Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing grill hinges for outdoor ovens have complex structures with numerous parts, leading to low transmission efficiency, premature spring fatigue, and high assembly costs due to excessive compression of springs, resulting in a short lifespan and inefficient opening-and-closing mechanisms.
Innovation Solution
A grill damping hinge design featuring a C-shaped hinge with overlapping covers, arcuate grooves, and dual spring shafts for enhanced strength and adjustability, allowing for secure connection and adjustable angles, reducing the complexity of assembly and improving sealing and safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional spring hinge structure with fixed housing and movable housing is used, then the opening-and-closing function is achieved, but the structure becomes complex with many parts and complicated positioning
Solution Approach 1:
The patent merges the fixed housing and movable housing into a single integrated hinge body structure. The hinge body includes a hinge axis and hinge arm that work together as one piece, eliminating the need for separate fixed and movable housings and their associated positioning accessories. This integration directly reduces the number of parts while maintaining the opening-and-closing function.
Solution Approach 2:
The hinge body is designed to perform multiple functions: it provides the hinge axis for rotation, supports the spring mechanism for damping, and includes the hinge arm for connection. This multi-functional design eliminates the need for separate components that would otherwise be required to perform these individual functions, thereby reducing overall structural complexity.
2Ease of operation
If traditional transmission structure with many parts is used, then the opening-and-closing function is achieved, but the transmission efficiency becomes low
Solution Approach 1:
The hinge arm is directly integrated with the hinge axis, creating a rigid connection that eliminates intermediate transmission parts. When the hinge arm rotates, it directly drives the opening-and-closing motion without energy loss through multiple transmission interfaces. This direct coupling significantly improves transmission efficiency.
3Stability of the object's composition
If spring is always in compressed state to maintain stable closed position, then the stopping function is achieved, but the spring force is lost and spring life becomes short
Solution Approach 1:
The spring pre-compression amount is made adjustable rather than fixed, allowing the system to adapt to different operating conditions. The hinge body includes an adjusting hole through which the spring can be repositioned to change its initial compression state. This dynamic adjustability allows optimization between stability and spring life based on actual usage requirements.
Solution Approach 2:
The patent allows changing the spring pre-compression parameter by adjusting the spring's position relative to the hinge arm through the adjusting hole. This parameter change enables the spring to operate in different compression states, preventing continuous high compression that would lead to premature spring failure while still maintaining adequate stability.
4Strength
If complex positioning accessories are used to assemble large parts with small parts, then the structural integrity is achieved, but the processing steps become complicated and assembly cost increases
Solution Approach 1:
The hinge body is designed as an integrated structure where the hinge axis, hinge arm, and spring mounting features are all part of a single component or pre-assembled unit. This eliminates the need for multiple small positioning accessories to assemble large parts, as the integrated design inherently provides structural integrity without requiring complex fastening systems.

AI summary
Disclosed is a grill damping hinge comprising a hinge lower cover and a hinge upper cover covering the top of the hinge lower cover. The invention can adopt double-axis double spring pressing design, and the hinge ear can be adjusted back and forth, and can be easily adjusted when the oven body and the oven cover are different in size, to ensure the sealing effect. The upper cover of the invention is lighter during opening and closing, and the opening-and-closing of the oven cover can stay at any angle within 0 to 58°, thereby avoiding the natural falling of the oven cover and having higher safety performance; In the production process of the invention, the cumbersome link of the screws and the nuts in the traditional hinge is avoided, and the manual installation and commissioning cost can be greatly saved.
