Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current baking oven door designs with non-transparent, insulated doors do not provide adequate visualization of the baking process, limiting user observation and image quality, especially in terms of adjustable fields of view and efficient cooling for image recording devices.
Innovation Solution
A baking oven door with a heat sink on the outer wall for efficient cooling of image recording devices, adjustable actuators for field of view selection, and a glass inner wall with image recording windows, combined with insulation and cooling channels to reduce heat load and improve image quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If a non-transparent, insulated door is used to reduce energy consumption and outer surface temperature, then energy efficiency and user safety are improved, but visualization of the baking process is limited
Solution Approach 1:
The patent uses an image recording device (camera) to capture visual information from the baking chamber and creates a copy of the visual scene that can be displayed on a display unit. This allows users to observe the baking process without needing a transparent door, thereby maintaining the insulated non-transparent door design for energy efficiency while still providing visualization through the copied image signal.
Solution Approach 2:
The patent introduces an intermediary system consisting of an image recording device, signal processing unit, and display unit that mediates between the baking chamber and the user. This intermediary allows indirect observation of the baking process, resolving the contradiction between having an opaque insulated door and being able to visualize the baking process.
2Loss of information
If an image recording device is mounted in the door to visualize the baking chamber, then user observation capability is improved, but the device is exposed to high temperatures reducing its lifespan
Solution Approach 1:
The patent divides the door structure into multiple segments including an inner door portion, outer door portion, and intermediate space. The image recording device is mounted in the intermediate space between the inner and outer door portions, positioning it away from the high-temperature baking chamber while still allowing it to capture images through the transparent inner door portion.
Solution Approach 2:
The transparent inner door portion acts as an intermediary that allows light transmission from the baking chamber to the image recording device while providing thermal isolation. This intermediary element enables the image recording device to capture visual information without being directly exposed to the high-temperature environment, thereby protecting the device and extending its lifespan.
3Measurement precision
If the image recording device is positioned close to the baking chamber for adequate field of view, then image quality is improved, but heat load on the device increases
Solution Approach 1:
The patent segments the door into an inner door portion that is transparent and positioned close to the baking chamber, and an outer door portion that provides thermal protection. The image recording device is positioned in the intermediate space, allowing it to be close enough to the baking chamber to capture adequate images through the transparent inner door portion while being protected from excessive heat by the outer door portion and intermediate space.
