Cooktop Window Sealing With Heat-Shield End Plate
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cooktop designs face issues with sealing between the window and base plate, particularly due to heat damage from cookware, and difficulty in precise positioning and securing the display screen, which affects the perception of high-resolution screen displays.
Innovation Solution
A cooktop design featuring a synthetic material seal between the base plate and window, with an end plate made of a material with a higher transformation point than the seal to provide heat resistance and protection, and mechanical means for precise positioning and securing of the display screen.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a seal made of synthetic material is used between the window and base plate, then sealing is achieved, but the seal is damaged by heat from cookware positioned close to or on it
Solution Approach 1:
An end plate is introduced as an intermediary element between the window and the base plate, positioned to protect the seal from direct heat exposure. The end plate has a higher transformation point than the seal material, allowing it to withstand higher temperatures and shield the seal from thermal damage while maintaining the sealing function.
Solution Approach 2:
The invention changes the material parameter (transformation point) by selecting an end plate material with a higher transformation point than the seal material. This parameter change enables the end plate to resist higher temperatures and protect the seal from heat damage, resolving the contradiction between achieving sealing and preventing heat damage.
2Stability of the object's composition
If the screen is secured to the casing, then the screen is fixed, but it is difficult to precisely position and secure the screen with respect to the window in all three dimensions of space
Solution Approach 1:
The connection structure is segmented into multiple functional elements: the end plate provides a mounting surface, the seal provides positioning references, and the screen is secured to these elements. This segmentation allows for precise positioning in all three dimensions while maintaining stable fixation, as each segment can be independently designed and adjusted for its specific function.

AI summary
A cooktop for a fixed or mobile cooking appliance, including a base plate, at least a part, or all, of a peripheral outer edge of a window being in the plane of a peripheral outer edge of the base plate, at least one end plate which is made of different material than that of a seal and is disposed above or on the seal, at least a part of an outer surface of the seal which is located between an outer surface of the base plate and an outer surface of the window being covered by the end plate.
