Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If disposable plastic bags for saline solution are used, then fluid delivery is simplified, but waste generation increases and disposal costs rise
Solution Approach 1:
The patent replaces disposable plastic bags with a reusable purification station that can be disassembled and transported. The system uses durable components (purification filters, storage tanks, pumps) that can be cleaned and reused multiple times, eliminating the need for continuous disposal of single-use bags while maintaining ease of fluid delivery through the same portable operation capability.
Solution Approach 2:
The system recovers and reuses water through on-site purification. Instead of discarding unused saline solution from disposable bags, the system captures remaining fluid, purifies it through filters and UV treatment, and stores it for future use. This recovery process converts waste into reusable resources, directly addressing the waste generation problem.
2Reliability
If multiple saline bags are used during procedures, then fluid availability is ensured, but labor for opening and switching bags increases
Solution Approach 1:
The portable purification station serves multiple functions: it purifies water, stores purified water in large capacity tanks (up to 40 liters), mixes saline solution, and delivers fluid through regulated flow control. This multi-functional design replaces the need for multiple single-purpose disposable bags, ensuring fluid availability while eliminating repetitive bag handling tasks.
Solution Approach 2:
The system performs preliminary purification and storage of large volumes of water before procedures begin. The portable station can be set up in advance, purified water is stored in ready-to-use tanks, and saline solution is prepared beforehand. This preliminary action eliminates the need for continuous bag switching during procedures, as the system maintains fluid availability from pre-prepared reserves.
3Duration of action of moving object
If saline solution is transported in large volumes, then procedure duration is extended, but delivery frequency and waste increase
Solution Approach 1:
The system provides self-service through on-site water purification. Instead of relying on external delivery of large saline volumes, the system purifies water locally using integrated filters and UV treatment. This eliminates the need for frequent deliveries and allows the system to produce saline solution on-demand, extending procedure duration without increasing waste from undelivered or unused solution.
Solution Approach 2:
The system changes the concentration parameter by mixing purified water with saline concentrate in controlled ratios. This allows precise preparation of the required saline volume and concentration, avoiding waste from delivering excessive amounts of pre-mixed saline. The on-demand mixing capability ensures that only the necessary amount of saline is prepared for each procedure.
