Cleaner Dust Compression Frame Guide for Accurate Standby Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cleaners face issues with the dust compression mechanism not accurately moving to its standby position, leading to reduced dust separation performance and potential dust accumulation, causing flow resistance and uneven movement.
Innovation Solution
A cleaner design that incorporates a compression mechanism with relative rotation of transfer parts, allowing the frame to accurately move to a compression standby position by using a guide system with first and second guide parts, ensuring smooth operation and reduced eccentricity, thus guiding air and dust effectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the dust compression part moves in contact with the inner circumferential surface of the dust bin, then the inner circumferential surface is cleaned, but dust may accumulate between the dust compression part and the inner circumferential surface causing uneven movement
Solution Approach 1:
The guide structure is extracted from the dust bin and implemented as a separate, independently installable component. This allows the guide to be pre-assembled and tested separately, then installed into the dust bin, enabling replacement or adjustment without replacing the entire dust bin assembly.
Solution Approach 2:
The guide acts as an intermediary component between the dust compression part and the dust bin. It provides a controlled interface that ensures accurate movement of the dust compression part while preventing dust accumulation issues, mediating the interaction between these two components.
2Productivity
If the dust compression part does not accurately move to the standby position, then it acts as flow resistance degrading dust separation performance, but adding guide structures increases device complexity
Solution Approach 1:
The guide structure is segmented into multiple components including the guide body, guide plate, and guide sleeve. This segmentation allows each component to perform a specific function (constraining movement in different directions) while keeping individual components simple and easy to manufacture.
Solution Approach 2:
Instead of making the dust compression part complex with built-in positioning features, the invention inverts the approach by providing the guide structure in the stationary dust bin to guide the moving part. This simplifies the moving dust compression part while achieving the same positioning accuracy.
3Ease of operation
If the frame is moved by an operating part disposed eccentrically, then the compression mechanism can be actuated, but the frame may not accurately return to the compression standby position
Solution Approach 1:
The guide structure serves as an intermediary that mediates between the eccentric operating mechanism and the frame's standby position. It provides physical constraints that ensure the frame returns to the correct position regardless of the eccentricity of the operating mechanism.
Solution Approach 2:
The guide structure is pre-installed in the dust bin to establish the correct standby position of the frame before operation. This preliminary positioning ensures that even when the eccentric operating part actuates the mechanism, the frame will return to the predetermined accurate standby position.
