Solution Overview

Problem

Modern cooking devices require users to navigate complex input mechanisms and suffer from inadequate display features, leading to inefficiencies and errors in operation.

Innovation Solution

A touch-sensitive display with a virtual timeline and virtual track allows users to intuitively select and adjust operation start times, displaying instance blocks that represent cooking device operations, enabling real-time progress tracking and control of heating elements based on user input.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If traditional input mechanisms (buttons, switches, knobs) are used in cooking devices, then the device can be operated, but the operation becomes time-consuming and error-prone

Engineering Contradiction:
Improveease of operationVSAvoidoperational time
Core Design Contradiction:
Ease of operationVSLoss of time

Solution Approach 1:

The patent replaces traditional mechanical input mechanisms (buttons, switches, knobs) with a touch-sensitive display interface. This substitution allows users to interact with the cooking device through graphical user interface elements on a display screen, eliminating the need for physical mechanical components and enabling more intuitive and efficient operation.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent creates visual representations (copies) of operational parameters and cooking states on the display screen. Users can view and adjust cooking parameters through graphical interfaces that replicate the actual cooking process, allowing for easier monitoring and control without direct mechanical interaction.

Inventive Principle:
Principle #26Copying

2Loss of information

If traditional display features are used in cooking devices, then information can be conveyed to the user, but the user requires more time to extract relevant information

Engineering Contradiction:
Improveinformation conveyanceVSAvoidinformation extraction time
Core Design Contradiction:
Loss of informationVSLoss of time

Solution Approach 1:

The patent segments information presentation into distinct visual elements on the display, including graphical icons, colored indicators, and organized sections for different cooking parameters. This segmentation allows users to quickly locate and understand specific information without sifting through unorganized text or symbols.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent utilizes color changes and visual indicators on the display to convey cooking status and parameter changes. Different colors represent different cooking states, providing immediate visual feedback to users and enabling rapid information extraction without requiring detailed reading or interpretation.

Inventive Principle:
Principle #32Color changes
