Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If component faults are diagnosed using traditional methods, then device operation continues, but component faults remain undetected and difficult to locate
Solution Approach 1:
The system performs preliminary fault detection by continuously monitoring electrical characteristics before failures occur. Sensors measure parameters such as resistance, voltage, and current during normal operation, and the processor compares these measurements against stored baseline profiles to identify deviations indicating potential faults in components like antennas, batteries, or connectors before they cause device failure.
Solution Approach 2:
The patent replaces manual or mechanical fault diagnosis methods with an automated electrical measurement system. Instead of physically inspecting or testing components, the system uses sensors to electrically characterize components and the processor to analyze electrical profiles, substituting mechanical diagnostic procedures with automated electrical sensing and computational analysis.
2Difficulty of detecting and measuring
If sensors and processing systems are added to detect component faults, then fault detection capability improves, but device complexity increases
Solution Approach 1:
The system achieves multi-functionality by using a single sensor assembly and processor configuration that can detect faults in multiple different components (antenna, battery, connectors) through a unified electrical characterization approach. The same hardware infrastructure serves various diagnostic purposes, reducing the need for separate specialized sensors for each component type.
Solution Approach 2:
The device performs self-diagnosis by continuously monitoring its own component electrical characteristics. The sensors measure electrical parameters of integrated components, and the processor automatically compares measurements against stored profiles to identify faults, enabling the device to self-monitor and self-diagnose without external diagnostic equipment or manual intervention.

AI summary
A communication device including an electrical component, a sensor, and an electronic processor. The sensor is coupled to the electrical component and is configured to sense an electrical characteristic of the electrical component. The electronic processor is configured to receive, from the sensor, a series of measurements corresponding to the electrical characteristic and determine, from the series of measurements, a first electrical characteristic profile. The electronic processor is further configured to compare the first electrical characteristic profile to a predetermined electrical characteristic profile to generate a comparison and generate an indication of a possible loose connection based on the comparison.
