Ventilated Garment Mesh Layer Drainage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing outdoor garments with ventilation systems either compromise on breathability due to multiple layers or fail to prevent moisture from precipitation, leading to user wetness during rain or snow.
Innovation Solution
A ventilated garment design featuring a shell with an auxiliary layer and a mesh layer that traps snow or rain, allowing air ventilation while directing moisture to a drain opening, minimizing user contact with the mesh layer even when it becomes saturated.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If multiple layers are incorporated for ventilation between layers, then breathability is improved, but construction cost and complexity increase
Solution Approach 1:
The patent implements nesting by placing a mesh layer within the ventilation opening structure, where the mesh layer is positioned between the outer shell and inner lining. This nested configuration allows the mesh to perform moisture trapping and drainage functions while being integrated into the existing ventilation pathway, eliminating the need for separate complex multi-layer ventilation systems.
2Ease of manufacture
If ventilation openings are kept open, then breathability is improved, but moisture from precipitation reaches the user
Solution Approach 1:
The mesh layer serves as an intermediary element positioned within the ventilation opening. It mediates between the external environment (where precipitation occurs) and the internal garment space (where the user is protected). The mesh allows air to pass through for ventilation while intercepting and trapping snow and rain, channeling it to drainage pathways to prevent moisture from reaching the user.
Solution Approach 2:
The patent converts the harmful effect of precipitation entering ventilation openings into a beneficial drainage system. The mesh layer captures snow and rain that would otherwise wet the user, and channels this collected moisture through drainage pathways to the outside, transforming the potential harm of open vents during precipitation into a controlled drainage benefit.
3Object-affected harmful factors
If mesh layer is used to trap snow and rain, then moisture protection is improved, but user contact with mesh layer increases
Solution Approach 1:
The mesh layer is nested within the ventilation opening structure, positioned between the outer shell and inner lining. This nested placement ensures that the mesh operates in the external ventilation pathway rather than contacting the user's body directly. The inner lining acts as an additional barrier layer that prevents user contact with the mesh, maintaining comfort while preserving moisture protection.
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 design effectively prevents user wetness by channeling moisture externally through the drain opening while maintaining ventilation, ensuring the user remains dry and comfortable during precipitation.
Implementation Method 1
a mesh layer supported between the ventilated portion of the shell and the auxiliary layer such that ventilating air can only reach said at least one ventilating opening from the exterior opening by passing through the mesh layer
Implementation Method 2
The use of a mesh layer between the auxiliary layer and the shell permits snow and the like to be trapped between the mesh layer and the outermost layer for subsequent draining through the drain opening

AI summary
A ventilated garment includes a shell layer worn by the user and an auxiliary layer attached to a portion of shell to define a ventilated portion of the garment. An exterior opening formed in the outermost layer of the garment includes a fastener controlling the open or closed state of the exterior opening. A drain opening is also formed in the outermost layer separate from the exterior opening adjacent the bottom of the ventilated portion. Ventilating openings are formed in the waterproof innermost layer. A mesh layer spans the ventilating portion between the ventilating openings and the exterior opening to trap snow/rain and drain the precipitation through the drain opening therebelow to the exterior of the garment. The mesh layer blocks passage of precipitation therethrough while allowing a ventilating flow of air therethrough.
