Stroller Headrest Pivot Mechanism for Compact Folding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Foldable strollers have a relatively large folded volume, making them less convenient for storage.
Innovation Solution
A headrest-adjusting mechanism that allows the headrest-supporting tube to rotate relative to the backrest-supporting tube from a usable position to a folded position, reducing the stroller's folded volume by abutting the headrest against the rear end of the folded stroller.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the stroller is designed to be foldable, then portability is improved, but the folded volume becomes relatively large
Solution Approach 1:
The headrest-supporting tube is designed to be rotatable relative to the backrest-supporting tube through a pivot mechanism, allowing the headrest to dynamically adjust its position between usable and folded states. This dynamic configuration enables the headrest to be positioned closer to the main body when folded, significantly reducing the overall folded volume of the stroller while maintaining ease of portability.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Significantly reduces the folded volume of the stroller, enhancing storage convenience by allowing the headrest-supporting tube to be easily rotated between usable and folded positions using a pivot mechanism and compression spring.
Implementation Method 1
a compression spring arranged to engage the first pivot member and the second pivot member
Implementation Method 2
a first pivot member connected to the headrest-supporting tube and arranged to pivot relative to a second pivot member connected to the backrest-supporting tube

AI summary
A headrest-adjusting mechanism is adapted for use with a stroller. The stroller includes a headrest-supporting tube and a backrest-supporting tube. The headrest-adjusting mechanism is adapted to be connected between the headrest-supporting tube and the backrest-supporting tube in such a manner to allow for rotation of the headrest-supporting tube relative to the backrest-supporting tube from a usable position to a folded position in a predetermined direction.
