Oven Door Hinge Damping Layout for Simpler Soft Closing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing oven hinge apparatuses have complex structures that increase manufacturing costs and reduce productivity, and are difficult to apply to various oven types due to internal space constraints and complicated internal arrangements of damping components.
Innovation Solution
A hinge apparatus with a damping unit installed outside the hinge body, directly contacting the rotary hinge lever to reduce door closing speed and noise, featuring a damper case filled with oil and a shaft that protrudes to interact with the hinge lever, allowing for simplified assembly and design flexibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the damping means is connected to the hinge shaft inside the housing, then the door can be slowly closed, but the structure becomes very complicated and manufacturing cost increases
Solution Approach 1:
The damping unit is extracted from the internal housing structure and relocated to the outer surface of the hinge body. The damping lever extends outward from the hinge body to contact the damping unit, separating the damping function from the complex internal housing arrangement. This extraction simplifies the overall structure while maintaining the door slowing function.
Solution Approach 2:
The damping unit is positioned in a different spatial dimension - on the outer surface of the hinge body rather than inside the housing. The damping lever rotates in an extended space beyond the hinge body, creating a more open and simpler structural arrangement compared to the confined internal positioning.
2Reliability
If the roller, guide member and damper member are accommodated inside the housing, then the door can be controlled, but the internal structure of the housing becomes complicated and manufacturing cost increases
Solution Approach 1:
The damping unit is extracted from the housing interior and positioned on the outer surface of the hinge body. This eliminates the need for complex internal housing structures to accommodate damping components, thereby simplifying manufacturing processes and reducing costs while preserving door control functionality.
3Reliability
If the damping unit is installed inside the hinge body, then the door closing speed can be controlled, but the installation space is restricted and it is difficult to apply to various oven types
Solution Approach 1:
The damping unit is extracted from the constrained internal space and positioned on the outer surface of the hinge body. This provides sufficient installation space and allows the hinge apparatus to be adapted to various oven types and sizes without being limited by internal space restrictions.
Solution Approach 2:
By positioning the damping unit on the outer surface rather than inside the hinge body, the design utilizes external space that is not constrained by the internal dimensions of different oven types. This dimensional change enables broader adaptability across various oven configurations.
4Productivity
If the damping unit is installed outside the hinge body, then the structure is simplified and productivity is enhanced, but the damping unit must be positioned within the radius of rotation of the hinge lever
Solution Approach 1:
The damping lever is designed to rotate dynamically around the hinge pin, with its endpoint contacting the damping unit at specific positions during the rotation arc. The damping unit is positioned within the rotation radius, and the lever naturally interacts with it during door closing, providing damping without requiring complex positioning mechanisms.

Function Achieved in This Case
The solution enhances productivity by simplifying the hinge apparatus structure, reduces noise and improves user safety by controlling the door's closing speed, and allows for easy adaptation to different oven sizes and types without requiring internal space modifications.
Implementation Method 1
a damping unit which is installed at an outer surface of the hinge body within a radius of rotation of the hinge lever, and is in contact with the hinge lever to reduce a rotating speed of the hinge lever when the hinge lever is rotated
