Infant Carrier Seat Height Adjustment With Collapsible Frame
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional infant carrier apparatuses lack height adjustment functionality, limiting their usability and portability due to a fixed size, which restricts their application and makes them less convenient for transport.
Innovation Solution
An infant carrier apparatus with a support frame, swing arm, and seat assembly that includes a height adjustment mechanism, allowing the seat assembly to be adjusted in height and the support frame to be collapsed for reduced size, enhancing portability and flexibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the support frame is made with fixed length, then the structural stability is maintained, but the portability and packaging efficiency deteriorate
Solution Approach 1:
The support frame is divided into multiple segments (first support frame portion and second support frame portion) that can be relatively moved with respect to each other. This segmentation allows the frame to be collapsed into a compact configuration for transport while maintaining full structural stability when deployed for use.
2Ease of operation
If the support frame is collapsed to reduce size, then the portability is improved, but the height adjustment functionality is lost
Solution Approach 1:
The support frame incorporates dynamic adjustment capabilities that allow it to transition between different states: a compact collapsed state for portability and an extended state with adjustable height positions for functionality. The frame can be collapsed after use to reduce its footprint while maintaining the capability for height adjustment during use.
3Device complexity
If the seat assembly height is fixed, then the device complexity is reduced, but the adaptability to different users and environments deteriorates
Solution Approach 1:
The seat assembly height is made dynamically adjustable through the relative movement mechanism between the first and second support frame portions. This allows the height to be adapted to different users and environments while maintaining a relatively simple overall structure that does not require complex additional mechanisms.

AI summary
An infant carrier apparatus includes a support frame having a generally L-shape, a swing arm and a seat assembly. The swing arm includes an upper segment, a lower segment parallel to the upper segment, and an upright segment connected between the upper segment and the lower segment, wherein the upper segment is pivotally connected with an upper end of the support frame. The seat assembly is disposed in a region between the upper segment and the lower segment, and is connected with the lower segment of the swing arm. The infant carrier apparatus can also include an adjustment mechanism that allows to conveniently adjust the height of the seat assembly.
