Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If hydro automatic units and complex valve mechanisms are used to control liquid flow, then liquid distribution can be achieved, but the device complexity increases and reliability decreases due to structural failures
Solution Approach 1:
The patent removes hydro automatic units and complex valve mechanisms from the system, replacing them with a simplified flow control system that uses pressure differential and gravity to automatically regulate liquid flow between the displacement cavity and storage cavity, thereby reducing device complexity while maintaining operational capability
Solution Approach 2:
The system employs self-regulating flow control where the pressure differential between cavities and gravity automatically manage liquid distribution without external control mechanisms, eliminating the need for complex valves and hydro automatic units
2Device complexity
If pressure in the displacement cavity drops to atmospheric pressure, then liquid flow control is simplified, but intermittent purified liquid supply occurs due to pressure drops
Solution Approach 1:
The system pre-establishes pressure differential by maintaining pressure in the displacement cavity above atmospheric pressure through the pressure increasing means, ensuring continuous driving force for liquid flow before purification is needed, thereby preventing intermittent supply
Solution Approach 2:
The patent ensures continuous liquid flow by maintaining persistent pressure differential through the pressure increasing means and contra-flow arrangement, eliminating pressure drops that would cause intermittent supply, thus ensuring uninterrupted purified liquid delivery
3Productivity
If the polymer container changes shape to displace liquid, then liquid movement is achieved, but structural failures may occur reducing reliability
Solution Approach 1:
The patent replaces the mechanical shape-changing polymer container system with a pressure-based displacement mechanism using the pressure increasing means, which pushes liquid through contra-flow arrangement without relying on container deformation, thereby eliminating structural failure risks while maintaining liquid displacement functionality
4Reliability
If pressure increasing means is added to maintain pressure, then continuous liquid supply is achieved, but device complexity increases
Solution Approach 1:
The pressure increasing means serves multiple functions simultaneously: it maintains pressure in the displacement cavity above atmospheric pressure, provides continuous driving force for liquid flow, and works with the contra-flow arrangement to enable both purification and displacement functions, thereby justifying its addition despite increased complexity
