Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If signal-based detection methods are used to detect electrode misplacement, then detection capability is improved under normal conditions, but detection reliability deteriorates when signals are noisy or when chest leads are used with small physical distances
Solution Approach 1:
The detection function is segmented into two independent parts: visual indication (LEDs on electrodes) and signal analysis. The LEDs provide immediate visual feedback about electrode placement status without relying on signal quality, separating the detection indication from the physiological signal processing.
Solution Approach 2:
LED indicators serve as an intermediary between electrode placement status and user perception. Instead of relying directly on complex signal analysis, the system uses visual LEDs as a mediator to convey placement correctness, which is especially valuable when ECG signals are noisy or ambiguous.
2Measurement precision
If complex algorithms are used for automated electrode misplacement detection, then detection accuracy is improved, but device complexity increases
Solution Approach 1:
The electrode placement verification is made self-service through visual LED indicators that automatically show placement status. The system self-indicates whether electrodes are correctly placed through the running light pattern, eliminating the need for complex automated algorithms to interpret and communicate placement status to the user.
Solution Approach 2:
The system uses LED light states (on/off patterns) as visual indicators to communicate electrode placement status. Different LED patterns indicate different placement conditions, providing intuitive visual feedback without requiring complex computational analysis.
3Ease of operation
If visual indicators (LEDs) are added to electrodes for placement verification, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The LED indicator is merged with the electrode structure itself, combining the functional element (electrode) with the indicator element (LED) into a single integrated component. This reduces overall system complexity by eliminating separate indicator devices and simplifying the interface between electrodes and the control unit.
Solution Approach 2:
The LED-equipped electrodes serve multiple functions: electrical signal acquisition and visual placement indication. The running light mode provides additional functionality for verification without requiring separate verification devices, making the electrode system multi-functional and reducing overall system complexity.
