Blower Closed-Loop Power Control for Consistent Air Output
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing outdoor power tools like blowers experience a decrease in air output when different nozzle attachments are used, leading to inconsistent performance.
Innovation Solution
A blower system equipped with a closed-loop power control module that maintains a constant motor power output regardless of the nozzle attachment used, ensuring consistent air output.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If different nozzle attachments are used, then the blower can achieve desired effects with various attachments, but the air output decreases and performance becomes inconsistent
Solution Approach 1:
The controller continuously monitors the actual power output of the motor and compares it to the desired power level. When a nozzle attachment is changed and air output decreases, the feedback mechanism detects the power change and automatically adjusts the motor power to maintain consistent air output. This closed-loop control ensures that regardless of which nozzle attachment is used, the blower maintains its optimal air delivery performance.
Solution Approach 2:
The system dynamically changes the motor power parameter based on the detected air output conditions. When a nozzle attachment modifies the air flow characteristics, the controller adjusts the motor power parameter to compensate for the change, thereby maintaining consistent overall air output. This parameter adjustment occurs automatically without user intervention.
2Adaptability or versatility
If nozzle attachments are coupled to the blower, then the blower can achieve desired effects, but the performance becomes inconsistent across different attachments
Solution Approach 1:
The feedback control system continuously monitors motor power output and automatically adjusts it to maintain consistent air delivery regardless of the nozzle attachment. This ensures reliable and consistent performance across all attachments by detecting and compensating for any variations in air output caused by different nozzle designs.
Solution Approach 2:
The blower system performs self-adjustment through its built-in controller that automatically compensates for the effects of different nozzle attachments. The system monitors its own performance metrics and makes real-time adjustments without requiring user intervention, thereby maintaining consistent performance across all attachments.

AI summary
A blower is provided. The blower includes a blower housing, a motor for driving a fan disposed within the blower housing, and a controller disposed in the blower housing and electrically coupled to the motor for controlling a power output of the motor. The controller is configured to perform a plurality of operations. The plurality of operations include receiving a power setpoint, receiving a measured power, comparing the power setpoint and the measured power to obtain a power difference, generating a control signal based on the power difference, and adjusting the power output of the motor based on the control signal.
