Solution Overview

Problem

Conventional clothes treatment apparatuses face issues with condensed water leakage and protruding depth of door liners, which affect the efficiency and design of the device.

Innovation Solution

A clothes treatment apparatus with a cabinet design that includes a treatment chamber, a cycle chamber, a partition plate with a drainage grill, a door liner to guide condensed water, and a condensed water guide member with an inclined surface to direct water to the drainage grill, minimizing leakage and protruding depth.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a door liner is installed to guide condensed water, then condensed water leakage is prevented, but the protruding depth of the door liner increases

Engineering Contradiction:
Improvecondensed water leakage preventionVSAvoidprotruding depth of door liner
Core Design Contradiction:
ReliabilityVSLength of moving object

Solution Approach 1:

The patent changes the guiding path of condensed water from a horizontal direction (along the door liner) to a vertical direction (dropping onto the partition plate). The door liner guides water to the upper side of the partition plate, where it drops vertically onto the condensed water guide member, eliminating the need for deep horizontal protrusion.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

Solution Approach 2:

The patent introduces a condensed water guide member as an intermediary component between the door liner and the drainage system. This guide member receives dropped condensed water and directs it to the drainage grill, allowing the door liner to have minimal protrusion while still effectively guiding water away from the cabinet.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If the door liner protrudes deeply to guide condensed water, then water guidance is effective, but the device complexity increases

Engineering Contradiction:
Improvecondensed water guidance effectivenessVSAvoiddoor liner structure complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent divides the condensed water guidance function into two separate components: the door liner (which guides water to the partition plate) and the condensed water guide member (which receives dropped water and directs it to drainage). This segmentation allows each component to have a simple, focused structure rather than requiring a complex integrated solution.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Instead of having the door liner extend deeply into the cabinet to guide water directly to drainage, the patent inverts the approach by having the door liner guide water to the upper side of the partition plate where it can drop vertically. This inverted guidance path simplifies the door liner structure while maintaining effectiveness.

Inventive Principle:
Principle #13The other way round (Inversion)

3Reliability

If condensed water is discharged through the partition plate, then leakage is prevented, but manufacturing precision requirements increase

Engineering Contradiction:
Improvecondensed water leakage preventionVSAvoiddrainage grill positioning precision
Core Design Contradiction:
ReliabilityVSManufacturing precision

Solution Approach 1:

The condensed water guide member is designed with an inclined guide surface that automatically directs water toward the drainage grill using gravity. This self-service design eliminates the need for precise positioning mechanisms or complex alignment systems, reducing manufacturing precision requirements while ensuring reliable water discharge.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent changes the physical parameter of the guide surface from horizontal to inclined, creating a slope that naturally directs water flow toward the drainage grill. This parameter change simplifies the positioning requirements, as the inclined surface compensates for minor misalignments through its gravitational flow direction.

Inventive Principle:
Principle #35Parameter changes

AI summary

A clothes treatment apparatus includes: a cabinet (10) comprising a treatment chamber (12) for allowing clothes to be hung therein and a cycle chamber (14) for allowing machinery to be installed therein, the cycle chamber (14) being located at a lower side of the treatment chamber (12); a partition plate (11) for partitioning the treatment chamber (12) and the cycle chamber (14) from each other; a door (20) for opening and closing the cabinet (10); a door liner (180) disposed at an inside of the door (20) for guiding condensed water generated in the treatment chamber (12) and dropping the condensed water to an upper side of the partition plate (11); and a condensed water guide member (190) disposed at the partition plate (11) for guiding the condensed water dropped from the door liner (180) into the treatment chamber (12). In the clothes treatment apparatus, condensed water that falls along the door liner drops onto the partition plate, thereby minimizing the protruding depth of the door liner. In addition, the dropped condensed water is guided to the drainage grill along the condensed water guide member, thereby preventing the leakage of the condensed water to the outside.
