Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a stationary filter is used in a fish pond, then the structure is simple and easy to maintain, but garbage impurities accumulate on the filter surface over time, reducing filtration efficiency and requiring frequent manual cleaning
Solution Approach 1:
The filter cylinder is designed to rotate automatically through water flow pressure differences. The cylindrical structure with inclined filtration surfaces rotates around a central axis, allowing garbage to be continuously swept from one location to another and discharged periodically, eliminating the need for manual cleaning and maintaining consistent filtration efficiency
Solution Approach 2:
The system automatically discards accumulated garbage through periodic discharge mechanisms. The rotating filter cylinder brings accumulated garbage to discharge ports where it is removed from the system, allowing the filter to recover its filtration capacity continuously without manual intervention
2Productivity
If the filter cylinder rotates continuously to prevent garbage accumulation, then filtration efficiency is improved, but the mechanical wear and energy consumption increase
Solution Approach 1:
The filter cylinder rotates automatically utilizing the natural water flow pressure difference created during filtration. The pressure differential between the inner and outer surfaces of the rotating cylinder provides the driving force, eliminating the need for external motors or power sources while maintaining continuous rotation and high filtration efficiency
3Duration of action of stationary object
If a backwashing device is added to clean the filter cylinder, then the service life is prolonged, but the device complexity increases
Solution Approach 1:
The backwashing function is merged with the existing rotation and discharge mechanism. The same rotating structure that prevents garbage accumulation also facilitates backwashing by directing water flow through the filter media in reverse during specific rotation phases, cleaning the filter surface without requiring separate backwashing equipment
Solution Approach 2:
The backwashing process utilizes hydraulic principles by directing water flow through the filter cylinder in reverse during rotation. Water is injected through nozzles positioned to strike the filter surface, using fluid pressure and flow dynamics to dislodge and remove accumulated particles, extending filter life through automated hydraulic cleaning
