Hood Fastener Positioning for Jacket Back Storage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hooded jacket designs require runners to stop and manually fold or roll up the hood to fasten it, making it difficult to store the hood while running, especially in cold environments or during races, and often fail to adequately restrain hood flapping and noise in windy conditions.
Innovation Solution
A hooded jacket with a hood fastener positioned on the back at a predetermined distance from the neckline, allowing the hood to be easily passed through and fastened with minimal interruption to running, using a band-shaped rubber member with stretchability and anti-slip treatment to secure the hood in place.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a hood lock system is provided at the neckline to fold and fasten the hood, then the hood can be restrained from flapping, but the runner must pause and stop to take off the jacket to fold the hood
Solution Approach 1:
The hood fastener is relocated from the traditional neckline (front/dimensions near the head) to the back of the jacket, creating a new spatial dimension for fastening. This allows the hood to be secured at the back without requiring the runner to stop or remove the jacket, as the fastening action can be performed continuously during running.
Solution Approach 2:
The hood is pre-positioned to hang down the back of the jacket body, with the unrestrained portion extending from the neckline to the fastener. This preliminary arrangement allows the hood to be quickly secured by simply passing it through the fastener without requiring complex folding or manipulation, enabling continuous use during running.
2Ease of operation
If a complicated structure is employed to enable hood storage while running, then the hood can be fastened without stopping, but the manufacturing cost increases
Solution Approach 1:
The fastener is positioned at a specific distance from the neckline (one-fourth to three-fourths of the hood length) to optimize both functionality and simplicity. This parameter optimization allows the hood to be effectively restrained while maintaining a simple structure that does not increase manufacturing cost.
Solution Approach 2:
The hood is divided into two functional segments: the unrestrained portion (from neckline to fastener) that remains free for quick access, and the restrained portion (below the fastener) that is secured to prevent flapping. This segmentation enables simple yet effective hood management during running.
3Reliability
If the hood fastener is positioned close to the neckline, then the unrestrained portion is short, but the hood cannot be easily accessed when needed
Solution Approach 1:
The fastener position is optimized to be located at one-fourth to three-fourths of the hood length from the neckline, creating an optimal balance. This ensures the unrestrained portion is sufficiently long for easy access and manipulation, while the restrained portion is sufficiently long to effectively prevent hood flapping in windy 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
Enables seamless storage and restraint of the hood while running, preventing flapping and noise, without the need to stop or remove the jacket, and allows easy retrieval of the hood for use, while maintaining a simple and cost-effective design.

AI summary
In a hooded jacket (10), a hood (12) and a jacket body (11) are provided, and a hood fastener (20) fastens the hood (12) not in use, at a position spaced away from a neckline toward the back by a certain length such that the certain length from the neckline of the hood (12) hanging down the back of the jacket body (11) becomes an unrestrained portion. In the hood fastener (20), at least left and right ends are attached to the back of the jacket body (11), and passing the hood (12) not in use between the left and right ends enables fastening the hood (12) to the back of the jacket body (11). The hood fastener (20) is provided at a position away from the neckline toward the back, by a distance in the range of 1/2 to 3/4 of a length from the neckline to the tip of the hood (12) hanging down the back of the jacket body (11).
