Wearable Carrying System With Pneumatic Bladder Straps
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional backpack and bag strap systems fail to provide effective comfort and reduce stress and injury when carrying heavy loads, as they do not adequately adjust to the user's specific needs, terrain, and physical condition.
Innovation Solution
A wearable carrying system with AI-controlled straps and bladders that use sensors to analyze real-time data on the user's environment, physical condition, and terrain, adjusting the load distribution to optimize comfort and reduce strain through mechanical, pneumatic, and hydraulic mechanisms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional strap systems are used with fixed positioning, then the device complexity is low, but the comfort and stress reduction for heavy loads deteriorates
Solution Approach 1:
The strap system transitions from fixed positioning to dynamic, adjustable positioning through mechanical mechanisms that allow real-time modification of strap location and tension. This enables the system to adapt to different user needs, load weights, and terrain conditions, thereby improving comfort without requiring complete system redesign for each scenario.
Solution Approach 2:
The system changes critical parameters such as strap position, tension level, and distribution pattern through adjustable mechanisms. By modifying these parameters dynamically rather than being fixed, the system can optimize comfort and stress distribution for various carrying conditions while maintaining a relatively simple base design.
2Ease of operation
If additional foam and material padding are added to straps, then the comfort for users is improved, but the stress reduction and injury prevention deteriorates
Solution Approach 1:
The system replaces passive mechanical cushioning (foam and material padding) with an active mechanical adjustment system that can dynamically change strap position and tension. This active mechanical system directly addresses stress distribution and load placement, providing both comfort and stress reduction simultaneously rather than relying solely on passive cushioning materials.
3Ease of operation
If more adjustability is provided to the strap by shaping it to fit the human shoulder and torso, then the comfort is improved, but the effectiveness in reducing stress for heavy loads deteriorates
Solution Approach 1:
The strap system incorporates dynamic adjustment mechanisms that allow the strap position, angle, and tension to be modified in real-time. This dynamic capability enables the system to optimize both comfort through proper fit and stress reduction through adjustable load distribution, addressing both requirements simultaneously rather than compromising one for the other.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system increases user load capacity by up to 35% and provides continuous comfort by automatically adjusting the load to an optimal position, reducing fatigue and stress, and can be manually or semi-automatically controlled.
Implementation Method 1
a bladder system fixed to one side of the strap, or in a sleeve surrounding the strap, with the bladders being sequentially inflated and compressed by controlling the introduction and removal of a fluid into and from the bladders
Implementation Method 2
Force sensors are located on the straps and shoulder pad to generate signals relating to a force exerted on the shoulder or the torso of a user of the wearable carrying system

AI summary
A wearable carrying system for a container such as a backpack or a bag has one or two straps that extend over the shoulder(s) and torso of a user. The strap or straps include a bladder system that is sequentially inflated or deflated by the controllable introduction and removal of a fluid into and out of the bladder system. A shoulder pad is located on a portion of the strap, the shoulder pad having an additional controllable bladder system to adjust the load bearing position of a strap on the shoulder of a user.
