Quick Release Bag Assembly with Pull Tab Fastener
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bag designs require a two-step process to retrieve items, which can be time-consuming, especially in emergency situations, as they necessitate opening the bag and then reaching inside to retrieve the item.
Innovation Solution
A quick release assembly with a bag featuring a fastener system comprising a first and second fastening element, along with a pull tab that allows for the secure storage and one-step removal of a material organizer by detaching the coupling between the fastening elements when pulled.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a traditional closed-loop fastener system is used to secure items in a bag, then secure storage is achieved, but retrieval time increases due to requiring two steps (opening the pouch and retrieving the item)
Solution Approach 1:
The fastener system is segmented into two independent fastening elements: a first fastening element on the pouch and a second fastening element on the belt loop. This segmentation allows the pouch to be opened independently from the belt loop, enabling direct access to items without removing the pouch from the belt, thus reducing retrieval time while maintaining secure storage when closed
Solution Approach 2:
A belt loop serves as an intermediary component that connects the pouch to the user's belt while providing a separate fastening mechanism. The belt loop with its integrated fastening element allows the pouch to remain secured to the belt during normal wear, but enables quick access by simply opening the pouch flap without disrupting the belt attachment
2Reliability
If a traditional closed-loop fastener system is used, then secure storage is maintained, but device complexity increases due to requiring multiple components (pouch, belt loop, fastening elements)
Solution Approach 1:
The belt loop is merged with a fastening element integrated directly into the belt loop structure. This combination eliminates the need for separate buttons, snaps, or other fastening mechanisms that would typically be attached to both the pouch and the belt, thereby reducing the total number of components while maintaining secure attachment
Solution Approach 2:
The belt loop serves multiple functions: it attaches the pouch to the user's belt, provides structural support, and incorporates a fastening element that works with the pouch's fastening system. This multi-functionality reduces the need for separate dedicated components for each function, simplifying the overall device structure

AI summary
Quick release assembly comprises a bag and a material organizer. The bag defines an opening flap and a fastener. The fastener includes a first fastening element provided on the opening flap and a second fastening element provided on a side wall of the bag. The second fastening element removably couples with the first fastening element. The material organizer is received within the bag and defines a pull tab that extends from the material organizer to outside of the bag. The pull tab defines an aperture sized for the first fastening element to pass therethrough for detachably coupling with the second fastening element to form a closed configuration of the bag, thereby securing the material organizer within the bag. Pulling the pull tab detaches the coupling between the first and second fastening elements.
