Suction Collection Station Noise Control Using Presence Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing suction material collection stations for vacuum cleaning devices often disturb users or animals with background noise during operation, as they lack effective noise control mechanisms to ensure quiet operation when regeneration of the filter chamber is necessary.
Innovation Solution
Incorporating a control and evaluation device that calculates an environmental disturbance parameter based on detected or received presence and device parameters, allowing the operation of the fan to be controlled such that regeneration occurs only when minimal noise pollution is expected, using detection devices like image acquisition devices, ultrasonic sensors, microphones, and radio modules to assess the vicinity for presence of people or animals.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the fan is operated to regenerate the filter chamber, then the suction material is effectively removed from the filter chamber, but background noise disturbs users or animals in the vicinity
Solution Approach 1:
The control and evaluation device performs preliminary detection of presence parameters (using image acquisition devices, ultrasonic sensors, microphones, or radio modules) before initiating fan operation. This allows the system to assess whether the area is occupied and schedule or adjust regeneration operations accordingly, preventing noise disturbance before it occurs.
Solution Approach 2:
The system dynamically adjusts fan operation based on real-time environmental conditions. The control and evaluation device continuously monitors presence parameters and modifies the regeneration process accordingly - either delaying operation until the area is clear, reducing fan speed to minimize noise, or rescheduling the regeneration task to a quieter time period.
2Productivity
If the fan operates at high power to quickly clear the filter chamber, then regeneration speed increases, but noise emission increases and disturbs the environment
Solution Approach 1:
The control and evaluation device implements partial action by adjusting fan speed based on actual needs. Instead of always operating at maximum power, the system uses detection data to determine appropriate fan speeds - using lower speeds when possible to reduce noise, and only increasing power when necessary to achieve effective regeneration within acceptable time frames.
