Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Conventional outdoor grills lack the ability to easily convert into open fire pits, limiting their versatility and functionality.

Innovation Solution

A convertible grill design that allows the upper body portion to be moved relative to the base, creating a large vertical gap, enabling the grill to transition from a closed grill configuration to an open fire pit configuration by pivoting and stowing covers, thereby altering airflow and usage.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the grill is designed with a fixed enclosed structure, then it maintains structural stability and ease of operation, but it lacks versatility to convert into an open fire pit

Engineering Contradiction:

Improveconversion capability between grill and fire pit modesVSAvoidstructural complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The grill incorporates movable side walls that can be selectively opened or closed, transforming the fixed enclosed structure into a dynamic configuration. This allows the grill to convert between a closed grill mode and an open fire pit mode by simply opening the side walls, providing versatility without requiring complete structural redesign

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The grill structure is designed to serve multiple functions: it can operate as a traditional enclosed grill for cooking, or be converted into an open fire pit for other uses. The same base structure supports both functions through the selective opening/closing of side walls, eliminating the need for separate devices

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If the side walls are made movable to enable conversion, then versatility is improved, but structural stability and ease of operation deteriorate

Engineering Contradiction:

Improveconfiguration flexibilityVSAvoidoperational simplicity

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

The side walls are segmented into movable portions that can be independently opened or closed. This segmentation allows selective opening of only the necessary portions to achieve fire pit configuration while maintaining the enclosed structure when needed, making the conversion process simple and intuitive

Inventive Principle:

Principle #1Segmentation
