Telescopic Fire Pit with Nested Ring Collapse for Portable Camping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing outdoor cooking and fire pit solutions are cumbersome, unstable, and dirty during transport, and fail to provide a safe and portable solution for camping in varying temperatures.
Innovation Solution
A collapsible fire pit with a telescopic mechanism using L-shaped guides and pins, designed to collapse into a compact form for easy transport and storage, featuring a ring base and multiple annular rings for stability and safety, made from rigid fireproof materials, and incorporating features like an elevated ash pan and air flow apertures.
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 structure transitions from a static, rigid form to a dynamic, collapsible form. The telescopic rings can be extended to provide stability during use and collapsed to prevent falling over during transport, adapting the structural state based on operational requirements
Solution Approach 2:
The fire pit rings are designed to nest within each other when collapsed, with each ring containing the previous ring. This nesting mechanism reduces the overall footprint and prevents the structure from falling over during transport while maintaining full functionality when deployed
2Ease of operation
If a traditional grill is disassembled for transport, then transport ease is improved, but the user and vehicle become filthy during the process
Solution Approach 1:
The fire pit is segmented into multiple telescopic rings that can independently collapse and nest within each other. This segmentation allows the structure to compact without requiring complete disassembly, eliminating the soiling problem while maintaining transport ease
Solution Approach 2:
The fire pit incorporates a flexible mesh screen that can be folded and stored within the collapsed structure. This flexible component allows the fire pit to compact neatly without exposing loose parts that could cause soiling during transport
3Ease of operation
If a fire pit is made collapsible for easy transport, then transport ease is improved, but the structural complexity increases
Solution Approach 1:
The telescopic rings serve multiple functions: they provide the structural framework for the fire pit, enable the collapsing mechanism for compact storage, and offer stability when deployed. This multi-functionality reduces the need for separate components, simplifying the overall structure despite the collapsible feature
Solution Approach 2:
The nesting design of the telescopic rings creates a self-contained collapse mechanism where each ring naturally guides the others into position. This self-guiding nesting reduces the need for complex locking mechanisms or additional fastening components, keeping the device relatively simple
