Hinged Child Restraint Platform for Seated-to-Lying Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing child restraint systems for young children are static, limiting the child's position to a seated orientation and failing to accommodate a comfortable lying position, leading to prolonged use beyond regulatory guidelines and improper use in other settings.
Innovation Solution
A child restraint system with a hinged platform that expands between seated and lying positions, comprising three pivotally connected parts from head to feet, and a slide system with complementary profiles for adjusting the child's position independently of the chassis, allowing for a 100° seated and 160° lying angle.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the child restraint system uses a static seated position, then the structure is simple and stable, but the child's comfort is reduced and prolonged use beyond regulatory guidelines occurs
Solution Approach 1:
The platform is divided into three separately pivotally connected portions (head portion, torso portion, legs portion) that can be independently adjusted. This segmentation allows each section to move to achieve different positions (seated, semi-reclined, fully reclined) while maintaining overall structural integrity through the pivotal connections.
Solution Approach 2:
The system transitions from a static structure to a dynamic one by introducing pivotal connections that allow the platform portions to rotate and adjust. The platform can dynamically change between multiple fixed positions (seated at 100°, semi-reclined at 130°, fully reclined at 160°) while maintaining stability at each position through the chassis constraints.
2Ease of operation
If the restraint system allows lying down position, then child comfort and safety are improved, but the chassis structure becomes more complex
Solution Approach 1:
The position adjustment function is extracted from the main chassis and implemented through a独立的 platform structure with its own pivotal connections. The platform portions can be adjusted independently of the chassis, allowing the chassis to remain simple while the platform provides the complex position adjustment capability.
Solution Approach 2:
The platform acts as an intermediary between the simple chassis and the complex position adjustment requirement. The pivotal connections on the platform serve as mediators that enable multi-position adjustment without requiring the chassis itself to be complex, isolating the complexity to the platform level.
3Adaptability or versatility
If the platform is hinged on itself for position adjustment, then position flexibility is achieved, but the structural stability may be compromised
Solution Approach 1:
Different portions of the platform have different pivot characteristics tailored to their specific functions. The head portion pivot allows reclining adjustment, the torso portion pivot enables position transitions, and the legs portion pivot facilitates footrest adjustment. Each pivot is designed with appropriate friction and stopping mechanisms to provide stability at desired positions while allowing controlled movement during adjustment.

AI summary
The present invention falls within the scope of removable seats for vehicles, relating in particular to a child restraint system (1) for use in car seats aimed at carrying children in vehicles or strollers, and to the method of use thereof. More particularly, the child restraint system (1), which is the subject of this invention, makes it possible to adjust the position of the restraint system (1), alternating between the lying and sitting positions, suitable for children up to 13 kg (28 lb) and age from 0 to 15 months, depending on their size. Thus, the child restraint system (1) comprises a chassis (2), a platform (3) hinged on the chassis (2), the platform (3) having an upper part (6) connected to the chassis (2), a middle part (7) and a lower part (8), the said lower part (8) movable by means of a slide system (4) containing a notch (11).
