Adjustable Backpack Straps and Hip Belt for Load Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing backpacks often fail to accommodate the diverse anatomies of individuals, leading to discomfort and instability in load distribution, particularly when carrying substantial loads over long distances.
Innovation Solution
The backpacks feature adjustable shoulder straps and hip belts that can be customized to fit different shoulder and hip anatomies, with mechanisms like hook and loop fasteners, snap fasteners, and buckles allowing for adjustable lengths and angles to ensure proper positioning and load distribution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If fixed-length shoulder straps and hip belts are used, then the backpack structure is simple, but it cannot accommodate diverse human anatomies leading to discomfort and poor load distribution
Solution Approach 1:
The patent applies dynamics by making the shoulder straps and hip belts adjustable in length and configuration. The shoulder straps can be extended or retracted to different lengths, and the hip belts can be adjusted to different angles and positions, allowing the backpack to adapt to various human anatomies rather than being fixed in a single configuration
Solution Approach 2:
The patent segments the backpack into adjustable components - the shoulder straps are separated into adjustable segments that can be independently configured, and the hip belts are divided into adjustable sections that can be positioned at different angles. This segmentation allows each part to be customized for different body types while maintaining overall structural integrity
2Ease of operation
If adjustable mechanisms are added to accommodate different anatomies, then comfort and load distribution improve, but the device complexity increases
Solution Approach 1:
The patent changes key parameters of the backpack - the length of shoulder straps, the angle and position of hip belts, and the configuration of connecting elements. By allowing these parameters to be adjusted, the backpack can be optimized for comfort and load distribution across different users without requiring a complete redesign for each anatomy
3Stability of the object's composition
If multiple adjustment mechanisms are provided for customizing fit, then load stability improves, but the ease of operation decreases due to more adjustment components
Solution Approach 1:
The patent merges multiple adjustment functions into integrated mechanisms. The shoulder strap adjustment is combined with the connection to the backpack body, and the hip belt adjustment is integrated with the attachment points on the frame. This merging allows users to make adjustments through unified actions rather than manipulating separate, independent mechanisms for each adjustment

AI summary
A backpack may include a pack portion having a backside having a first slot and a frame having a second slot, wherein a flexible end portion of the shoulder strap passes through the first slot in the second slot and is adjustably connected to the frame to adjust a length of the flexible end portion of the shoulder strap that extends beyond the first slot. A backpack may include a hip belt having a rear portion connected to a frame, wherein the rear portion has left and right end portions that are repositionable at different angles relative to one another.
