Nested Head Support Wings in Baby Car Seat Packaging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing baby car seats have a large packaging volume due to the head support bracket and body taking up significant space when disassembled, making them bulky for transportation.
Innovation Solution
The baby car seat design incorporates accommodating holes on the backrest body for the head support wings, allowing the head support to be nested between backrest wings, and a position adjustment mechanism with locking grooves and a locking pin to minimize the height and volume during packaging.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the head support bracket and head support body are detachably connected and stacked during packaging, then the car seat can be disassembled for transport, but the head support components take up a big space resulting in large packaging volume
Solution Approach 1:
The head support wings are designed to be inserted into and nested within the backrest wings during packaging. The accommodating holes in the backrest body receive the head support wings, creating a compact nested configuration that significantly reduces the overall packaging volume while maintaining ease of disassembly and assembly.
2Adaptability or versatility
If the head support is positioned high for better child support, then the comfort and safety are improved, but the overall height and volume increase making packaging less efficient
Solution Approach 1:
The head support bracket is designed with movable capability along the backrest, allowing dynamic adjustment of the head support position. During use, the head support can be positioned high for optimal child support, while during packaging, the entire assembly can be collapsed to a compact height. The locking mechanism enables the system to switch between these two states.
Solution Approach 2:
The head support wings nest into the backrest wings through the accommodating holes, creating a compact configuration that minimizes packaging volume. This nested structure allows the head support to be positioned low during packaging without compromising its functionality during use.
3Ease of operation
If the head support bracket is made detachable for easier packaging, then the ease of packaging is improved, but the device complexity increases due to additional connection mechanisms
Solution Approach 1:
The detachable connection mechanism is merged with the existing locking mechanism of the car seat. The head support bracket utilizes the same locking grooves and locking pins that are already present in the backrest structure, combining multiple functions into a single integrated system. This approach enables easy detachment for packaging while avoiding the need for separate complex connection mechanisms.

AI summary
The invention discloses a baby car seat, which comprises a seat, a backrest with a lower portion being detachably connected with a rear portion of the seat, and a head support detachably connected with an upper portion of the backrest. The backrest comprises a backrest body and a pair of backrest wings extending forwards from a left end and a right end of the backrest body respectively. The head support comprises a head support body and a pair of head support wings respectively extending forwards from a left side and a right side of the head support. Two accommodating holes respectively are opened on a left part and a right part of the backrest body, and the shape and mutual distance of the two accommodating holes are matched with that of the two head support wings. When the head support is accommodated between the pair of backrest wings, the two accommodating holes respectively are used for inserting the corresponding head support wings therein. When it is desired to package and transport the car seat, the head support is located between the two backrest wings and the backrest body, and the two head support wings just are inserted into the two accommodating holes of the backrest body and further stacked up with the seat, thus, the height of the car seat is reduced, the volume of encasement is reduced and the quantity of encasement is increased.
