Solution Overview

Problem

Conventional dryer stands are inconvenient for changing the direction of drying air discharge, especially when drying objects with frequently changing positions, and lack air purification functionality, requiring separate air purifiers.

Innovation Solution

A rotatable dryer stand with an integrated air purification unit that adjusts the direction of drying air discharge based on the object's position and size, and manages dryer functions according to battery charge levels.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the dryer is mounted on a conventional stand, then the user can place the dryer without holding it, but the user cannot easily change the direction of drying air discharge when the object position changes

Engineering Contradiction:
Improveease of dryer placementVSAvoidadaptability to changing object positions
Core Design Contradiction:
Ease of operationVSAdaptability or versatility

Solution Approach 1:

The dryer stand incorporates a rotatable mechanism that allows the dryer to be dynamically repositioned in the horizontal direction. The rotation unit enables the dryer to rotate around the vertical axis, changing the discharge direction of drying air to match the position of objects needing drying, thus resolving the contradiction between ease of placement and adaptability to changing positions.

Inventive Principle:
Principle #15Dynamics

2Device complexity

If the dryer is integrally formed with the stand, then the structure is simplified, but the user cannot directly carry or hold the dryer for portable drying operations

Engineering Contradiction:
Improvestructural simplicityVSAvoidportability and manual operation capability
Core Design Contradiction:
Device complexityVSAdaptability or versatility

Solution Approach 1:

The system is divided into separable components: the dryer unit and the stand unit. The dryer can be detached from the stand, allowing users to carry or hold the dryer for portable drying operations. When mounted on the stand, the dryer benefits from the stand's rotation and air purification functions. This segmentation resolves the contradiction between structural simplicity and portability.

Inventive Principle:
Principle #1Segmentation

3Device complexity

If the stand only provides mounting function, then the structure is simple, but the user must provide a separate air purifier for indoor air purification

Engineering Contradiction:
Improvestand structure simplicityVSAvoidair purification functionality
Core Design Contradiction:
Device complexityVSAdaptability or versatility

Solution Approach 1:

The air purifier is integrated into the dryer stand, combining the mounting function with air purification functionality. The air purifier unit is positioned within the stand structure, allowing it to purify indoor air while the dryer operates. This merging resolves the contradiction between structural simplicity and functional versatility by adding air purification without requiring a completely separate system.

Inventive Principle:
Principle #5Merging (Combining)

4Device complexity

If the dryer operates without battery charge monitoring, then the control system is simple, but the dryer cannot optimize battery usage and may fail during operation

Engineering Contradiction:
Improvecontrol system simplicityVSAvoidoperational reliability and battery management
Core Design Contradiction:
Device complexityVSReliability

Solution Approach 1:

The dryer incorporates a battery charge monitoring system that provides feedback on the remaining charge. The controller receives charge level information and adjusts dryer operation accordingly, such as reducing power consumption or alerting the user to charge the battery. This feedback mechanism resolves the contradiction between control system simplicity and operational reliability by adding intelligent battery management.

Inventive Principle:
Principle #23Feedback

AI summary

A method of controlling a dryer stand, which includes a receptacle allowing a dryer for discharging drying air to be mounted and rotatable in a horizontal direction, and an air purification unit, is disclosed. The method includes (a) detecting the dryer mounted on the receptacle, (b) charging a battery provided in the dryer when the dryer mounted on the receptacle is detected, (c) determining whether a predetermined condition for air purification operation is satisfied, and (d) operating the air purification unit when it is determined that the predetermined condition for air purification operation is satisfied, whereby it is possible to purify indoor air.
