Solution Overview

Problem

Conventional cleaners require users to operate multiple buttons to separate the dust separator from the main body and the dust container, leading to complexity, potential dust spillage, and inefficient space utilization, as well as a risk of the dust container falling and spilling its contents when separated.

Innovation Solution

A cleaner design featuring a button with protrusions that securely attach and detach the dust separator and container, incorporating an elastic mechanism to prevent accidental detachment and a sliding protrusion system to prevent the container from falling, allowing for various coupling methods and directions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If multiple buttons are installed for separating dust separator and dust container, then separation functions are achieved, but device complexity increases and space utilization decreases

Engineering Contradiction:

Improveseparation functionVSAvoidbutton quantity

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The patent combines two separate buttons (one for dust separator separation and one for dust container separation) into a single integrated button. This button includes a first protrusion that interacts with the dust separator and a second protrusion that interacts with the dust container, allowing both separation functions to be achieved through one component, thereby reducing device complexity while maintaining operational functionality.

Inventive Principle:

Principle #5Merging (Combining)

2Ease of operation

If dust container is separated from dust separator, then dust container can be removed, but dust container may fall due to gravity causing dust spillage

Engineering Contradiction:

Improvedust container removalVSAvoiddust spillage

Core Design Contradiction:

Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The patent applies preliminary anti-action by providing a dust container support protrusion that extends from the dust separator to support the dust container's weight before separation is complete. This support structure prevents the dust container from falling due to gravity during the separation process, thereby eliminating dust spillage while still allowing easy removal when needed.

Inventive Principle:

Principle #9Preliminary anti-action

3Ease of operation

If button allows dust container separation, then dust container can be detached, but dust container may be accidentally separated from dust separator

Engineering Contradiction:

Improvedust container detachmentVSAvoidaccidental separation prevention

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The patent employs a button with a rotationally symmetric structure that can be rotated to different positions. The button includes positioning protrusions that engage with corresponding features on the dust separator and dust container only at specific rotational positions. This curved/rotational design allows the button to accidentally rotate without causing accidental separation, as the protrusions simply disengage and re-engage at different positions rather than triggering unintended detachment.

Inventive Principle:

Principle #14Spheroidality (Curvature)

AI summary

A cleaner capable of separating a dust separator from a main body and separating a dust container from the dust separator by using a button. The cleaner includes: a main body; a dust separator detachably coupled to the main body configured to separate dust contained in air; a dust container detachably coupled to the dust separator; and a button configured to separate the dust separator from the main body and separate the dust container from the dust separator, when the dust separator is separated from the main body.
