Solution Overview

Problem

Existing multi-functional outdoor cooking devices, such as fire pits, grills, and smokers, face challenges due to space limitations, storage issues, and cost concerns, leading consumers to prefer single-use options rather than versatile solutions that can convert between functions without tools.

Innovation Solution

A convertible fire pit, grill, griddle, smoker, and table apparatus that allows users to easily switch between functions using a bowl, ring, grate, grill frame, and hood, with features like rotating grill frames, interchangeable grill components, and a shelf system, enabling conversion without tools.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If consumers own multiple separate devices (fire pit, grill, smoker), then each device can be optimized for its specific function, but space requirements and storage issues increase

Engineering Contradiction:
Improvefunctional versatilityVSAvoidspace occupation
Core Design Contradiction:
Adaptability or versatilityVSArea of stationary object

Solution Approach 1:

The patent implements a universal base structure that can accommodate multiple different cooking components (grill grates, smoker boxes, griddle surfaces, fire pit configurations). The standardized base unit with interchangeable components allows a single device to perform the functions of multiple separate devices, directly reducing space requirements while maintaining functional versatility.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The cooking system is divided into modular components that can be independently selected and assembled. Different cooking surfaces and attachments can be swapped on a single base, allowing users to configure the device for specific cooking tasks without needing separate dedicated equipment for each function.

Inventive Principle:
Principle #1Segmentation

2Adaptability or versatility

If consumers purchase multiple separate devices, then each device can be optimized for its specific use, but cost increases

Engineering Contradiction:
Improvefunctional versatilityVSAvoidtotal device quantity
Core Design Contradiction:
Adaptability or versatilityVSQuantity of substance

Solution Approach 1:

By designing a single base unit that can support multiple cooking components, the patent reduces the total quantity of devices needed from three separate purchases (fire pit, grill, smoker) to one versatile system, directly addressing cost concerns while maintaining all desired functions.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Adaptability or versatility

If consumers take multiple cooking devices camping, then each device provides its specific function, but transport space limitations prevent bringing all three

Engineering Contradiction:
Improvefunctional versatilityVSAvoidtransport volume
Core Design Contradiction:
Adaptability or versatilityVSVolume of moving object

Solution Approach 1:

The modular design allows components to be nested or stacked within the base structure during transport. The interchangeable components can be stored inside or attached to the base unit, significantly reducing the volume required for transportation compared to three separate bulk devices.

Inventive Principle:
Principle #7Nested doll (Nesting)

4Area of stationary object

If a single device is designed to perform multiple functions, then space and cost are reduced, but device complexity increases

Engineering Contradiction:
Improvespace occupationVSAvoidstructural complexity
Core Design Contradiction:
Area of stationary objectVSDevice complexity

Solution Approach 1:

The complexity is managed through segmentation into a simple standardized base unit and separate specialized components. This modular approach allows each component to remain relatively simple in design while the system as a whole provides multiple functions, reducing the complexity burden on any single part.

Inventive Principle:
Principle #1Segmentation

AI summary

Systems and methods for providing a convertible fire pit, grill, griddle, smoker and table apparatus are provided. The apparatus is configured such that a user can readily, easily, and safely convert the apparatus between a fire pit, a grill, and a smoker without tools. The apparatus may include a bowl, a grill frame support, e.g., a ring, positionable about the bowl, a shelf attachable to the grill frame support, a grate positionable within the bowl, and a grill frame positionable about grill frame support. The grill frame may be configured to rotate about the bearings within the grill frame support. The apparatus may also include interchangeable grill components positionable about the grill frame and a hood disposed above the grill frame.
