Adjustable Backpack Straps and Hip Belt for Ergonomic Load Fit
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing backpacks struggle to provide a comfortable and ergonomic fit for individuals with varying anatomies, leading to discomfort and inefficient load distribution.
Innovation Solution
The backpack features adjustable shoulder straps and hip belts that can be customized to fit different shoulder and hip sizes through the use of hook and loop fasteners, snap fasteners, and buckles, allowing for adjustable lengths and angles to accommodate individual anatomies.
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 individuals with varying anatomies leading to discomfort and inefficient load distribution
Solution Approach 1:
The shoulder straps and hip belts are designed with adjustable lengths and angles, transforming fixed components into dynamic, adaptable elements. Multiple connection positions and angular adjustments allow the backpack to adapt to different shoulder widths, hip sizes, and anatomical variations, directly resolving the contradiction between simplicity and adaptability
Solution Approach 2:
The invention implements adjustable parameters including strap length, connection position, and angular orientation. These parameter changes enable the backpack to accommodate various anatomical dimensions while maintaining structural integrity, achieving versatility without requiring completely different backpack designs
2Ease of operation
If adjustable shoulder straps and hip belts are implemented, then comfort and load distribution are improved, but the device complexity increases
Solution Approach 1:
The adjustment mechanism is segmented into modular components: adjustable shoulder straps with multiple connection points, adjustable hip belts with independent angle adjustment, and separate fastening systems. This segmentation allows each component to be optimized independently while maintaining overall simplicity and user comfort
Solution Approach 2:
The adjustment mechanisms serve multiple functions: length adjustment for different body sizes, angle adjustment for ergonomic positioning, and load distribution optimization. This multi-functionality consolidates what could be multiple separate mechanisms into integrated adjustment systems, reducing overall complexity while improving comfort
3Stability of the object's composition
If customizable fit options are provided, then load stability is enhanced, but the number of components and adjustment mechanisms increases
Solution Approach 1:
The adjustable connection points and angular adjustments create a dynamic system that can be customized for optimal load stability. The ability to reposition connection points on the frame and adjust strap angles allows users to fine-tune load distribution and stability according to their specific needs, achieving enhanced stability without requiring additional structural components

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.
