Planar Heating Elements for Uniform Electric Oven Temperature
Here’s PatSnap Eureka !
Summary
Problems
Conventional electric ovens with electric heaters limited in uniform temperature increase within the cavity and face challenges in repair and part exchange due to the heater's fixed position.
Innovation solutions
Incorporation of planar heating elements that extend along one plane, supported by a detachable support member, allowing for radiant heat application to multiple surfaces of the cavity, enhancing temperature uniformity and facilitating easy repair by being easily detachable.
TRIZ Analysis
Specific contradictions:
General conflict description:
Principle concept:
If a conventional electric heater is arranged in one side portion of the cavity, then the heater can be easily installed, but the temperature distribution inside the cavity becomes non-uniform
Why choose this principle:
The heating function is segmented into multiple planar heating elements distributed across different surfaces (top, bottom, side walls) of the cavity. Each heating element independently heats the food from its respective surface, achieving uniform temperature distribution throughout the cavity without requiring a complex centralized heating system.
Principle concept:
If a conventional electric heater is arranged in one side portion of the cavity, then the heater can be easily installed, but the temperature distribution inside the cavity becomes non-uniform
Why choose this principle:
The heating approach transitions from a single-point or single-surface heater to multi-surface planar heating elements. By distributing heating surfaces across top, bottom, and side walls, the system achieves three-dimensional temperature uniformity, effectively solving the non-uniform heating problem caused by conventional single-location heaters.

Abstract
An electric oven includes a top plate and a bottom plate facing each other, two side plates facing each other, and a rear plate connecting the top plate, the bottom plate and the two side plates where the top plate, the bottom plate, the two side plates and the rear plate define a cavity having a front opening, a door which selectively opens and closes the front opening of the cavity, a casing which surrounds the cavity, a support member interposed between the casing and the cavity, and one or more planar heating elements which extend along one plane, are detachably supported by the support member, and apply radiant heat to the cavity.
