Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If conventional chemical additives (barium nitrate, sodium nitrate) are used to enhance ignition performance, then ignition efficiency is improved, but toxic gas emissions and heavy metal content increase
Solution Approach 1:
The patent removes harmful chemical additives (barium nitrate, sodium nitrate) from the ignition coal formulation, extracting only the essential carbonized wood components and natural adhesives, thereby eliminating the source of toxic gas emissions and heavy metal contamination while maintaining ignition functionality through optimized wood chip composition
Solution Approach 2:
The patent changes the chemical composition parameters by replacing synthetic combustion accelerators with naturally occurring compounds found in wood (lignin, cellulose, hemicellulose), and adjusts the carbonization degree and moisture content parameters to achieve optimal ignition performance without chemical additives
2Strength
If chemical adhesives are used to bind wood chips, then molding strength is improved, but toxic gas emissions increase
Solution Approach 1:
The patent uses inexpensive, naturally occurring wood components (lignin, cellulose, hemicellulose) that decompose completely during carbonization and combustion, replacing persistent chemical adhesives with biodegradable, non-toxic natural binders that provide sufficient binding strength without emitting harmful substances
Solution Approach 2:
The patent changes the adhesive composition from synthetic chemicals to natural wood polymers, and adjusts the bonding parameters through controlled carbonization temperature and pressure to achieve adequate molding strength using only natural adhesives present in the wood material
3Quantity of substance
If unclear wood sources are used for manufacturing, then material availability is improved, but heavy metal contamination increases
Solution Approach 1:
The patent implements preliminary quality control measures by establishing clear specifications for wood source selection before manufacturing begins, requiring documentation of wood origin and pre-screening for contamination, thereby preventing heavy metal-laden materials from entering the production process
Solution Approach 2:
The patent changes the material selection criteria by introducing strict purity parameters and origin verification requirements, shifting from accepting any available wood material to selectively using only verified clean wood sources that meet specific contamination thresholds
4Quantity of substance
If carbonization is performed to create ignition coal, then fuel density is improved, but toxic gas generation during combustion increases
Solution Approach 1:
The patent optimizes the carbonization parameters by controlling temperature, time, and atmosphere to achieve the desired fuel density and ignition properties while minimizing the formation of toxic compounds, maintaining carbon content within a specific range that balances energy density with combustion cleanliness
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 process significantly reduces toxic gas emissions, particularly carbon monoxide, and eliminates hazardous heavy metals, improving ignition efficiency and safety, while promoting sustainable forest resource management and preventing misuse for suicidal purposes.
Implementation Method 1
carbonization of raw materials is used. The agglomerated wood charcoal is produced through a phenomenon and a process in which organic substances are heated and pyrolyzed in an anaerobic atmosphere (or low-oxygen atmosphere) blocking air and oxygen
Implementation Method 2
applying a drying oil, which is a natural combustion material, on an outer surface of the molded and dried ignition coal and then drying

AI summary
A method of manufacturing toxic gas reducing environmentally friendly ignition coal includes the steps of: chipping wood to a predetermined size or less by using an industrial chipping machine; heat treating the woody material obtained after the chipping step for a predetermined time at a processing temperature of 150 °C to 400 °C so that the carbon content of the woody material is 55 wt% or more and less than 80 wt%; pulverizing the woody material that has undergone the heat treating step into a pulverizer to then be pulverized into a wood powder; agitating the heat-treated wood powder with a natural adhesive, to then inject the agitated wood powder into a mold or a mold press; and compression molding and drying the molded wood powder, thereby reducing toxic gas generation.
