Innovation Solution
A self-regulated system that integrates diagnostics and prognostics to estimate the State of Health and Remaining Useful Life of electrochemical devices, adjusting operating parameters in real-time to prevent degradation and extend device life, using sensors and a computer circuit unit to monitor and control parameters like voltage and pressure, and implement countermeasures for reversible disruptions.

Engineering Contradiction Analysis
1Reliability
If simple regulatory control is used to maintain the system at specified conditions, then the control implementation is simple, but the device lifetime and performance cannot be maximized due to inability to detect and respond to abnormal conditions
Solution Approach 1:
The patent implements a feedback mechanism where measurements from sensors are continuously fed into a computer circuit unit that estimates diagnostics data and prognostics data. This feedback loop enables the system to detect abnormal conditions, estimate their impact on lifetime, and adjust operating parameters accordingly, thereby maximizing device lifetime while maintaining manageable complexity through automated intelligent control.
Solution Approach 2:
The system performs self-diagnosis and self-optimization by automatically monitoring its own state through integrated sensors, estimating its health status and remaining useful life, and adjusting its operating parameters without external intervention. This self-service capability enables the system to maximize its own lifetime and performance while keeping the control architecture relatively simple.
2Ease of operation
If remote control with off-line information is used, then the control is simple to implement, but it does nothing beyond running the device within specified parameters and cannot prevent faulty conditions
Solution Approach 1:
The patent replaces simple mechanical/regulatory control with an intelligent electronic control system that uses sensors, a computer circuit unit, and algorithms to automatically detect faulty conditions, estimate their impact on lifetime, and adjust operating parameters. This substitution maintains ease of operation through automated electronic control while dramatically improving fault detection and prevention capabilities.
Solution Approach 2:
The computer circuit unit acts as an intermediary between the sensors and the operating organs, processing measurements to estimate diagnostics and prognostics data, then generating appropriate control commands. This intermediary enables sophisticated fault detection and lifetime optimization while keeping the overall system architecture simple and easy to implement.
3Duration of action of stationary object
If integrated diagnostics and prognostics system is implemented to maximize lifetime, then the device lifetime and performance are maximized, but the system complexity increases
Solution Approach 1:
The patent merges sensors, a computer circuit unit, diagnostics algorithms, and prognostics algorithms into an integrated control system. This merging enables simultaneous estimation of current health status and remaining useful life, allowing the system to maximize its lifetime and performance while managing complexity through integration rather than separate independent systems.
Solution Approach 2:
The computer circuit unit performs multiple functions: it receives measurements from various sensors, estimates diagnostics data to assess current health status, estimates prognostics data to predict remaining useful life, and generates control commands to adjust operating parameters. This multi-functionality enables comprehensive lifetime optimization while avoiding the complexity of multiple separate dedicated systems.
