Wearable Protection Device with Compression Sheaths for Breathability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wearable protective devices lack adequate breathability due to the inability to control the position of the inflatable casing body within the mesh structure, leading to obstructed breathable zones when deflated.
Innovation Solution
A protective device featuring a mesh structure with tie elements and compression sheaths that compress the inflatable casing body in its deflated state, allowing for reduced volume and enhanced breathability by folding the casing body into smaller, non-obstructive configurations within the mesh structure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the inflatable casing body is incorporated into the mesh structure without compression sheaths, then the protective device provides adequate protection, but the breathability of the garment is reduced due to obstructed breathable zones when the casing body is deflated
Solution Approach 1:
The compression sheaths are nested within the mesh structure, and the inflatable casing body portions are nested within the compression sheaths. This nested arrangement allows the casing body to be contained within the compression sheaths when deflated, minimizing obstruction of the breathable zones formed by the mesh structure, while still providing protection when inflated
Solution Approach 2:
The compression sheaths are made of flexible material that can deform to accommodate the inflatable casing body portions when they are inflated, while maintaining compression on the deflated portions. This flexible shell approach allows the sheaths to adapt to both inflated and deflated states without compromising breathability or protection
2Device complexity
If the casing body portions are allowed to expand freely when deflated, then the protective device maintains simplicity, but the overall dimensions and space occupation increase, reducing breathability
Solution Approach 1:
The compression sheaths are nested within the mesh structure, and the inflatable casing body portions are nested within the compression sheaths. This nested arrangement allows the casing body to be contained within the compression sheaths when deflated, minimizing obstruction of the breathable zones formed by the mesh structure, while still providing protection when inflated
Solution Approach 2:
The compression sheaths are made of flexible material that can deform to accommodate the inflatable casing body portions when they are inflated, while maintaining compression on the deflated portions. This flexible shell approach allows the sheaths to adapt to both inflated and deflated states without compromising breathability or protection
3Object-generated harmful factors
If compression sheaths with high elastic properties are used to compress the casing body portions, then the breathability is improved, but the device complexity increases
Solution Approach 1:
The compression sheaths are integrated as part of the inflatable assembly structure, combining the functions of compression, containment, and structural support into a single integrated component rather than adding separate compression mechanisms
Solution Approach 2:
The compression sheaths are nested within the mesh structure, and the inflatable casing body portions are nested within the compression sheaths. This nested arrangement allows the casing body to be contained within the compression sheaths when deflated, minimizing obstruction of the breathable zones formed by the mesh structure, while still providing protection when inflated
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 solution ensures maximum ventilation of the garment by minimizing the space occupied by the deflated casing body, maintaining the inflatable configuration while allowing for effective protection and breathability, with the compression sheaths expanding to accommodate inflation without altering the shape of the casing body.
Implementation Method 1
each compression sheath is designed to cover adheringly a corresponding portion of the casing body in order to compress the casing body portion when it is in said deflated condition, so as to reduce its overall dimensions
Implementation Method 2
each compression sheath is designed to yield and be deformed in said inflated condition of the corresponding casing body portion. Preferably, the compression sheath has elastic properties which are much greater than the elastic properties of the respective casing body

AI summary
A protective device (10, 110) for personal protection of a user is described. The protective device (10) comprises a mesh structure (11, 111) comprising a first mesh portion (18, 118) and a second mesh portion (19, 119) and a plurality of tie elements (5). The first mesh portion (18, 118) and the second mesh portion (19, 119) are situated opposite each other and are connected together by the plurality of tie elements (5). The first mesh portion (18, 118), the second mesh portion (19, 119) and the tie elements (5) define a plurality of inner housings (21, 121) of the mesh structure (11, 111). The protective device (10, 110) includes an inflatable casing body (40, 42, 43) having a plurality of casing body portions (40a, 42a, 43a) wherein each casing body portion (40a, 42a, 43a) is arranged inside a corresponding housing of said plurality of inner housings (21, 221). Each portion (40a, 42a, 43a) of said casing body (40, 42, 43) is configured to assume a deflated condition and an inflated condition inside the corresponding inner housing (21, 121) of the mesh structure (11, 111) and wherein said protective device (10, 110) comprises a plurality of compression sheaths (45, 45a, 46, 46a, 47, 47a). Each compression sheath is designed to cover adheringly a corresponding portion (40a, 42a, 43a) of said casing body (40, 42, 43) so as to compress said portion (40a, 42a, 43a) of the casing body (40, 42, 43) in said deflated condition, and wherein each compression sheath is designed to yield and be deformed in said inflated condition of the corresponding casing body portion (40a, 42a, 43a).
