Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a conventional filter structure is used, then assembly is simple, but capacity adjustment is limited and power terminals may disconnect under water pressure
Solution Approach 1:
The filter case is divided into multiple compartments using partition plates, with each compartment accommodating separate CDI plates. This segmentation allows independent adjustment of capacity by adding or removing CDI plates while maintaining structural integrity and terminal connections under water pressure.
Solution Approach 2:
The filter case employs a dynamic design where CDI plates can be added or removed to adjust capacity based on requirements. The partition plates and support structures are designed to maintain stable terminal connections even when the configuration changes, allowing adaptability without compromising reliability.
2Productivity
If multi-stage deionization is implemented, then purification efficiency increases, but structural complexity increases
Solution Approach 1:
The filter case is segmented into multiple compartments using partition plates, with each compartment housing CDI plates for sequential deionization stages. This segmentation enables multi-stage purification while maintaining a relatively simple overall structure through modular design.
Solution Approach 2:
Multiple CDI plates are combined within a single filter case structure, sharing common supports, terminals, and housing. This merging approach achieves multi-stage deionization functionality while avoiding the need for separate complex structures for each stage, thus improving purification efficiency without proportionally increasing structural complexity.
3Speed
If water pressure is applied for efficient purification, then purification speed increases, but power terminals may disconnect
Solution Approach 1:
The partition plates and support structures are designed to counterbalance the force of water pressure applied during purification. This counteracting structural design prevents terminal disconnection by maintaining stable mechanical connections even under high water pressure, allowing fast purification without compromising reliability.
Solution Approach 2:
The filter case incorporates pre-designed support structures and rigid partition plates that provide mechanical cushioning against water pressure before it can cause terminal disconnection. This beforehand structural reinforcement ensures terminal stability is maintained under the high pressure conditions required for fast purification.
