Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If additional electrodes are added to increase the number of data streams, then the number of biosignal data streams is improved, but the device cost, space requirements, and complexity increase
Solution Approach 1:
The patent implements dynamic reconfiguration of electrode designations through a switch matrix that can change which electrodes serve as measurement electrodes, reference electrodes, or ground electrodes. This allows a fixed set of electrodes to dynamically create multiple different data streams by altering their functional assignments rather than adding physical electrodes.
Solution Approach 2:
Each electrode in the system is designed to serve multiple functions depending on its designation. The same physical electrode can be assigned as a measurement electrode for one data stream, a reference electrode for another, or a ground electrode, allowing a single electrode to participate in multiple different biosignal measurements through software-controlled reconfiguration.
2Productivity
If additional electrodes are added to increase the number of data streams, then the number of biosignal data streams is improved, but the space requirements increase
Solution Approach 1:
The patent merges the functions of multiple dedicated electrode sets into a single shared electrode array. Instead of having separate electrode pairs for each data stream (which would require more physical space), the system combines all electrodes into one pool that can be dynamically assigned to different measurement functions, reducing the total space required while maintaining the capability to generate multiple data streams.
3Productivity
If additional electrodes are added to increase the number of data streams, then the number of biosignal data streams is improved, but the device cost increases
Solution Approach 1:
The patent changes the operational parameters (designations) of existing electrodes rather than changing the physical hardware. By modifying which electrodes are assigned to which functions through software control of the switch matrix, the system can generate multiple data streams from a fixed, cost-effective electrode set, avoiding the need to manufacture and assemble additional expensive electrode components.
4Device complexity
If electrode designations are fixed, then the device simplicity is improved, but the adaptability to different measurement needs deteriorates
Solution Approach 1:
The patent introduces dynamic reconfiguration capability through a switch matrix that can change electrode designations in real-time. This allows the same simple physical device to adapt to different measurement needs by dynamically assigning electrodes to different functions (measurement, reference, ground) based on the specific biosignal measurement being performed, maintaining simplicity while gaining versatility.
