Pivoting Bin-Liner Frame for Wind-Stable Barbecue Grills
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Barbecue grill assemblies often face issues with bin-liners being blown away by strong winds in outdoor environments, causing garbage to be dispersed and creating a mess.
Innovation Solution
A supporting apparatus with two pivotally connected frames is designed to securely hold a bin-liner on a barbecue grill assembly, ensuring it remains in place even in windy conditions by using a combination of lugs, ledges, and buckles to maintain the bin-liner's upper portion in a horizontal position.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a bin-liner is placed on a barbecue grill assembly in an outdoor environment, then garbage can be collected, but strong wind will blow away the bin-liner and disperse garbage
Solution Approach 1:
The patent employs a dynamic frame structure that can pivot between horizontal and vertical positions. The frame is pivotally connected to the barbecue grill assembly, allowing it to adapt its orientation. When in horizontal position, the frame supports the bin-liner against wind forces; when vertical, it facilitates easy removal and disposal of the bin-liner, thus resolving the contradiction between stability during use and ease of disposal.
Solution Approach 2:
The supporting apparatus is divided into multiple components: a frame structure, a supporting unit, and connection mechanisms. The frame itself is segmented into sections that can move relative to each other through pivotal connections. This segmentation allows the system to maintain stability against wind while enabling easy deployment and disposal of the bin-liner.
2Reliability
If a fixed supporting structure is used to hold the bin-liner, then the bin-liner remains stable, but the device becomes more complex
Solution Approach 1:
Instead of a complex fixed supporting structure, the patent uses a dynamic pivotal connection system. The frame is connected to the barbecue grill assembly through pivots that allow simple rotational movement. This dynamic connection provides stability when needed while maintaining structural simplicity, avoiding the need for complex fixed supports, multiple fastening mechanisms, or elaborate anchoring systems.
3Reliability
If the bin-liner is held in a horizontal position, then garbage is contained, but the bin-liner needs to be frequently removed and disposed of
Solution Approach 1:
The pivotal connection allows the frame to be quickly rotated from horizontal to vertical position for bin-liner removal, and back to horizontal for reuse. This dynamic movement is much faster than detaching and reattaching a bin-liner to a fixed structure, significantly reducing the time lost during disposal operations while maintaining effective garbage containment when in horizontal position.
Solution Approach 2:
The frame is pre-positioned in a horizontal orientation ready to support the bin-liner before use. This preliminary positioning eliminates the need for assembly or adjustment when a new bin-liner needs to be installed, allowing quick attachment and immediate garbage containment, thus reducing the time cycle between disposals.

AI summary
Disclosed is an apparatus for holding a bin-liner on a barbecue grill assembly. The apparatus includes a supporting unit and two frames. The supporting unit is connected to the barbecue grill assembly. The first frame is pivotally connected to the barbecue grill assembly. An upper portion of the bin-liner can be flipped and placed on the first frame. The second frame is pivotally connected to the first frame. The first frame is kept in a horizontal position as the second frame is supported on the supporting unit.
