Flexible Fire Containment Plate for Low-Labor Stump Burning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Removal of tree stumps is costly and requires significant human involvement.
Innovation Solution
A flexible metallic containment plate is used to encircle a tree stump, with fasteners to secure it in place, and a fuel source is placed between or on top of the stump to facilitate burning, optionally with air holes for oxygen flow, allowing easy and efficient stump removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional stump removal methods are used, then complete stump removal is achieved, but high cost and significant human involvement are required
Solution Approach 1:
The patent replaces traditional mechanical stump removal methods (excavators, stumps grinders) with a thermal combustion system. A fire containment plate concentrates and maintains heat at the stump base, causing the wood to carbonize and burn away through chemical combustion rather than mechanical force, thereby reducing human involvement and operational complexity
Solution Approach 2:
The fire containment plate is designed as a simple, inexpensive, disposable component that can be easily applied and removed after use. This simple device enables complex thermal processing without requiring expensive or complicated equipment, resolving the contradiction between ease of operation and device complexity
2Productivity
If fire containment plate is used, then human labor and costs are reduced, but proper containment and oxygen flow management are required
Solution Approach 1:
The fire containment plate incorporates porous firebrick material that allows controlled oxygen flow through its structure. This porosity provides the necessary oxygen for sustained combustion while maintaining heat concentration and containment, enabling efficient stump burning without requiring complex air delivery systems
Solution Approach 2:
The fire containment plate serves multiple functions simultaneously: it contains heat, provides structured oxygen flow, protects surrounding soil and grass from damage, and maintains fire intensity. This multi-functionality achieves high productivity without increasing device complexity, as a single component performs all necessary operations
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 method reduces human labor and costs associated with stump removal by enabling efficient burning of tree stumps using a flexible containment plate that secures the fuel source and facilitates oxygen flow.
Implementation Method 1
a plurality of air holes (32) spaced along the length (18) and extending from the front (26) to the rear (28)
Implementation Method 2
igniting the fuel source (38) so that the tree stump (12) begins to burn
