Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the pump is designed with open components for ease of manufacture and maintenance, then manufacturing cost and repairability are improved, but fluid exposure causes component malfunction and reliability deteriorates
Solution Approach 1:
The patent applies flexible membranes as sealing elements between the pump head and motor housing. These membranes allow magnetic coupling for power transmission while preventing fluid penetration, thus protecting internal components from fluid exposure while maintaining a sealed structure that improves reliability without compromising manufacturing feasibility
Solution Approach 2:
The patent introduces a membrane as an intermediary sealing element that enables power transmission from the motor to the pump head while blocking fluid penetration. This intermediary component allows the pump to maintain both open-component accessibility for maintenance and sealed protection for reliability
2Reliability
If the pump housing is made completely sealed to prevent fluid exposure, then reliability is improved, but access to pumphead connection assembly and display controls becomes difficult
Solution Approach 1:
The patent segments the housing into distinct sections with separate access panels for the pumphead connection assembly and display controls. This segmentation allows each component to be accessed independently through dedicated openings, maintaining overall sealing for reliability while providing ease of operation for maintenance and control functions
3Productivity
If the pump operates continuously without monitoring, then productivity is improved, but leak detection is lost leading to potential damage and waste
Solution Approach 1:
The patent incorporates sensors that continuously monitor the pump operation and fluid levels, providing feedback to the control system. This enables real-time detection of leaks and abnormal conditions, allowing the system to maintain continuous operation for productivity while detecting issues that protect against damage and waste
