Hood Drawstring Channel for Even Temporal Region Tightening
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hood designs for clothing, such as raincoats and cold weather gear, face difficulties in evenly tightening the hood opening and temporal region, leading to inadequate fitting when using a drawstring mechanism.
Innovation Solution
A hood design featuring a drawstring channel with distinct portions along the upper and lower edges of the hood opening, including a third portion extending rearward, allows for separate adjustment of the hood opening and temporal region through a guide with a hook portion and an adjuster on the backside, enabling simultaneous and even tightening.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a single drawstring is extended through the temporal region to cinch both the hood opening and temporal region, then the operation is simple, but the tightening is uneven with the hood opening being over-cinched and the temporal region under-cinched
Solution Approach 1:
The drawstring is divided into two separate strings: a first string threaded through the second portion (lower peripheral edges) and a second string threaded through the first portion (upper peripheral edges) and third portion (temporal region). This segmentation allows independent control of tightening forces applied to different regions of the hood, resolving the uneven tightening problem while maintaining simple operation through a single adjuster mechanism.
2Device complexity
If the drawstring is positioned only along the peripheral edge of the hood opening, then the structure is simple, but the temporal region cannot be adequately cinched
Solution Approach 1:
The drawstring channel is extended from the traditional two-dimensional path along the hood opening perimeter into a three-dimensional configuration by adding the third portion that projects forward along the temporal region. This dimensional extension enables the drawstring to access and cinch the temporal region without significantly increasing overall structural complexity, as the channel follows the natural contours of the hood body.

AI summary
Provided is a hood (10) for clothing whose opening (20) and a temporal region may be easily fitted to a wearer with a simple operation. A hood (10) in one embodiment includes a hood body (12) having a drawstring channel (22). The drawstring channel (22) includes a first portion (22A) that extends in the substantially vertical direction along left and right peripheral edges respectively of an upper portion of an opening (20), and a second portion (22B) that is coupled to a lower end of the first portion (22A) and extends in a substantially front-rear direction on left and right sides of the hood (10). The hood (10) further includes a first string (14) that is threaded through the drawstring channel (22), and an adjuster (18) that is provided on a back side of the hood body (12) for adjusting a length of the first string (14) in accordance with operation of the adjuster (18) by a user. In the hood body (12), a hook catching portion (24) that has a through hole (24A) is provided in the drawstring channel (22). The first string (14) is threaded through the through hole (24A) of the hook catching portion (24). A hook portion (26) that is configured to be caught by the hook catching portion (24) is formed in the first string (14) at a position in the first portion (22A) before the hook catching portion (24).
