Solution Overview
Problem
Existing hand-held vacuum cleaners have dust containers that can release dust harmful to users' health when opened, and dust collected in the cyclonic separating apparatus can stick to the outer surfaces, making it difficult to remove.
Innovation Solution
A cleaner with a dust separation unit featuring a cyclone for centrifugal separation, a dust container with a dust storage communicating with the flow space, and a cleaning compressor that reciprocates between the flow space and the dust storage, comprising a base member with inclined portions to compress dust without disturbing cyclonic airflow.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the dust container is opened to remove collected dust, then the dust can be removed from the container, but the dust may be released and harm user health and contaminate the surroundings
Solution Approach 1:
The cleaning compressor performs preliminary compression of dust before the dust container is opened. The compressor is activated to compress the dust into a compact mass within the dust container, preventing dust from dispersing when the container is subsequently opened for removal.
Solution Approach 2:
The compression mechanism converts the potentially harmful scattered dust into a beneficial compacted form. By compressing the dust, the system transforms a health hazard (dispersed dust particles) into a manageable, compacted waste material that can be safely removed.
2Strength
If the cleaning compressor has sufficient rigidity to compress dust, then effective dust compression is achieved, but the compressor may disturb the cyclonic airflow
Solution Approach 1:
The base member is divided into multiple segments or portions arranged in a circular pattern. This segmentation allows the compressor structure to achieve the necessary rigidity for dust compression while creating gaps between segments that permit cyclonic airflow to pass through undisturbed, resolving the conflict between structural strength and airflow stability.
Solution Approach 2:
Different portions of the base member have different properties: some portions provide rigid compression surfaces for dust compaction, while other portions are designed with open spaces or reduced density to maintain airflow pathways. This local differentiation allows simultaneous achievement of compression rigidity and airflow stability.
