Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a conventional water pump with impeller and driving motor is used, then pumping function is achieved, but operation noise is large
Solution Approach 1:
The patent replaces the conventional mechanical driving system (motor-impeller) with a magnetic driving system. The magnetic driving part generates a magnetic field that directly acts on the flexible pumping part, eliminating mechanical contact and significantly reducing operation noise while maintaining pumping functionality through magnetic field-driven elastic deformation
Solution Approach 2:
The patent employs a flexible pumping part made of elastic material that can deform under magnetic field action. This flexible membrane structure replaces rigid mechanical components, enabling noise-free operation while effectively pumping water through cyclic deformation that creates pressure differences for water movement
2Object-affected harmful factors
If magnetic field is used to drive flexible pumping part, then operation noise is reduced, but device complexity increases
Solution Approach 1:
The patent integrates the magnetic driving part and flexible pumping part into a unified structure where the magnetic field generator and elastic membrane work together as a single pumping system. This merging eliminates the need for separate mechanical transmission components, reducing overall structural complexity despite introducing magnetic field generation elements
Solution Approach 2:
The patent introduces a magnetic field as an intermediary between the driving mechanism and the pumping action. The magnetic field acts as a non-contact mediator that transfers energy to the flexible pumping part, eliminating mechanical contact and reducing noise while simplifying the overall system architecture by removing mechanical linkages
