Dynamic Venting Garment Actuated by Arm Movement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sports garments with static venting elements fail to provide optimal airflow during sporting activities while being unnecessary and inefficient when not in use, lacking adaptability to user preferences and varying arm lengths.
Innovation Solution
The garment features actuating means connected to the arm sleeve with adjustable thumbholes and varying stiffness edges for the venting elements, allowing controlled airflow through the arm movement, enhancing airflow during sports and maintaining normal properties when not in use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a static venting element with a fixed opening is provided in the garment, then airflow during sporting activities is improved, but the garment loses its normal appearance and functionality when not in use
Solution Approach 1:
The venting element transitions from a static opening to a dynamic structure that opens and closes based on arm movement. The actuating means connected to the arm sleeve enable the venting element to dynamically adjust its state between closed (normal appearance) and open (airflow during sports) configurations.
2Temperature
If a large venting opening is provided for optimal cooling during sports, then convection is improved, but the garment is unnecessarily compromised when not used for sports
Solution Approach 1:
The venting element dynamically adjusts its opening size based on activity level. During sports, arm movements activate the actuating means to open the venting element for optimal cooling. When not in use, the venting element remains closed, maintaining the garment's normal appearance and functionality.
3Productivity
If the venting element is always open for maximum airflow, then cooling during movement is improved, but the garment cannot maintain normal appearance when not in use
Solution Approach 1:
The venting element's state is dynamically controlled by arm movement through the actuating means. During sporting activities, the venting element opens to provide cooling. When the garment is worn casually without arm movement, the venting element remains closed, preserving the garment's normal appearance.
4Device complexity
If a static venting element is provided, then the structure is simple, but it cannot adapt to different usage conditions and user preferences
Solution Approach 1:
The venting element incorporates dynamic actuation through the arm sleeve connection. This allows the relatively simple structure to adapt to different usage conditions automatically - opening during sports activities and closing during casual wear - providing versatility without significant structural complexity.
Solution Approach 2:
The actuating means utilize the wearer's own arm movements to automatically control the venting element's opening and closing. The system self-regulates based on natural body motion during sports activities, eliminating the need for external controls or complex mechanisms while adapting to user preferences and usage conditions.
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
This design optimizes airflow during sports activities, improving cooling through increased convection and user-adjustable tension transfer, ensuring efficient ventilation without unnecessary openings when not in use.
Implementation Method 1
the actuating means affect one of the edges of the venting element perpendicular to the edge which has in general beneficially a longitudinal extension
Implementation Method 2
allowing an air flow to flow from the outside of the garment through the section into the inner of the garment for cooling a part of the body of the wearer

AI summary
The invention relates to a garment (1), especially a sports garment, having a section (2) which at least partially covers the body of a wearer, wherein the section (2) has at least one venting element (3) for allowing an air flow (F) to flow from the outside of the garment (1) through the section (2) into the inner of the garment (1) for cooling a part of the body of the wearer. To improve the cooling during the movement of the wearer of the garment the invention proposes that actuating means (4) are arranged for opening and closing the venting element (3) in dependence of the movement of a part of the body of the wearer during the use of the garment (1).
