Fire Enclosure with Movable Wind Shield for Adaptable Wind Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing outdoor fire structures, such as fire pits, often fail to effectively shield fires from wind, making them unsuitable for residential settings where wind protection is necessary.
Innovation Solution
A modular fire enclosure with a movable wind shield that mounts to a base, allowing dynamic repositioning to accommodate changing wind directions, combined with a spark screen for containment and airflow, and an optional annular flange for secure mounting, ensuring effective wind protection and airflow.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a fixed wind shield is used in fire enclosures, then wind protection is provided, but adaptability to changing wind directions is lost
Solution Approach 1:
The wind shield is designed with movable components that allow it to rotate and adjust its orientation relative to the fire pit. This dynamic capability enables the shield to adapt to changing wind directions while maintaining effective wind protection, resolving the contradiction between fixed protection and adaptability.
2Adaptability or versatility
If a movable wind shield is added to provide adaptability, then adaptability to wind direction is improved, but device complexity increases
Solution Approach 1:
The wind shield is divided into multiple segments or panels that can move independently or in coordinated fashion. This segmentation allows the shield to achieve adaptability through simpler mechanical means compared to a fully movable single structure, reducing overall device complexity while maintaining functionality.
3Device complexity
If traditional fire pits without wind shields are used, then device complexity is low, but wind protection is insufficient
Solution Approach 1:
The wind shield structure is designed to perform multiple functions: it provides wind protection, allows for adjustable orientation to adapt to different wind conditions, and can be integrated with the fire pit in a relatively simple manner. This multi-functionality addresses the need for wind protection without proportionally increasing complexity.

AI summary
A representative enclosure includes: a base defining an interior configured to receive combustible materials, the base having an aperture defining an opening, which communicates with the interior, the opening being configured to receive therethrough the combustible materials; a spark screen configured to prevent access to the interior via the opening when in a closed position in which the spark screen engages the base, the spark screen being further configured to permit a flow of air into and out of the interior; and a wind shield, mounted to the base, having a shield portion extending upwardly from the base and disposed exterior to the spark screen, the shield portion being movable relative to the base.
