Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple filtration layers are used to improve filtration effectiveness, then the removal efficiency of contaminants and microorganisms increases, but the device complexity and pressure drop increase
Solution Approach 1:
The filtration cartridge is divided into multiple functional layers including pre-filter media, central core with water treatment media, and blocking core. Each layer performs a specific filtration function, allowing the system to achieve high removal efficiency for different types of contaminants while maintaining manageable complexity through modular design
Solution Approach 2:
The central core with water treatment media is nested within the pre-filter media, and the blocking core is positioned around the central core. This nested arrangement allows multiple filtration mechanisms to operate simultaneously in a compact structure, improving effectiveness without proportionally increasing overall complexity
2Reliability
If multiple filtration layers are used to improve filtration effectiveness, then the removal efficiency of contaminants and microorganisms increases, but the pressure drop and energy consumption increase
Solution Approach 1:
Different regions of the cartridge have different filtration characteristics tailored to specific needs. The pre-filter media provides coarse filtration with lower resistance, the central core with water treatment media provides targeted treatment, and the blocking core provides fine filtration. This localized optimization reduces overall pressure drop while maintaining high effectiveness
3Productivity
If high pressure is applied to increase filtration rate, then the productivity increases, but the risk of contaminant penetration and system failure increases
Solution Approach 1:
The cartridge is designed with a hierarchical filtration structure where each layer cushions and distributes the pressure load. The pre-filter media captures larger particles first, protecting downstream layers from excessive pressure and contamination. This beforehand cushioning allows the system to operate at high filtration rates without compromising stability or allowing contaminant penetration
