Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for cleaning sweat, such as handkerchiefs and towels, become wet and smelly when used frequently, especially during intense physical activity, failing to effectively manage profuse sweating.
Innovation Solution
A sweat wicking and absorbing device with layers of hydrophobic and hydrophilic materials, including a middle absorbent layer, a palm or finger insertion unit, and optional features like pockets and a sweat biomarker monitoring sensor, designed to efficiently absorb and manage sweat without getting wet or smelly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If handkerchiefs, tissues or towels are used to clean sweat, then sweat can be cleaned occasionally, but the device gets wet and stinks when used frequently
Solution Approach 1:
The device is divided into multiple functional layers: an outer hydrophobic layer that repels sweat, an inner hydrophilic layer that attracts and absorbs sweat, and a middle absorbent layer that captures and retains sweat. This segmentation allows each layer to perform its specific function, preventing the entire device from becoming wet and smelly while maintaining effective sweat cleaning.
Solution Approach 2:
The device uses composite materials with different surface properties - hydrophobic material for the outer layer to repel sweat, hydrophilic material for the inner layer to attract sweat, and absorbent material for the middle layer to capture sweat. This composite structure enables the device to effectively manage sweat without becoming wet or odorous, resolving the contradiction between cleaning effectiveness and odor/wetness resistance.
2Productivity
If traditional sweat cleaning methods are used, then simple and inexpensive, but ineffective during profuse sweating
Solution Approach 1:
The middle absorbent layer is designed with porous structure that allows it to rapidly absorb and retain large quantities of sweat. The porosity enables high capillary action and absorption capacity, allowing the device to manage profuse sweating effectively while maintaining reliability during intense physical activity.
Solution Approach 2:
The middle absorbent layer acts as an intermediary between the hydrophilic inner layer and the external environment. It captures sweat from the inner layer and retains it through absorption, preventing sweat from reaching the outer layer and causing odor. This intermediary function significantly increases sweat management capacity while maintaining cleaning effectiveness.

AI summary
A fluid wicking and absorbing device is disclosed. The device may include a first layer made of a flexible hydrophobic material, and a second layer made of a flexible hydrophilic material. The device may further include a third layer disposed between the first layer and the second layer. The third layer may be made of a flexible fluid absorbent material. The device may additionally include a palm or finger insertion unit disposed on the first layer. The palm or finger insertion unit may include four edges. A first pair of opposing edges may be attached to the first layer, and a second pair of opposing edges may not be attached to the first layer and forms an opening configured to receive a user palm or finger.
