Solution Overview
Problem
Cooking appliances often result in messes, such as boiling over, splattering, and burning, which can be hazardous and challenging for inexperienced users, especially when handling multiple recipes simultaneously, as they require constant attention and monitoring.
Innovation Solution
A cooking assistance appliance equipped with sensors, including cameras and infrared sensors, that monitor the cooking surface, detect mess conditions, and project alerts or instructions to prevent or mitigate messes, while also estimating liquid levels and boiling times, thereby reducing user intervention and improving safety and efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a user monitors the cooking surface continuously to detect messes, then mess detection accuracy is improved, but user time and attention are consumed
Solution Approach 1:
The cooking appliance performs self-monitoring through integrated sensors (optical, thermal, acoustic) that automatically detect mess conditions without requiring user attention. The system serves itself by continuously monitoring its own cooking surface and issuing alerts when messes are detected
Solution Approach 2:
The manual monitoring action is replaced by an automated sensor-based detection system. Optical sensors, thermal sensors, and acoustic sensors substitute for human visual and auditory monitoring, enabling continuous mess detection without consuming user time
2Measurement precision
If multiple sensors are integrated to improve mess detection capability, then detection accuracy is improved, but device complexity increases
Solution Approach 1:
A single controller integrates multiple sensor types (optical, thermal, acoustic) into one unified mess detection system. The controller performs multiple functions: processing optical sensor data, analyzing thermal patterns, evaluating acoustic signals, and coordinating alert generation, thereby managing complexity through functional integration
Solution Approach 2:
Multiple sensing modalities are merged into a coordinated detection system where optical sensors detect visual mess indicators, thermal sensors monitor temperature anomalies, and acoustic sensors listen for boiling or splashing sounds. These merged sensor inputs are processed together by a single controller to comprehensively detect mess conditions
3Reliability
If real-time monitoring is implemented to prevent messes, then safety is improved, but energy consumption increases
Solution Approach 1:
Instead of continuous high-power monitoring, the system uses periodic sensing cycles where sensors are activated at intervals to check for mess conditions. The controller periodically analyzes sensor data and only activates alert mechanisms when mess indicators are detected, reducing overall energy consumption while maintaining safety
Solution Approach 2:
The system implements feedback control by continuously monitoring sensor inputs and adjusting its monitoring intensity based on cooking stage and risk level. During high-risk cooking phases, monitoring frequency increases, while during stable phases, monitoring reduces, optimizing energy consumption according to actual safety needs
