Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If large reverse osmosis plants are used to provide purified water in home settings, then water purification quality is improved, but system size and infrastructure requirements worsen
Solution Approach 1:
The water purification system is divided into multiple smaller filtration stages (reverse osmosis membrane, ultrafiltration membrane, activated carbon filters) that can be arranged in series. Each stage handles a specific aspect of purification, allowing the system to achieve high purification quality without requiring a single large processing unit, thus reducing overall system footprint for home use
Solution Approach 2:
The patent employs nested filtration where smaller filtration elements are contained within larger housing structures. The reverse osmosis membrane is housed within a pressure vessel that is integrated into the larger purification system. This nested arrangement maximizes the use of space and allows compact configuration of multiple filtration stages in a space-efficient manner
2Reliability
If complex treatment systems are implemented to ensure patient safety and treatment efficacy, then treatment reliability is improved, but system complexity and maintenance requirements worsen
Solution Approach 1:
The system incorporates multiple sensors that continuously monitor treatment parameters (pressure, temperature, flow rate, conductivity) and provide feedback to the control unit. This automated feedback mechanism ensures patient safety by detecting anomalies and adjusting operations in real-time, while reducing the need for complex manual monitoring systems and simplifying maintenance through automated diagnostics
Solution Approach 2:
The control unit automatically manages system operations based on sensor feedback, performing self-diagnosis and self-adjustment to maintain safe treatment conditions. This automation reduces the complexity of operator intervention required while maintaining high reliability through consistent automated safety checks and protocol enforcement
3Manufacturing precision
If precise proportioning systems are used to mix medicaments with accurate solute concentrations, then medicament mixing precision is improved, but device complexity and training requirements worsen
Solution Approach 1:
The system replaces manual proportioning operations with automated electronic control. Flow meters and pumps are controlled by a microprocessor-based control unit that calculates and adjusts flow rates to achieve precise medicament concentrations. This substitution of mechanical manual operations with automated electronic systems maintains high mixing precision while reducing the complexity of user interaction and training requirements
4Productivity
If continuous proportioning systems are deployed for medicament preparation, then medicament production efficiency is improved, but water consumption and drainage requirements worsen
Solution Approach 1:
The system maintains continuous operation of the reverse osmosis and ultrafiltration membranes during medicament preparation, ensuring that purified water is continuously available for mixing. This continuous operation eliminates the need for batch processing and repeated purification cycles, improving medicament production efficiency while optimizing water usage through sustained membrane operation at steady state
Solution Approach 2:
The system recovers and reuses purified water that contacts the medicament concentrate but does not undergo complete dialysis. This recovered water is redirected back into the purification stream or used for non-critical dilution purposes, reducing overall water consumption while maintaining continuous medicament production capability
