Fondue Induction Heating With Estimated Vessel Temperature Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Specialty food heating appliances often rely on linear heating protocols, leading to inefficient temperature control, with foods being heated too slowly or overheated, and typically lack actual temperature estimation, resulting in suboptimal cooking outcomes.
Innovation Solution
An induction heating system with a control system that estimates the actual temperature of an induction-compatible cooking vessel and adjusts the induction heater to maintain a desired temperature within a predetermined threshold, using predefined temperature curves for specific foods like chocolate fondue, cheese fondue, and bourguignonne.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If linear heating protocols are used, then the heating process is simple to implement, but the food is heated too slowly or overheated resulting in suboptimal cooking outcomes
Solution Approach 1:
The patent implements dynamic heating protocols that adjust heating parameters in real-time based on the cooking stage. The system transitions from high-power melting phase to lower-power maintenance phase, adapting the heating intensity to the current state of the food rather than using a fixed linear protocol. This resolves the contradiction by making the heating process dynamic and responsive, improving temperature control precision without requiring overly complex manual intervention.
Solution Approach 2:
The system uses temperature sensors and control algorithms to continuously monitor the actual temperature and compare it with the desired temperature profile. Based on this feedback, the controller adjusts the heating power to maintain optimal temperature ranges. This feedback mechanism enables precise temperature control while automating the complexity, so users benefit from precise control without directly managing the complex protocol.
2Adaptability or versatility
If traditional electric heaters or open flames are used, then the heating method is simple and widely available, but the temperature adjustment is hard to optimize for specific foods
Solution Approach 1:
The patent implements pre-configured heating profiles with specific temperature parameters for different food types (chocolate fondue, cheese fondue, bourguignonne, hot pot). Each profile contains optimized temperature ranges and heating rates tailored to the specific thermal requirements of each food. The system automatically selects and applies the appropriate parameter set based on the chosen food type, providing food-specific optimization while keeping the user interface simple.
Solution Approach 2:
The heating system is designed to handle multiple types of fondue and hot pot dishes through a single unified platform. By incorporating various pre-programmed profiles and allowing custom temperature settings, the system achieves multi-functionality that adapts to different culinary requirements. This resolves the contradiction by making one device versatile enough to optimize for multiple food types while maintaining ease of operation through automated profile selection.
3Reliability
If continuous cooking process is used, then the food remains heated, but the food is heated too slowly or overheated
Solution Approach 1:
The system employs periodic heating cycles with distinct phases: an initial high-power heating phase to reach target temperature, followed by a lower-power maintenance phase that periodically adjusts heating to compensate for heat loss. The controller continuously monitors temperature and applies periodic corrections rather than continuous high-power heating. This periodic action maintains reliable food temperature while preventing overheating and improving temperature accuracy throughout the cooking process.

AI summary
An induction heating system includes an induction heater, a user interface for setting a desired temperature value of induction heater, and a cooking vessel. The cooking vessel is formed of an induction-compatible material and includes a base, an exterior wall, and an interior surface. A control system is configured to receive the desired temperature value of the induction heater, estimate an actual temperature value of the cooking vessel, and compare the estimated temperature value with the desired temperature value. If a difference between the estimated and desired temperature values is outside of a predetermined threshold, the control system adjusts the induction heater until the difference between the estimated and desired temperature values is within the predetermined threshold.
