Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing clothing ventilation systems do not adapt to the user's physical activity or body morphology, leading to inadequate air flow regulation and discomfort during varying physical activities.
Innovation Solution
A ventilation zone with interconnected strips of higher air permeability, oriented vertically or at an angle, and elastic means that adjust air permeability based on user movement, integrating with the garment's panels to enhance ventilation and comfort.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If ventilation channels are continuously formed to allow air circulation, then the drying of wet zones is improved, but the thermal insulation is reduced when the user needs to maintain body temperature
Solution Approach 1:
The ventilation channel's air permeability is made dynamic through the elastic closure element that can transition between open and closed states. The elastic element responds to user movement and pressure changes, automatically adjusting the ventilation opening to provide either air circulation for drying or thermal insulation as needed.
Solution Approach 2:
The air permeability parameter of the ventilation channel is changed by the elastic closure element which modifies the effective opening area. When the closure element is in one position, the channel is open for high permeability; when in another position, it closes to reduce permeability, thus adapting to different thermal conditions.
2Ease of operation
If ventilation openings are made controllable by voluntary gesture (e.g., zipper manipulation), then the air flow regulation is improved, but the device complexity is increased
Solution Approach 1:
The elastic closure element functions as a self-actuating mechanism that responds automatically to user movement and pressure changes. Instead of requiring voluntary manipulation of a zipper or other complex control, the system uses the user's own movements to open or close the ventilation channel through the elastic element's responsive behavior.
Solution Approach 2:
The complex mechanical zipper system is replaced with a simpler elastic closure element that uses elastic deformation and pressure response to control ventilation. This substitution reduces mechanical complexity while maintaining ease of operation through intuitive movement-based control.
3Ease of manufacture
If fixed ventilation openings are used, then the manufacturing is simplified, but the adaptability to different physical activities and body morphology is reduced
Solution Approach 1:
The ventilation channel incorporates dynamic elements (elastic closure element and stress-responsive strips) that allow the opening to change its configuration based on user movement and body morphology. This maintains manufacturing simplicity while achieving adaptability through movement-based control of the elastic component.
Solution Approach 2:
The effective opening area and air permeability parameters of the ventilation channel are made variable through the elastic closure element. The system transitions between different permeability states based on user activity level and body shape, providing adaptability without complex adjustable mechanisms.
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 system dynamically regulates air flow according to physical activity, improving ventilation and thermal insulation while conforming to the user's body shape, enhancing comfort and air circulation.
Implementation Method 1
The first ventilation zone comprises an elastic means making it possible to bring the strips together when the side edges of the first ventilation zone are not stressed
Implementation Method 2
The first ventilation zone comprises at least three strips interconnected by junctions having greater air permeability than at the level of the strips
Implementation Method 3
When the user performs a physical activity, for example respiratory or muscular activity, he will stress the side edges of the first ventilation zone. Consequently, these stress variations coupled with the elastic means will make it possible to modify the air permeability of the first ventilation zone.

AI summary
A garment (1) intended to cover the torso of a user, comprising at least one first ventilation zone (5) positioned on an anterior (21) or posterior (31) thoracic part of the garment, the first ventilation zone forming part of a front (22) or rear (33) panel of the garment, the first ventilation zone comprising at least three straps (51) connected by junctions (52) having greater air permeability than at the straps, the straps being oriented in a vertical direction (Z) or inclined at an angle of plus or minus 45 degrees to a vertical axis so that each strap converges towards the bottom of the garment. The first ventilation zone includes elastic means (52, 54) for bringing the straps together when the lateral edges of the first ventilation zone are not under stress.
