Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If the vehicle-mounted electrical device operates constantly at high power consumption levels, then the signal amplification function is maintained, but the battery charge depletes rapidly leading to power supply insufficiency
Solution Approach 1:
The patent implements dynamic power consumption adjustment by detecting battery charge levels and automatically adapting the power consumption of the signal amplifier. When charge is sufficient, the device operates at high power for optimal signal amplification. When charge becomes insufficient, the device automatically reduces power consumption or shuts down to prevent battery depletion, thus resolving the contradiction between maintaining high power operation and ensuring power supply sufficiency.
2Device complexity
If the vehicle-mounted electrical device lacks charge detection capability, then the device structure remains simple, but the battery may be depleted causing safety hazards and poor user experience
Solution Approach 1:
The patent enables the electrical device to perform self-detection of battery charge levels through integrated detection circuits. The device automatically monitors its own power source status, determines charge sufficiency, and makes autonomous decisions about power consumption adjustment without requiring complex external monitoring systems. This self-service approach provides reliable battery protection while maintaining relatively simple device structure.
3Device complexity
If the vehicle-mounted electrical device does not provide power warnings, then the device functionality remains basic, but users cannot be aware of potential battery power risks
Solution Approach 1:
The patent implements a feedback mechanism where the detection circuit continuously monitors battery charge levels and provides real-time information feedback to the user through warning indicators. When charge falls below threshold levels, the system automatically generates power warnings to alert users of potential battery depletion risks. This feedback loop ensures users are informed of power status without significantly increasing device complexity.

AI summary
A method and system for controlling a vehicle-mounted electrical device, a computer-readable storage medium, and a computer device are provided. The method includes: acquiring, by a detection and control circuit, a real-time voltage of a power source and determining, by the detection and control circuit, a type of the power source through comparing the real-time voltage with a criterion voltage, wherein the detection and control circuit acquires the real-time voltage in a wired manner or in a wireless manner; invoking a charge control range corresponding to the type of the power source, and determining whether an alarm is required and whether to control a power supply to an electrical apparatus based on a relationship between the charge control range and a real-time remaining charge of the power source.
