Baby Stroller Suspension Unit with Height Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional baby strollers lack adjustable height and a proper suspension unit, making it difficult for users of different heights to comfortably place or remove a baby, and they do not absorb shocks or vibrations, which can scare or injure the baby during uneven terrain use.
Innovation Solution
A baby stroller with a suspension unit connected to a base, featuring a movable rod and support frame that adjusts height and includes a pneumatic or hydraulic cylinder for shock absorption, and a mechanism to pivot the seat or bed for orientation changes, allowing users to easily access the baby and maintain comfort and safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the seat or bed is fixed at a certain height in conventional baby strollers, then the structure is simple, but users of different heights cannot conveniently place or remove the baby
Solution Approach 1:
The patent applies the dynamics principle by replacing the fixed-height seat with a height-adjustable suspension system. The seat can be positioned at multiple heights through a telescopic mechanism with lockable positions, allowing users to adjust the seat height according to their own height and terrain conditions. This dynamic adjustment capability resolves the contradiction by enabling convenient baby placement for users of different heights while maintaining structural integrity through the lockable positions.
Solution Approach 2:
The patent employs a pneumatic suspension unit connected to the seat, which uses air pressure to provide shock absorption and height adjustment. The pneumatic system allows the seat to float at different heights and absorb impacts from uneven terrain, resolving the contradiction between ease of operation and device complexity by using gas-based cushioning and positioning mechanisms.
2Object-affected harmful factors
If conventional baby strollers lack a proper suspension unit, then the structure is simple, but shocks and vibrations are directly transferred to the baby causing fear or injury
Solution Approach 1:
The patent implements beforehand cushioning by incorporating a suspension unit with shock-absorbing elements before the baby is exposed to shocks from uneven terrain. The suspension system pre-positioned beneath the seat absorbs impacts, vibrations, and shocks before they can reach the baby, thereby resolving the contradiction between protecting the baby and adding system complexity.
Solution Approach 2:
The patent uses a pneumatic suspension unit that employs compressed air to cushion and absorb shocks and vibrations. The air-filled suspension elements compress and expand to dampen impacts from the ground, providing effective shock protection for the baby while maintaining a relatively simple overall structure compared to complex mechanical suspension systems.
3Adaptability or versatility
If the seat or bed cannot be rotated in conventional baby strollers, then the structure is simple, but the baby cannot see the parent in some situations
Solution Approach 1:
The patent applies dynamics by making the seat rotatable through a pivot mechanism that allows the seat to rotate between facing forward and facing backward orientations. This dynamic repositioning capability enables the baby to face the parent when needed while maintaining structural simplicity through a straightforward rotational joint design.

AI summary
A baby stroller (1) includes a base (11) and a suspension unit (2) is connected to the base (11). The suspension unit (2) has a movable rod (3) which is movably connected to the suspension unit (2). A support frame (12) is connected to the distal end of the movable rod (3) and a seat (14) or a bed (14) is connected to the support frame (12). The suspension unit (2) absorbs shocks and vibration transferred from the road. The distance between the seat (14) or the bed (14) and the base (11) is adjusted by the movement of the movable rod (3). The seat (14) or the bed (14) can be rotated to face the user or to face front.
