Electric Range Bracket Recessed Design to Prevent Wire Disconnection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional induction heating-type electric ranges face issues with electric wire disconnection due to pressure from the heating unit, leading to operational errors and potential fire hazards when the wire is withdrawn from the mounting space and comes into contact with the heating unit and upper plate.
Innovation Solution
The electric range incorporates a recessed portion on the upper bracket to accommodate the electric wire, preventing interference between the wire and the heating unit, and enhances the bracket's rigidity with a bent edge, thereby minimizing electromagnetic interference and improving manufacturing convenience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the electric wire is disposed in the partially empty space of the heating unit, then the manufacturing process is simplified, but the electric wire may be withdrawn and interfere with the heating unit and upper plate causing disconnection
Solution Approach 1:
The patent divides the bracket into multiple parts: the main bracket body and a separate wire retaining structure. This segmentation allows the electric wire to be securely held in a dedicated space, preventing it from being withdrawn and interfering with the heating unit, while maintaining ease of assembly during manufacturing
Solution Approach 2:
The patent introduces a wire retaining structure as an intermediary element between the electric wire and the heating unit. This intermediary component prevents direct contact and potential interference between the wire and heating unit, while still allowing the wire to be properly positioned and connected during manufacturing
2Stability of the object's composition
If the heating unit is mounted in close contact with the upper plate, then the structural stability is improved, but pressure is applied to the electric wire causing disconnection
Solution Approach 1:
The patent applies local quality by creating a specific region in the bracket with reduced density or modified structural properties where the electric wire is positioned. This local modification reduces pressure concentration on the wire while maintaining the overall structural stability and close contact between the heating unit and upper plate
3Device complexity
If the electric wire is disposed on the close contact portion between the heating unit and upper plate, then the wire routing is simplified, but the wire interferes with the heating unit and upper plate leading to operational errors and fire hazards
Solution Approach 1:
The patent extracts the electric wire from the potentially harmful close contact portion between the heating unit and upper plate. By providing a dedicated wire routing channel or retaining structure, the wire is taken out from the dangerous zone, eliminating the risk of interference and fire hazards while maintaining simplified wire routing through the bracket structure

Implementation Method 1
In the induction heating method, high-frequency power is applied to a coil to generate a magnetic field around the coil, and an eddy current generated in the generated magnetic field is used to heat an object to be heated made of a metallic material.
Implementation Method 2
an eddy current generated in the generated magnetic field is used to heat an object to be heated

AI summary
An electric range is provided, in which a portion of a bracket, which is configured to support at least one heating unit, is bent downward. More specifically, the at least one heating unit may be mounted in a specific region on the bracket, and a recessed portion which is downwardly formed may be formed in a portion of the specific region. Accordingly, an electric wire disposed between the at least one heating unit and the bracket may be accommodated or disposed in the recessed portion, so that interference between the electric wire disposed between the at least one heating unit and the bracket and the at least one heating unit may be prevented.
