Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional ECG measuring instruments are used, then measurement accuracy can be ensured, but the device size becomes large and portability is poor
Solution Approach 1:
The conventional ECG instrument is segmented into a wearable body portion and separate fittings (electrode clips). The body contains the electrocardiosignal collection circuit and electrodes, while the fittings provide additional electrode attachment points. This segmentation allows the main device to remain compact and wearable while distributing measurement functions across multiple components.
Solution Approach 2:
The electrocardiosignal collection circuit and electrodes are integrated within the wearable body structure. The fittings with additional electrodes can be attached to the body or used independently, creating a nested configuration where the measurement system is contained within the wearable device form factor.
2Reliability
If conventional ECG measuring instruments are used, then comprehensive electrocardiosignal detection can be achieved, but the device is not easy to carry and cannot achieve in-time measurement
Solution Approach 1:
The wearable device provides multiple measurement modes through different electrode configurations. The body alone can perform basic ECG measurement, while the fittings add additional measurement capabilities. This multi-functionality ensures reliable electrocardiosignal detection while maintaining portability and ease of use in various scenarios.
Solution Approach 2:
The fittings are designed to be detachable and movable relative to the body, allowing the device to adapt to different measurement needs and body positions. This dynamic configuration enables the user to carry only the essential body portion for portability while adding fittings when comprehensive detection is required.
3Measurement precision
If multiple electrodes are used for comprehensive measurement, then measurement coverage is improved, but device structure becomes more complex
Solution Approach 1:
The multiple electrodes are segmented into two groups: electrodes integrated in the wearable body and electrodes in the detachable fittings. This segmentation allows comprehensive measurement coverage while keeping the main body structure simple and the additional electrodes easily attachable or removable based on measurement needs.
