Electric Range Segmented Base Plate Design to Prevent Sagging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electric ranges face the issue of sagging base plates due to the weight of heating units, which affects the stability and heat distribution, and require additional support to prevent sagging and improve strength.
Innovation Solution
The use of multiple divided base plates with bent ends, either in a Z shape or inverse Z shape, and reinforcement beams to stabilize the base plates and prevent sagging, allowing for effective heat delivery and easy installation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single base plate is used to support heating units, then the structure is simple, but the base plate sags due to the weight of the heating units
Solution Approach 1:
The single base plate is divided into multiple base plates (first base plate, second base plate, third base plate, etc.) arranged side by side. Each base plate supports heating units independently, distributing the weight load and preventing sagging while maintaining overall structural simplicity.
2Strength
If multiple divided base plates are used to prevent sagging, then the base plate strength is improved, but the device complexity increases
Solution Approach 1:
Multiple base plates are arranged side by side to form a unified support structure that collectively supports the heating units. The base plates work together as an integrated system, providing enhanced strength without requiring complex individual components or additional support structures.
3Strength
If reinforcement structures are added to prevent sagging, then the base plate strength is improved, but the manufacturing complexity increases
Solution Approach 1:
Instead of manufacturing a single large base plate with complex reinforcement structures, the design segments the base plate into multiple simpler plates. Each plate has a straightforward structure that is easier to manufacture, and they are assembled together to achieve the required strength without complex reinforcement elements.

Implementation Method 1
In a resistance heating method, electric current is supplied to a metallic resistance wire or a non-metallic heat generation element such as silicon carbide to generate heat
Implementation Method 2
In an induction heating method, high-frequency power is supplied to a coil to generate a magnetic field around the coil, and eddy current produced in the generated magnetic field is used to heat an object to be heated made of a metallic material
