Vest Pack Weight Redistribution for Backpack Compatibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional auxiliary packs inadequately distribute weight and are difficult to access, and they are not compatible with backpacks, especially when filled.
Innovation Solution
A vest pack design that allows for weight redistribution by being worn under a backpack, featuring right and left pocket regions positioned below the breasts, connected by a zipper from sternum to belt line, with suspenders and elastic straps for secure fit, enabling easy access and compatibility with existing backpacks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If conventional auxiliary packs are designed to carry items, then weight capacity is provided, but weight distribution is poor and accessibility is difficult
Solution Approach 1:
The pack is divided into multiple compartments including a main compartment, a chest pocket, and a waist pocket. This segmentation allows items to be distributed across different regions, improving both weight distribution and accessibility by enabling users to access specific compartments without exposing the entire pack contents.
Solution Approach 2:
The pack transitions from a single-location carrying design to a multi-dimensional distribution system with components positioned on the chest, waist, and back. This spatial distribution across multiple dimensions improves weight distribution while maintaining accessibility through strategically placed compartments.
2Ease of operation
If conventional packs are designed to be worn, then carrying function is provided, but compatibility with backpacks is poor
Solution Approach 1:
The pack is designed with a compressible main compartment that can be nested within or attached to a backpack. The chest pocket and waist pocket can be independently worn with or without a backpack, providing versatility and compatibility while maintaining the carrying function.
Solution Approach 2:
The pack is designed to serve multiple functions: it can be worn as a standalone vest pack, attached to a backpack, or used with the backpack removed. This multi-functionality ensures compatibility with various backpack configurations while maintaining its primary carrying function.
3Device complexity
If weight is concentrated on the back, then backpack structure is simple, but weight distribution is poor
Solution Approach 1:
The load-carrying function is segmented across multiple locations: the main compartment on the back, the chest pocket on the front, and the waist pocket at the lower back. This segmentation distributes weight across different body regions, improving weight distribution without significantly increasing overall structure complexity.
Solution Approach 2:
Different portions of the pack are optimized for local functions: the main compartment provides bulk storage on the back, the chest pocket offers accessible storage on the front, and the waist pocket provides additional capacity at the lower back. This local optimization improves overall weight distribution while maintaining structural simplicity.
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 vest pack effectively redistributes weight from the back to the chest region, enhancing load capacity and ease of access while being compatible with backpacks, improving user convenience and comfort.
Implementation Method 1
a back region comprising at least one elastic strap connecting opposing back sides of the right and left pocket regions

AI summary
A vest pack includes right and left pocket regions. Each pocket region is adapted for being positioned just below the respective right and left breast of a wearer. The vest pack further includes a zipper that connects the right and left pocket regions from approximately the sternum of the wearer to approximately a belt line of the wearer, and a pair of suspenders having a strap connected proximate each second pocket and adapted to be worn over the shoulders of the wearer. The vest pack further includes a back region comprising at least one elastic strap connecting opposing back sides of the right and left pocket regions, and to the straps of the pair of suspenders.
