Solution Overview
Problem
Existing vacuum cleaners face challenges in maintaining high dust separating efficiency while extending filter lifetime, as conventional filters tend to clog, reducing airflow and requiring frequent replacement.
Innovation Solution
A regenerative filter system with multiple layers of filter material, where at least one layer is spaced for regeneration, allowing for continuous filtering and dust removal without the need for replacement, using a filter regenerator to shake off deposited dust during normal use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional filter is used to trap dust particles, then dust separating efficiency is improved, but filter lifetime is reduced due to clogging
Solution Approach 1:
The filter system automatically discards accumulated dust by shaking the filter layers during operation. A shaking mechanism periodically vibrates the filter layers to dislodge and remove trapped dust particles, allowing the filter to recover its cleaning capacity without manual intervention or replacement.
Solution Approach 2:
The filter operates continuously without interruption for maintenance. The shaking mechanism works periodically during normal operation to clear dust buildup, ensuring the filter maintains its separating efficiency throughout its service life without requiring shutdowns or replacements.
2Reliability
If filter layers are held together tightly for filtering, then filtering efficiency is improved, but dust removal during regeneration becomes difficult
Solution Approach 1:
The filter layers transition between two states: during filtering, layers are held together tightly to maximize dust capture; during regeneration, the shaking mechanism loosens and separates the layers to facilitate dust removal. This dynamic state change allows both efficient filtering and effective cleaning.
Solution Approach 2:
The filter operates in periodic cycles alternating between tight configuration for filtering and loose configuration for dust removal. A shaking mechanism periodically activates to separate the layers and dislodge accumulated dust, then the layers return to their tight filtering position.
3Duration of action of stationary object
If filter is regenerated by shaking, then filter lifetime is extended, but airflow resistance may increase if not properly designed
Solution Approach 1:
The filter system performs self-maintenance through automatic shaking during operation. The shaking mechanism is driven by the vacuum cleaner's own motor, using excess energy to vibrate and clean the filter layers without requiring external intervention or additional power sources.
