Foldable Grill Chamber Structure for Single-Person Portability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing grilling apparatuses designed for whole animals or BBQs require at least two persons for transport, setup, and operation due to heavy components, making them cumbersome for single individuals.
Innovation Solution
A foldable and portable grilling apparatus with lightweight components, featuring a body with foldable side walls, a movable top lid, and a tray that can be converted into a compact size, allowing single-person operation and transport, along with intake and exhaust apertures for efficient cooking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If heavy components are used for manual or electronic rotation of food, then cooking functionality is improved, but portability and ease of transport deteriorate
Solution Approach 1:
The grilling apparatus is divided into multiple separable components including a body, lid, tray, and side walls that can be folded independently. This segmentation allows each component to be lightweight yet functional, resolving the contradiction between having sufficient cooking functionality and maintaining portability.
Solution Approach 2:
The side walls are designed to be convertible between unfolded and folded relationships, transforming the apparatus from a compact portable state to an expanded operational state. This dynamic transformation allows the device to be lightweight for transport yet provide full cooking functionality when in use.
2Adaptability or versatility
If the grilling apparatus is designed for whole animal roasting, then cooking versatility is improved, but device complexity and setup difficulty worsen
Solution Approach 1:
The grilling apparatus is designed to accommodate multiple cooking functions including whole animal roasting, conventional BBQ, and other grilling applications. The versatile design incorporates features like removable trays, foldable side walls, and adjustable configurations that enable different cooking methods without requiring separate specialized equipment for each function.
Solution Approach 2:
The apparatus uses separable components including removable trays and foldable side walls that simplify setup and configuration for different cooking types. This segmentation allows users to easily adjust the apparatus for various cooking versatility needs without complex assembly procedures.
3Weight of moving object
If lightweight components are used, then portability is improved, but structural strength and stability deteriorate
Solution Approach 1:
The side walls are designed with convertible mechanisms that provide structural strength when unfolded for cooking while maintaining lightweight construction for portability. The dynamic transformation between folded and unfolded states allows the same components to serve both weight reduction and structural support functions.
Solution Approach 2:
The apparatus employs composite construction combining lightweight materials with sufficient structural strength. The body, lid, and side walls are designed to be lightweight yet maintain the necessary strength for cooking operations, resolving the contradiction between portability and structural integrity.
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 ease of setup, operation, and transport by a single individual while maintaining efficient cooking capabilities, as the apparatus can be easily converted between operational and compact configurations.
Implementation Method 1
intake apertures defined through a lower end portion of each of the opposite side walls for enabling entry of air from exterior of the body into the grilling chamber
Implementation Method 2
exhaust apertures defined through an upper end portion of each of the opposite side walls for venting gaseous products of combustion from the grilling chamber
Implementation Method 3
a plurality of upright corner leg members each mounted at one of a pair of opposite edge portions of a respective one of the front and back walls so as to support the body spaced above a support surface

AI summary
A foldable and portable grilling unit includes a body and a plurality of upright corner leg members which together support the body spaced above a support surface. The body has front and back walls and opposite side walls extending between them so as to form a grilling chamber when the body is in an erected operational configuration. The side walls each are formed by a pair of panels, inner hinged connections between the panels of each pair, and outer hinged connections of the panels of each pair to the front and back walls. The panels of each side wall may be folded to convert the body to a compacted portable configuration in which it may be transported in a container sleeve by a user.
