Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If conventional cleaning methods are used for storage tanks, then the cleaning process is simple, but residues remain and contamination occurs
Solution Approach 1:
The cleaning system is segmented into multiple functional units: solvent supply unit, inert gas supply unit, circulation pump, and detector. Each unit performs a specific function in the cleaning process, allowing for precise control and monitoring while maintaining modular simplicity
Solution Approach 2:
An inert gas is introduced as an intermediary substance to facilitate the cleaning process. The inert gas mixes with the solvent to create a cleaning mixture that effectively removes residues without causing contamination, and the inert atmosphere prevents oxidation of sensitive stored materials
2Manufacturing precision
If multiple cleaning agents are used to remove residues, then cleaning effectiveness improves, but the risk of contamination increases
Solution Approach 1:
The system maintains an inert atmosphere throughout the cleaning process by supplying inert gas to the storage tank. This inert environment prevents oxidation and contamination of both the stored material and the cleaning agents, allowing effective residue removal without introducing harmful contaminants
Solution Approach 2:
A detector is installed to monitor the cleaning process in real-time, detecting the presence of residues and the state of the cleaning agents. This feedback mechanism allows the system to adjust cleaning parameters dynamically, ensuring thorough residue removal while preventing over-cleaning or contamination
3Manufacturing precision
If the storage tank is cleaned thoroughly, then purity of stored material is maintained, but cleaning time increases
Solution Approach 1:
The cleaning process operates continuously with the circulation pump maintaining constant flow of the cleaning mixture through the storage tank. The inert gas continuously supplies fresh solvent and removes contaminated liquid, ensuring thorough cleaning without requiring multiple discrete cleaning cycles
Solution Approach 2:
The inert gas serves as a mediator that accelerates the cleaning process by enhancing mass transfer between the solvent and residues. The gas bubbles through the cleaning mixture, increasing contact between solvent and residues, which speeds up residue removal while maintaining purity standards
