Woven Hat Drawstring Layout for Long-Lasting Tension Hold
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing headwear, such as hats, struggle to maintain a secure and comfortable fit for extended periods, especially in windy conditions, due to the inability to evenly distribute tension over time without relying on additional securing means like headbands or sweatbands.
Innovation Solution
A system comprising a semi-rigid weave layer with specific openings and a pliable drawstring or cord configuration that allows for secure and adjustable fitting, where the drawstring is woven through strategically placed openings to maintain tension without the need for additional fastening mechanisms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a simple drawstring is used to adjust hat size, then the hat is easy to adjust and ventilated, but the drawstring cannot maintain tension for extended periods greater than 30 minutes
Solution Approach 1:
The drawstring system transitions from a static single-pass configuration to a dynamic multi-pass configuration that adapts over time. The cord weaves through multiple openings (at least 4 openings) in the hat body, creating overlapping segments that progressively engage and maintain tension. This dynamic weaving pattern allows the system to evolve from initial adjustment to sustained tension maintenance over extended periods.
Solution Approach 2:
The drawstring configuration moves from a simple linear path to a multi-dimensional weaving pattern through the hat structure. By passing through multiple openings at different locations and creating overlapping segments, the system adds spatial complexity that transforms the tension distribution across multiple dimensions, enabling sustained tension maintenance.
2Reliability
If additional securing means like headbands or sweatbands are added, then the hat remains secure in place, but the device complexity increases
Solution Approach 1:
The drawstring cord serves multiple functions simultaneously: it adjusts the hat size, secures the hat to the wearer's head, and maintains tension for extended periods. By making the single cord multi-functional, the invention eliminates the need for separate headbands or sweatbands, reducing overall device complexity while maintaining or improving security of fit.
Solution Approach 2:
The invention merges the functions of adjustment and securing into a single integrated drawstring system. Instead of having separate components for size adjustment and for securing the hat, the cord performs both functions through its multi-pass configuration, combining multiple roles into one element and thereby reducing complexity.
3Duration of action of stationary object
If the drawstring is woven through multiple openings with overlapping segments, then tension is maintained for extended periods, but the manufacturing precision requirements increase
Solution Approach 1:
The drawstring system is divided into multiple discrete segments that pass through separate openings in the hat body. By segmenting the cord path into distinct sections (with at least 4 openings and overlapping segments), the system distributes the tension maintenance function across multiple independent points, reducing the precision required at any single location while achieving overall sustained tension.
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 effectively secures headwear in place for extended periods by utilizing the frictional contact of overlapping cord segments, ensuring stability and comfort without requiring knots or additional securing devices.
Implementation Method 1
The subject invention concerns a wearable article, e.g., an article of clothing, preferably headwear, such as a hat or cap, that is free of an inner headband or sweatband, and a system for securing the article to the body... The cord can be press-fittingly woven through two front openings in the weave layer... About one inch of the middle segment of the cord is positioned on an inner surface of the weave layer... The first and second ends of the drawstring or cord are woven through the back openings in opposite directions... whereby the first and second ends of the drawstring or cord, and the sub-segments of the drawstring or cord adjoining each of the first and second ends extend outwardly from the outer surface of the weave layer

AI summary
A system for providing a drawstring for an article of clothing or accessory having a front and a back and having a peripheral surface necessary to be tightened, the system including a semi-rigid weave layer having a braided strands of a fibrous material defining a pattern in the article having openings which repeat at a number in a range of about 3 to about 8 per linear inch in all directions, and in which the openings of the layer define a range of between about 15 to about 35 percent of the entire surface of the weave layer and a cord braided of filaments of a material more pliable than the braided strands of the weave layer.
