Headgear Cooling Structure With Top Water Inlet and Drain Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional evaporative cooling structures for headgear require soaking or pouring water, which is inconvenient and can cause splashing, and often necessitate a separate container, making them impractical for outdoor activities.
Innovation Solution
A headgear design with a water inlet at the top for pouring water directly onto a sheet-like absorbent material covered by moisture-permeable and waterproof fabric, featuring a water channel and drain outlet to manage water flow and excess, allowing easy and controlled water supply without a separate container.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If water is poured onto sheet-like cooling structure from above, then water can be supplied to the cooling structure, but water splashes around which is unpleasant
Solution Approach 1:
The patent introduces a container with a nozzle as an intermediary device between the water source and the cooling structure. The nozzle controls water discharge in a directed manner, preventing splashing while ensuring water reaches the cooling structure effectively. This mediator resolves the contradiction by enabling water supply without the harmful splashing effect.
Solution Approach 2:
The patent utilizes hydraulic principles through the nozzle design to control water flow. By shaping the nozzle opening and positioning it appropriately, the water stream is focused and directed precisely onto the cooling structure, eliminating scattered splashing while maintaining effective water delivery for cooling purposes.
2Quantity of substance
If a container is used to hold water for soaking the water-absorbent material, then sufficient water can be stored, but it is inconvenient to prepare the container and water in outdoor settings
Solution Approach 1:
The patent merges the water container, nozzle, and cooling structure into a single integrated headgear unit. The container is positioned within the headgear body, and the nozzle is built into the structure, eliminating the need for separate containers and preparation steps. This combination maintains adequate water storage while dramatically improving portability and ease of use in outdoor settings.
Solution Approach 2:
The headgear structure serves multiple functions: it acts as a container holder, provides structural support for the nozzle, houses the cooling material, and functions as the wearable item itself. This multi-functionality eliminates the need for separate water containers and preparation equipment, making the system universally applicable and convenient for outdoor activities.
3Temperature
If the main body portion is soaked in water, then evaporative cooling can be achieved, but there is the inconvenience of wringing out excess water and disposing of remaining water
Solution Approach 1:
The patent designs the system to automatically manage water distribution and excess removal without requiring user intervention for wringing or disposal. The nozzle provides controlled water delivery, and the cooling structure's design allows excess water to drain naturally or be absorbed, enabling the system to self-regulate water management while maintaining effective evaporative cooling.
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
Provides quick and long-lasting evaporative cooling without splashing, enabling easy water replenishment from a plastic bottle, suitable for outdoor activities, and effective in preventing heat stroke.
Implementation Method 1
a relatively thick sheet-like water-absorbent material capable of absorbing and storing an amount of water equivalent to multiple times the weight of the water-absorbent material
Implementation Method 2
cooling a head, a back of a neck and surrounding areas through evaporative cooling effect of water
Implementation Method 3
a moisture-permeable and waterproof fabric having holes as evaporation ventilation windows on some areas

AI summary
A water inlet is provided at a top portion of a main body portion of a headgear or the like for pouring water from a plastic bottle into the water inlet. The back side of the main body portion and a flap portion are covered with moisture-permeable waterproof fabrics on one side or partially on both sides of sheet-like absorbent materials. A gap is formed as a water channel for water to flow between the absorbent materials and the moisture-permeable waterproof fabrics. A drain outlet is provided at the bottom edge of the flap portion to detect the fact that the water reaches the bottom edge. The absorbent materials are placed avoiding a head circumference size adjustment portion and a boundary connection portion between the main body portion and the flap portion. A water channel is connected in a sheath-tube manner formed of moisture-permeable waterproof fabric.
