Cooktop Window Sealing Structure With Heat-Shielding End Plate
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cooking appliances face challenges in achieving a reliable and precise sealing between the window and base plate, particularly when exposed to heat from cooking utensils, leading to potential damage and impaired display quality due to fragile connections and high costs associated with heat-resistant silicone joints.
Innovation Solution
A cooking appliance design featuring a synthetic material seal between the base plate and window, protected by a flange with a higher solid-to-viscous transformation point than the seal material, ensuring heat resistance and precise positioning, and using a flange to shield the seal from heat sources.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a seal made of synthetic material is used between the window and base plate, then the sealing function is achieved, but the seal is damaged by heat from cooking utensils
Solution Approach 1:
A flange made of heat-resistant material is introduced as an intermediary element between the window and the base plate. This flange serves as a protective barrier that shields the synthetic material seal from direct contact with hot cooking utensils, while the seal continues to perform its sealing function between the window and the flange or base plate.
Solution Approach 2:
The connection structure is divided into separate functional elements: the flange provides heat resistance and structural support, while the seal provides the sealing function. This segmentation allows each component to be optimized for its specific function - the flange for heat resistance and the seal for sealing - rather than requiring a single material to perform both functions simultaneously.
2Adaptability or versatility
If a permanently elastic connection is used between the window and base plate, then flexibility is provided, but the connection is fragile and the window can move during use
Solution Approach 1:
The connection system uses a composite structure combining a rigid flange made of heat-resistant material with a flexible seal made of synthetic material. The rigid flange provides structural stability and prevents window movement, while the flexible seal maintains the necessary elasticity for sealing and accommodates thermal expansion or contraction.
3Object-affected harmful factors
If heat-resistant silicone joint is used between base plate and window, then heat resistance is achieved, but the manufacturing process becomes expensive and difficult to implement in large quantities
Solution Approach 1:
The heat-resistant function is separated from the sealing function. The flange made of heat-resistant material handles the heat resistance requirement, while the seal made of less expensive synthetic material handles the sealing function. This allows the use of cheaper materials for the seal while maintaining heat resistance through the flange structure, simplifying the manufacturing process.
Solution Approach 2:
The flange acts as an intermediary that protects the seal from heat exposure. This allows the seal to be made from less expensive synthetic materials that would otherwise be damaged by heat, while the flange absorbs the thermal stress and protects the sealant joint from direct heat contact.

Implementation Method 1
a flange (66, 66') of a material different from that of the seal (6) covering at least part of the outer surface of the seal (6) located between the outer surface (21) of the base plate (2) and the outer surface (51) of the window (5)
Implementation Method 2
a seal (6) of synthetic material located between a part of the edge (20) of the base plate (2) and a part of the edge (50) of the window (5) to allow sealing between the window (5) and the base plate (2) vis-à-vis the outside
