Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional electrocardiography devices are used, then accurate heart monitoring is achieved, but the devices are bulky and inconvenient for patients
Solution Approach 1:
The device is segmented into a main body containing essential components (electrodes, battery, processor) and a mobile phone that handles display and communication functions. This segmentation allows the medical monitoring function to be portable while leveraging the mobile phone's capabilities for user interface and data transmission.
Solution Approach 2:
The mobile phone serves multiple functions: it displays ECG results, communicates with clinicians, stores patient data, and provides user interface controls. This multi-functionality eliminates the need for a separate bulky display and communication system, making the device portable and convenient for patients.
2Adaptability or versatility
If traditional electrocardiography devices are used, then heart monitoring is performed, but patients face difficulty accessing regular monitoring outside clinics
Solution Approach 1:
The mobile phone acts as an intermediary between the simple ECG sensing device and the clinical diagnostic system. It receives raw ECG data, transmits it to clinicians remotely, and enables communication without requiring physical presence in a clinic, thus bridging the gap between home monitoring and professional diagnosis.
Solution Approach 2:
The system transitions from location-bound clinic monitoring to location-independent remote monitoring by adding the communication dimension. The mobile phone enables data transmission and clinician communication across spatial distances, allowing patients to be monitored anywhere with mobile network coverage.
3Weight of moving object
If portable design is implemented, then patient convenience is improved, but device functionality must be simplified
Solution Approach 1:
Non-essential functions (display, communication, data storage, user interface) are extracted from the medical monitoring device and placed in the mobile phone. This extraction allows the device to be lightweight and portable while maintaining full monitoring accuracy, as the core ECG sensing and processing functions remain intact in the portable unit.
