Foldable Backpack Frame Assembly for Stable Upright Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Backpacks, due to their design and deformation from carrying contents, cannot be set down in an orderly manner, making it difficult to access their contents without changing their position, and there is currently no effective solution for their functional setup.
Innovation Solution
A two-part frame construction with U-shaped parts and articulated connections that allows the backpack to be securely attached and positioned, enabling easy access to its contents without changing its position, and can be folded for space-saving storage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If backpacks are designed to be adaptable to the wearer and accommodate contents, then comfort and utility are improved, but the backpack deforms and cannot be set down in an orderly manner
Solution Approach 1:
The backpack is divided into two functional parts: a rigid frame structure that maintains shape and an inner bag that accommodates deformable contents. The frame segments (front frame part and rear frame part) work together to preserve the backpack's external shape while allowing the contents to be adaptable and deformable.
2Adaptability or versatility
If backpacks are made flexible to accommodate contents, then utility is improved, but access to contents requires changing the backpack's position
Solution Approach 1:
The frame structure incorporates articulated connections that allow dynamic adjustment between a carried state and a set-down state. When set down, the articulated connections position the opening at the top, enabling easy access to contents without requiring the user to pick up or reposition the backpack.
3Shape
If a rigid structure is used to maintain backpack shape, then orderly setting down is improved, but the structure cannot be folded for storage
Solution Approach 1:
The frame structure uses articulated connections between the front frame part and rear frame part, allowing the rigid structure to dynamically fold into a compact configuration for storage while maintaining its rigid, shape-defining function when assembled and used.
4Reliability
If the backpack structure is made stable for carrying, then reliability is improved, but the structure cannot be easily folded for storage
Solution Approach 1:
The articulated connections provide a dynamic solution that delivers stable, reliable support during carrying through the rigid frame configuration, while enabling easy folding into a compact form for storage when not in use.

AI summary
The invention describes a stand-up arrangement for backpacks after wearing. FIG. 1 shows a two-part frame construction. One part (1) is designed in such a way that the backpack with the shoulder straps can be easily attached to parts (5) designed in a U-shape. The other part (2) is connected to one part (1) via articulated connections (3) with angle limits (4) and thus forms a support so that the frame construction is secured against falling over. So that the backpack attached here can assume a defined position, a cross brace (7) is attached to the other part (2) of the frame construction via articulated connections (8), which acts as a one-sided stop for the backpack. After use, the frame construction can be folded together using the articulated connections (3.8) and is therefore easy and space-saving to park.
