Oven Door Hinge Mounting Member for Secure Heat-Sealing Closure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing oven door assembly technologies fail to ensure a secure and proper fixation of the hinge body to the oven body, leading to incomplete closure and subsequent heat and energy loss due to a weak connection, particularly exacerbated by enameled front walls that cannot be shaped desirably.
Innovation Solution
A right-triangular mounting member is fixed to both the base and front wall, providing a secure assembly for the hinge body, with features like support members, embossment-shaped protrusions, and steps to align and fix the hinge body correctly, ensuring full closure and stability against various forces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Weight of moving object
If the hinge body is fixed directly to the enameled front wall, then the door weight can be reduced, but the connection becomes weak and insecure
Solution Approach 1:
The patent introduces a mounting member as an intermediary component between the hinge body and the enameled front wall. This mounting member provides a secure attachment point that overcomes the weakness of directly fixing to the enameled surface, while still allowing for reduced door weight by maintaining a simplified hinge structure.
2Loss of energy
If the hinge body is fixed securely to the body, then the door can be fully closed preventing heat loss, but the assembly complexity increases
Solution Approach 1:
The patent combines the mounting function and the fixing function into a single integrated mounting member. This merging of functions allows the hinge body to be securely attached to ensure full door closure and prevent heat loss, while avoiding the need for separate complex assembly steps.
3Shape
If the front wall is enameled for aesthetic purposes, then the appearance is improved, but the hinge body cannot be securely fixed
Solution Approach 1:
The mounting member serves as an intermediary that bridges the aesthetic enameled front wall and the functional requirement for strong fixation. It allows the enameled surface to maintain its appearance while providing a secure attachment mechanism for the hinge body through alternative fixation methods.

AI summary
The oven (1) of the present invention comprises a cooking chamber (2) wherein foods to be cooked are disposed, a body (3) that has a ceiling, a base (6), a rear wall, a frame-shaped front wall (4) and two side walls (5), all of which surround the cooking chamber (2), and that is formed by joining the base (6), ceiling, rear wall (not illustrated in the figures), front and side walls (4 and 5); an opening (7) which is located on the front wall (4) and which allows access to the cooking chamber (2), a door (8) which is opened by rotating around the horizontal axis and which provides the opening (7) to be closed, two housings (12) which are located on both sides of the front wall (4), and two hinges (9) that have a hinge body (10) passing through the housing (12) and a hinge arm (11), one end of which is fixed to the hinge body (10) and the other end to the door (8), and that provide the door (8) to be opened and closed as a result of the movement of the hinge body (10) and the hinge arm (11) with respect to each other.
