Adaptive Waist Belt Angular Adjustment Backpack Weight Distribution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional waist belts in backpacks are difficult to adjust, leading to uneven weight distribution on the hips, causing discomfort due to complex and time-consuming adjustment procedures, often resulting in the weight being applied to small areas of the hipbone rather than being distributed uniformly along the waistline.
Innovation Solution
A waist belt design featuring two side hip portions with a webbing system that forms a closed loop, allowing for angular adjustment by sliding through a uniloop buckle and strap connection, enabling the belt to accommodate various waist shapes without intricate setting, with the webbing's length being adjustable to fit different torso profiles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional waist belts with multiple adjustable straps and buckles are used to fit different waist shapes, then adaptability to different users is improved, but device complexity and ease of operation deteriorate due to difficult and time-consuming adjustments
Solution Approach 1:
The waist belt incorporates a dynamic adjustment mechanism where the hip belt can rotate angularly relative to the pack body through a pivot joint. This allows the belt to automatically adapt to different waist shapes and sizes without requiring complex manual adjustments of multiple straps and buckles, resolving the contradiction between adaptability and device complexity
Solution Approach 2:
The invention changes the angular parameter of the hip belt relative to the pack body through a single buckle adjustment. By modifying just one angular parameter instead of multiple length and position parameters, the system achieves adaptability to different waist shapes while significantly reducing the complexity of the adjustment mechanism
2Adaptability or versatility
If conventional waist belts with multiple adjustment points are used to achieve proper angular position, then adaptability is improved, but ease of operation deteriorates due to difficult access to adjustment elements
Solution Approach 1:
The invention merges multiple adjustment functions into a single buckle mechanism. The buckle simultaneously controls both the length adjustment and the angular position of the hip belt, eliminating the need for separate adjustment points that are difficult to access. This consolidation dramatically improves ease of operation while maintaining full adaptability
Solution Approach 2:
The invention extracts the complex system of multiple adjustable straps and buckles from the conventional design, replacing it with a simplified single-buckle mechanism that provides the same adaptability. This extraction removes the operational difficulties associated with accessing and adjusting multiple separate elements
3Reliability
If waist belt is tightly bound around the torso to ensure stability, then reliability is improved, but comfort deteriorates when weight is applied to small hipbone areas instead of uniformly along the waistline
Solution Approach 1:
The dynamic angular adjustment of the hip belt allows it to automatically align with the user's waist shape, ensuring that the weight is distributed uniformly along the entire waistline rather than concentrated on small hipbone areas. This maintains both the stability needed for reliable backpack carrying and the comfort required to prevent discomfort
Solution Approach 2:
By adjusting the angular parameter of the hip belt through the buckle mechanism, the system optimizes the contact area between the belt and the user's waist. This parameter change ensures uniform weight distribution along the waistline, simultaneously achieving reliability through tight binding and comfort through proper weight distribution
