Electric Range Bracket Recess for Heating Unit Wire Clearance
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 not properly secured between the heating unit and the upper plate.
Innovation Solution
A recessed portion is formed on the upper bracket to accommodate the electric wire, preventing interference and ensuring secure mounting of the heating unit, thereby minimizing the risk of disconnection and enhancing electromagnetic compatibility (EMC) and electromagnetic interference (EMI) protection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the electric wire is placed in the space of the heating unit, then the wire can be connected to the temperature sensor, but the wire may be withdrawn from the space and interfere with the heating unit and upper plate when mounted
Solution Approach 1:
The patent divides the mounting structure into segments by creating a dedicated groove in the upper plate for the electric wire. This segmentation isolates the wire from the heating unit's mounting space, allowing the wire to be routed and secured in a separate channel that prevents displacement during assembly.
Solution Approach 2:
The groove acts as an intermediary structure between the electric wire and the upper plate. It provides a dedicated pathway that mediates the wire's position, preventing direct contact with the heating unit while ensuring the wire remains securely connected to the temperature sensor.
2Productivity
If the heating unit is mounted on the upper plate, then the heating unit can function, but pressure may be applied to the electric wire causing disconnection
Solution Approach 1:
The groove segments the mounting area, creating a distinct channel for the electric wire that is separated from the heating unit's contact area with the upper plate. This ensures that the pressure from mounting the heating unit is directed only to the heating unit itself, not to the wire.
Solution Approach 2:
The groove introduces a dimensional solution by creating a subsurface channel rather than attempting to manage wire positioning in the same plane as the heating unit mounting. This vertical dimensionality change allows the wire to be protected beneath the surface level of the upper plate.
3Ease of operation
If the electric wire is disposed on the close contact portion, then the wire may be easily connected, but the wire interferes with the heating unit and upper plate causing operational errors and fire hazards
Solution Approach 1:
The patent extracts the electric wire from the dangerous close-contact area between the heating unit and upper plate by routing it through a groove. This removal from the harmful zone eliminates the risk of the wire being compressed, disconnected, or causing fire hazards while maintaining its electrical connection function.
Solution Approach 2:
The groove, which initially appears as merely a structural feature, is converted into a protective element that benefits the wire by providing mechanical protection and proper routing. The structure that defines the upper plate's geometry becomes the solution that prevents harm to the wire.

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.
