Solution Overview

Problem

Existing oven-powered cooking accessories lack effective communication and control mechanisms, limiting their functionality and compatibility with ovens due to restricted power output and lack of information exchange between accessories and ovens.

Innovation Solution

A powered cooking accessory with a device coupling that includes an identification element, allowing communication of characteristics to the oven, enabling the oven to provide tailored power and control options based on the accessory's configuration, such as steam cooking or baking, by using an identification element encoded with information about the accessory's type and configuration.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If an identification element is added to enable communication between accessory and oven, then functionality and compatibility are enhanced, but device complexity increases

Engineering Contradiction:
Improvefunctionality and compatibilityVSAvoiddevice complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The identification element is integrated within the device coupling structure, nesting the communication functionality inside the existing power connection component. This allows the accessory to communicate its characteristics to the oven through the same physical interface used for power delivery, enhancing functionality without adding separate external components.

Inventive Principle:
Principle #7Nested doll (Nesting)

Solution Approach 2:

The device coupling serves multiple functions: it provides electrical power delivery and simultaneously transmits identification information about the accessory characteristics. By making the coupling universal for both power and communication purposes, the system enhances adaptability while avoiding the complexity of separate dedicated communication hardware.

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

2Ease of operation

If customized power delivery based on accessory characteristics is implemented, then cooking control is optimized, but system complexity increases

Engineering Contradiction:
Improvecooking controlVSAvoidsystem complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The accessory automatically communicates its characteristics to the oven through the identification element in the device coupling. The oven system then automatically determines the appropriate power output level based on this information without requiring manual user configuration. This self-service approach optimizes cooking control while minimizing the complexity of user interaction.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The identification element provides feedback information about accessory characteristics to the oven, enabling the oven to automatically adjust power delivery according to the specific accessory being used. This feedback mechanism allows for optimized cooking control tailored to each accessory type without requiring complex manual programming by the user.

Inventive Principle:
Principle #23Feedback

AI summary

A method for operating a cooking system includes receiving information from a powered cooking accessory positioned within an interior cavity of an oven. The powered cooking accessory includes a body receivable within an interior of the oven, a first electronic device coupled with the body, and a device coupling extending from the body. The method further includes determining at least one characteristic of the powered cooking accessory and providing electrical power to the electronic device by an electrical coupling between the device coupling and a connection port within the interior cavity of the oven at a predetermined output level based on the at least one characteristic thereof.
