Stroller Seat Damping Bracket with Nested Elastic Element
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing strollers lack an effective damping structure on their seats, leading to discomfort for children when riding over bumpy roads, and the existing elastic wire solutions provide insufficient strength and damping.
Innovation Solution
A damping device is integrated into the stroller, comprising a bracket structure with a damping pipe and sleeve, and a damping elastic element, which delays the downward movement of the seat part, enhancing the damping effect.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a damping structure is added to the stroller seat, then the damping effect is improved, but the device complexity increases
Solution Approach 1:
The damping sleeve is nested within the damping pipe, forming a compact bracket structure. The damping elastic element is integrated into this nested arrangement, allowing multiple functional components to occupy overlapping or adjacent spaces. This nesting approach achieves effective damping while minimizing the overall space required, thus improving damping performance without proportionally increasing device complexity.
Solution Approach 2:
The bracket structure is designed to be dynamically responsive to road conditions. The damping elastic element provides elastic resistance that varies with the rate of compression, and the pivot connections allow the structure to adapt its motion characteristics. This dynamic behavior enables the damping device to automatically adjust to different bump sizes and frequencies, improving damping effectiveness without requiring complex control systems.
2Reliability
If elastic wires are used for damping, then some damping effect is achieved, but the seat plate strength and bearing capacity are insufficient
Solution Approach 1:
The damping function is segmented from the seat plate structure. Instead of relying on the seat plate itself to provide damping, a separate bracket structure with damping pipe, damping sleeve, and damping elastic element is introduced. This segmentation allows the seat plate to focus on providing structural support and bearing capacity, while the dedicated damping structure handles the damping function, resolving the conflict between damping effect and structural strength.
Solution Approach 2:
The bracket structure acts as an intermediary between the seat plate and the damping elastic element. It transfers and distributes the damping forces generated by the elastic element throughout the seat assembly, preventing concentrated loads that would compromise seat plate strength. The pivot connections and sliding mechanisms in the bracket structure serve as force distribution pathways, protecting the seat plate from excessive stresses while maintaining effective damping.

AI summary
A damping device is arranged on a first pipe (101) and a second pipe (102) of a seat pipe (100) of the stroller, which are parallel to each other, and carries a seat part of the stroller. The damping device comprises a bracket structure (10, 20) pivotally connected to the first pipe and the second pipe. The bracket structure is arranged to elastically prevent the bracket structure from pivoting relative to the first pipe and the second pipe by means of a damping elastic element to delay a downward movement of the seat part. The damping device of the stroller enables the stroller to achieve better damping effect.
