Portable Blowing Device with Modular Support Frames for Travel Drying
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Travelers face inconvenience due to slow drying of clothes in damp hotel bathrooms or guest rooms, as existing solutions are not portable or efficient for on-the-go drying.
Innovation Solution
A portable blowing device with a support rod, rotating ring, and blades that can be easily assembled and disassembled, featuring interchangeable support frames for hanging clothes, shoes, or towels, and powered by a rechargeable or disposable battery unit to generate airflow for faster drying.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If clothes are hung in hotel bathrooms or guest rooms to dry, then clothes can be dried without additional equipment, but the drying process is slow due to damp and non-convective environments
Solution Approach 1:
The patent replaces passive air drying (relying on natural convection) with an active mechanical blowing system. The motor-driven blades generate forced airflow that actively removes moisture from clothes, substituting the ineffective natural drying process with a mechanically-powered air circulation system that works independently of ambient conditions.
Solution Approach 2:
The blowing device is designed to be portable and self-contained with an integrated battery pack, allowing it to operate independently without requiring external power sources or infrastructure. The device serves itself by carrying its own power supply and control systems, enabling travelers to dry clothes anywhere without relying on hotel bathroom ventilation or electrical outlets.
2Adaptability or versatility
If a portable blowing device is designed with multiple components for versatility, then the device can handle various drying needs (clothes, shoes, towels), but the device becomes more complex and harder to carry
Solution Approach 1:
The blowing device incorporates multiple support frames with different configurations (hanger-type for clothes, flat-type for shoes and socks, grid-type for towels) that can all be used with the same motor-blade assembly. This universal design allows a single core component to serve multiple drying functions by simply changing the support frame attachment.
Solution Approach 2:
The device is divided into separable modules: the motor-blade assembly, the battery pack, and various support frames. Each module can be independently attached or detached, allowing users to carry only the essential components and add specific support frames only when needed for particular items, thereby reducing overall complexity while maintaining versatility.
3Adaptability or versatility
If the blowing device uses a fixed support structure, then the structure is simple and stable, but the device cannot adapt to different items to be dried (clothes, shoes, socks, towels)
Solution Approach 1:
The support frames are designed with dynamic attachment mechanisms that allow them to be easily connected and disconnected from the lower rod portion. The support frames can be positioned and adjusted to accommodate different item sizes and shapes, transforming a static structure into a dynamic, reconfigurable system that adapts to various drying needs.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables quick and convenient drying of clothes, shoes, and towels in various settings, improving travel convenience by providing a portable and efficient means to manage moisture.
Implementation Method 1
the blades will rotate with the rotating ring to generate the airflow to blow clothes, shoes, socks or towels placed on the support frame

AI summary
A portable blowing device includes at least one support rod and a plurality of blades. The support rod comprises an upper rod portion, a lower rod portion, and a rotating ring that is located between the upper rod portion and the lower rod portion. A hook is disposed on the top end of the upper rod portion, and pluralities of first fixed portions are disposed on the outer surface of the rotating ring. Each blade has a first connection portion for connecting to the corresponding first fixed portion of the rotating ring. When the blowing device is activated, the rotation of blades generates the airflow to blow user or the clothes hung on a support frame.
