Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple induction cookers are placed in a large space, then the cooking capacity is improved, but it becomes difficult to pair pads with their respective induction cookers
Solution Approach 1:
The system uses RF communication to establish bidirectional feedback between pads and induction cookers. Each pad transmits its ID to the cooker, and the cooker confirms pairing by responding with its ID. This automated feedback mechanism eliminates manual pairing difficulties even when multiple cookers are deployed in large spaces.
Solution Approach 2:
The patent replaces manual mechanical pairing operations with automated RF (radio frequency) communication. Instead of physically connecting or manually configuring pads with cookers, the system uses wireless electromagnetic signals to automatically establish pairings, making the process independent of physical proximity or manual intervention.
2Object-affected harmful factors
If under-induction cookers are installed under tables to avoid contamination, then cleanliness is improved, but the possibility of fire due to mishandling increases
Solution Approach 1:
Temperature sensors continuously monitor the cooking surface and provide real-time feedback to the controller. When the temperature exceeds the preset threshold, the system automatically responds by shutting off power to the induction cooker, preventing fire hazards without requiring external intervention.
Solution Approach 2:
The system performs self-protection through automated temperature monitoring and emergency shutdown capabilities. The controller independently detects overheating conditions and terminates operation without user input, making the safety mechanism self-activating and reliable even when the cooker is hidden under tables.
3Reliability
If temperature monitoring is continuously performed, then safety is improved, but energy consumption increases
Solution Approach 1:
Temperature monitoring is performed periodically rather than continuously. The controller checks temperature at specific intervals during operation, maintaining adequate safety monitoring while reducing energy consumption compared to continuous real-time monitoring. This periodic sampling approach balances safety requirements with energy efficiency.

Function Achieved in This Case
The system enables accurate and safe operation of under-induction cooking by ensuring one-to-one pairing of induction cookers with pads, preventing accidents like fires through diverse control mechanisms and multiple safety features.
Implementation Method 1
lines of magnetic force produced when a high-frequency current is applied pass through a bottom of an induction cooking container laid on a top plate of the induction cooker, at which point an eddy current generated by a resistance component only heats the induction cooking container
Implementation Method 2
one or more pads, wherein each pad includes a sender transmitting a radio frequency (RF) signal... one or more induction units fixed under each table... a first sensor portion detecting a magnetic field generated by the magnet portion
