Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If wired connections are used in ECG monitoring systems, then measurement reliability is improved, but patient mobility is restricted
Solution Approach 1:
The patent replaces the mechanical wired connection system with a wireless electromagnetic communication system. Each active electrode contains a wireless transmitter that communicates cardiac signals to a hub device without physical cable connections, thereby maintaining measurement reliability while enabling patient mobility.
Solution Approach 2:
The patent introduces a hub device as an intermediary that receives wireless transmissions from multiple active electrodes and processes the cardiac signals. This intermediary coordinates the wireless communication between electrodes and the monitoring system, ensuring reliable data collection without wired connections.
2Adaptability or versatility
If multiple electrode configurations are provided for different patient sizes, then adaptability is improved, but device complexity increases
Solution Approach 1:
The patent employs a universal active electrode design that can be used across all patient sizes and configurations. The same type of active electrode with wireless transmission capability serves multiple functions in different electrode arrangements (3-lead, 5-lead, 12-lead), eliminating the need for multiple specialized electrode types.
Solution Approach 2:
The patent enables dynamic reconfiguration of electrode placements and connections through software control rather than requiring physical reconfiguration of multiple electrode types. The hub device can dynamically assign different electrode configurations based on patient needs while using the same universal electrode hardware.
3Measurement precision
If a common reference point is provided for wireless measurements, then measurement precision is improved, but device complexity increases
Solution Approach 1:
The patent merges the reference electrode function into the hub device rather than requiring a separate physical reference electrode. The hub device consolidates the common reference point for all wireless measurements, providing measurement precision while reducing the number of separate components needed.

AI summary
An ECG monitoring system includes two or more active electrodes, each active electrode having an electrode pad fixable to a patient to sense physiological potentials from the patient, a common connection port, and a wireless transmitter. The system further includes a common connector electrically connected to the common connector port of each of the two or more active electrodes to provide a comparator signal to each of the active electrodes. Each of the active electrodes compares the physiological potentials sensed at the electrode pad against the comparator signal to generate a cardiac signal, and then wirelessly transmits the cardiac signal with the wireless transmitter.
