Backpack Frame Pivot Mechanism for Hip Weight Distribution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional backpacks often lead to discomfort and potential pain during walking or hiking due to the constant shifting of weight from the pack portion to the belt portion, which can cause uneven distribution of weight around the hips.
Innovation Solution
The backpack incorporates a belt portion with a frame pocket that allows the belt portion to pivot relative to the pack portion and frame, ensuring a more even distribution of weight by accommodating the natural movement of the hips.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the belt portion is rigidly coupled to the pack portion and frame, then structural stability is improved, but weight distribution becomes uneven causing discomfort during walking or hiking
Solution Approach 1:
The patent applies the dynamics principle by introducing a pivot connection between the belt portion and the frame, allowing the belt portion to rotate relative to the frame. This dynamic connection enables the belt to adapt to the natural movement of the user's hips during walking or hiking, maintaining even weight distribution while preserving structural stability through the frame's support.
2Ease of operation
If the belt portion is made flexible to accommodate hip movement, then comfort during walking is improved, but weight transfer from pack to belt becomes ineffective
Solution Approach 1:
The patent applies composite materials by combining a rigid frame structure with a flexible belt portion through a pivot connection. The frame provides structural stability and effective weight transfer from the pack, while the flexible belt portion accommodates hip movement during walking. This composite construction resolves the contradiction between flexibility for comfort and rigidity for weight transfer efficiency.
3Ease of operation
If a pivot connection is introduced between belt and frame, then weight distribution evenness is improved, but device complexity increases
Solution Approach 1:
The patent applies segmentation by dividing the backpack into distinct functional components: a rigid frame structure for stability and weight transfer, and a separate belt portion for comfort and weight distribution. The pivot connection serves as a simple rotational joint that links these segments, allowing independent optimization of each component's function while maintaining overall system integrity.

AI summary
A backpack includes a pack portion adapted to receive and store contents, two shoulder straps connected to the pack portion, a belt portion adapted to be worn around a waist of a user, and a frame. The belt portion includes a frame pocket. The frame includes an upper portion and a lower portion, wherein the upper portion is coupled to the pack portion and the lower portion is disposed in the frame pocket such that the frame can transfer weight from the pack portion to the belt portion. The frame pocket is adapted to pivot relative to the lower portion of the frame such that the belt portion can pivot relative to the frame and the pack portion.
