Solution Overview

Problem

Existing cooking systems lack user-friendly features that minimize cooking time and prevent operator errors, such as forgetting actions or improper utensil placement, which can lead to inefficient cooking and safety issues.

Innovation Solution

A cooking system with a hob plate and a display unit positioned near the cooking utensil area, controlled by a unit that provides operating prompts via optical, acoustic, or haptic means, ensuring the operator is informed about actions to perform, and utilizing induction heating elements to power the display unit for energy efficiency and flexibility.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a display unit is added to provide operating prompts and real-time feedback, then user convenience and cooking efficiency are improved, but device complexity increases

Engineering Contradiction:
Improveuser convenienceVSAvoiddevice complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The display unit is integrated into the cooking system by positioning it in the immediate vicinity of the cooking utensil positioning area on the hob plate, merging the display function with the existing cooking structure. This integration provides operating prompts and real-time feedback without requiring a separate standalone display device, thereby improving user convenience while controlling the increase in overall system complexity.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The display unit acts as an intermediary between the control unit and the user, translating operating parameters and system status into visual or tactile feedback that the user can easily understand. This intermediary function simplifies the user interface and improves ease of operation by providing clear, context-relevant information at the point of interaction.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Ease of operation

If the display unit is positioned in the immediate vicinity of the cooking utensil positioning area, then operating convenience is improved, but the area available for cooking utensils is reduced

Engineering Contradiction:
Improveoperating convenienceVSAvoidcooking utensil positioning area
Core Design Contradiction:
Ease of operationVSArea of stationary object

Solution Approach 1:

The display unit is positioned in the immediate vicinity of the cooking utensil positioning area rather than occupying the entire hob plate surface. This localized placement provides operating prompts and feedback at the relevant location for user interaction while preserving the majority of the hob plate area for cooking utensil placement, thus balancing operating convenience with cooking space availability.

Inventive Principle:
Principle #3Local quality

3Use of energy by moving object

If induction heating elements are used to power the display unit, then energy efficiency is improved, but the system requires precise positioning for optimal energy transfer

Engineering Contradiction:
Improveenergy efficiencyVSAvoidpositioning precision
Core Design Contradiction:
Use of energy by moving objectVSMeasurement precision

Solution Approach 1:

The induction heating elements serve a dual function: heating cooking utensils and powering the display unit. The system automatically manages the energy transfer and positioning requirements, with the control unit coordinating the induction elements to provide both cooking heat and display power without requiring manual intervention for energy management or precise manual positioning.

Inventive Principle:
Principle #25Self-service
