Solution Overview

Problem

Existing systems with inductive hobs lack efficient user-friendly operation, proper handling protection, and energy management, often leading to potential damage and safety hazards due to inadequate recognition of installation events and surface conditions.

Innovation Solution

A set-up device equipped with sensors, such as vibration or acceleration sensors, that automatically recognizes installation events and surface conditions, enabling controlled operation, reducing energy consumption, and preventing improper handling by only activating necessary components when correctly set up on an inductive hob.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the inductive hob operates without sensor-based detection, then the system structure remains simple, but user convenience deteriorates and safety hazards increase due to inability to detect setup events and surface conditions

Engineering Contradiction:
Improveuser convenienceVSAvoidsystem structure
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The stand-alone appliance performs self-detection of setup events and surface conditions using integrated sensors (acceleration, vibration, temperature), eliminating the need for complex manual setup procedures and providing automatic recognition of cooking context

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The system establishes bidirectional communication between the stand-alone appliance and inductive hob through sensor data transmission, enabling real-time feedback loops where the appliance reports its state and the hob adjusts operation accordingly, improving user convenience through automatic adaptation

Inventive Principle:
Principle #23Feedback

2Measurement precision

If the inductive hob continuously monitors all parameters, then detection accuracy improves, but energy consumption increases due to constant sensor operation and data transmission

Engineering Contradiction:
Improvedetection accuracyVSAvoidenergy consumption
Core Design Contradiction:
Measurement precisionVSUse of energy by moving object

Solution Approach 1:

The sensor system operates in periodic intervals rather than continuously, with the stand-alone appliance activating sensors to detect setup events and surface conditions at specific moments, thereby maintaining detection accuracy while reducing energy consumption during non-critical periods

Inventive Principle:
Principle #19Periodic action

Solution Approach 2:

The system performs preliminary detection of setup events and surface conditions before initiating full cooking operation, allowing the inductive hob to prepare appropriately in advance while avoiding continuous monitoring during stable operating states

Inventive Principle:
Principle #10Preliminary action

3Reliability

If the stand-alone appliance lacks sensor-based setup detection, then the device remains simple, but reliability deteriorates due to inability to prevent improper handling and safety hazards

Engineering Contradiction:
Improveprotection against improper handlingVSAvoidappliance structure
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The sensor system detects improper handling conditions (such as placement on non-inductive surfaces or incorrect positioning) before they can cause damage, enabling the system to prevent harmful operations from occurring in the first place through preliminary detection and response

Inventive Principle:
Principle #9Preliminary anti-action
