Self-locking telescopic fire pit
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing outdoor grills and fire pits are unstable, difficult to transport, and often result in messy setup and teardown, with issues of instability during transport and exposure to freezing temperatures.
Innovation Solution
A self-locking telescopic fire pit design featuring double-walled sections that telescope for easy storage and use, with air flow through cavities for clean burning, and locking mechanisms for stability in both extended and retracted positions, allowing it to be easily transported and used as a cooking grill or emergency stove.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a traditional grill is used for outdoor cooking, then cooking functionality is provided, but the grill becomes unstable and falls over during transport
Solution Approach 1:
The fire pit is designed with telescopic walls that nest within each other when collapsed, allowing the structure to compact into a small, stable form that fits within vehicle contours and prevents falling over during transport
2Adaptability or versatility
If a grill is set up and taken down repeatedly, then cooking is enabled, but the setup process becomes messy and soils the vehicle
Solution Approach 1:
The fire pit utilizes flexible, fire-resistant fabric walls that can be easily rolled up and stored without creating mess, eliminating the soil and debris problems associated with traditional metal grill teardown
Solution Approach 2:
The fire pit is divided into collapsible sections that can be independently folded and stored, allowing for clean, organized storage without messy disassembly
3Weight of moving object
If the fire pit walls are thin for lightweight portability, then transport ease is improved, but animals may get injured if they touch the outer walls when burning
Solution Approach 1:
The fire pit incorporates an outer protective wall that acts as an intermediary barrier between the fire and animals, providing thermal insulation and physical protection while maintaining the lightweight structure
4Volume of moving object
If the fire pit is designed to collapse flat for storage, then transport space is reduced, but the structure may flip over during vehicle transport
Solution Approach 1:
The fire pit design incorporates a low-profile, flat collapsing configuration that distributes weight evenly and creates a stable, wide base when stored in vehicles, preventing flipping while maintaining compact volume
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
The solution provides a lightweight, stable, and clean-burning fire pit that can be easily transported and stored, preventing mess and injury, while maintaining stability during use and transport, and serving as a versatile cooking and heating solution for outdoor and tactical applications.
Implementation Method 1
The double walls of the present invention allow air to flow inward from the bottom and the top of the self-locking telescopic fire pit. The air intake allows the present invention to provide a clean burn.
