Booster Seat Armrest Nesting for Compact Storage and Shipping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional child booster seats with additional features like armrests and cup holders increase their volume, making them less convenient for storage and shipment.
Innovation Solution
The design incorporates armrests and cup holders that can be stored within a seat shell, allowing the booster seat to occupy a smaller volume and be packed in a smaller package, enabling compact storage and reduced shipment costs by matching the outer contour shape of the seat shell.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If armrests and cup holders are added to the booster seat, then functionality and convenience are improved, but volume and storage difficulty increase
Solution Approach 1:
The booster seat is divided into functional modules: the seat shell and the detachable armrests with cup holders. This segmentation allows the armrests to be removed and stored separately, reducing the overall volume during storage while maintaining full functionality during use.
Solution Approach 2:
The armrests are designed to nest within the seat shell when not in use. The storage cavity of the seat shell accommodates the armrests, creating a compact configuration that minimizes volume for storage and shipping purposes.
2Ease of operation
If additional features like armrests are included, then user convenience is improved, but shipping cost increases due to larger package size
Solution Approach 1:
The booster seat transitions between two dynamic states: a deployed state with armrests attached for user convenience, and a compact state with armrests stored in the seat shell for efficient shipping. This dynamic reconfiguration reduces shipping volume and associated costs.
Solution Approach 2:
The armrests can be temporarily 'discarded' (detached) from the main seat structure during shipping, then 'recovered' (reattached) for use. This temporary separation optimizes shipping efficiency without permanently compromising product functionality.
3Stability of the object's composition
If armrests are permanently attached to the seat shell, then structural stability is improved, but storage compactness deteriorates
Solution Approach 1:
The armrests are pre-equipped with attachment mechanisms (such as clips or latches) that enable quick and secure attachment to the seat shell. This preliminary preparation ensures that when the armrests are attached, they provide stable support, yet when detached, they can be compactly stored.
Solution Approach 2:
The armrests are extracted from the permanent structure, allowing them to be removed and stored in the seat shell's storage cavity. This extraction maintains structural stability during use while enabling compact storage when the armrests are not needed.

AI summary
A child booster seat includes a seat shell, and armrests that can be conveniently placed in an outer envelop of the seat shell. The armrests can be placed in a storage cavity of the seat shell, and deployed outside the storage cavity for use. When the armrests are received in the seat shell, the outer envelop of the booster seat can substantially match with the outer contour shape of the seat shell. The booster seat can thereby occupy a smaller volume.
