Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If the hydrogen peroxide solution is gasified by bringing it into contact with the heating element, then the sterilizer is gasified efficiently, but the stabilizer is deposited and accumulated on the heating element, reducing gasification efficiency
Solution Approach 1:
The patent applies preliminary action by performing cleaning of the heating element at predetermined intervals before stabilizer accumulation significantly degrades performance. The control unit schedules cleaning operations proactively based on operational time or gasification volume, preventing efficiency loss rather than reacting to it after occurrence.
Solution Approach 2:
The system implements self-service through automated cleaning where the cleaning device and control unit automatically perform maintenance without manual intervention. The control unit monitors operational parameters and autonomously activates the cleaning device when cleaning conditions are met, enabling the system to maintain itself.
2Power
If the gasifier is disassembled and cleaned regularly to remove stabilizer deposits, then the gasification efficiency is maintained, but the productivity is reduced
Solution Approach 1:
The patent replaces manual disassembly and cleaning operations with an automated cleaning device that uses water or steam to remove stabilizer deposits. This substitution eliminates the need for production stoppage and manual labor, maintaining gasification efficiency while preserving productivity.
Solution Approach 2:
The system ensures continuity of useful action by performing cleaning operations without interrupting the overall production process. The automated cleaning can occur during low-demand periods or using spare capacity, ensuring that gasification efficiency is maintained while production continues uninterrupted.
3Power
If the stabilizer accumulates on the heating element, then the heat conduction is impeded, but the device complexity increases due to additional cleaning mechanisms
Solution Approach 1:
The cleaning device is designed with multi-functionality, serving both as a water spray system for cleaning and potentially as a pre-treatment step before gasification. The same hardware infrastructure is utilized for multiple purposes, minimizing additional complexity while effectively removing stabilizer deposits to maintain heat conduction.
Solution Approach 2:
The patent introduces water or steam as an intermediary substance that facilitates the removal of stabilizer deposits from the heating element. This intermediary medium enables efficient cleaning without requiring complex mechanical scraping or disassembly mechanisms, simplifying the overall system while maintaining heat conduction efficiency.
