Double-Wall Electric Kettle Window Sealing for Heat Insulation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electric kettles face issues with heat insulation performance, power consumption, user convenience due to lack of visibility into the heating body, and complex assembly processes, particularly with double-wall structures and window sealing.
Innovation Solution
A double-walled electric kettle design featuring a cylindrical body with a heat insulation space between inner and outer bodies, a mounting port for a window, and a window gasket for sealing, allowing for improved heat insulation, reduced power consumption, and enhanced user convenience by enabling internal state visibility and simplified assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If a double-layer vacuum structure is used to improve heat insulation performance, then heat insulation performance is improved, but the inside of the body becomes difficult to check
Solution Approach 1:
The body is segmented into an inner body and an outer body with a heat insulation space between them. The window is specifically installed on the inner body, separating the insulation function (double-layer structure) from the observation function (window), thus resolving the contradiction between heat insulation and visibility.
2Ease of operation
If a window is formed in a double wall structure to enable internal visibility, then user convenience is improved, but the sealing structure becomes difficult to implement and assembly becomes difficult
Solution Approach 1:
The window is extracted as a separate component that is installed only on the inner body, not on the double wall structure itself. This simplifies the sealing requirement to a single location (inner body window) rather than requiring complex sealing through the entire double wall structure, thus improving ease of assembly while maintaining user convenience.
3Reliability
If the main body is made of stainless steel to improve hygiene and durability, then hygiene and durability are improved, but the temperature of the main body rises when water boils causing burns
Solution Approach 1:
The body is divided into an inner body (stainless steel for hygiene and durability) and an outer body (separated by heat insulation space). This segmentation allows the inner body to maintain its hygienic and durable properties while the outer body remains cool to the touch, eliminating the burn risk associated with stainless steel bodies.
4Ease of manufacture
If a plastic material is used for the main body to facilitate internal structure arrangement, then ease of manufacturing is improved, but harmful components may be dissolved in hot water and the kettle is vulnerable to scratches
Solution Approach 1:
The body is segmented into an inner body made of stainless steel (for hygiene and scratch resistance) and an outer body that can be made of plastic (for ease of manufacturing and structural arrangement). This segmentation allows each material to be used where it is most appropriate, combining the advantages of both materials while avoiding their disadvantages.

AI summary
An electric kettle includes a body (10) made of a metal material, formed by an outer body (11) and an inner body (12) having a cylindrical shape with an opened upper surface and an opened lower surface, wherein a heat insulation space (102) is formed between the outer body (11) and the inner body (12), a heating module (50) configured to form a bottom of a space (101) in which water is contained inside the body and heat the water, a mounting port (116) opened to pass through the outer body (11) and the inner body (12), a window (13) made of a transparent material and mounted on the mounting port (116) to see through an inside of the body (10), and a window gasket (135) disposed along a circumference of the window (13) to seal a gap between the inner body (12) and the window (13). The window (13) is doubly sealed in contact with the outer body (11) and the window gasket (135).
