Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional processing devices are used to purify water, then purification function is achieved, but device complexity increases
Solution Approach 1:
The patent combines the collection pump, filtration device, and discharge mechanisms into an integrated purification device. The pump unit, filtration unit, and control unit are merged into a single device that processes water from collection to discharge, eliminating the need for separate complex systems while maintaining reliable purification function.
Solution Approach 2:
The purification device performs multiple functions within a single system: water collection through the pump, filtration through the filtration device with filter elements, and controlled discharge. This multi-functional integration reduces overall system complexity while ensuring reliable purification through multiple integrated stages.
2Reliability
If conventional processing devices are used to purify water, then purification function is achieved, but device size increases
Solution Approach 1:
The filtration device is positioned within or adjacent to the pump housing, with the filter elements nested within the filtration chamber. The discharge pump is integrated into the same housing structure, creating a compact nested arrangement that reduces overall device volume while maintaining all necessary purification functions.
Solution Approach 2:
The device utilizes vertical space efficiently by positioning the inflow port at the top, the filtration device in the middle section, and the discharge port at the bottom. This vertical arrangement optimizes the use of three-dimensional space, reducing the device's footprint while ensuring proper water flow and purification function.
3Device complexity
If inflow port is positioned above collection pump, then self-weight driven filtration is enabled, but gravitational flow control becomes challenging
Solution Approach 1:
The control unit monitors water flow through the filtration device and adjusts the discharge pump operation accordingly. This feedback mechanism ensures that gravitational flow from the upper inflow port is properly regulated, preventing overflow or insufficient filtration while maintaining simple pump configuration.
Solution Approach 2:
The system utilizes gravity to drive water flow from the inflow port through the filtration device, eliminating the need for additional pumping power for this stage. The collection pump only needs to provide initial pressure, while the discharge pump handles the final discharge, allowing the system to self-regulate flow through gravitational force.
