Two-Section Child Car Seat Base for Lower-Cost Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current car seat bases for children are costly due to complex construction methodologies, resulting in high production costs for the entire seat.
Innovation Solution
A method for manufacturing a car seat base using two interconnected sections with shape-coupling flanks and recesses, allowing for simplified assembly with fewer pieces, utilizing plastic molding with smaller molds to reduce costs and facilitate easy coupling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If complex construction methodologies are used for car seat bases, then structural strength and reliability are improved, but manufacturing cost increases
Solution Approach 1:
The base is divided into two separate sections (first section and second section) that can be manufactured independently using smaller molds and then assembled together. This segmentation allows for simpler, less expensive manufacturing processes while maintaining the overall structural integrity through the coupling mechanism between sections.
2Stability of the object's composition
If multiple pieces are used to construct the base, then structural integrity is improved, but assembly complexity increases
Solution Approach 1:
Two separate base sections are merged into a single functional unit through a coupling mechanism involving flanks and recesses. The first section has a flank that couples with a recess in the second section, creating a unified structure that maintains structural integrity while allowing for simpler manufacturing of individual components.
3Productivity
If traditional molding methods are used, then production capability is maintained, but manufacturing cost increases
Solution Approach 1:
The base is segmented into two sections that can be manufactured using smaller, less expensive molds. This segmentation maintains production capability by allowing parallel manufacturing of sections while reducing the cost and complexity of individual molding operations compared to producing a single large base component.

AI summary
A method for implementing a supporting base (1) of a car seat, the latter including said base apt to rest onto a seat of such vehicle and apt to support an upper structure (16) apt to receive and retain a child, the base comprising a first (2) and a second (3) portion, the first sitting portion (2) being apt to rest onto the seat sitting and the second backrest portion (3) being apt to rest onto the backrest of such seat. It is provided to implement such base in at least two sections (20, 21), each section (20, 21) comprising a portion of the base portion and a portion of the sitting portion of the base, said sections being then coupled therebetween and constrained so as to implement the above-mentioned base. The so-obtained base and the seat equipped with such base are also claimed.
