Solution Overview

Problem

Existing cleaners face difficulties in cleaning the filter holes due to clogging, and the dust collector's small space makes it challenging to separate and clean the dust container from the main body.

Innovation Solution

A cleaner design with a separable dust container that can be opened using a single operating member, featuring a handle unit with a movable operating member and a holding mechanism, allowing for easy access and cleaning of the filter by separating the dust container from the main body.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the dust container is integrated with the main body, then the structure is compact, but the filter cannot be easily cleaned

Engineering Contradiction:
Improvefilter cleaning accessibilityVSAvoiddust container separation mechanism
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The dust container is divided into separable parts: the container body and the cover. The cover can be opened independently by operating member 1000 to expose the filter for cleaning, while the entire dust container can be separated from the main body when needed. This segmentation allows filter accessibility without requiring full disassembly.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The cover is extracted as a separate operable component from the dust container body. By removing the cover through the action of operating member 1000, the filter becomes accessible for cleaning while the dust container remains attached to the main body, providing selective access without full separation.

Inventive Principle:
Principle #2Taking out (Extraction)

2Ease of operation

If multiple operating members are used for opening and separating, then each function is precise, but the operation becomes complex

Engineering Contradiction:
Improveopening and separating operationVSAvoidnumber of operating members
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

Operating member 1000 is designed with multi-functionality to perform both opening the dust container cover and separating the dust container from the main body. The operating member can be moved to different positions: a first position to open the cover, and a second position to separate the container, consolidating multiple functions into a single component.

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

Solution Approach 2:

The functions of opening the cover and separating the dust container are merged into a single operating member 1000. This consolidation reduces the number of separate controls the user must learn and operate, simplifying the overall operation while maintaining precise control over each function through different positions of the same member.

Inventive Principle:
Principle #5Merging (Combining)

3Ease of operation

If the dust container cover is always closed, then dust is contained, but the filter cannot be accessed for cleaning

Engineering Contradiction:
Improvefilter accessibilityVSAvoiddust containment
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The dust container cover is designed to be dynamically openable through operating member 1000. The cover transitions between closed and open states based on the position of the operating member, allowing the filter to be accessed for cleaning when needed while maintaining dust containment during normal operation. This dynamic design provides both accessibility and containment.

Inventive Principle:
Principle #15Dynamics

Applied Scientific Principles

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

Function Achieved in This Case

Enables convenient and easy cleaning of the filter by exposing it externally when the dust container is separated, simplifying the process of opening and closing the dust container with a single operating member.

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.
