Foldable Sling-Backpack Structure for Capacity and Compartments
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing combination-style bags often sacrifice capacity or lack sufficient functional compartments, making them inadequate for both casual and heavy-duty use scenarios.
Innovation Solution
A combination bag design that integrates a single-shoulder sling bag with a double-shoulder backpack, featuring a foldable bag body with a rigid support structure, allowing the sling bag to unfold within the backpack, thus exposing its pockets and compartments, and maintaining ample storage space for the backpack.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a combination-style bag integrates both single-shoulder sling bag and double-shoulder backpack elements, then versatility and adaptability are improved, but the capacity and number of functional compartments are reduced
Solution Approach 1:
The sling bag is nested within the backpack interior space when not in use, allowing the backpack to maintain its full capacity while the sling bag components are stored inside. This nesting approach resolves the contradiction by enabling both bag modes to coexist without permanently sacrificing backpack capacity.
Solution Approach 2:
The bag structure is designed to be dynamically reconfigurable, allowing users to switch between backpack-only mode, sling bag-only mode, and combined mode. The flat-shaped bag body can be folded or unfolded to transform the bag's configuration, providing adaptability while maintaining full capacity in each mode.
2Adaptability or versatility
If a combination-style bag integrates both single-shoulder sling bag and double-shoulder backpack elements, then versatility and adaptability are improved, but the number of functional compartments and pockets is reduced
Solution Approach 1:
The bag features dynamically reconfigurable compartments that can be accessed or concealed based on the current mode. When the sling bag is unfolded and worn, its pockets and compartments become accessible; when folded into the backpack, they are stored away, maintaining full functionality in each mode without permanent compromise.
Solution Approach 2:
The bag is segmented into distinct functional zones - the backpack compartments remain permanently accessible, while the sling bag compartments are integrated but can be independently accessed when needed. This segmentation allows both sets of compartments to function without interfering with each other.
3Adaptability or versatility
If the sling bag component is integrated into the backpack, then adaptability is improved, but the backpack's storage space is reduced
Solution Approach 1:
The sling bag is designed to nest within the backpack's interior space when not in use, utilizing otherwise wasted space. This allows the backpack to maintain its full storage capacity while accommodating the sling bag components, resolving the space reduction issue.
Solution Approach 2:
The sling bag features a flat-shaped, flexible bag body that can be folded into a thin profile for storage within the backpack. This flexible design allows it to occupy minimal space when not in use while providing sufficient volume when unfolded and worn.

AI summary
A combination bag, includes a sling bag and a backpack with an interior space, wherein the sling bag includes: a flat-shaped and foldable bag body with a first surface and a second surface, a rigid support structure embedded within the flat-shaped bag body, symmetrically arranged along a fold line of the flat-shaped bag body; a shoulder strap attached to the flat-shaped bag body; at least two bag components positioned on the second surface of the flat-shaped bag body, for forming an independent storage compartment; and the interior space is defined by a first wall, a second wall opposite the first wall, and a continuous side wall connecting the first and second walls; wherein the first wall has an area approximately equal to that of the flat-shaped bag body, and flat-shaped bag body is detachably fixed and close contacted with the first wall by a connecting component.
