Backpack Carrying System with Diagonal Straps and Modular Connectors
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing backpack carrying systems face difficulties in putting on and taking off, particularly in acute situations, and often result in incorrect loading and restricted mobility due to inadequate ergonomic design and permanent strap connections.
Innovation Solution
A backpack with an ergonomic back plate and diagonally extending carrying straps, featuring connecting and fastening bodies for rapid attachment and detachment, along with adjustable straps to distribute weight and improve fit, and optional inflatable air ducts for enhanced comfort and pressure adjustment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If permanent connection straps are used, then the backpack structure is simple and reliable, but it becomes difficult to put on and take off rapidly
Solution Approach 1:
The carrying system is divided into modular components: a back plate, multiple independent carrying straps (upper and lower), and detachable connecting bodies. This segmentation allows the straps to be independently adjusted and quickly connected or disconnected from the back plate, enabling rapid donning and doffing while maintaining structural reliability through the organized modular assembly.
Solution Approach 2:
The connecting bodies are designed to be detachable rather than permanent, transforming the static connection into a dynamic one. The connecting bodies can be quickly attached to and detached from the back plate, allowing the carrying system to transition between secured and released states, thus solving the contradiction between reliable structure and ease of operation.
2Ease of operation
If traditional shoulder straps are used, then the backpack is easy to put on, but it causes incorrect loading and restricted mobility
Solution Approach 1:
The carrying straps are arranged in multiple spatial dimensions and orientations. Upper carrying straps extend diagonally across the chest, while lower carrying straps wrap around the waist and hips. This multi-dimensional strap arrangement distributes weight across different body regions (shoulders, chest, waist, hips), correcting loading posture and enhancing mobility without compromising ease of donning.
3Device complexity
If non-adjustable straps are used, then the backpack structure is simple, but it causes chafing and incorrect weight distribution
Solution Approach 1:
The carrying straps incorporate adjustable elements that allow dynamic modification of strap length and tension. Users can adjust the upper carrying straps to achieve proper diagonal positioning across the chest and modify lower carrying straps to fit securely around the waist and hips. This adjustability prevents chafing and ensures correct weight distribution while maintaining relatively simple strap structures.
Solution Approach 2:
Different regions of the body receive customized strap configurations. Upper carrying straps are positioned to distribute weight across the shoulders and chest, while lower carrying straps are positioned around the waist and hips. The connecting bodies are positioned at specific locations on the back plate to optimize the geometric arrangement of straps, creating locally optimized load distribution across different body regions.

AI summary
The present invention concerns a carrying system comprising an ergonomic back plate (2) which is substantially covering the entire back of a user, a first carrying strap (3) adapted to extend from a first position (P1) of an upper section of said back plate (2) over a first shoulder of a user substantially diagonally downwards towards solar plexus of said user, a second carrying strap (4) adapted to extend from a second position (P2) of said upper section of said back plate over a second shoulder of said user substantially diagonally downwards towards solar plexus of said user, a third carrying strap (5) adapted to extend from a first position (P3) of a lower section of said back plate (2) under a first arm of said user substantially diagonally upwards towards solar plexus of said user, and a fourth carrying strap (6) adapted to extend from a second position (P4) of said lower section of said back plate (2) under a second arm of said user substantially diagonally upwards towards solar plexus of said user. The carrying system is characterized in that at least one of said carrying straps (3, 4, 5, 6) are provided with a connecting body (7) which is fixated at its free end, and each and one of the remaining carrying straps (3, 4, 5, 6) are provided with a fastening body (8) which is fixated at its free end, wherein said at least one connecting body (7) is adapted to connect said respective fastening body (8).
