Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of moving object
If manual ultrasonic probe operation is used, then imaging capability is achieved, but long-term observation of lesions becomes difficult due to operator fatigue and complexity
Solution Approach 1:
The system enables self-service operation through automated ultrasonic scanning. The attachable patch type ultrasonic transducer automatically scans the lesion without requiring continuous manual operation, allowing long-term observation to proceed autonomously while reducing operator burden and maintaining imaging capability.
Solution Approach 2:
The patent replaces the manual mechanical scanning system with an automated electronic scanning system. The ultrasonic transducer array automatically performs scanning movements and signal processing, substituting the mechanical hand-held probe operation with an automated system that can maintain observation for extended periods without fatigue.
2Measurement precision
If CT/MRI imaging techniques are used to scan multiple body parts, then comprehensive vascular disease diagnosis is achieved, but cost increases and radiation exposure occurs
Solution Approach 1:
The patent substitutes ionizing radiation-based imaging (CT/MRI) with non-ionizing ultrasonic imaging. The attachable patch type ultrasonic transducer uses acoustic waves instead of electromagnetic radiation, eliminating radiation exposure while providing real-time vascular imaging capability for comprehensive disease diagnosis.
Solution Approach 2:
The system changes the physical parameter used for imaging from electromagnetic radiation (CT/MRI) to acoustic waves (ultrasonic). This parameter change allows comprehensive vascular imaging of multiple body parts without radiation exposure, maintaining diagnostic accuracy while removing harmful effects.
3Adaptability or versatility
If multiple separate machines are used to check different body parts, then comprehensive vascular disease detection is achieved, but device complexity and test coordination become complicated
Solution Approach 1:
The patent merges multiple separate ultrasonic imaging functions into a single integrated system. The attachable patch type ultrasonic transducer can simultaneously or sequentially scan multiple body parts (carotid artery, heart, peripheral arteries) using one device, eliminating the need for multiple separate machines and simplifying test coordination.
Solution Approach 2:
The ultrasonic transducer is designed with universal applicability to scan various body parts. The same attachable patch type transducer can be applied to different locations (neck for carotid, chest for heart, limbs for peripheral arteries) to perform comprehensive vascular imaging, providing multi-functionality without requiring specialized equipment for each body part.
