Multi-Fan Speed Single-Wire Output System Logic Extraction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional multi-fan speed output systems face increased operation load and heat production due to the need for the system end to process rotation speeds of all fans, leading to delays and inefficiencies.
Innovation Solution
A multi-fan speed single-wire output system where the rotation speeds of multiple fans are transmitted to one fan for logical operation to generate an output rotation speed, allowing for easier monitoring and control through electrical connections and logical operations between control elements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the system end processes rotation speeds of all fans, then complete fan speed monitoring is achieved, but system operation load increases and heat production increases
Solution Approach 1:
The patent extracts the logical operation function from the system end and relocates it to one of the fans (specifically, the second fan). The second fan's control element performs the logical operation on received rotation speeds locally, generating the output rotation speed without requiring system end processing. This extraction reduces the system operation load while maintaining complete fan speed monitoring capability.
2Measurement precision
If the system end processes rotation speeds of all fans, then complete fan speed monitoring is achieved, but system heat production increases
Solution Approach 1:
The patent extracts the heat-generating logical operation process from the system end and relocates it to the second fan's control element. By performing the logical operation locally at the fan level rather than at the system end, the heat production is distributed and reduced at the system level, while complete fan speed monitoring is maintained through the output rotation speed generated by the second fan.
3Measurement precision
If the system end processes rotation speeds of all fans, then accurate fan speed data is obtained, but system operation delay occurs
Solution Approach 1:
The patent extracts the time-consuming logical operation from the system end processing queue and performs it locally at the second fan's control element. This parallel execution at the fan level eliminates the sequential processing delay at the system end, enabling accurate fan speed data to be generated without system operation delay, as the second fan independently performs the logical operation on received rotation speeds.
Data Source
AI summary
A multi-fan speed single-wire output system and a method thereof are disclosed. The system includes at least one first fan and one second fan, which have a first and a second rotation speed, respectively. The first fan transmits the first rotation speed to the second fan, and the second fan performs a logical operation on the first and the second rotation speed to generate an output rotation speed.
