Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple sterile disposable components are used for pressure measurement, then measurement reliability is improved, but device complexity and handling difficulty increase
Solution Approach 1:
The patent combines multiple separate components (measurement chamber, pressure sensor, connection elements, venting mechanisms) into a single integrated disposable pressure measurement device. This integration maintains measurement reliability while reducing the number of separate components that need to be assembled and handled, thereby reducing device complexity and handling difficulty.
Solution Approach 2:
The disposable device is designed to perform multiple functions within a single unit: pressure measurement, fluid isolation, venting, and connection to measurement systems. This multi-functionality eliminates the need for multiple separate components, reducing both device complexity and the number of sterile articles needed while maintaining reliable pressure measurement.
2Reliability
If multiple sterile disposable components are used for pressure measurement, then measurement reliability is improved, but handling time increases
Solution Approach 1:
By integrating multiple functions into a single disposable unit, the patent reduces the number of assembly steps required during patient examinations. The pre-assembled nature of the device eliminates time-consuming assembly operations while maintaining measurement reliability through proper integration of all necessary components.
Solution Approach 2:
The disposable pressure measurement device is pre-assembled and prepared in advance with all necessary components (measurement chamber, sensor, connections, venting) already in place. This preliminary preparation eliminates the need for time-consuming assembly during patient examinations, reducing handling time while ensuring reliable measurement through proper pre-configuration.
3Measurement precision
If multiple sterile disposable components are used for pressure measurement, then measurement precision is improved, but logistical problems increase
Solution Approach 1:
The patent integrates all necessary components for precise pressure measurement into a single disposable unit, including the measurement chamber, pressure sensor, fluid isolation barriers, and connection elements. This integration maintains measurement precision while simplifying logistics by reducing the number of separate sterile articles that need to be managed, stored, and assembled.
Solution Approach 2:
The single disposable device performs multiple functions: precise pressure measurement, fluid isolation, venting, and connection. This multi-functionality maintains measurement precision while reducing logistical complexity by eliminating the need to manage multiple separate sterile components, their storage, and their assembly during examinations.
4Reliability
If complicated handling procedures are used for pressure measurement, then measurement reliability is improved, but ease of operation deteriorates
Solution Approach 1:
By combining all necessary components and functions into a single integrated disposable device, the patent eliminates complicated assembly and handling procedures. The device is designed to be simple to attach and use while maintaining reliable pressure measurement through proper integration of all necessary components.
Solution Approach 2:
The disposable pressure measurement device is designed as a self-contained unit that requires minimal assembly or preparation by the user. All necessary components are pre-configured and integrated, allowing for simple attachment and immediate use, thereby improving ease of operation while maintaining measurement reliability.
