Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual management of pore device information is used, then device simplicity is maintained, but information accuracy and reliability deteriorate due to human errors
Solution Approach 1:
The patent merges the information storage function directly into the pore device by integrating a nonvolatile memory unit. This combines the measurement device and information management functions into a single integrated system, eliminating the need for separate manual tracking systems and external databases, thereby improving information reliability without proportionally increasing overall system complexity
Solution Approach 2:
The pore device performs self-service by automatically storing and managing its own information including manufacturing details, usage history, and calibration data in the integrated nonvolatile memory. This self-management capability eliminates human intervention for information recording, preventing human errors while maintaining operational simplicity
2Loss of information
If information is stored externally, then device simplicity is maintained, but information accessibility and integration deteriorate
Solution Approach 1:
The patent combines the information storage unit with the pore device itself, ensuring that all critical information is immediately accessible to the measurement system. This integration eliminates information loss risks associated with external storage and ensures seamless data access during measurement operations
Solution Approach 2:
The nonvolatile memory unit is pre-configured with manufacturing information and calibration data before the pore device is put into service. This preliminary preparation ensures that all necessary information is already available and properly formatted for immediate use, eliminating delays and accessibility issues that would arise from external information retrieval

Function Achieved in This Case
This solution ensures accurate and reliable information management, enhancing the precision of particle size distribution measurements and facilitating better design refinement and quality control by eliminating human input errors and enabling non-contact data retrieval.
Implementation Method 1
a measurement terminal group for applying an electric signal from the measurement device to the two chambers and outputting an electric signal generated in the two chambers to the measurement device
Implementation Method 2
a nonvolatile memory and interface means connected to the nonvolatile memory so that the nonvolatile memory is accessible from an outside of the pore device
Implementation Method 3
an electrolytic solution containing particles is passed through a pore called a nanopore. When the particles pass through the pore, the electrolytic solution in the pore decreases by an amount corresponding to a volume of the particles, and an electrical resistance of the pore is increased
Implementation Method 4
When a potential difference is generated between the electrode 106 and the electrode 108, an ion current flows between the electrodes, and the particles 4 move from one chamber to the other chamber via a pore 104 by electrophoresis
