Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing grill lighters require lengthy heating times, are cumbersome to handle, and pose safety risks due to smothered flames, flare-ups, and uneven ember distribution, leading to patient exhaustion and potential physical harm.
Innovation Solution
A fuel comprising charcoal and charcoal ignition components, such as combustible materials with a flash point above 55°C, that ignites safely and evenly distributes heat across the charcoal layer without additional charcoal application, reducing ignition time and eliminating flare-up risks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If cube-shaped grill lighters are used and charcoal is added after lighting, then the flames are smothered, but the heating process must be extended by re-lighting and adding more charcoal
Solution Approach 1:
The patent combines charcoal and ignition components into a single integrated fuel product. The ignition components are embedded within the charcoal matrix, allowing simultaneous ignition and combustion without requiring separate lighting steps or additional charcoal addition, thus eliminating the time loss associated with smothered flames and re-ignition attempts
Solution Approach 2:
The ignition components are pre-integrated into the charcoal structure during manufacturing. This preliminary preparation ensures that when the fuel is applied to the grill, ignition occurs immediately and reliably without requiring subsequent procedural steps to restart or extend the heating process
2Productivity
If liquid or gel-like grill lighters are poured on charcoal, then they can blaze up like flashes of flame, but this poses safety risks to the grill operator
Solution Approach 1:
The patent changes the physical state and compositional parameters of the ignition system by using solid ignition components embedded in charcoal rather than liquid or gel accelerants. This parameter change eliminates the flash-point-related flare-up risks associated with liquid lighters while maintaining rapid ignition capability through the built-in ignition components
Solution Approach 2:
The patent converts the potential harm of flammable liquids into a benefit by using controlled ignition components that ignite safely without causing dangerous flare-ups. The ignition components are designed to burn controllably, transforming the risky rapid combustion of liquids into a safe, gradual ignition process that protects the operator
3Ease of operation
If liquid grill lighters are applied to charcoal layer, then only the uppermost pieces of charcoal come into contact with the lighter, but the lower-lying charcoal pieces do not ignite
Solution Approach 1:
The patent merges the ignition function throughout the entire charcoal structure by embedding ignition components within the charcoal matrix itself. This ensures that both uppermost and lower-lying charcoal pieces contain ignition sources, eliminating the penetration problem of liquid lighters and ensuring complete ignition of the entire charcoal layer
Solution Approach 2:
The patent applies local quality by distributing ignition components throughout different regions of the charcoal structure - including upper, middle, and lower layers. This ensures that every portion of the charcoal, regardless of depth or position, has ignition capability, solving the problem of incomplete ignition caused by liquid lighter penetration limits
4Reliability
If multiple process steps are used for lighting charcoal, then the handling becomes cumbersome, but the heating time increases significantly
Solution Approach 1:
The patent combines multiple separate lighting steps into a single application of integrated fuel. The charcoal and ignition components are pre-combined in one product, eliminating the need for separate charcoal addition and lighting steps, thus simplifying the procedure while maintaining reliable ignition
Solution Approach 2:
The ignition components are pre-positioned within the charcoal structure during manufacturing. This preliminary arrangement eliminates the need for subsequent manual ignition attempts and procedural adjustments, reducing complexity to a single straightforward application and ignition step
