Backpack Compression System Using Strap Routing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional backpacks cause discomfort and potential back injuries due to sagging, which leads to improper spine alignment and increased fatigue when carrying heavy loads, as they do not effectively address the sagging and back support issues simultaneously.
Innovation Solution
A simple compression system for backpacks where each shoulder strap is connected at the top side and body side, extending along the lateral side, threaded through D-rings, and terminating at the backpack body, allowing the backpack to be automatically compressed closer to the user's back when the straps are tied, with an optional back support device providing additional comfort and support.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Weight of moving object
If conventional backpacks are used to carry heavy loads, then the backpack can transport the required weight, but the backpack sags and causes improper spine alignment leading to discomfort and potential back injuries
Solution Approach 1:
The patent changes the structural parameters of the backpack by adding a compression system with straps and buckles that can be adjusted to different tension levels. This allows the backpack to maintain its shape and position under various load conditions, preventing sagging and maintaining proper spine alignment while carrying heavy loads.
Solution Approach 2:
The compression system introduces dynamic adjustability to the backpack structure. The straps can be tightened or loosened depending on the load weight, and the buckles allow for easy adjustment. This dynamic adaptation enables the backpack to maintain optimal ergonomic positioning across different carrying scenarios.
2Object-affected harmful factors
If compression systems with straps are added to reduce sagging, then back support is improved, but the device complexity and manufacturing cost increase
Solution Approach 1:
The compression system is divided into separate modular components: straps attached to the backpack body, D-rings for routing, and buckles for adjustment. This segmentation allows each component to perform its specific function independently and simplifies manufacturing and assembly. The modular design also enables easy adjustment and maintenance.
Solution Approach 2:
Instead of adding complex mechanical structures to prevent sagging, the patent uses a simple inversion approach: flexible straps that can be routed through D-rings and secured with basic buckles. This inverted approach uses soft, flexible elements rather than rigid mechanical structures, achieving compression and support with minimal complexity.
3Object-affected harmful factors
If extended straps are used to lift and compress the backpack, then compression is achieved, but the user has to further pull down the straps completing the process
Solution Approach 1:
The compression system is designed to be self-adjusting through the interaction of its components. When the buckles are tightened, the straps automatically route through the D-rings and apply compression force. The system self-regulates the compression level based on the buckle tension, eliminating the need for additional manual adjustment steps by the user.

AI summary
A compression system for an ergonomic backpack is disclosed. The backpack includes a backpack body having a top side, a bottom side, two lateral sides, a body side, an outer side and a pair of shoulder straps. In the embodiment, each shoulder strap is connected at a junction of the top side and the body side, extended along the corresponding lateral side, threaded through the D-ring with a distal end connected to the backpack body at a junction of the outer side and the lateral side. The invention also comprises an optional back panel and an optional back support device, secured to the body side. The back panel and support device may be filled with padding material such as a gel, foam, rubber, fluid or the like. When the user ties the two straps, the backpack is automatically compressed and moves closer to the user's back The system, operated like a regular two-strap backpack, allows the user to carry heavier loads for a longer period of time with less fatigue.
