Rail-Mounted Bag With Helical Belt Segments
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing swivelable bags often face difficulties in rotating relative to the user due to belt stiffness, especially when transitioning from a rear to a front carrying mode, as the belt may not easily swivel around the user's body.
Innovation Solution
A rail-mounted bag system with a flexible strap and helical belt rail segments allows the bag to slide smoothly along a helical core, utilizing clip-shaped rail carriages and fabric loops for secure attachment, enabling effortless rotation from rear to front carrying modes without requiring the belt to move relative to the user's body.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a traditional belt is used to mount the bag, then the bag can be worn in various orientations, but the belt has difficulty swiveling relative to the user due to stiffness
Solution Approach 1:
The belt is divided into multiple rigid rail segments connected by flexible elements, allowing the belt to maintain structural integrity while enabling swiveling motion through the segmented construction
Solution Approach 2:
The belt combines rigid plastic rail segments with flexible fabric or webbing materials, creating a composite structure that provides both the necessary stiffness for support and the flexibility for swiveling motion
2Strength
If the belt is made stiff to support the bag, then the bag can be securely carried, but the belt cannot easily rotate around the user's body
Solution Approach 1:
The belt is segmented into rigid rail sections that provide structural support and flexible connection sections that enable rotation, allowing the system to simultaneously achieve strength and rotational ease
Solution Approach 2:
The belt transitions from a static rigid structure to a dynamic segmented structure that can adapt its rigidity, maintaining strength when needed while allowing rotation through the flexible connections between segments

AI summary
A rail mounted bag has a bag. The bag is hollow and configured to store articles. A strap is made of fabric material, flexible and elongated. A rail is mounted on the strap. The rail is mounted to face the bag. A rail carriage is connected to the bag and slidingly connected to the rail. The bag is configured to slide along the rail. The rail is formed of belt rail segments with rail gaps between each of the belt rail segments. The rail is formed as a helix around a helical core. The helical core is an elongated opening parallel to the helix. Each turn of the helix is a rail segment. The bag also optionally includes a rail carriage loop mounted to a bag rear. The rail carriage is mounted to the rail carriage loop.
