Garment with Bladder Holes for Targeted Gas Cooling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing temperature control garments for hazardous environments are often uncomfortable to wear, especially under chemical protection suits, and may have complicated gas supply arrangements.
Innovation Solution
A temperature control garment with a bladder for receiving a gas supply, featuring adjustable shoulder straps and targeted temperature control regions with concentrated holes for gas distribution, which can be worn under protective garments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a uniform arrangement of holes is provided over the entire surface of the inner layer, then gas is distributed evenly across the torso, but the garment becomes less comfortable and more cumbersome to wear
Solution Approach 1:
The patent applies local quality by concentrating holes in specific targeted temperature control regions rather than distributing them uniformly across the entire garment surface. This creates non-uniform gas distribution that focuses cooling where the body generates the most heat, improving comfort while reducing overall garment complexity.
2Ease of operation
If separate cooling jacket and breathing apparatus are used, then temperature control and gas supply functions are provided, but the arrangement of flexible fluid conduits becomes complicated and untidy
Solution Approach 1:
The patent merges the cooling jacket and breathing apparatus into a single integrated garment structure. The bladder serves dual purposes as both a cooling chamber and a breathing gas reservoir, while the same hole arrangement serves both cooling and breathing functions. This eliminates the need for separate flexible conduits and reduces overall system complexity.
Solution Approach 2:
The garment components are designed with multi-functionality: the bladder serves as both cooling chamber and breathing gas reservoir, the holes serve both cooling and breathing purposes, and the garment structure simultaneously provides temperature control and gas supply functions, reducing the need for separate dedicated components.
3Productivity
If holes are concentrated in targeted temperature control regions, then gas is directed to areas needing cooling most, but the temperature distribution becomes non-uniform
Solution Approach 1:
The patent deliberately creates non-uniform temperature control by concentrating holes in targeted regions where the body generates the most heat. This localised approach improves cooling efficiency in critical areas without requiring uniform temperature distribution across the entire garment surface.
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
The garment effectively regulates body temperature while being more comfortable and less cumbersome than existing solutions, with a simplified gas supply system that reduces clutter and enhances user safety.
Implementation Method 1
an arrangement of holes provided in the bladder for directing gas supplied to the chamber towards the user's body
Implementation Method 2
directing gas supplied to the chamber towards the user's body so as to modify the temperature of the user's body

AI summary
There is disclosed a temperature control garment 16 arranged to be worn on a user's torso, comprising a bladder 74 defining a chamber for receiving a supply of gas, the bladder comprising at least a back portion 76 which is arranged to overlie at least a portion of a user's back. An arrangement of holes 92 is provided in the bladder for directing gas supplied to the chamber towards the user's body so as to modify the temperature of the user's body. The garment 16 also comprises a breathing duct 54 coupled to the bladder for receiving a supply of gas, the breathing duct having at least one duct outlet 66, 68 for delivering the gas supplied to the breathing duct 54 to the user.
