Stroller Seat Fixing Base Sliding Mechanism for Height Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional foldable strollers have a higher overall height when the seat is folded, making them less convenient for storage and transportation.
Innovation Solution
A stroller design featuring a frame, a sliding member, and a seat fixing base, where the sliding member is rotatably connected to the frame and the seat fixing base is both rotatably and slidably connected to the sliding member, allowing the seat fixing base to slide when the frame is folded, thereby reducing the overall height.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the seat is folded along with the frame, then the folding operation is simple, but the overall height of the frame increases
Solution Approach 1:
The seat fixing base is designed to slide relative to the sliding member during frame folding, dynamically adjusting the seat position. When the frame folds, the seat fixing base slides to lower the seat, and when the frame unfolds, the seat returns to its original position, achieving adaptive height adjustment without complex mechanisms
Solution Approach 2:
The seat fixing base and sliding member form a nested structure where the seat fixing base can slide within the sliding member. This nested arrangement allows the seat to be positioned lower during folding by sliding into a retracted position, reducing the overall height while maintaining a compact structure

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The design effectively reduces the overall height of the stroller when folded, enhancing storage and transportation convenience.
Implementation Method 1
The sliding member is rotatably connected to the frame
Implementation Method 2
the seat fixing base is rotatably connected to the frame and slidably connected to the sliding member

AI summary
A stroller includes a frame, a sliding member and a seat fixing base. The sliding member is rotatably connected to the frame. The seat fixing base is rotatably connected to the frame and slidably connected to the sliding member. When the frame is folded, the frame drives the seat fixing base to slide with respect to the sliding member.
