Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If flame-based cremation is used to dispose bodies, then the cremation process is efficient and widely accepted, but it releases significant carbon dioxide into the atmosphere causing environmental harm
Solution Approach 1:
The patent replaces the thermal/chemical combustion process (flame-based cremation) with a biological decomposition process using insect larvae. Instead of using fire to cremate bodies, the system employs black soldier fly larvae that naturally decompose organic matter, substituting a mechanical/thermal system with a biological one to eliminate carbon dioxide emissions while maintaining body disposal functionality
Solution Approach 2:
The patent changes the fundamental parameter of the cremation process from high-temperature combustion to controlled biological decomposition at lower temperatures. By adjusting the environmental parameters (temperature, humidity, oxygen levels) within the enclosure to suit the larvae's needs, the system achieves effective body decomposition without the harmful emissions associated with flame-based methods
2Object-generated harmful factors
If insect larvae are used to decompose bodies, then carbon dioxide emission is reduced, but the decomposition process takes longer than flame-based cremation
Solution Approach 1:
The patent applies preliminary action by introducing insect larvae that have already been conditioned and are ready for decomposition at the start of the process. The system prepares the enclosure environment in advance with appropriate temperature, humidity, and oxygen levels to immediately support larval activity, maximizing decomposition efficiency from the beginning without requiring gradual conditioning periods
Solution Approach 2:
The patent optimizes decomposition speed by carefully controlling environmental parameters within the enclosure. By maintaining specific temperature ranges, humidity levels, and oxygen concentrations that are ideal for black soldier fly larvae, the system accelerates the biological decomposition process to complete body disposal within a practical timeframe while still avoiding carbon dioxide emissions
3Productivity
If an enclosure with controlled environment is used for larval decomposition, then decomposition efficiency is improved, but device complexity increases due to air conditioner and monitoring systems
Solution Approach 1:
The patent applies multi-functionality by designing the air conditioner to simultaneously perform multiple tasks: controlling temperature for larval comfort, managing humidity levels, and regulating oxygen concentration. This single device handles multiple environmental parameters that would otherwise require separate control systems, reducing overall system complexity while maintaining high decomposition efficiency
Solution Approach 2:
The system incorporates self-service features through automated monitoring and control mechanisms. Sensors continuously monitor environmental parameters and trigger air conditioner operation only when adjustments are needed, allowing the system to self-regulate without constant human intervention. This automation reduces operational complexity while ensuring optimal decomposition conditions are maintained
