Solution Overview

Problem

Conventional dryers lack additional functions beyond drying, requiring users to perform separate processes for wrinkle removal, odor elimination, and energy efficiency, which complicates user interaction and increases energy consumption.

Innovation Solution

A dryer with a control panel and controller that allows users to select from various courses, including steam processes for moisture control, enabling crease removal, static electricity reduction, and odor elimination, while optimizing drying conditions based on detected dryness and laundry amount.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a conventional dryer is used for simple drying, then energy consumption is reduced, but additional functions for wrinkle removal and odor elimination cannot be performed

Engineering Contradiction:
Improveadditional functionsVSAvoidenergy consumption
Core Design Contradiction:
Adaptability or versatilityVSUse of energy by moving object

Solution Approach 1:

The dryer integrates multiple functions including drying, wrinkle removal, odor elimination, and refresh functions into a single device. The control panel provides various course selections (e.g., drying course, wrinkle removal course, odor removal course, refresh course) that can be independently chosen based on user needs, allowing the dryer to perform different operations without requiring separate appliances.

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

2Ease of operation

If multiple additional functions are added to the dryer, then convenience is improved, but device complexity increases

Engineering Contradiction:
Improveuser convenienceVSAvoidcontrol complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The control panel is segmented into distinct course selection buttons for different functions (drying, wrinkle removal, odor removal, refresh). Each course is independently selectable and clearly labeled, allowing users to choose only the needed function without being overwhelmed by a complex unified interface. The controller processes each course selection separately with dedicated control logic.

Inventive Principle:
Principle #1Segmentation

3Adaptability or versatility

If steam process is used for wrinkle removal and odor elimination, then functionality is improved, but energy consumption increases

Engineering Contradiction:
Improvesteam functionsVSAvoidenergy loss
Core Design Contradiction:
Adaptability or versatilityVSLoss of energy

Solution Approach 1:

The steam generation is performed periodically rather than continuously. The controller activates the steam generator only during specific time intervals when steam is needed for wrinkle removal or odor elimination, then stops generation. This periodic operation reduces overall energy consumption compared to continuous steam generation while maintaining the effectiveness of steam-based functions.

Inventive Principle:
Principle #19Periodic action
