Adjustable Pouch Nonelastic Strap Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing adjustable pouches with elastic binding cords suffer from items flopping around due to excessive flex, and often have design flaws that hinder quick insertion and removal, as well as gaps that cause snagging issues.
Innovation Solution
A nonrigid adjustable pouch design featuring a U-shaped inner and outer sheet arrangement with non-elastic straps and a binding cord system that allows for adjustable expansion and contraction, along with hook and loop connectors and molle slots for secure item retention and easy access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If elastic binding cords are used to interconnect front and rear portions of the pouch, then adjustability and conformability are improved, but excessive flex causes items to flop around and fall out
Solution Approach 1:
The binding system is divided into multiple independent straps (typically three) that can be individually adjusted and secured. Each strap operates independently to provide stability while maintaining adjustability, preventing the flopping issue by distributing support across multiple segmented elements rather than relying on a single continuous elastic cord.
Solution Approach 2:
The pouch employs a dynamic adjustment mechanism where straps can be easily tightened or loosened via quick-release buckles or similar fastening systems. This allows the pouch to adapt its configuration based on the size and shape of items being carried, providing both adjustability and stability without requiring the entire binding system to be elastic.
2Reliability
If the top opening of the pouch is designed for secure closure, then item retention is improved, but insertion and removal of items becomes difficult
Solution Approach 1:
The pouch incorporates pre-formed openings or access points at the top that are designed to accommodate common item shapes (such as magazine wells or radio compartments). These pre-configured access points allow items to be quickly inserted or removed without requiring the user to manipulate complex closure mechanisms, while the rest of the pouch remains securely closed.
Solution Approach 2:
The top opening is segmented into multiple access points or compartments rather than a single continuous opening. This allows different items to be accessed independently through specific openings, maintaining secure closure of the entire pouch while enabling rapid insertion and removal of individual items through dedicated access points.
3Adaptability or versatility
If gaps are left along the sidewalls for flexibility, then conformability is improved, but items can catch on the binding cord causing snagging issues
Solution Approach 1:
The pouch utilizes flexible side walls made from thin, pliable material that can conform to the shape of carried items without creating protruding edges or gaps. This flexible shell approach allows the pouch to adapt its shape while maintaining a smooth surface that prevents items from catching or snagging on rigid structures or binding cords.
Solution Approach 2:
The binding system is extracted from the traditional elastic cord configuration and repositioned to the rear or bottom portions of the pouch, away from the sidewalls and top opening areas where items are inserted and accessed. This extraction eliminates the snagging hazard while preserving the flexibility and conformability needed for the pouch to adapt to different item shapes.

AI summary
An adjustable pouch comprising a nonrigid inner sheet folded in a generally U-shaped arrangement defining a front side and a rear side connected by a bottom portion; a nonrigid outer sheet secured around an outer surface of said inner sheet; a plurality of strap receiving channels extending between said inner sheet and said outer sheet on said rear side; a plurality of non-elastic nonrigid straps extending outward from a perimeter edge of said outer sheet on said front side, wherein said straps are received in said strap receiving channels; a binding cord interconnecting a distal end portion of each said strap between said inner sheet and said outer sheet; a first sidewall insert carried by said straps on a first side; and, a second sidewall insert carried by said straps on a second side opposite said first side.
