Fire Pit Device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fire pit devices lack a safe and efficient method for moving burning materials without risking user harm due to high thermal conductivity materials and limited control over fire direction.
Innovation Solution
A fire pit device with a handle made from low thermal conductivity material, such as hickory wood, and a head featuring metal hooks and a flat portion for poking and shoveling burning materials, allowing for safe and controlled manipulation of materials within the fire pit.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a fire pit device uses materials with high thermal conductivity to ensure durability and heat resistance, then the device can withstand high temperatures and maintain structural integrity, but the user's hand is at risk of thermal injury from heat transfer along the handle
Solution Approach 1:
The patent introduces a handle made of low thermal conductivity material (such as wood or plastic) as an intermediary between the user's hand and the heat source. This intermediary component has poor thermal conduction properties, blocking the transfer of thermal energy from the burning materials to the user's hand, thus protecting against thermal injury while allowing the device to maintain structural integrity near the fire.
2Adaptability or versatility
If the device head is designed with multiple functional portions (hooks and flat portion) to enable versatile manipulation of burning materials, then the device can perform poking, shoveling, and directing operations, but the device structure becomes more complex
Solution Approach 1:
The patent combines multiple functional elements (first hook portion, second hook portion, and substantially flat portion) into a single integrated device head structure. This merging approach allows the device to perform multiple functions (poking with hooks, shoveling with flat portion, directing flames) without requiring separate tools, thereby achieving versatility while maintaining relatively simple construction.
Solution Approach 2:
The device head is designed with universal functionality to handle various burning materials and perform multiple operations. The hooks can grasp and move logs or coals, while the flat portion can shovel ash or spread burning materials, making the device adaptable to different fire control tasks without requiring specialized tools for each function.
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 easy and safe movement of burning materials, reducing the risk of user injury and improving fire control by using a durable, ergonomic design that maintains a safe distance from the user's hand.
Implementation Method 1
The device handle may be made from a material having a substantially low thermal conductivity

AI summary
A device for moving burning materials around a fire pit includes a device handle and a device head having a first hook portion, a second hook portion and a substantially flat portion. The device handle is preferably made from a wood material, such as hickory wood, and the device head is preferably made from a durable metal material, such as tempered steel. The hook portions of the device are used for poking and moving burning materials (such as wood blocks) around the fire pit; and the substantially flat portion is used for shoveling and moving the burning materials.
