Wearable Load Redistribution System for Military Gear
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional protective gear worn by military personnel is heavy, causing exhaustion and limiting range of motion due to the weight distribution on the shoulders.
Innovation Solution
A wearable load redistribution system comprising a base support structure, thoracic frame, and struts that redistribute the weight from the shoulders to the hips, allowing for a wide range of motion and alleviating shoulder burden.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional protective gear is worn to protect the body, then protection is provided, but the weight on the shoulders increases causing exhaustion
Solution Approach 1:
The protective gear is segmented into modular components including a front plate, back plate, and multiple struts that can be independently configured. The weight distribution is segmented across multiple contact points (shoulders, hips, lower back) rather than concentrated on shoulders alone, reducing local burden while maintaining overall protection.
Solution Approach 2:
The load bearing system transitions from a traditional shoulder-only support (1D vertical load) to a three-dimensional weight distribution network involving struts extending from shoulders to hips and lower back. This spatial redistribution across multiple dimensions alleviates shoulder strain by dispersing weight vectors in different directions.
2Reliability
If heavy protective gear is worn, then protection is provided, but range of motion is limited
Solution Approach 1:
The protective gear incorporates dynamic elements including articulation joints at the struts and adjustable coupling structures that allow the armor to move with the wearer. The struts can pivot and adjust their angles to accommodate various body positions and movements, maintaining protection while enabling full range of motion.
Solution Approach 2:
The system allows adjustment of structural parameters such as strut angles, joint positions, and coupling configurations to optimize both protection and mobility for different operational requirements. The articulation parameters can be modified to balance protective coverage with movement freedom based on mission needs.
3Ease of operation
If weight is distributed to hips and lower back, then shoulder burden is reduced, but structural complexity increases
Solution Approach 1:
The struts serve multiple functions simultaneously: they provide structural support for weight bearing, act as articulation joints for movement, and function as coupling elements connecting the front and back plates. This multi-functionality reduces the need for separate components, managing structural complexity while achieving weight distribution goals.
Solution Approach 2:
The coupling structures act as intermediaries between the struts and the front/back plates, providing standardized connection points that simplify the overall assembly. These coupling elements mediate the complex interactions between multiple struts and plates, making the system more manageable despite its distributed weight-bearing capability.

AI summary
A wearable load redistribution system can include a base support structure and a thoracic frame configured to surround an upper torso of a wearer of the system. The base support structure can include a support frame and a plurality of support members disposed at distal ends of the support frame. The thoracic frame can include a coupling structure, a front plate, and a plurality of struts. A connector member can removably connect the coupling structure to the support frame. The plurality of struts is mated to the front plate to redistribute a weight of the front plate away from shoulders of the wearer and towards the base support structure.
