Solution Overview

Problem

Conventional clothing treatment apparatuses generate wrinkles in clothes due to friction and require additional ironing, and they often occupy too much space in utility rooms due to their fixed installation.

Innovation Solution

A wall-mountable clothing treatment apparatus with a detachable design, featuring a first body and a second body that can extend or rotate, equipped with a hot air supply system including fans, heaters, and strategically positioned air inflow and outflow holes to efficiently dry and refresh clothes, while optimizing space usage.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If clothes are subjected to washing and drying procedures in conventional clothing treatment apparatuses, then clothes are cleaned and dried, but wrinkles are generated due to friction with the drum and clothes cannot maintain normal shape

Engineering Contradiction:
Improveclothes shape maintenanceVSAvoidwrinkles
Core Design Contradiction:
ReliabilityVSObject-generated harmful factors

Solution Approach 1:

Instead of using a rotating drum that creates friction and wrinkles, this invention inverts the approach by using a stationary rack system with clothes hung vertically. The drying process uses hot air circulation rather than mechanical rotation, eliminating the friction-induced wrinkles while maintaining effective drying functionality.

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

Solution Approach 2:

The invention replaces the mechanical drum rotation system with a thermal air circulation system. Hot air is generated by a heater assembly and circulated through the drying chamber using a fan, substituting mechanical agitation with thermal convection for the drying process, thereby preventing wrinkle formation.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

2Area of stationary object

If a wall-mountable design with detachable first and second bodies is used, then space utilization is improved and installation flexibility is enhanced, but device complexity increases

Engineering Contradiction:
Improveinstallation spaceVSAvoidapparatus structure
Core Design Contradiction:
Area of stationary objectVSDevice complexity

Solution Approach 1:

The drying apparatus is divided into a first body (main housing) and a second body (door assembly with rack), allowing the second body to be detachably mounted to the first body. This segmentation enables flexible wall-mounted installation while maintaining a relatively simple overall structure, as each component can be independently manufactured and assembled.

Inventive Principle:
Principle #1Segmentation

3Productivity

If hot air supply system with fan and heater assembly is implemented, then drying efficiency is improved and clothes are refreshed, but energy consumption increases

Engineering Contradiction:
Improvedrying efficiencyVSAvoidenergy consumption
Core Design Contradiction:
ProductivityVSUse of energy by moving object

Solution Approach 1:

The hot air supply system operates continuously during the drying cycle, with the heater assembly and fan working together to maintain constant hot air circulation throughout the drying chamber. This continuous action ensures efficient and uniform drying of clothes, maximizing productivity while minimizing total energy consumption by avoiding intermittent operation.

Inventive Principle:
Principle #20Continuity of useful action
