It can function over gas stoves, induction cooktops, electric burners, or blending containers, providing multi-functionality that eliminates the need for separate specialized appliances for different cooking tasks

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

2Adaptability or versatility

If conventional microwave cooking devices are used as standalone appliances, then microwave heating functionality is provided, but space requirements in kitchen increase

Engineering Contradiction:
Improveintegration capability with other kitchen implementsVSAvoidspace requirement in kitchen
Core Design Contradiction:
Adaptability or versatilityVSArea of stationary object

Solution Approach 1:

By merging the microwave generating device with a lid assembly that can be placed over existing cooking vessels, the patent eliminates the need for a separate standalone microwave oven. The integrated unit utilizes the space above the cooking vessel, thereby reducing the overall space requirement in the kitchen while maintaining microwave heating functionality

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The invention transitions from a horizontal placement model (standalone microwave oven on counter) to a vertical placement model (lid-mounted microwave device above cooking vessel). This dimensional change allows the microwave functionality to be integrated into the vertical space above the stove, reducing horizontal counter space requirements

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

3Adaptability or versatility

If a lid with microwave producing device is made height-adjustable, then adaptability to different cooking vessels is improved, but device complexity increases

Engineering Contradiction:
Improvecompatibility with different cooking vesselsVSAvoidlifting and lowering mechanism complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The lid assembly incorporates a lifting and lowering mechanism that allows dynamic adjustment of the microwave device height relative to the cooking vessel. This dynamic positioning capability enables adaptation to different vessel sizes and cooking configurations, with the mechanism including adjustable support legs or telescopic elements that can be manually positioned to achieve proper sealing and microwave containment

Inventive Principle:
Principle #15Dynamics

AI summary

A cooking apparatus that combines microwave based heating/cooking with either of blender/mixer grinder functionality and traditional cooking using open flame and/or induction cooking is disclosed. The cooking apparatus comprises a lid and at least one microwave producing device coupled to the lid. A lifting and lowering mechanism carries the lid and microwave producing device at a lower end for enabling vertically raising and lowering the lid along with the coupled microwave producing device. Upper end of lifting and lowering mechanism is slid ably configured with a lower side of a chimney. Lid in lowered position gets operatively coupled with a container holding a food item. The container can be one for cooking food using conventional source of heat, or a container for preparatory operations such as blending, stirring, grinding and mixing. Coupling of the lid with the containers enables heating of the contents of the container through the microwaves generated by the at least one microwave producing device.
