Grill Hinge Assembly with Removable Lid Bracket for Easy Disassembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing grill hinges do not allow for easy removal and reinstallation of the lid from the base, making initial assembly difficult and limiting the use of accessories that require lid removal, such as rotisserie accessories.
Innovation Solution
A hinge assembly comprising a stationary bowl bracket, a pivoting middle bracket, and a removable lid bracket that can be secured to the middle bracket using a spring-assisted mechanism, allowing for safe and convenient removal and reinstallation of the lid, with features like a stop to limit lid opening and a keyhole-shaped lid lock slot for secure attachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the lid is hinged to the bowl using known hinges, then the lid is securely attached to the bowl, but the lid cannot be easily removed or is only removable by complicated disassembly
Solution Approach 1:
The hinge assembly is divided into three separate brackets: a bowl bracket attached to the bowl, a middle bracket that pivots on the bowl bracket, and a lid bracket attached to the lid. This segmentation allows the lid bracket to be independently removed from the middle bracket, enabling easy lid removal without complicated disassembly of the entire hinge system.
Solution Approach 2:
The middle bracket serves as an intermediary component between the bowl bracket and the lid bracket. It provides a removable connection point where the lid bracket can be attached and detached, facilitating easy lid removal while maintaining secure attachment when closed.
2Adaptability or versatility
If the lid is made removable from the bowl, then accessories like rotisserie accessories can be used, but the initial assembly becomes difficult
Solution Approach 1:
The bowl bracket and middle bracket are pre-assembled and attached to the bowl before the lid bracket is installed. This preliminary assembly creates a ready-made hinge structure that simplifies the final attachment of the lid bracket, making both initial assembly and future removals easy operations.
3Ease of operation
If a spring-assisted mechanism is added to assist lid opening, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The spring mechanism is integrated into the hinge assembly to automatically assist lid opening without requiring additional external components or complex control systems. The spring provides mechanical assistance that reduces the effort needed by the user, while the overall mechanism remains relatively simple in design.
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
Enables easy and safe removal and reinstallation of the grill lid, facilitating the use of accessories and improving the assembly process while maintaining the advantages of known hinges.
Implementation Method 1
In addition, at least one spring may be provided, the spring connected at one end to a spring flange on the bowl bracket and the other end connected to a spring flange on the middle bracket, the spring assisting in opening the lid.
