Oven Door Control Panel Wiring for Larger Cooking Cavity Space
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cooking apparatuses with control panels built into the door often have large input/display devices that occupy valuable space and detract from the usable area, increasing the overall size of the appliance.
Innovation Solution
The control panel is integrated into the door, with a wire guide structure that securely routes the connecting wire through the door, allowing for a more compact design and unobstructed view into the cooking cavity, while protecting electronic components from heat and microwaves.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the control panel is built into the door with a large input/display device, then the control functionality is improved, but the usable space of the cooking cavity is reduced and the overall size of the appliance increases
Solution Approach 1:
The control panel is extracted from the main body of the cooking apparatus and integrated into the door assembly. This separation allows the control device to be positioned outside the cooking cavity, eliminating the space occupation problem while maintaining full control functionality. The wire guide structure facilitates this extraction by providing a dedicated routing path for electrical connections.
Solution Approach 2:
The control panel is relocated from the vertical dimension (inside the cavity depth) to the horizontal dimension (on the door surface). This dimensional shift moves the control device out of the cooking cavity's usable volume while preserving accessibility, effectively resolving the space conflict through spatial reconfiguration.
2Volume of stationary object
If the control panel is built into the door, then the overall size of the appliance is reduced, but the wire routing becomes complex and may interfere with other components
Solution Approach 1:
A wire guide structure is introduced as an intermediary component between the control panel and the main body. This dedicated guide structure provides a predetermined routing path for wires, simplifying the routing process and preventing interference with other door components such as the hinge and handle. The wire guide acts as a mediator that organizes and protects the electrical connections.
Solution Approach 2:
The wire routing path is segmented into distinct sections: a wire guide opening in the door, a wire guide structure within the opening, and a predetermined routing path. This segmentation allows for organized wire management, making installation and maintenance easier while reducing complexity compared to ad-hoc routing methods.
3Shape
If the control panel is integrated into the door, then the aesthetics are improved, but the electronic components are exposed to heat and microwaves
Solution Approach 1:
The electronic components of the control panel are extracted from the cooking cavity environment and relocated to the door assembly. This extraction removes the components from the harmful thermal and electromagnetic field, protecting them from damage while maintaining the integrated aesthetic appearance achieved through door integration.
Solution Approach 2:
The wire guide structure serves as a protective intermediary that channels electrical connections through a controlled path away from the cooking cavity. This intermediary routing protects the wires and connected components from exposure to heat and microwaves while maintaining the aesthetic integration of the control panel in the door.

AI summary
A cooking apparatus is provided. The cooking apparatus includes a cooking cavity, an upper space formed above the cooking cavity, lateral side spaces formed to at opposite lateral sides of the cooking cavity, a rear space formed behind the cooking cavity, and a lower space formed below the cooking cavity. A fan provided in the rear space generates a cooling flow that cools components housed in the rear space. A cooling flow path extends from the rear space and into the upper space and lateral side spaces. Flow from the upper space enters the door to cool the door and is exhausted through a lower portion of the door. Flow from the lateral side spaces, which includes an exhaust flow from the cooking cavity, is guided to the lower space and exhausted. In this manner, the cooking apparatus can be completely cooled and cooking odors and heat appropriately exhausted by the cooling fan positioned in the rear space.
