Compound Arc Backpack Frame Load Distribution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing backpack designs, known as 'patrol nicks,' fail to adequately support, protect, and stabilize the modern battlefield gear, leading to discomfort and balance issues due to sagging and sloshing loads, especially when combined with body armor.
Innovation Solution
A backpack frame with a compound arc design featuring mirrored, longitudinally concave and twisted vertical support members that distribute load through a central axis, allowing independent flexion to accommodate torso movement and incorporating receiving pockets for load stabilization, made from materials like injection molded thermoplastics or carbon-fiber composites.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional patrol nick backpacks are used to carry modern battlefield gear, then the backpack can be worn with simple structure, but the load sags and sloshes causing discomfort and balance issues
Solution Approach 1:
The backpack is divided into multiple functional sections including upper and lower load-bearing compartments, side pockets, and integrated frame structures. This segmentation allows different parts of the load to be distributed and stabilized independently, preventing sagging and sloshing while maintaining overall load stability.
Solution Approach 2:
The patent employs adjustable straps, removable panels, and configurable compartments that allow the backpack's structural parameters to be changed based on load requirements. This enables optimization of load distribution and stability for different mission requirements while maintaining comfort.
2Volume of moving object
If heavy and dense equipment is carried in small volume backpacks, then the backpack volume is minimized, but the load concentrates pressure uncomfortably
Solution Approach 1:
The patent utilizes three-dimensional load distribution through vertically stacked compartments and laterally distributed side pockets. This multi-dimensional arrangement spreads the concentrated pressure of heavy equipment across larger surface areas of the wearer's back and shoulders, reducing discomfort while maintaining compact volume.
Solution Approach 2:
The backpack employs composite construction combining rigid frame materials with flexible cushioning materials and breathable fabrics. This composite structure provides both structural support for load-bearing and comfort features that distribute pressure evenly across contact surfaces.
3Object-affected harmful factors
If body armor is worn with patrol nick backpacks, then the armor provides protection, but it imparts little to no stabilizing influence on the backpack
Solution Approach 1:
The patent integrates the backpack frame with body armor through attachment points, shared structural elements, and coordinated positioning systems. This merging allows the rigid armor to work in conjunction with the backpack frame to provide combined stabilization, transforming the armor from a separate protective element into an integrated stabilizing component.

AI summary
A novel backpack frame and backpack are described where the frame has a common point from which a pair of upper vertical support members ascend and a pair of lower vertical support members descend. The lower vertical support members are mirror images of each other and one lower vertical support member has a twist in a first direction to form a latitudinal concavity relative to the back side of the backpack and another lower vertical support member has another twist in a second direction to form another longitudinal concavity relative to the backpack back side, where the second direction is opposite to the first direction.
