Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fire-starting methods are time-consuming, difficult, and often require multiple attempts, especially in wet conditions, and single-use fire starters are inefficient and expensive, while smokeless firepits produce excess smoke during the initial stages of fire ignition.
Innovation Solution
A reusable fire starter with a non-porous, high-temperature, heat-resistant material receptacle that holds a flammable substance, allowing for efficient ignition and sustained combustion of standard firewood logs, even in smokeless firepits, and can be refilled for multiple uses.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If single-use fire starters are used, then fire ignition is achieved, but they are consumed and require frequent replacement, increasing cost and waste
Solution Approach 1:
The fire starter device separates the consumable fuel component from the reusable structural component. After the fuel is consumed, the metal container and internal components are recovered and can be refilled with new fuel, eliminating the need to discard the entire device. This resolves the contradiction by maintaining ignition reliability while reducing substance loss through component recovery.
Solution Approach 2:
The invention replaces expensive single-use fire starters with a durable reusable container and separate inexpensive consumable fuel cartridges. The reusable metal container can be used indefinitely, while only the fuel cartridges need replacement. This resolves the contradiction by making the consumable portion cheaper and easier to replace while maintaining overall system reliability.
2Speed
If flammable liquids are poured on firewood logs, then rapid combustion occurs, but the flame is difficult to control and requires frequent fuel replenishment
Solution Approach 1:
The fire starter device introduces a controlled intermediary mechanism between the user and the firewood. The fuel is contained in a metal container with controlled release through a screen or mesh, allowing the flame to be generated and sustained without direct pouring. This resolves the contradiction by maintaining rapid combustion while improving ease of operation through controlled fuel delivery.
Solution Approach 2:
The invention changes the physical state and delivery method of the flammable liquid. Instead of pouring liquid directly onto logs, the fuel is contained and released through a controlled mechanism that regulates the rate and distribution of fuel delivery. This resolves the contradiction by maintaining combustion speed while improving fire control through parameter management of fuel delivery.
3Reliability
If a small flame is built gradually from tinder and kindling, then a self-sustaining fire is achieved, but the process is time-consuming and requires multiple steps
Solution Approach 1:
The fire starter device performs preliminary preparation of the fuel in a concentrated, ready-to-burn form within the metal container. The fuel is pre-saturated and contained in a configuration that promotes immediate and sustained combustion when ignited. This resolves the contradiction by eliminating the time-consuming steps of gathering and arranging tinder and kindling, while reliably achieving self-sustaining fire.
Solution Approach 2:
The invention merges the functions of multiple fire-building components (tinder, kindling, accelerant) into a single integrated device. The metal container holds a combination of fuel materials that work together to provide immediate ignition and sustained burning. This resolves the contradiction by reducing the multi-step process to a single action of igniting the pre-prepared fuel mixture, saving time while maintaining reliability.
4Object-generated harmful factors
If smokeless firepits are used, then smoke production is minimized, but excess smoke is produced during the initial ignition stages
Solution Approach 1:
The fire starter device uses a fuel composition and delivery mechanism that promotes complete and rapid combustion from the start. The fuel is designed to burn hot and clean, providing strong oxidation that minimizes the production of smoke and incomplete combustion products. This resolves the contradiction by reducing smoke production during the critical initial ignition phase, allowing smokeless firepits to achieve clean burn faster.
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 reusable fire starter quickly and efficiently ignites and sustains a fire, reducing the time and effort required, minimizing smoke production, and eliminating the need for frequent fuel replenishment.
Implementation Method 1
The burn chamber (15) can be configured to hold a flammable substance that, when lit, produces a flame that can be distributed underneath one or more logs to assist with starting a fire
Data Source
AI summary
A reusable fire starter is disclosed. The reusable fire starter may include a receptable with at least three legs and an open-top burn chamber configured to receive and hold a flammable substance that, when ignited, can be used to easily and quickly start a self-sustaining fire using standard firewood logs with little effort and without building up a gradual fire from smaller kindling or tinder first. The receptacle can be comprised of a non-porous, heat-resistant material that survives being used to start a fire, so the reusable fire starter can be reused to start subsequent fires after being refilled with more of the flammable substance. A method of use of the reusable fire starter is also disclosed herein.
