Detachable Induction Cooker Lid With Wireless Power Coils
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cooking appliances with induction heating face challenges in maximizing the inner pot accommodation space while providing wireless power supply to electronic devices in the lid, maintaining a compact size, and ensuring easy lid detachment for cleaning and sanitation, all while avoiding the reduction of the inner pot accommodation space due to power supply components.
Innovation Solution
A cooking appliance design featuring a detachable lid with a storage space for electronic devices, a power transmission coil in the main body handle, and a power reception coil in the lid handle, allowing wireless power transfer and a controller to determine the fastening state between the lid and main body without additional parts, thus enhancing manufacturing efficiency and user convenience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If a main body-side upper induction coil is disposed inside the main body to supply current to the lid heating heater, then the lid can be heated, but the accommodation space for the inner pot decreases
Solution Approach 1:
The patent relocates the power transmission coil from the main body's internal space to the handle portion, utilizing a different spatial dimension (the handle extending outward from the main body). This allows the coil to be positioned outside the main accommodation space while still functioning to heat the lid through electromagnetic induction.
Solution Approach 2:
The patent introduces a lid-side induction coil as an intermediary component between the main body-side coil and the lid heating heater. The lid-side coil receives electromagnetic energy from the main body-side coil and transfers it to the heating heater, enabling indirect heating while optimizing space utilization.
2Adaptability or versatility
If power supply components are added to the lid for wireless power supply, then electronic devices can be powered, but the device complexity increases
Solution Approach 1:
The lid-side induction coil serves multiple functions: it acts as a power reception coil for wireless power supply to electronic devices in the storage space, and simultaneously functions as a heating element to transfer energy to the lid heating heater. This multi-functionality reduces overall system complexity.
Solution Approach 2:
The patent combines the power reception function and the lid heating function into a single integrated system using the lid-side induction coil. The coil receives electromagnetic energy and distributes it to both the electronic devices (through electrical connection) and the heating heater, merging multiple functions into one component.
3Ease of operation
If the lid is made detachable for easy cleaning, then sanitation is improved, but the reliability of sealing may decrease
Solution Approach 1:
The patent replaces mechanical fastening systems with magnetic attraction for lid attachment. The magnetic force provides reliable sealing while allowing easy detachment without complex mechanical components, combining ease of operation with sealing reliability through a simplified magnetic coupling mechanism.
