Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Extent of automation

If conventional cooking appliances are used, then cooking can be performed with simple appliances, but automated production of complex meals with precision and consistency cannot be achieved

Engineering Contradiction:
Improveautomated cooking productionVSAvoidcooking appliance system
Core Design Contradiction:
Extent of automationVSDevice complexity

Solution Approach 1:

The cooking appliance is divided into multiple independent heating zones (first heating zone, second heating zone, third heating zone) that can be controlled separately. Each zone has its own heating elements and can operate with different parameters, enabling complex multi-stage cooking processes to be automated through independent control of each segment.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The cooking appliance integrates multiple cooking functions into a single device, including convection heating, infrared heating, and microwave heating capabilities. The heating elements can operate in different modes and combinations, allowing the appliance to emulate various conventional cooking methods (baking, roasting, grilling, steaming) while achieving automated precision cooking.

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

2Adaptability or versatility

If multiple cooking appliances are used to produce complex meals, then cooking versatility is achieved, but systematic automated production cannot be realized

Engineering Contradiction:

Solution Approach 1:

The cooking appliance integrates multiple cooking functions into a single device, including convection heating, infrared heating, and microwave heating capabilities. The heating elements can operate in different modes and combinations, allowing the appliance to emulate various conventional cooking methods (baking, roasting, grilling, steaming) while achieving automated precision cooking.

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

Solution Approach 2:

Multiple heating technologies (convection fans, infrared heating elements, microwave generators) are merged into a single integrated system. The control system coordinates these different heating methods to work together, combining their advantages to achieve versatile cooking capabilities in one appliance rather than requiring multiple separate devices.

Inventive Principle:
Principle #5Merging (Combining)

3Manufacturing precision

If real-time monitoring and control is implemented, then cooking precision is improved, but system complexity and cost increase

Engineering Contradiction:
Improvecooking result consistencyVSAvoidcontrol system
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The cooking appliance incorporates sensors that continuously monitor cooking parameters (temperature, humidity, cooking stage) and feed this information back to the control system. The controller adjusts heating element operation based on this feedback, automatically maintaining optimal cooking conditions and ensuring consistent results without requiring complex manual intervention.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The cooking process is dynamically adjusted through automated control of heating elements based on real-time cooking stage detection. The system can modify heating power, switch between different heating zones, and adapt cooking parameters mid-process to achieve optimal results, transforming static cooking programs into dynamic responsive cooking operations.

Inventive Principle:
Principle #15Dynamics

AI summary

Several embodiments include a cooking appliance. The cooking appliance can include one or more heating elements; a cooking chamber; and a camera attached to the interior of the chamber. In some embodiments, the cooking chamber prevents any visible light from escaping the chamber (e.g., the cooking chamber is windowless). In some embodiments, the heating elements are controlled by a computing device in the cooking appliance. In some embodiments, the output of the camera is used to adjust heating pattern of the heating elements.
