Fan Control System Boot Verification via Detection Circuit
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
During the manufacturing process of fan control systems, it is challenging to determine if the system operates normally when power is first supplied or when it is booted, as the fan controller initially controls the fan to not turn due to low loading conditions, making it difficult to assess the system's functionality.
Innovation Solution
A fan control system comprising a controller and a detection circuit that generates a confirmation signal based on the system's state, allowing for immediate identification of normal or abnormal operation, including the use of a power detector, temperature sensor, over-current protection circuit, and over-voltage protection circuit to assess the system's components and output an alarm signal if issues are detected.

Engineering Contradiction Analysis
1Loss of energy
If the fan controller controls the fan not to turn under low loading conditions according to control rules, then energy consumption is reduced, but it becomes impossible to verify if the fan control system operates normally during manufacturing or boot-up
Solution Approach 1:
The detection circuit performs preliminary detection of system states (power supply, temperature, loading) before the fan controller makes its normal operational decision to keep the fan stationary. This preliminary action enables verification of system functionality during manufacturing and boot-up without triggering the fan to turn, thus maintaining energy savings while enabling verification.
Solution Approach 2:
A detection circuit is introduced as an intermediary component between the power supply and the fan controller. This detection circuit monitors system states and generates detection signals that enable verification of system operation without requiring the fan to actually turn, thus allowing verification while maintaining the energy-saving control strategy.
2Productivity
If the fan controller keeps the fan stationary during boot-up due to low loading, then the control system operates efficiently, but observers cannot immediately know if the system operates normally
Solution Approach 1:
The detection circuit provides feedback signals about system states (power supply status, temperature, loading conditions) to observers or testing equipment. This feedback mechanism allows observers to immediately know if the system is operating normally without requiring the fan to turn, thus maintaining efficiency while providing necessary status information.
Solution Approach 2:
The detection circuit acts as an intermediary that translates internal system states into observable detection signals. This allows observers to obtain information about system operational status without the fan actually running, preserving system efficiency while eliminating information loss.
3Reliability
If additional detection circuits and confirmation signals are added to verify system operation, then system verification capability is improved, but device complexity increases
Solution Approach 1:
The detection circuit is designed to perform multiple functions: detecting power supply status, temperature, loading conditions, and generating confirmation signals for verification. By making the detection circuit multi-functional, the patent achieves improved verification capability without proportionally increasing complexity, as a single circuit performs multiple detection tasks.
Solution Approach 2:
The patent combines multiple detection functions (power detection, temperature sensing, loading detection) into a single integrated detection circuit that generates a unified confirmation signal. This merging approach improves verification capability while minimizing the increase in device complexity by consolidating multiple functions into one circuit rather than adding separate circuits for each function.
