Solution Overview
Problem
Existing filter cleaning systems for air conditioning devices face challenges in efficiently cleaning air filters clogged with catkins and hair, leading to high maintenance costs and potential server overheating due to reduced air intake efficiency.
Innovation Solution
A filter cleaning system that uses a combination of an adsorption assembly, washing assembly, and brush assembly, controlled by a sensing unit and control unit, to selectively clean or replace filters based on pressure differences across the filter, optimizing cleaning parameters such as adsorption force, washing time, and sequence to maintain air intake efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the filter is directly replaced when clogged, then air intake efficiency is restored, but maintenance costs increase
Solution Approach 1:
The system recovers the filter by cleaning it in place using the cleaning mechanism (brushes, water spray, air blow) instead of discarding it. The control unit activates the cleaning mechanism when the sensor detects clogging, allowing the filter to be reused after cleaning, thereby reducing maintenance costs while restoring air intake efficiency.
Solution Approach 2:
The system provides self-service by automatically detecting filter clogging through the sensor and activating the cleaning mechanism without manual intervention. The control unit monitors the filter status and initiates the cleaning process autonomously, reducing the need for manual maintenance while maintaining air intake efficiency.
2Loss of substance
If the filter is cleaned in place, then maintenance costs are reduced, but cleaning effectiveness may be insufficient for heavily clogged filters
Solution Approach 1:
The cleaning mechanism is segmented into multiple components working in sequence: brushes for mechanical scrubbing, water spray for washing, and air blow for drying. This segmented approach ensures thorough cleaning of different types of contaminants, maintaining cleaning effectiveness while enabling in-place cleaning to reduce maintenance costs.
Solution Approach 2:
The control unit changes cleaning parameters (brush rotation speed, water spray pressure, air blow intensity) based on the degree of clogging detected by the sensor. This adaptive parameter adjustment ensures effective cleaning for various levels of contamination while maintaining cost efficiency through in-place cleaning.
3Ease of operation
If manual cleaning is performed, then cleaning flexibility is high, but operation complexity and time consumption increase
Solution Approach 1:
The system performs self-service cleaning by automatically detecting filter clogging and activating the cleaning mechanism without manual intervention. The control unit monitors filter status and initiates cleaning autonomously, eliminating the time consumption and operational complexity of manual cleaning while maintaining flexibility through programmable control.
Solution Approach 2:
The sensor provides feedback to the control unit about filter clogging status, which automatically triggers the cleaning mechanism. This feedback loop enables automatic operation, reducing time consumption and operational complexity while maintaining cleaning flexibility through programmable response thresholds and sequences.
4Reliability
If high-pressure water spray is used for cleaning, then cleaning power is increased, but risk of filter damage increases
Solution Approach 1:
The cleaning mechanism is segmented into multiple stages: gentle brush cleaning first, then moderate water spray, and finally air blow for drying. This segmented approach applies increasing cleaning power progressively, ensuring effective removal of contaminants while protecting filter integrity through gradual rather than immediate high-pressure application.
Solution Approach 2:
The brush cleaning stage serves as a cushioning preliminary action before water spray, gently removing loose contaminants and preparing the filter surface. This beforehand cushioning reduces the impact of subsequent water spray on the filter, preventing damage while maintaining cleaning power for embedded contaminants.
