Segmented Cooling Hydration Bladder for Body Armor
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Body armor causes discomfort and dehydration due to heat retention, and existing hydration solutions are either ineffective, bulky, or prone to mold and bacterial growth, while providing insufficient impact and ballistic protection.
Innovation Solution
Development of multi-utility bladders and containers that provide thermal regulation, hydration, and enhanced impact and ballistic protection by using hollow bodies with partitioned chambers to prevent liquid accumulation, conductive heat absorption, and flexible materials for comfort and security.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If body armor is worn to provide ballistic protection, then life-saving protection is improved, but heat retention increases causing discomfort and dehydration
Solution Approach 1:
The cooling system is divided into multiple independent chambers (first chamber, second chamber, third chamber) that can be separately filled and managed. Each chamber serves a specific function: active cooling, passive cooling, and hydration storage respectively. This segmentation allows the system to provide comprehensive thermal management without compromising ballistic protection.
Solution Approach 2:
Gel packs are introduced as intermediary cooling elements that are placed within the chambers. These gel packs act as thermal mediators between the cooling system and the user's body, providing controlled thermal transfer while maintaining the structural integrity and protective function of the body armor.
2Temperature
If phase change materials are used in cooling vests, then cooling effect is improved, but weight and cost increase while endurance is limited
Solution Approach 1:
The cooling chambers are designed to accommodate multiple types of cooling substances (gel packs, ice, water) and can function in different cooling modes (active and passive). This multi-functionality allows the system to provide effective cooling without being limited to heavy phase change materials, thereby reducing weight while maintaining cooling performance.
Solution Approach 2:
The system allows changing the physical state and type of cooling substance used in different chambers. The first chamber can use gel packs for active cooling, the second chamber can use ice or water for passive cooling, and these can be adjusted based on environmental conditions and user needs, optimizing the weight-effectiveness ratio.
3Quantity of substance
If hydration bladders are used for water delivery, then hydration function is improved, but mold and bacterial growth occur while plastic taste develops
Solution Approach 1:
The hydration system is separated into dedicated chambers (second chamber for ice/water, third chamber for hydration) that are isolated from each other. This segmentation prevents contamination between different substances and makes cleaning and maintenance easier, reducing the risk of mold and bacterial growth while eliminating plastic taste transfer.
Solution Approach 2:
The chambers are designed with transparent or translucent materials that allow visual inspection of the water quality and cooling substances. This enables users to monitor for signs of contamination, algae growth, or deterioration, ensuring hygiene quality and allowing timely replacement of substances before contamination occurs.
4Reliability
If single-use water bottles are used, then water quality and safety are improved, but functionality is limited to water delivery only
Solution Approach 1:
The cooling vest integrates multiple functions into a single system: the first chamber provides active cooling with gel packs, the second chamber provides passive cooling with ice or water, and the third chamber provides hydration. This multi-functional design delivers high-quality water while simultaneously providing thermal regulation, eliminating the need for separate single-use bottles and enhancing overall versatility.
5Temperature
If conventional cooling systems are used, then cooling effect is improved, but mobility and endurance are decreased
Solution Approach 1:
The cooling chambers are designed with flexible, lightweight materials that conform to the body's shape and allow full range of motion. The thin-walled chambers reduce overall weight while maintaining structural integrity, enabling users to maintain mobility and endurance while receiving effective cooling during physical activity.

The solution effectively cools the user, maintains mobility and endurance, reduces dehydration, and provides significant impact and ballistic protection, as demonstrated by reduced backface deformation and improved fluid flow rates.
Implementation Method 1
The body is adapted to receive a substance via the first port and contain the substance for providing thermal regulation to the user's body when the container is in contact with the user's body
Implementation Method 2
providing impact protection when the container is in contact with the user's body

AI summary
Bladders/containers designed to hold a meaningful amount of material (in any state: solid, liquid or gas) to conductively absorb heat from the human body. In addition, the material may be consumed by the user wearing the bladder/container, thus providing a source of hydration for the user. The bladders/containers would also enhance impact and/or ballistic protection of the user.
