Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cleaners face issues with dust accumulation on the upper portion of the compression member, leading to interference with the cyclone flow and deformation of the compression member, which affects performance and durability.
Innovation Solution
A cleaning unit with a guide fence and connection bracket design that blocks air flow to prevent dust accumulation, along with a discharge inclining surface to naturally slide dust away, and a reinforced connection to maintain proper operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a compression member is mounted to compress dust in the dust collection part, then dust collection performance is improved, but dust accumulates on the upper portion of the compression member causing it to fail to restore to initial position
Solution Approach 1:
The patent applies preliminary action by designing an inclining surface on the upper portion of the compression member before dust accumulation occurs. This inclining surface proactively guides dust particles to slide down during the raising movement, preventing dust buildup that would otherwise block restoration to the initial position. The structure is prepared in advance to handle the dust problem rather than reacting to it after occurrence.
2Productivity
If air flow is introduced during cleaner operation, then cleaning function is improved, but air flows to gap between compression member and dust container causing dust accumulation on connection part
Solution Approach 1:
The patent introduces a guide fence as an intermediary element between the air introduction path and the connection part of the compression member. The guide fence intercepts and redirects the air flow, preventing it from directly reaching the connection part where dust would accumulate. This intermediary structure modifies the air flow path to eliminate the harmful effect while preserving the cleaning function.
3Productivity
If compression member raises and lowers during operation, then dust compression is improved, but dust falls to upper side and accumulates on connection part between compression member and handle
Solution Approach 1:
The inclining surface is designed in advance on the upper portion of the compression member to address the dust accumulation problem that occurs during raising and lowering operations. Before dust can accumulate and interfere with the connection part, the inclining surface guides it downward during the raising stroke, preventing the harmful effect from occurring.
4Reliability
If dust accumulates on upper portion of compression member, then compression member is interfered with by dust thickness, but cyclone flow is interrupted and performance deteriorates
Solution Approach 1:
The guide fence acts as an intermediary structure that intercepts air flow before it can transport dust to the connection part. By modifying the air flow path through this intermediary element, the system prevents dust accumulation that would otherwise interfere with the compression member and interrupt the cyclone flow, thereby protecting performance without adding complex active control mechanisms.
