Adjustable Carrying Pack Strap Configuration for Snag Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing adjustable backpacks for outdoor sports equipment, such as skis and snowboards, have complex designs with numerous exposed straps that can snag or catch, leading to potential damage or injury when not in use.
Innovation Solution
The design features adjustable straps with loops and passages that allow for quick configuration changes between carrying skis and snowboards, with the option to store straps in pockets when not in use, reducing exposure and preventing snagging.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If adjustable straps are added to carry different equipment, then adaptability is improved, but device complexity increases and straps clutter the outside of the pack
Solution Approach 1:
The patent implements a universal strap system where a single strap can serve multiple functions by attaching to different loops on the pack. The strap can be configured to carry skis, snowboards, or other equipment by simply changing which loops it connects to, eliminating the need for separate dedicated straps for each equipment type.
Solution Approach 2:
The strap system is designed to be dynamically reconfigurable. Users can quickly adjust the strap configuration by detaching and reattaching to different loops, allowing the pack to adapt to different carrying needs without requiring complex mechanical adjustment mechanisms or multiple fixed straps.
2Adaptability or versatility
If adjustable straps are added to carry different equipment, then adaptability is improved, but ease of operation deteriorates due to inability to adjust quickly
Solution Approach 1:
The strap system is segmented into modular components with attachment points at various locations along the strap and multiple loops on the pack. This segmentation allows users to quickly reconfigure the system by simply disconnecting and reconnecting segments rather than adjusting entire strap lengths or dealing with complex mechanisms.
Solution Approach 2:
Multiple loops are pre-positioned at strategic locations on the pack body, allowing users to quickly attach straps to the optimal configuration for different equipment types without requiring measurement, calculation, or complex adjustment during the carrying process.
3Ease of operation
If straps are exposed on the outside of the pack, then adjustability is maintained, but harmful factors increase due to snagging and catching
Solution Approach 1:
The patent extracts the adjustment mechanism from the external strap system and integrates it into the pack body through internal loops and attachment points. The straps remain externally accessible for adjustment but can be routed through or stored within the pack structure when not in use, removing them from the external environment where they could snag on branches or equipment.
Solution Approach 2:
The strap system can be nested within the pack structure when not in use. Straps can be routed through internal channels or stored in dedicated compartments within the pack body, allowing the external surface of the pack to remain smooth and free of protruding straps that could cause snagging, while maintaining full adjustability functionality.

AI summary
An adjustable carrying pack includes a main body having an outer surface with an upper portion, a lower portion, and a rear portion. A first strap having a plurality of loops is disposed along a first side of the outer surface of the main body and a second strap having a plurality of loops is disposed along a second side of the outer surface of the main body. A bottom strap includes a fixed end and a free end having an attachment element. In a first configuration, the attachment element of the bottom strap is attached to a loop of the first strap. In a second configuration, the attachment element of the bottom strap is attached to a loop of the second strap.
