Drawstring Closure for Board Shorts Fly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional board shorts with fasteners like zippers, snaps, and gussets face issues such as bulkiness, aesthetic problems, and discomfort due to bulk at the fly area, and lack secure closure, especially during active use like surfing.
Innovation Solution
A drawstring closure system with two separate laces attached to the waistband, providing horizontal oppositional force for secure and even tightening, and incorporating gasketed eyelets for fixation, eliminating the need for fasteners and enhancing privacy with a facing strip.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional fasteners (zippers, snaps, buttons) are used to close the fly, then the fly can be securely closed, but the garment bulk and aesthetic appearance deteriorate due to seams and fastener extensions
Solution Approach 1:
The patent removes conventional fasteners (zippers, snaps, buttons) and their associated seams from the fly area, extracting the problematic elements while retaining closure functionality through drawstrings that pass through eyelets without requiring attachment seams
Solution Approach 2:
The closure system is segmented into separate functional elements: drawstrings for tightening, eyelets for guidance, and optional tabs for positioning, allowing each component to be optimized independently and reducing overall bulk
2Reliability
If a gusset is used to interconnect the two sides of the fly, then the fly can be kept closed, but the garment bulk and convenience of donning deteriorate
Solution Approach 1:
The patent eliminates the gusset entirely, removing the fabric shield that interconnected the two sides of the fly, thereby eliminating the bulk and operational inconvenience while maintaining closure security through the drawstring system
3Reliability
If conventional fasteners are used throughout the entire length of the fly, then the fly can be securely closed, but the aesthetic appearance deteriorates due to bulk and seam visibility
Solution Approach 1:
The patent removes conventional fasteners and their associated seams from the fly area, extracting the problematic elements that compromised aesthetic appearance while retaining closure functionality through drawstrings that pass through eyelets without requiring attachment seams
Solution Approach 2:
The drawstring system provides localized closure control at specific points (eyelets) rather than requiring continuous fastening along the entire fly length, allowing the fly to lie flat and neat in the closed position while maintaining security
4Reliability
If closure systems are used in board shorts for surfing, then the fly can be kept closed, but the comfort deteriorates when laying on the surfboard
Solution Approach 1:
The patent removes conventional fasteners and gussets that created bulk and discomfort in the fly area, extracting elements that caused harmful discomfort when laying on a surfboard while maintaining closure security through the streamlined drawstring system
