Dual-Oven Cooking Platform Power Sharing Under Circuit Limits
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cooking platforms face limitations in incorporating high-powered appliances due to power supply constraints, as activating multiple high-powered appliances simultaneously exceeds the available power limit, risking system overload and breaker tripping.
Innovation Solution
A power management system that distributes power between a first and second electric cooking element, where the second electric cooking element is energized by de-energizing the first electric cooking element, allowing for simultaneous use without exceeding the power rating, using a controller, thermostat, and switches to manage power allocation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If additional high-powered appliances are incorporated into the cooking platform, then versatility and consumer benefits are improved, but the risk of system overload and breaker tripping increases when multiple appliances are activated simultaneously
Solution Approach 1:
The patent implements dynamic power management by continuously monitoring the power consumption of active appliances and adjusting the power delivery in real-time. The controller dynamically allocates available power among multiple appliances based on their current operational status, allowing the system to adapt to changing power demands without exceeding the power supply limit. This dynamic approach enables the cooking platform to provide high-powered appliances with full power when needed while preventing system overload through automated power distribution control.
2Reliability
If the power rating of individual appliances is decreased to safeguard against system overload, then system reliability is improved, but the cooking performance and consumer satisfaction deteriorate
Solution Approach 1:
The patent implements a universal power management controller that serves multiple functions: monitoring power consumption, allocating power distribution, and controlling power delivery to various appliances. This multi-functional controller enables each appliance to maintain its full power rating capability while the system as a whole remains protected from overload. The controller universally manages power distribution across all appliances, allowing any single appliance to operate at maximum power when it is the only active device, thus preserving cooking performance while ensuring system safety.
3Productivity
If multiple high-powered appliances are designed to operate simultaneously, then consumer convenience and productivity are improved, but the power supply limit is exceeded causing breaker tripping
Solution Approach 1:
The patent implements preliminary power allocation by pre-establishing power distribution rules and thresholds for different appliance combinations. Before appliances are activated, the system is configured with knowledge of their power requirements and the available power supply limit. The controller proactively manages power distribution by allocating available power to appliances based on pre-defined priorities and consumption patterns, preventing power overload before it occurs. This preliminary action approach enables multiple high-powered appliances to be designed for simultaneous operation while the system proactively prevents exceeding the power supply limit through anticipatory power management.

Function Achieved in This Case
Enables the simultaneous use of high-powered appliances without overloading the electrical circuit, ensuring safe operation and satisfying consumer demands by optimizing power usage within the existing power supply limits.
Implementation Method 1
a first oven (102) having a first electric cooking element (106), and a second oven (200) having a second electric cooking element (202)
Data Source
AI summary
A household range includes a first oven having a first electric cooking element, and a second oven includes a second electric cooking element. A power management system is used to distribute power such that when the second electric cooking element is energized the first electric cooking element is de-energized.
