Linked Round Carrying Bag Fastening Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing linked round carrying bags, such as those described in GB2489116, suffer from linked rounds pooling at the first end when not carried horizontally, making it difficult to access the rounds, especially when carried as a bandolier.
Innovation Solution
A linked round carrying bag with a fastening means positioned adjacent the opening, which tightly fastens around the outermost rounds to prevent pooling and ensure immediate access, utilizing quick release fastenings like hook and loop or press studs, and a flexible fabric sleeve made of Cordura, with a central zip closure and a triangular prism shape to facilitate easy removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the bag is carried as a bandolier without a fastening means, then the bag is easily accessible and simple to operate, but the linked rounds pool at the first end of the bag when not carried horizontally, making it difficult to access the rounds
Solution Approach 1:
The fastening means is engaged in advance to secure the linked rounds in position before the bag is carried or moved. This preliminary action prevents the rounds from pooling at the first end during transport, ensuring they remain accessible when needed without requiring additional adjustments during use.
Solution Approach 2:
The fastening means acts as an intermediary element between the bag and the linked rounds. It provides a mechanical connection that holds the rounds in the desired position within the bag, mediating between the bag's movement and the rounds' stability to prevent pooling while maintaining ease of access.
2Reliability
If a fastening means is added to the bag, then the linked rounds are held securely in position preventing pooling, but the device complexity increases
Solution Approach 1:
The fastening means is designed as a separate, extractable component that can be independently attached to the bag and engaged with the linked rounds. This separation allows the fastening function to be added without fundamentally redesigning the bag structure, maintaining simplicity while improving reliability.
Solution Approach 2:
The fastening means is positioned at a specific location within the bag (at the first end where rounds tend to pool) rather than distributing complexity throughout the entire bag structure. This localized approach provides the necessary stability function with minimal additional complexity.
3Reliability
If the fastening means is positioned away from the opening, then it provides general support for the rounds, but it does not prevent pooling at the first end and ensure immediate access to outermost rounds
Solution Approach 1:
The fastening means is positioned at the first end of the bag where rounds tend to pool, securing them in advance before use. This preliminary positioning ensures that when the bag is accessed, the outermost rounds are already in the correct position for immediate removal and use, combining support with accessibility.

AI summary
The present invention provides a linked round carrying bag (11) consisting of a flexible sleeve and a fastening means (20). The sleeve is sealed at a first end (12), has an opening at. a second end (9) and has an openable closure (1), for example a zip, extending substantially from the first end (12) to the second end (9), A width of the sleeve is greater than the length of an individual round of the linked round that the bag (11) is designed to carry but is less than twice the length of an individual round. The fastening means {20) is adjacent a closed side of a opening (14) of the: sleeve and is arranged to be tightly fastenable around the closed side of the opening (14) and any linked round carried in the bag, The bag (11) is advantageous as the fastening means (20) can ensure that a linked round is held in its proper position within the bag (11), even when the bag (11) is carried as a bandolier.
