Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If real-time power transmission monitoring and feedback display are implemented, then cooking efficiency is improved and energy waste is reduced, but device complexity increases due to additional sensors and control systems
Solution Approach 1:
The patent implements a feedback mechanism where the control device receives power transmission data from temperature sensors and pot detection devices, processes this information, and provides real-time feedback to the operator through a display unit. This feedback loop enables dynamic adjustment of cooking parameters to optimize power transmission and cooking efficiency while managing system complexity through intelligent control algorithms.
Solution Approach 2:
The system performs self-diagnosis and self-optimization by automatically monitoring power transmission efficiency, detecting pot characteristics, and providing guidance to operators about optimal cooking configurations. The control device autonomously processes sensor data to identify inefficiencies and recommends corrective actions, reducing the need for manual intervention and complex operator decisions.
2Measurement precision
If multiple sensors and detection devices are added to monitor power transmission and temperature, then measurement precision is improved, but device complexity and manufacturing cost increase
Solution Approach 1:
The patent designs the control device to perform multiple functions: it manages power supply to heating elements, receives and processes data from temperature sensors and pot detection devices, monitors power transmission in real-time, and provides feedback through the display unit. By consolidating these diverse functions into a single intelligent control device, the system achieves high measurement precision without proportionally increasing overall system complexity.
Solution Approach 2:
The control device merges the functions of power management, sensor data acquisition, data processing, and user interface control into a single integrated unit. This consolidation allows the system to implement sophisticated monitoring and measurement capabilities while avoiding the complexity that would arise from separate dedicated devices for each function.
3Loss of information
If the system provides detailed feedback and recommendations to operators, then loss of information is reduced and cooking process optimization is improved, but ease of operation may be reduced due to increased information processing requirements
Solution Approach 1:
The control device provides targeted feedback to operators based on real-time analysis of power transmission data and sensor readings. Rather than overwhelming operators with raw data, the system processes information and presents actionable insights, such as recommendations for optimal pot placement or heating power adjustments, thereby maintaining ease of operation while reducing information loss.
Solution Approach 2:
The control device acts as an intermediary between the complex sensor network and the operator. It translates raw sensor data and power transmission measurements into meaningful, easy-to-understand feedback and recommendations through the display unit, bridging the gap between sophisticated monitoring capabilities and simple user interaction.

AI summary
The method involves controlling a cooking hob (11) that is provided with several cooking areas (14a-14d). Each cooking area is provided with pan detection device (23a-23d) having pan detection function. A power transferred from hotplate to the pan to be heated is recognized for providing warning. The power transmitted to the pan is displayed on display (16) with respect to maximum power transferred as feedback from operator. A cooking process is performed based on correction of power transmitted to the pan. An independent claim is included for a cooking hob.
