Barbecue Grill Coupling Structure for Fast Secure Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional barbecue grills with gas supply devices are bulky and inconvenient to connect and disconnect manually, requiring cumbersome screwing mechanisms that complicate quick and safe assembly.
Innovation Solution
A connecting structure comprising a grilling device, a base with multiple coupling assemblies, each including a holder with a joining element and a positioning piece, allowing for quick and secure attachment through a combination of circular head and extension retention, along with elastic pieces for enhanced stability and ease of disassembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual screwing mechanisms are used to connect the barbecue grill, then structural integrity is maintained, but assembly time and operational complexity increase
Solution Approach 1:
The connecting structure is divided into modular components: holders attached to the base and positioning pieces with grooves for the grill components. This segmentation allows each part to be independently manufactured and assembled, enabling quick connection without complex screwing mechanisms while maintaining structural integrity through the interlocking holder-positioning piece design.
Solution Approach 2:
The holder and positioning piece act as intermediary elements that facilitate quick connection between the base and grill components. The positioning piece with its groove structure serves as a mediator that receives and secures the joining element of the holder, enabling rapid assembly without direct screwing while ensuring reliable structural connection.
2Reliability
If manual screwing mechanisms are used to connect the barbecue grill, then secure attachment is achieved, but ease of operation deteriorates
Solution Approach 1:
The positioning piece's groove structure is designed to automatically engage with the holder's joining element when components are brought together. This self-service mechanism eliminates the need for manual screwing operations, allowing users to simply align and press components together for secure attachment, dramatically improving ease of operation while maintaining reliable connection.
Solution Approach 2:
The holder and positioning piece serve as intermediary components that simplify the connection process. The groove in the positioning piece acts as a guide and securing mechanism that automatically engages with the joining element, replacing complex manual screwing operations with a simple snap-fit action that is both easy to operate and secure.
3Adaptability or versatility
If conventional gas supply devices are used, then functional requirements are met, but device size and storage convenience worsen
Solution Approach 1:
The gas supply system is segmented into compact, modular components that can be easily stored and transported. The base structure with integrated holders and the grill components are designed as separate but compatible modules, reducing overall device volume when not in use while maintaining full functional capabilities when assembled.
Solution Approach 2:
The connecting structure enables dynamic assembly and disassembly of the barbecue grill components. The holder and positioning piece mechanism allows the grill to be quickly configured when needed and easily stored in a compact state when not in use, adapting between functional and storage states without compromising functionality.
