Car Seat Carrier Base Segmentation for Quick Attachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional child car seats often face issues with weight, bulk, difficulty in attachment and removal, and adjusting to accommodate a child's growth, as well as varying vehicle seat profiles and recline angles, which complicates installation and safety.
Innovation Solution
A car seat design featuring a carrier portion that can be releasably attached to a base portion with a tension arm for securing the seat to the vehicle, adjustable angle settings, and a belt path system for easy installation, along with a chest clip, carry handle, and stroller attachment mechanism for enhanced usability and safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional car seats are designed with multiple features (rear-facing attachments, angle adjustments), then functionality and safety are improved, but weight and bulk increase
Solution Approach 1:
The car seat system is divided into two main segments: a base portion that remains in the vehicle and a carrier portion that holds the child. The base contains the rear-facing attachment mechanism and angle adjustment features, while the carrier is lighter and can be easily removed. This segmentation allows the heavy, feature-rich base to stay stationary while the lighter carrier provides portability.
Solution Approach 2:
The rear-facing attachment mechanism and complex adjustment features are extracted from the carrier and placed in the base. This extraction allows the carrier to be simplified and made lighter, while the base assumes the role of housing the heavier, more complex components that don't need to be frequently moved.
2Adaptability or versatility
If conventional car seats incorporate multiple attachment mechanisms and adjustment features, then adaptability to different vehicles and children is improved, but device complexity increases
Solution Approach 1:
The system segments attachment functions: the base has LATCH belt interfaces for vehicle attachment, while the carrier has a simplified latch mechanism that interfaces with the base. This segmentation reduces the complexity of the carrier while maintaining overall system adaptability through the base's multiple attachment options.
Solution Approach 2:
The base portion serves multiple functions: it attaches to the vehicle via LATCH belts, provides angle adjustment for the carrier, and houses storage compartments. This multi-functionality consolidates several features into a single component, reducing overall system complexity while maintaining adaptability.
3Strength
If conventional car seats are designed as integrated units, then structural integrity is improved, but ease of attachment and removal decreases
Solution Approach 1:
The car seat is segmented into a base and carrier that can be easily attached and detached. The base remains permanently installed in the vehicle, maintaining structural integrity for safety, while the carrier can be quickly removed and reattached using a simple latch mechanism operated by a release handle.
Solution Approach 2:
A latch mechanism serves as an intermediary between the carrier and base. This intermediary allows for easy attachment and removal of the carrier while maintaining strong structural connection during use. The latch engages with latch points to secure the carrier to the base during normal operation.
4Ease of manufacture
If conventional car seats lack modular design, then manufacturing simplicity is maintained, but difficulty in adjusting for child growth increases
Solution Approach 1:
The carrier portion is designed with dynamic adjustability features including a five-point harness system that can be repositioned and a chest clip that adjusts to accommodate the child's growth. These dynamic elements allow the same carrier to adapt to different child sizes without requiring manufacturing of multiple carrier models.

AI summary
An car seat that can be quickly attached and detached to a vehicle seat and a stroller. An example embodiment is a car seat that includes a carrier portion, a base portion, and a release handle coupled to the carrier for enabling detachment of the carrier from the base and stroller. The car seat includes a tension arm for releasably clamping a vehicle belt onto the base and tensioning the belt to secure the base portion to a vehicle seat.
