Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If time measurement is used to determine remaining capacity, then capacity can be calculated, but the method becomes impractical in extreme environments and requires complex time tracking
Solution Approach 1:
The patent extracts the time measurement dependency from the capacity determination process by using a time-independent method. Instead of measuring current over time intervals, the system directly integrates current through an integrator circuit to determine capacity, eliminating the need for time measurement and making the system suitable for extreme environments where time tracking is unreliable.
Solution Approach 2:
The patent replaces the mechanical/time-based measurement system with an electrical integration system. By using an integrator circuit to accumulate charge directly, the system substitutes complex time measurement and calculation mechanisms with a straightforward electrical integration process, improving both accuracy and ease of operation.
2Reliability
If complex monitoring systems are deployed for remote monitoring, then monitoring capability is improved, but system complexity and cost increase
Solution Approach 1:
The patent creates a universal monitoring system that can be applied to various power supply types (batteries, fuel cells, capacitors) using the same basic integration principle. The system provides multiple functions including local display, remote monitoring via communication interfaces, and integration with existing power management circuits, reducing overall system complexity while maintaining reliability.
Solution Approach 2:
The patent introduces communication interfaces as intermediaries that bridge the simple integration circuit with remote monitoring systems. These intermediaries handle the complexity of remote communication protocols and data transmission, allowing the core capacity measurement system to remain simple while enabling sophisticated remote monitoring capabilities.

Data Source
AI summary
The remaining capacity of a battery may be monitored with a microprocessor by integrating a voltage measured across a current sense resistor coupled in series with the battery. The microprocessor may measure electrons passing through the battery by sampling the integrator and summing the values recorded from the integrator. Each time the integrator is sampled, the microprocessor may reset the integrator to prevent the integrator from saturating. The remaining capacity of the battery may be calculated based on calibration values and the sum of electrons measured by the integrator. The remaining capacity may be communicating to remote users through a network and displayed in an executive dashboard.
