Hipbelt Suspension System with Movable Coupling Element
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing backpacks with hipbelts often lack adjustability, leading to discomfort and stress on the hips and lower back due to inadequate accommodation of pelvic and hip movement during outdoor activities on uneven terrain.
Innovation Solution
A backpack assembly featuring a hipbelt suspension system with a back panel support and a hipbelt coupling element that moves between stops, allowing for translational movement and pivotal adjustment, ensuring comfortable wear and distribution of load.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed hipbelt is used in traditional backpacks, then the structure is simple and stable, but the hipbelt cannot accommodate pelvic and hip movement during walking or hiking on uneven terrain, causing discomfort and stress on the user's hips and lower back
Solution Approach 1:
The hipbelt coupling element is designed to move dynamically between first and second positions along the back panel support, allowing the hipbelt to adapt to pelvic and hip movement during walking or hiking. This dynamic adjustment capability resolves the contradiction by enabling the hipbelt to accommodate user motion while maintaining a relatively simple mechanical structure through guided movement along the support.
Solution Approach 2:
The hipbelt suspension system is divided into distinct components: the back panel support, the movable coupling element, and the hipbelt attachment mechanism. This segmentation allows each component to perform its specific function independently, providing adjustability through the movable coupling element while keeping the overall structure organized and manageable, thus addressing both adaptability and complexity concerns.
2Ease of operation
If a movable hipbelt coupling element is introduced to accommodate hip movement, then user comfort and freedom of movement are improved, but the structural complexity of the backpack increases
Solution Approach 1:
The coupling element is designed to move freely between first and second positions along the back panel support, enabling the hipbelt to adapt to pelvic and hip movement during walking or hiking. This dynamic adjustment capability resolves the contradiction by enabling the hipbelt to accommodate user motion while maintaining a relatively simple mechanical structure through guided movement along the support.
3Object-affected harmful factors
If the hipbelt is made adjustable to reduce stress on hips and lower back, then user comfort is improved, but the stability of the backpack may be reduced
Solution Approach 1:
The hipbelt coupling element moves dynamically between first and second positions along the back panel support, allowing the hipbelt to adapt to pelvic and hip movement during walking or hiking. This dynamic adjustment capability resolves the contradiction by enabling the hipbelt to accommodate user motion while maintaining a relatively simple mechanical structure through guided movement along the support.
Solution Approach 2:
The system changes the positional parameter of the hipbelt relative to the back panel by allowing the coupling element to move between first and second positions. This parameter change enables the hipbelt to maintain optimal contact and support on the user's hips during various movements, reducing stress while preserving stability through controlled adjustment ranges.

AI summary
A hipbelt suspension system for use with a backpack having a back panel includes a back panel, a generally planar hipbelt coupling element, a hipbelt support plate and a hipbelt. The back panel support is coupled a lower region of the back panel. The back panel support includes an engagement region having opposing first and second stops. The hipbelt coupling element movably engages the engagement region of the back panel support to enable translational movement of the hipbelt coupling element between the first and second stops of the engagement region of the back panel. A hipbelt attachment mechanism pivotally coupled to the hipbelt coupling element about a first axis. A hipbelt is secured to the hipbelt attachment mechanism.
