Backpack With Flexible Dividers For Fragile Item Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing shopping bags and backpacks are cumbersome and inefficient for transporting items of varying fragility and weight, often requiring complex designs with additional containers that complicate loading and storage.
Innovation Solution
A backpack with flexible, non-self-supporting material compartments, adjustable straps, and a versatile opening mechanism allows easy loading and storage of heavy and fragile items, featuring dividers and a lid for organized compartment access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a rigid storage container is added to protect fragile items, then protection of fragile items is improved, but device complexity increases and the bag cannot be folded or rolled up
Solution Approach 1:
The patent uses flexible dividers made of fabric, tarpaulin, plastic, or foam material that can be rolled or folded, replacing rigid containers. These flexible partitions provide protection for fragile items while maintaining the ability of the bag to be compacted for storage.
Solution Approach 2:
The patent divides the bag interior into multiple receiving areas using flexible dividers, creating separate compartments for different items. This segmentation protects fragile items without requiring a single rigid container, thus reducing overall device complexity.
2Reliability
If a rigid storage container is added to protect fragile items, then protection of fragile items is improved, but ease of operation deteriorates due to additional opening requirements
Solution Approach 1:
The flexible dividers serve multiple functions: they protect fragile items, create separate receiving areas for organization, and can be configured in various ways. The single main opening serves all compartments, eliminating the need for additional specialized openings.
3Stability of the object's composition
If heavy items are placed at the bottom, then stability is improved, but fragile items above are crushed
Solution Approach 1:
The patent segments the backpack interior into multiple receiving areas using flexible dividers, creating distinct compartments for heavy and fragile items. This allows heavy items to be placed at the bottom in one compartment while fragile items are protected in separate compartments above, preventing crushing while maintaining stability.
4Ease of operation
If the backpack is made from flexible, non-self-supporting material, then ease of storage is improved by allowing folding or rolling, but structural strength deteriorates
Solution Approach 1:
The patent uses flexible, non-self-supporting materials such as fabric, tarpaulin, plastic, or foam that can be rolled or folded for compact storage. The structural strength is maintained through the overall backpack framework and the tensioning system of straps and buckles that provide support when worn.
Solution Approach 2:
The backpack transitions from a flexible, compact state for storage to a supported, load-bearing state when worn. The carrying straps and buckles dynamically engage to provide structural strength during use, while allowing the material to remain flexible for storage.

AI summary
The invention relates to a backpack (9) for transporting light and heavy goods. The backpack comprises a body (10) for holding items and at least one carrying strap (19) for carrying the backpack (9) on the shoulders of a wearer. The body (10) comprises: - a top (11), which is positioned at the top in a carrying position; - a bottom (12) opposite the top (11); - two side sides (13; 14), which connect the top (11) and the bottom (12) of the body (10) and are arranged opposite each other; - a back side (15), which connects the side sides (13; 14), the top (11), and the bottom (12) and is positioned against the wearer's back in the carrying position; and - an outer side (16) opposite the back side (15), which is designed, in particular, as a lid that closes the loading opening (17) for loading the backpack (9).The carrying strap (19) is connected to the body (10) at at least two points, so that the back (15) of the body (10) can rest against the back of a wearer in a carrying position. The body (10) comprises at least two separating elements (18) which divide the interior of the body (10) into different receiving areas (5a-5c), such that in the carrying position the receiving areas (5a-5c) are arranged essentially one above the other and the body (10) and the separating elements (18) are made of flexible material.
