Solution Overview

Problem

Existing hobs lack a cost-effective and comfortable design for operator interaction, particularly in detecting and responding to movements of cooking utensils, which limits flexibility and convenience.

Innovation Solution

Integration of an acceleration sensor within the control panel of the hob device to detect movements, allowing for precise and cost-effective operation without the need for additional pot detection systems, and enabling wireless communication with a control unit to adjust heating parameters based on detected movements.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If a sensor unit with accelerometer is integrated into the control panel, then movement detection precision is improved, but device complexity increases

Engineering Contradiction:
Improvemovement detection precisionVSAvoiddevice complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The sensor unit including the accelerometer is integrated into the control panel housing, merging the detection function with the existing control structure. This consolidation improves movement detection precision while avoiding the need for separate detection systems, thereby limiting the increase in device complexity.

Inventive Principle:
Principle #5Merging (Combining)

2Adaptability or versatility

If additional pot detection systems are added, then cooking vessel detection capability is improved, but cost increases

Engineering Contradiction:
Improvecooking vessel detection capabilityVSAvoidmanufacturing cost
Core Design Contradiction:
Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The sensor unit with accelerometer serves multiple functions: it detects movements of the control panel, identifies placement of cooking vessels, and monitors removal of vessels. This multi-functionality improves cooking vessel detection capability while using the same hardware component, thereby avoiding additional costs for separate detection systems.

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

3Ease of operation

If the control panel is designed as a detachable cooking vessel handle, then ease of operation is improved, but reliability of connection decreases

Engineering Contradiction:
Improveease of operationVSAvoidconnection reliability
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The sensor unit provides feedback about the connection state by detecting movements and positions of the control panel relative to the cooking vessel. This feedback mechanism allows the system to monitor and confirm proper attachment, thereby maintaining connection reliability despite the detachable design that improves ease of operation.

Inventive Principle:
Principle #23Feedback
