Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cyclonic dust-separating apparatuses in vacuum cleaners have poor dust separating efficiency due to a single cyclone unit and require cumbersome removal for dust collection, with potential air leakage issues from unstable installation.
Innovation Solution
A multi cyclone dust-separating apparatus with a body unit and cover unit that can move horizontally, allowing easy coupling and decoupling, and featuring a horizontal movement permitting part to prevent collision and ensure a tight seal, even when unstably positioned.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a multi cyclone dust-separating apparatus is used to improve dust separating efficiency, then dust separating efficiency improves, but the entire apparatus must be removed from the cleaner body to empty the dust-collecting unit, making it troublesome to operate
Solution Approach 1:
The dust-separating apparatus is divided into a first cyclone unit and a second cyclone unit that can be independently removed from the cleaner body. The second cyclone unit with its dust-collecting unit can be detached separately, allowing users to empty dust without removing the entire apparatus, thus resolving the contradiction between maintaining high dust separating efficiency and improving ease of operation.
2Device complexity
If the air inflow part has a vertical surface coupled with a vertical surface of the dust separating apparatus connecting part, then the structure is simple, but air leakage occurs when the apparatus is unstably arranged or wrongly positioned
Solution Approach 1:
The air inflow part is designed with a curved surface that corresponds to a curved surface of the dust separating apparatus connecting part. This curved interface provides better sealing performance compared to vertical surfaces, preventing air leakage when the apparatus is unstably arranged or wrongly positioned, while maintaining reasonable structural simplicity.
3Device complexity
If a single cyclone unit is used, then the device complexity is low, but dust separating efficiency is poor
Solution Approach 1:
The dust-separating apparatus incorporates both a first cyclone unit and a second cyclone unit, each capable of separating dust from air. This segmentation into multiple functional units increases dust separating efficiency while keeping each individual unit relatively simple in structure, resolving the contradiction between device complexity and productivity.
