Garment Patch Assembly for Replaceable Drawstring Closures
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional drawstrings in board shorts can become tangled or damaged during use or washing, necessitating the replacement of the entire garment.
Innovation Solution
A patch assembly is introduced to secure a drawstring to the garment, allowing for easy interchangeability and removability, featuring a panel with a loop and a retainer segment that can be frictionally or fastened to the drawstring.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional drawstring is integrated into the garment, then the fly closure function is achieved, but the drawstring becomes tangled or damaged during use or washing requiring entire garment replacement
Solution Approach 1:
The drawstring system is segmented into a permanent loop portion (integrated into the garment) and a removable drawstring portion (can be detached and replaced). This segmentation allows the durable loop to remain while the drawstring can be independently replaced if damaged or tangled, resolving the contradiction between durability and ease of repair.
Solution Approach 2:
The removable drawstring portion can be discarded when damaged and a new one can be recovered or inserted into the permanent loop. This principle allows replacement of only the damaged component rather than the entire garment, improving both reliability and ease of repair.
2Reliability
If the drawstring is permanently attached to the garment, then the fly closure remains secure, but the drawstring cannot be easily replaced when damaged
Solution Approach 1:
The fly closure system is segmented into a permanent loop attachment (ensuring security) and a removable drawstring portion (enabling easy replacement). The loop remains permanently attached to maintain fly closure security, while the drawstring portion can be easily removed and replaced when needed.
Solution Approach 2:
The drawstring system transitions from a static permanent attachment to a dynamic system where the drawstring portion can be inserted or removed from the loop as needed. This dynamic capability maintains security during use while enabling easy replacement when damaged.
3Reliability
If the entire garment is replaced when the drawstring is damaged, then a functional fly closure is restored, but material waste and cost increase
Solution Approach 1:
The garment is segmented into the valuable permanent loop portion and the replaceable drawstring portion. When the drawstring is damaged, only the drawstring portion needs replacement rather than the entire garment, preventing material waste and reducing cost while restoring fly closure functionality.
Solution Approach 2:
Instead of discarding the entire garment when the drawstring is damaged, only the damaged drawstring portion is discarded and a new one is inserted. This selective replacement minimizes material waste and extends the usable life of the garment while maintaining fly closure functionality.
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 patch assembly prolongs the life of the garment by preventing damage to the drawstring, enabling easy replacement and maintenance of the fly closure.
Implementation Method 1
the retainer segment can be a frictioned surface adhered to the drawstring

AI summary
Drawstrings in garments can become easily damaged during use in sports or within washing machines, rendering the entire garment useless. Garments with an easily detachable/replaceable drawstring provide an economical solution to allow laundering the garments without the drawstring, thereby extending the lifetime of the garment and increasing variability of design through the use of interchangeable replacement drawstrings.
