Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If operator-based probe positioning is used, then measurement can be performed, but measurement precision deteriorates due to uncertainty in probe positioning
Solution Approach 1:
The system provides visual feedback through icons indicating the type of tissue detected beneath the probe. This feedback loop allows the operator to adjust probe positioning until the desired tissue type is confirmed, thereby improving measurement precision without increasing operational complexity
Solution Approach 2:
The system performs preliminary tissue identification and verification before the actual measurement is taken. By detecting and confirming the tissue type in advance through ultrasonic signal analysis, the system ensures that measurements are only performed on the correct tissue, eliminating positioning errors
2Measurement precision
If operator expertise is increased, then measurement precision improves, but device complexity worsens due to requirement for specialized knowledge
Solution Approach 1:
The system performs automatic tissue identification and verification without requiring operator expertise in tissue characterization. The ultrasonic transducer and processing system automatically detect tissue properties and confirm target tissue presence, making the device self-sufficient and eliminating the need for specialized operator knowledge
Solution Approach 2:
The system replaces the operator's manual tissue identification skills with an automated ultrasonic signal analysis system. The processing system automatically analyzes reflected ultrasonic signals to identify tissue type, substituting mechanical/operator-based judgment with automated electronic detection
3Ease of operation
If probe positioning is approximate, then ease of operation improves, but reliability worsens due to potential measurement of wrong tissue
Solution Approach 1:
The system performs preliminary verification of tissue identity before measurement using ultrasonic signal analysis. By detecting characteristic acoustic properties of the target tissue in advance, the system ensures reliable tissue identification while maintaining simple probe placement procedures
Solution Approach 2:
The system provides visual feedback through icons that confirm the type of tissue detected. This feedback mechanism allows the operator to verify correct tissue placement immediately, ensuring reliability while maintaining ease of operation through intuitive visual confirmation
