Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If traditional methods like landfill or cremation are used to handle animal carcasses, then the carcasses can be disposed of, but environmental pollution (air, water, soil) occurs and energy consumption increases
Solution Approach 1:
The patent changes the temperature parameter from high-temperature cremation to controlled low-temperature fermentation (maintaining 35-45°C through heating elements), transforming the disposal method from thermal destruction to biological decomposition, thereby reducing energy consumption and environmental pollution
Solution Approach 2:
The patent replaces the mechanical/thermal system of cremation with a biological fermentation system using microorganisms to decompose carcasses, substituting high-energy combustion with low-energy biological processes that produce organic fertilizer instead of pollution
2Productivity
If high-temperature biodegradation method is used to treat animal carcasses, then organic fertilizer can be produced, but energy consumption is very high and centralized control cannot be achieved
Solution Approach 1:
The patent changes the temperature parameter from high-temperature processing to controlled low-temperature fermentation (35-45°C), maintaining productivity through extended fermentation time while dramatically reducing energy consumption through efficient heating elements and insulation
Solution Approach 2:
The patent introduces rotation capability to the fermentation tank, allowing dynamic adjustment of carcass position and improving fermentation efficiency without requiring high temperatures, thereby maintaining organic fertilizer production while reducing energy input
3Extent of automation
If multiple fermentation tanks are integrated into one centralized system, then centralized control is achieved and cost is reduced, but device complexity increases
Solution Approach 1:
The patent designs multiple fermentation tanks with identical structures and control interfaces, allowing a single centralized controller to manage all tanks uniformly. Each tank can independently process different carcasses while sharing common control, heating, and monitoring systems, reducing overall system complexity through standardization
Solution Approach 2:
The patent divides the large-scale fermentation system into multiple independent but identical tank modules, each capable of independent operation. This modular segmentation allows centralized control through replication of simple identical units rather than managing one complex heterogeneous system
