Electric pot having improved function of continuing temperature-maintenance operation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electric pots require users to manually reset and wait for a temperature-maintenance operation after re-coupling the pot and base, which is cumbersome and inconvenient, especially when reusing the pot for tasks like steeping tea.
Innovation Solution
An electric pot with a controller and memory system that stores and retrieves temperature-maintenance operation settings, allowing the pot to automatically resume the temperature-maintenance operation when re-coupled, using a power module and temperature sensor to determine if the operation should be re-initiated based on stored data and content quantity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the temperature-maintenance operation is stopped when the body is separated from the base, then safety is improved by cutting off power, but user convenience deteriorates as the operation cannot be resumed automatically
Solution Approach 1:
The controller stores operation information (temperature, time, power state) in a memory before the body is separated from the base. This preliminary recording of operational data enables the system to automatically resume the temperature-maintenance operation after re-coupling, eliminating the need for manual re-setting and improving user convenience while maintaining safety protocols
2Use of energy by moving object
If the user must re-set the temperature-maintenance operation after re-coupling, then power consumption is reduced by stopping the operation, but time is lost requiring the user to re-configure settings
Solution Approach 1:
The controller records the temperature-maintenance operation parameters (target temperature, duration, power state) in a memory before separation occurs. When the body is re-coupled to the base, the controller automatically retrieves this stored information and resumes the operation without requiring user re-configuration, thus eliminating time loss while managing power consumption through selective resumption based on stored state information
3Extent of automation
If the controller continuously monitors and stores operation data, then automation is improved enabling seamless resumption, but device complexity increases with additional memory and control logic
Solution Approach 1:
The controller implements a simple memory storage mechanism that records essential operation information (temperature, time, power state) before separation. This preliminary data capture uses basic storage components and straightforward control logic to enable automatic resumption, achieving high automation without significantly increasing device complexity through overly complex systems
Solution Approach 2:
The controller automatically retrieves and processes the stored operation information without requiring external intervention or complex decision-making algorithms. The system serves itself by autonomously resuming the temperature-maintenance operation based on pre-stored data, achieving automation through simple self-service mechanisms rather than complex control systems

AI summary
An electric pot may include a controller that controls a heater to perform a temperature-maintenance operation based on an input relating to a temperature-maintenance operation and based on information on temperatures. A memory may receive information in relation to a temperature-maintenance operation from the controller and may store the information and retain the stored information in relation to a temperature-maintenance operation regardless of whether a pot main body is attached to or detached from a supporter.
