Projector Reflector Cooking Information Display Induction Cooktop
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Induction heating cooking apparatuses lack an effective method to display cooking information to users in a manner that is easily recognizable from below the top plate, limiting user interaction and feedback.
Innovation Solution
Incorporating a projector and reflector system within the apparatus, where the projector outputs cooking information to a reflector positioned between the working coil and the projector, allowing this information to be projected or reflected onto the top plate for user visibility, while the control panel displays different information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If cooking information is displayed only on the control panel, then the device structure remains simple, but user recognition of cooking information from below the top plate is insufficient
Solution Approach 1:
The patent introduces a new display dimension by projecting cooking information onto the top plate surface, allowing users to view information from below the top plate. This transforms the traditional control panel display into a multi-dimensional information presentation system, solving the visibility problem without significantly increasing overall device complexity
Solution Approach 2:
The reflector acts as an intermediary component between the projector and the top plate, enabling the projection of cooking information onto the top plate surface. This intermediary element facilitates information transmission from the projector through the reflector to the visible area on the top plate, enhancing user recognition
2Ease of operation
If a projector and reflector system is added to display information on the top plate, then user recognition of cooking information is improved, but the device complexity increases
Solution Approach 1:
The top plate serves multiple functions: it acts as both the cooking surface and the display surface for cooking information. By utilizing the existing top plate structure for dual purposes, the system enhances user interaction without adding separate display hardware, thereby limiting the increase in device complexity
Solution Approach 2:
The patent merges the display function with the existing top plate structure by projecting information onto it. This consolidation combines the cooking surface and information display surface into a single element, improving ease of operation while avoiding the need for separate display components that would increase device complexity
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables users to easily recognize cooking information from below the top plate through the projector and reflector system, enhancing user interaction and feedback, and providing a distinct display of information on the control panel.
Implementation Method 1
A coil (or working coil) that generates a magnetic field by a current applied below a metal cooking container (e.g., pot, etc.) may be positioned. A secondary current is induced in the metal cooking container by the magnetic field generated in the coil.
Implementation Method 2
Induction heating is a method of converting electrical energy into heat energy by electromagnetic induction and heating the food.
Implementation Method 3
The induced secondary current causes food ingredients to be heated and cooked using Joule's heat generated in the metal cooking container.
Implementation Method 4
a reflector positioned between the working coil and the projector, and configured to receive the cooking information
