Solution Overview

Problem

Conventional cooking appliances require users to exit a selected cooking program or manually adjust temperatures to implement a sear function, making the process inconvenient and time-consuming.

Innovation Solution

A cooking appliance with a touchscreen user interface that allows selection of a sear feature during an ongoing cooking program, increasing the temperature to a maximum without interrupting the program, and temporarily disabling the sear feature after a predetermined time regardless of reaching the maximum temperature.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If conventional cooking appliances require users to exit a selected cooking program or manually adjust temperatures to implement a sear function, then the sear function can be implemented, but the process becomes inconvenient and time-consuming

Engineering Contradiction:
Improveease of sear function selectionVSAvoidtime to implement sear
Core Design Contradiction:
Ease of operationVSLoss of time

Solution Approach 1:

The sear option is pre-configured and displayed on the touchscreen interface before the cooking program starts. Users can select the sear function in advance during program setup, so no manual temperature adjustment or program exit is needed when searing is desired. The system prepares the sear parameter settings beforehand, allowing immediate activation during cooking.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The cooking appliance automatically manages the temperature increase for searing without requiring user intervention to exit the program or manually adjust controls. When the user selects the sear option, the system self-manages the temperature transition and cooking program continuity, eliminating the need for manual operations that would otherwise be required.

Inventive Principle:
Principle #25Self-service

2Adaptability or versatility

If the sear feature is always available for selection during cooking, then users have maximum flexibility, but the interface may become confusing or allow inappropriate selections

Engineering Contradiction:
Improveflexibility of sear selectionVSAvoidinterface complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The availability of the sear option dynamically changes based on the cooking program state and timing. The sear option is displayed and selectable only during appropriate phases of the cooking program, and it automatically disappears after a predetermined time or when cooking conditions are no longer suitable for searing. This dynamic behavior provides flexibility when appropriate while maintaining interface simplicity by hiding the option when inappropriate.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The touchscreen interface provides visual feedback about when the sear option is available and when it has been selected. The system monitors cooking progress and automatically updates the interface to show or hide the sear option based on current temperature, time, and program stage, giving users clear feedback about appropriate sear timing without requiring them to understand complex cooking parameters.

Inventive Principle:
Principle #23Feedback
