Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If conventional drying installations are used, then drying of organic matter is achieved, but the installations are large and unsuitable for compact spaces
Solution Approach 1:
The patent combines multiple functions (mixing, heating, vacuum extraction, condensation) into a single integrated installation. The mixer housing serves as both the mixing chamber and the heating chamber, while the vacuum pump and condenser are integrated into the same system, eliminating the need for separate large-scale installations and achieving compact design without sacrificing drying efficiency
Solution Approach 2:
The installation performs multiple functions simultaneously: the heating device heats both the mixer housing and the organic matter, the vacuum pump serves both to create vacuum for odorless processing and to extract moisture, and the condenser condenses both the extracted air and the evaporated moisture. This multi-functionality allows a compact design to achieve the productivity of larger specialized installations
2Object-generated harmful factors
If organic waste is collected in containers for days or weeks, then disposal is simplified, but foul smells are liberated and hygienic conditions deteriorate
Solution Approach 1:
The patent creates a vacuum environment in the sealed mixer housing, replacing air with vacuum conditions. This prevents aerobic decomposition and odor generation by microorganisms. The extracted air is condensed and removed, maintaining the vacuum and ensuring odorless processing throughout the drying period, thus eliminating the harmful smell effect while maintaining hygienic conditions
Solution Approach 2:
The vacuum pump continuously extracts air and evaporated moisture from the sealed mixer housing. By removing the air environment that enables odor generation and decomposition, the system prevents harmful factors from arising during the entire processing period, allowing waste to be held and processed without the hygienic deterioration that occurs in conventional container storage
3Device complexity
If complex sterilization processes are used, then waste disposal is enabled, but the process becomes complicated and time-consuming
Solution Approach 1:
The patent changes the fundamental parameter of the processing environment from atmospheric pressure to vacuum conditions. This parameter change eliminates the need for complex sterilization processes, as the vacuum environment inherently prevents microbial growth and decomposition. The simple heating and vacuum extraction process replaces complex sterilization procedures, reducing both device complexity and processing time
