Solution Overview

Problem

Residential cooking appliances that utilize multiple energy sources lack a user-friendly interface for selecting and adjusting cooking options, limiting versatility and convenience for homeowners who want to cook a variety of dishes quickly without sacrificing taste and quality.

Innovation Solution

A multi-modality knob or controller system that guides users through a series of prompts using a menu-driven display, allowing for easy selection of cooking modes, sub-categories, and adjustments, with features for saving favorite settings and downloading additional cooking parameters via various communication methods.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a menu-driven display with multiple prompts is used to guide users through cooking selections, then the versatility and precision of cooking options are improved, but the complexity of the interface and operation time increase

Engineering Contradiction:
Improvecooking optionsVSAvoidinterface complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The controller is divided into multiple independent rotary knobs, each dedicated to a specific cooking parameter (e.g., one knob for cooking mode, another for temperature, another for time). This segmentation allows users to adjust each parameter independently without navigating through complex menus, thereby maintaining high versatility while reducing interface complexity.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Physical rotary knobs serve as intermediary devices between the user and the electronic control system. These knobs provide tactile feedback and intuitive mechanical interaction, mediating the complexity of digital menu navigation by translating simple rotational movements into precise parameter selections.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Ease of operation

If multiple rotary knobs are provided for different cooking parameters, then the ease of operation and user-friendliness are improved, but the device complexity and number of components increase

Engineering Contradiction:
Improveuser-friendlinessVSAvoidnumber of components
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

Each rotary knob is designed to be multi-functional, capable of selecting among multiple cooking parameters depending on the active cooking mode. For example, a single knob may control temperature during baking mode but control cooking time during grilling mode, reducing the total number of knobs needed while maintaining ease of operation.

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

Solution Approach 2:

The controller interface dynamically adapts its functionality based on the selected cooking mode. The knobs' available options and ranges change automatically depending on what is being cooked, providing context-appropriate controls without requiring physical reconfiguration or additional components.

Inventive Principle:
Principle #15Dynamics

3Productivity

If commercial-style ovens with multiple energy sources are adapted for residential use, then the cooking speed and efficiency are improved, but the interface complexity and difficulty of operation increase

Engineering Contradiction:
Improvecooking speedVSAvoiddifficulty of operation
Core Design Contradiction:
ProductivityVSEase of operation

Solution Approach 1:

The oven system automatically determines which energy sources to use based on the selected cooking mode and food type. The controller autonomously manages the complexity of coordinating multiple energy sources (convection, microwave, steam), allowing users to simply select the desired outcome without manually configuring each energy source.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The display screen provides real-time feedback about the cooking status, energy sources in use, and timer progression. This feedback mechanism helps users understand what the oven is doing with multiple energy sources, reducing perceived complexity and making the high-productivity system easier to operate.

Inventive Principle:
Principle #23Feedback
