Carry Harness with Adjustable Posts for Hands-Free Ballistic Shields
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing ballistic shields for law enforcement lack an effective body-carried carrier system that is easily adjustable for different-sized wearers and does not provide a guide and aiming arrangement for a shouldered weapon.
Innovation Solution
A body-supported harness system with adjustable upright posts and straps that allow for secure carrying of heavy objects like ballistic shields, incorporating a waist belt, shoulder harness, and oblique object support straps, enabling hands-free operation and accommodating various user sizes and weapon guidance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a body-carried carrier system is designed to support front loads like ballistic shields, then the load-bearing capability is improved, but the adjustability for different-sized wearers deteriorates
Solution Approach 1:
The carrier system is divided into separate adjustable components including shoulder harness straps, waist belt, and upright posts that can be independently adjusted to accommodate different body sizes while maintaining load-bearing capability
Solution Approach 2:
The system incorporates dynamic adjustment mechanisms allowing users to modify strap lengths, belt circumference, and post heights to adapt the rigid load-bearing structure to various user sizes and configurations
2Stability of the object's composition
If upright posts are made fixed and non-adjustable, then the structural stability is improved, but the adaptability to different user heights deteriorates
Solution Approach 1:
The upright posts incorporate adjustable height mechanisms that allow users to modify post length while maintaining structural integrity and stability during use, adapting to different user heights and equipment configurations
3Strength
If the carrier system is designed for heavy load support, then the weight capacity is improved, but the ease of quick deployment deteriorates
Solution Approach 1:
The system uses modular components with standardized connection points and quick-release mechanisms that allow heavy loads to be rapidly attached and detached without compromising the load-bearing structure
Solution Approach 2:
Straps and connection points are pre-positioned and pre-tensioned to enable rapid deployment of heavy equipment without requiring complex assembly or adjustment during critical moments

AI summary
A carry harness system includes a support belt arranged to encircle a user's waist; a shoulder harness arranged to lay over the user's shoulders on opposite sides of the user's head; two front belt support straps arranged to be on a front side of the user and extending between the shoulder harness and the support belt; two rear belt support straps arranged to be on a rear side of the user and extending between the shoulder harness and the support belt; two post receivers supported on the support belt on the rear side; and two posts. The posts are arranged spaced-apart on the rear side, fit into the receivers and extending vertically between the post receivers and a vertical elevation above the shoulder harness. The two posts are fixed to the shoulder harness and have strap connections at tops of the posts. Two object support straps extend between the strap connections forwardly and obliquely to attachments on a rear side of the object to be carried.
