Solution Overview

Problem

Existing cleaners require manual handling of components, leading to sanitary issues due to direct contact with dust and potential transfer or dropping of dust during removal processes, especially when using tools like T-shaped tools that can cause incline and dust dispersion.

Innovation Solution

A cleaner design with a detachable cleaning module housing and holder system that allows linear insertion or withdrawal of the cleaning module without direct hand contact, using a hook manipulator for tool-free separation and maintaining the cleaning member's rotational functionality to prevent dust transfer and incline issues.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If manual handling of cleaning components is used, then ease of operation is improved, but sanitary conditions deteriorate due to direct contact with dust

Engineering Contradiction:
Improveease of operationVSAvoidsanitary conditions
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

A holder mechanism serves as an intermediary between the user and the cleaning member. The holder includes a holding portion that engages with the cleaning member and a manipulating portion that the user operates. This intermediary structure allows users to control the cleaning member without direct hand contact, eliminating dust exposure while maintaining operational ease.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Ease of operation

If T-shaped tool is used to open cap, then ease of operation is improved, but device complexity increases due to additional tools required

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

Solution Approach 1:

The function of the T-shaped tool for opening the cap is merged into the holder structure itself. The holder includes a manipulating portion that can be pressed by the user to release the cleaning member, eliminating the need for separate tools while maintaining ease of operation. The cap opening function is integrated into the holder's manipulation mechanism.

Inventive Principle:
Principle #5Merging (Combining)

3Ease of operation

If cleaning member is removed by holding one end, then ease of operation is improved, but dust transfer to housing or floor occurs due to incline

Engineering Contradiction:
Improveease of operationVSAvoiddust transfer
Core Design Contradiction:
Ease of operationVSObject-generated harmful factors

Solution Approach 1:

The holder acts as an intermediary that maintains proper orientation of the cleaning member during removal. The holder includes a holding portion that securely engages the cleaning member and guides its movement, preventing inclination that would cause dust to fall or transfer to the housing. The user manipulates the holder rather than directly holding the cleaning member.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The holder pre-establishes the correct orientation and path for cleaning member removal. By designing the holder with appropriate engagement features and movement guides, the system ensures the cleaning member is removed in a controlled manner that prevents dust dispersion before the user even begins the removal action.

Inventive Principle:
Principle #10Preliminary action

AI summary

A cleaner includes: a cleaner body having therein a module mounting portion; a rotation driving portion provided at one side of the module mounting portion; and a cleaning module detachably mounted to the module mounting portion through one side of the cleaner body, wherein the cleaning module includes: a holder linearly inserted into or withdrawn from the module mounting portion in a side direction of the cleaner body; and a cleaning member supported by the holder so as to be inserted or withdrawn into or from the module mounting portion, together with the holder when the holder is inserted thereinto or withdrawn therefrom, and the cleaning member rotated by a driving force provided from the rotation driving portion.
