Solution Overview
Problem
Existing cooking appliances face challenges in optimizing the positioning of light sources within the cooking chamber, particularly in terms of thermal stress, mechanical protection, and space utilization, while also ensuring effective illumination and information display.
Innovation Solution
The light source is positioned outside the cooking chamber, specifically in front of the muffle's front edge, connected to a carrier that serves as both a mechanical stabilization element and a reflector, allowing for improved thermal insulation and protection, with the option to use multiple light sources of different spectral ranges for enhanced illumination and information display.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If the light source is positioned inside the cooking chamber, then illumination effectiveness is improved, but thermal stress on the light source increases
Solution Approach 1:
The light source is extracted from the cooking chamber and positioned outside, specifically in front of the front edge of the muffle. This separation removes the light source from the high-temperature environment while maintaining its illumination function through strategic positioning and optical design.
2Object-affected harmful factors
If the light source is positioned outside the cooking chamber, then thermal stress is reduced, but illumination effectiveness decreases
Solution Approach 1:
A carrier structure serves as an intermediary between the light source and the cooking chamber. This carrier positions the light source optimally outside the muffle while providing mechanical support and stabilization, enabling effective illumination without direct thermal exposure.
Solution Approach 2:
The illumination function is achieved by positioning the light source in a different spatial dimension (outside the cooking chamber) rather than within it. The carrier structure enables this dimensional transition while maintaining functional effectiveness through proper optical positioning.
3Area of stationary object
If the light source is positioned in front of the muffle front edge, then space utilization is optimized, but mechanical protection is reduced
Solution Approach 1:
The carrier acts as a protective intermediary structure that houses and secures the light source in the exposed position in front of the muffle. This carrier provides mechanical protection while enabling the space-optimized positioning outside the cooking chamber.
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
This configuration minimizes thermal stress on the light source, provides mechanical protection, optimizes space usage, and ensures effective illumination of the cooking chamber and information display, even when the door is closed, while allowing for precise and adaptive lighting based on the door's position and food support status.
Implementation Method 1
The carrier also has at least one reflector for reflecting the light from the light source into the door closing the cooking chamber
