Solution Overview
Problem
Existing cleaners face issues with dust compression parts obstructing airflow and creating gaps that allow dust to accumulate, leading to reduced dust compression performance and uneven movement.
Innovation Solution
A cleaner design featuring a movable frame that surrounds the cyclone flow axis, guiding airflow and preventing dust from entering gaps between movable parts, with an inclined frame structure to ensure smooth air flow and minimize deformation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the dust compression part is located higher than the opening at standby position, then the dust compression part can be accommodated in the dust bin, but the internal space of the dust bin is reduced and air flow is not guided
Solution Approach 1:
The dust compression part is designed with an inclined surface that extends upward beyond the opening plane, utilizing the vertical dimension to guide airflow while maintaining adequate internal space. The inclined surface creates a gradual transition that directs air flow without completely blocking the opening, resolving the contradiction between space utilization and flow guidance.
2Length of moving object
If the dust compression part is located higher than the opening, then the vertical length for dust compression is reduced, but dust compression performance deteriorates
Solution Approach 1:
The dust compression part features a curved inclined surface that gradually transitions from the opening upward. This curved geometry allows the compression part to extend beyond the opening while maintaining sufficient vertical compression distance through the angled approach, improving dust compression performance without sacrificing compression length.
3Ease of operation
If the dust compression part moves in contact with the inner circumferential surface, then the inner surface can be cleaned, but dust may be caught between them causing uneven movement
Solution Approach 1:
The dust compression part is designed with a flexible or elastically deformable material that allows it to conform to the inner circumferential surface during cleaning. This flexibility prevents rigid contact that would trap dust, enabling smooth movement while maintaining effective cleaning contact between the compression part and surface.
