Solution Overview
Problem
Existing dust collecting apparatuses face challenges in achieving effective dust separation and storage, with issues such as dust backflow from storage units to separation units and inefficient compression of dust, which affect the overall cleaning performance.
Innovation Solution
The proposed dust collecting apparatus incorporates a dual-stage separation system with cyclone units, a filter unit, and a compression mechanism using a pressing member and fixing member to enhance dust separation and storage, minimizing backflow and optimizing dust accumulation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If a dust storage unit is used to store separated dust, then dust accumulation capacity is improved, but dust may backflow to the dust separation unit
Solution Approach 1:
A pressing member is provided in the dust storage unit to compress the dust before it can backflow. The pressing member applies pressure to the dust in advance, reducing its volume and preventing it from moving back to the dust separation unit, thereby resolving the contradiction between storage capacity and backflow prevention
2Volume of moving object
If a pressing member is used to compress dust, then dust volume is reduced, but air flow between pressing plate and fixing member needs to be managed
Solution Approach 1:
The pressing plate is designed with multiple holes that allow air to pass through during the dust compression process. This porous structure enables air flow management without adding complex mechanisms, as the air can naturally escape through the holes while the pressing member compresses the dust, resolving the contradiction between volume reduction and air flow management complexity
