Solution Overview

Problem

Existing cleaners face difficulties in easily separating and cleaning the dust container from the main body, particularly due to the small space between the dust collector and cover, which makes it hard to maintain and clean the filter member.

Innovation Solution

A cleaner design featuring a separable dust container with a single operating member that can open and close the dust container, utilizing a handle unit with a movable operating member and a locking mechanism to facilitate easy separation and cleaning of the filter member.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of repair

If the dust container is made separable from the main body, then ease of cleaning the filter member is improved, but device complexity increases due to additional locking and separation mechanisms

Engineering Contradiction:
Improveease of cleaningVSAvoiddevice complexity
Core Design Contradiction:
Ease of repairVSDevice complexity

Solution Approach 1:

The dust container is divided into separable parts (dust container body, cover, and filter member) that can be independently removed and cleaned. The locking mechanism allows the dust container to be separated from the main body without requiring complete disassembly of the cleaner.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The filter member is extracted as a separate removable component from the dust container. This allows the filter member to be easily removed for cleaning without needing to separate the entire dust container from the main body, simplifying the maintenance process.

Inventive Principle:
Principle #2Taking out (Extraction)

2Ease of operation

If a single operating member is used to control both opening and separation, then ease of operation is improved, but device complexity increases due to the multi-functional mechanism

Engineering Contradiction:
Improveease of operationVSAvoiddevice complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The operating member is designed as a universal control element that performs multiple functions: it controls both the opening/closing of the dust container cover and the separation of the dust container from the main body. This consolidates multiple control operations into a single mechanism, improving ease of operation.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The locking mechanism combines the cover locking function and the dust container separation locking function into a single integrated system. The operating member interacts with this combined locking mechanism to achieve both operations, reducing the number of separate controls needed.

Inventive Principle:
Principle #5Merging (Combining)

AI summary

A cleaner includes: a main body that forms an external shape; a dust container that is separably combined with the main body and stores dust separated from air; a dust container cover that is configured to open and close the dust container; a handle unit that is disposed behind the dust container; and an operating member that is configured to provide operation force to the dust container cover by moving in a first direction and to release a holding mechanism for preventing separation of the dust container from the main body by moving in a second direction opposite to the first direction.
