Ventilated Oven Door Assembly for Cooler Outer Surfaces
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing oven doors lack effective ventilation and ease of assembly, maintenance, and cleaning, leading to potential overheating and safety issues, especially for children, and are not designed to efficiently cool the outer surface.
Innovation Solution
An oven door design featuring a detachable connection system with snapping means and integrated ventilation openings that connect to the oven's air suction area, allowing ambient air to cool the outer surface and facilitate easy assembly, maintenance, and cleaning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the door is designed with a solid structure to ensure strength and stability, then the door frame strength is improved, but the outer surface temperature increases and cooling efficiency deteriorates
Solution Approach 1:
The door is divided into multiple separate components: an outer door part, an inner door part, and a door frame. These segments are connected through detachable connection means, allowing each part to be optimized independently. The outer door part can be designed for strength while the inner door part and frame are optimized for cooling through integrated ventilation openings.
Solution Approach 2:
Different parts of the door have different structural properties optimized for their specific functions. The outer door part maintains structural strength, while the inner door part and door frame incorporate ventilation openings for cooling. The connection means are designed with snapping elements that provide both mechanical strength and allow for thermal expansion/contraction.
2Stability of the object's composition
If the door parts are permanently connected to ensure structural stability, then the door frame strength is improved, but the ease of assembly, maintenance, and cleaning deteriorates
Solution Approach 1:
The connection system transitions from a permanent static connection to a dynamic detachable connection. The snapping means allow the inner door part to be easily attached and detached from the outer door part and frame, enabling flexible assembly, disassembly for cleaning, and maintenance while maintaining structural stability when assembled.
Solution Approach 2:
The inner door part is extracted as a separate, removable component from the overall door assembly. This allows the inner door part to be easily removed for cleaning or replacement without disassembling the entire door structure, while the outer door part and frame remain permanently connected for structural stability.
3Temperature
If the door is designed with integrated ventilation openings for cooling, then the cooling efficiency is improved, but the device complexity increases
Solution Approach 1:
The ventilation openings are merged into the inner door part and door frame as integrated features rather than separate components. This combining of cooling function with existing structural elements achieves effective door cooling without significantly increasing overall device complexity. The snapping connection system is also integrated into the frame structure.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The design effectively cools the oven door's outer surface using ambient air, enhances ventilation, and simplifies production, maintenance, and cleaning by allowing easy disassembly and reassembly without compromising airflow or structural stability.
Implementation Method 1
at least one unit is provided with at least one opening for ventilation, which is connected in a closed position of the door to an air suction area of the oven... the ambient air cooling the outer surface of the door
