Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Vacuum cleaners face inefficiencies in maintaining filter cleanliness, leading to reduced performance and frequent filter replacements due to accumulated debris, as existing designs lack effective mechanisms for debris removal from filters.
Innovation Solution
A vacuum cleaner with a filter cleaning device featuring a retractable member and biasing member that applies a momentary impact to the filter, dislodging debris, and a seal system to manage airflow, ensuring effective debris removal and extending filter life.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a filter is used to collect debris from suction airflow, then filtering effectiveness is improved, but debris accumulation on the filter reduces performance and requires frequent replacement
Solution Approach 1:
The filter cleaning device enables the filter to clean itself through the retractable member that delivers mechanical impacts to dislodge accumulated debris, eliminating the need for manual cleaning or replacement and maintaining filtering effectiveness over extended periods
Solution Approach 2:
The biasing member provides periodic mechanical impacts to the filter surface through the retractable member, creating regular cleaning cycles that prevent debris accumulation and maintain filtering performance without continuous intervention
2Quantity of substance
If debris accumulates on the filter, then filtering capacity increases, but vacuum performance decreases and filter replacement frequency increases
Solution Approach 1:
The system automatically discards accumulated debris from the filter surface through mechanical impact by the retractable member, allowing the filter to maintain its debris-capturing capability while preventing performance-degrading accumulation
Solution Approach 2:
The filter autonomously removes its own accumulated debris through the self-cleaning mechanism, maintaining optimal performance without external intervention and extending service life between replacements
3Ease of operation
If a filter cleaning mechanism is added, then filter maintenance is improved, but device complexity increases
Solution Approach 1:
The filter cleaning function is integrated into the existing vacuum cleaner structure, allowing the device to maintain itself automatically without requiring separate manual maintenance operations or complex external systems
Solution Approach 2:
The retractable member provides dynamic cleaning action by moving between retracted and extended positions to deliver controlled mechanical impacts, enabling effective debris removal through simple periodic motion rather than complex continuous mechanisms

AI summary
A vacuum cleaner including a housing, a suction inlet, a suction source, a collector and a filtering unit. The housing includes a suction airflow through the housing. The suction source draws the suction airflow through the suction inlet. The collector receives debris separated from the suction airflow and is disposed between the suction inlet and the suction source. The filtering unit includes a filter, a retractable member, and a biasing member, where the retractable member is operable in directions towards and away from the filter for supplying momentary impact to the filter for providing agitations to rid the filter from debris. The biasing member urges the retractable member towards the filter.
