Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple electrodes are used for electrocardiogram and skin impedance monitoring, then monitoring accuracy is improved, but device complexity increases
Solution Approach 1:
The patent applies multi-functionality by enabling a single electrode to serve dual purposes: electrocardiogram monitoring and skin impedance monitoring. The electrode is configured to collect both types of signals through different coupling methods (AC coupling for ECG, DC coupling for skin impedance), eliminating the need for separate electrode sets and reducing system complexity while maintaining monitoring accuracy.
Solution Approach 2:
The patent merges the electrocardiogram monitoring function and skin impedance monitoring function into a single integrated system using the same physical electrodes. By combining signal collection, processing, and control functions into one unified device, the patent reduces the number of components and simplifies the overall system architecture.

AI summary
An electrode multiplexing physiological parameter monitoring ring, comprising a built-in power supply (2), a microprocessor module (1), an electrocardiogram monitoring analog front end (3), a skin conductance monitoring module (4), a first electrode (6), and a second electrode (7).

The first electrode (6) and the second electrode (7) are further connected to the skin conductance monitoring module (4), and the skin conductance monitoring module (4) processes skin impedance signals collected by the first electrode (6) and the second electrode (7). A coupling manner in which the first electrode (6) and the second electrode (7) are coupled to the electrocardiogram monitoring analog front end (3) is direct current coupling or alternating current coupling, and is opposite to a coupling manner in which the first electrode (6) and the second electrode (7) are coupled to the skin conductance monitoring module (4).
