Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional sensor inserting device is used without pre-insertion checking, then the insertion procedure is simple and quick, but unnecessary invasions occur and patient stress increases when faulty sensors are inserted
Solution Approach 1:
The signal processor is connected to the sensor before insertion, enabling pre-checking of sensor functionality. This preliminary action allows detection of faulty sensors before they are inserted into the patient's body, preventing unnecessary invasions and patient stress while maintaining device reliability.
Solution Approach 2:
The signal processor serves multiple functions: it processes signals from the sensor during pre-checking, validates sensor functionality before insertion, and can continue to process signals after insertion. This multi-functionality enables reliability checking without requiring a separate dedicated checking device, thus managing device complexity.
2Productivity
If a conventional sensor inserting device is used without real-time checking, then the device structure remains simple, but insertion efficiency decreases due to inability to detect issues immediately
Solution Approach 1:
The signal processor is connected and configured to perform pre-checking of sensor functionality before insertion. This preliminary validation enables immediate detection of faulty sensors or insertion issues, preventing wasted time and procedures, thereby improving insertion efficiency without requiring complex post-insertion checking systems.
Solution Approach 2:
The signal processor provides real-time feedback on sensor functionality and insertion status. This feedback mechanism allows operators to immediately identify and correct issues, improving insertion efficiency by preventing progression with faulty sensors while maintaining a relatively simple device structure through integrated signal processing.
3Object-affected harmful factors
If the signal processor is connected before insertion as disclosed, then unnecessary insertions are prevented, but the device structure becomes more complex
Solution Approach 1:
The signal processor is connected to the sensor before insertion to perform functionality validation. This preliminary checking prevents faulty sensors from being inserted, eliminating patient stress associated with unsuccessful insertions and repeated procedures. The integrated design manages structural complexity by combining checking and insertion functions in one system.
Solution Approach 2:
The signal processor performs multiple functions including pre-insertion validation, real-time monitoring, and fault detection. This multi-functionality reduces the need for separate dedicated checking devices, managing device structural complexity while effectively preventing patient stress through comprehensive sensor validation before and during insertion.
4Measurement precision
If conventional insertion procedures are used without pre-checking, then the operating procedure remains simple, but measurement precision decreases due to undetected sensor faults
Solution Approach 1:
The signal processor is connected before insertion to validate sensor functionality and ensure proper operation. This preliminary checking detects potential faults that would compromise measurement precision, ensuring accurate biological information collection. The integrated design maintains ease of operation by automating the checking process within the existing insertion workflow.
Solution Approach 2:
The signal processor provides feedback on sensor functionality and signal quality before and during insertion. This feedback mechanism enables operators to identify and correct issues that would affect measurement precision, while the automated nature of the feedback system maintains ease of operation by not requiring complex manual checking procedures.
