Built-In Grill Firebox Support Frame With Ventilated Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional barbecue grill support systems, both portable and fixed, face limitations in providing adequate support and ventilation for built-in gas barbecue grill fireboxes, often relying on transverse members that may not fully address structural integrity and heat management needs.
Innovation Solution
A support assembly comprising a frame assembly with side and back panels, a bottom shelf, and venting systems, including door access and multiple vent apertures, that securely mounts the firebox to a work structure while facilitating heat and air ventilation, enhancing structural support and heat management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If conventional transverse members are used to support the firebox, then the structure is simple to manufacture, but the structural integrity and heat management are insufficient
Solution Approach 1:
The frame assembly is divided into multiple vertical frame members (first, second, third, and fourth vertical frame members) positioned at different locations, each providing localized support. This segmentation allows the structure to achieve greater structural integrity through distributed support points rather than relying on a few transverse members, while maintaining manufacturing simplicity through modular construction.
Solution Approach 2:
The support structure transitions from relying primarily on horizontal transverse members to incorporating multiple vertical frame members that extend from the base to the firebox. This dimensional change from horizontal to vertical orientation provides superior structural support and heat management by creating a more rigid three-dimensional framework that better resists thermal and mechanical loads.
2Reliability
If the firebox rests on transverse members along its entire width, then the support coverage is comprehensive, but ventilation and heat management are compromised
Solution Approach 1:
The continuous support along the firebox width is segmented into discrete support points provided by individual vertical frame members. The firebox rests on these separated vertical members rather than a continuous transverse member, creating gaps that allow ventilation airflow to pass beneath and around the firebox, thereby managing heat accumulation while maintaining stable support.
Solution Approach 2:
Different regions of the frame assembly have different functions: vertical frame members provide localized support points for the firebox, while the spaces between them provide ventilation pathways. This local differentiation allows simultaneous achievement of stable support where needed and heat dissipation where required, resolving the contradiction between support comprehensiveness and ventilation effectiveness.
3Strength
If more vertical frame members are added to improve support, then structural integrity increases, but device complexity increases
Solution Approach 1:
The vertical frame members serve multiple functions simultaneously: they provide structural support for the firebox, create ventilation channels between them, define the boundaries of the cooking chamber, and support various grill components. This multi-functionality allows the use of multiple vertical members to enhance structural integrity without proportionally increasing device complexity, as each member contributes to multiple system requirements.
