Tiltable Child Seat Base With Locking Pivot for Breastfeeding Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing child seat devices do not facilitate easy breastfeeding for mothers while ensuring the child's safety during travel, as they lack a mechanism to pivot the car seat for convenient access.
Innovation Solution
A tiltable child seat device with a rotatable mounting base and car seat locking mechanism that allows the car seat to be pivoted to a preferred angle for breastfeeding, featuring a base locking mechanism to secure the top section and a car seat locking mechanism to adjust the car seat's orientation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the car seat is fixed in a standard installation position, then the child's safety during travel is ensured, but the mother cannot conveniently access the child for breastfeeding
Solution Approach 1:
The car seat is designed with dynamic positioning capability, allowing it to be adjusted between a standard installation position (for travel safety) and a tilted position (for breastfeeding access). The pivot mechanism enables the seat to move from a fixed state to a tilted state and back, resolving the contradiction between safety and accessibility.
Solution Approach 2:
The mounting base is divided into separate functional components: a base portion that remains stationary on the vehicle seat, and a top portion that can rotate relative to the base. This segmentation allows the car seat to be decoupled from the fixed mounting position while maintaining secure attachment, enabling access without compromising safety.
2Ease of operation
If the car seat is tilted to allow breastfeeding access, then the mother can conveniently reach the child, but the child's safety during travel may be compromised
Solution Approach 1:
The system provides dynamic positioning with defined states: an upright position for safe travel and a tilted position for access. The locking mechanism ensures the seat remains securely in either position, preventing unintended movement that could compromise safety while enabling convenient access when needed.
Solution Approach 2:
The car seat is designed with preliminary positioning features including stops and guides that ensure proper orientation before locking. The mounting structure is pre-configured to maintain safe angles during travel, so when tilted for breastfeeding, the child remains in a safe position, and when returned to travel position, safety is automatically restored.
3Reliability
If a locking mechanism is added to secure the car seat at different positions, then the safety during travel is maintained, but the device complexity increases
Solution Approach 1:
The locking mechanism is designed to be self-actuating through the weight of the car seat and child. When the seat is positioned correctly, gravity and friction automatically engage the locking features, eliminating the need for manual locking operations or complex control systems while maintaining safety.
Solution Approach 2:
The mounting base includes intermediary locking components such as pins, notches, and friction surfaces that mediate between the movable car seat and the fixed base. These simple mechanical intermediaries provide secure locking without requiring complex mechanisms, resolving the contradiction between safety and simplicity.
4Ease of operation
If the mounting base is made rotatable to facilitate breastfeeding, then the ease of operation is improved, but the stability of the installation is reduced
Solution Approach 1:
The mounting base incorporates controlled dynamics with defined stable states. The rotatable top portion can be moved between positions but is equipped with locking features that create stable equilibrium points during travel and during breastfeeding access, preventing unintended movement while maintaining adjustability.
Solution Approach 2:
The mounting structure includes beforehand cushioning elements such as friction surfaces, damping features, and mechanical stops that prevent excessive rotation or unintended movement. These elements cushion against instability while allowing intentional positioning changes, maintaining both adjustability and installation stability.

AI summary
A tiltable child seat device includes a mounting base having a top section rotatably attached to a bottom section and the mounting base has a plurality of stops. A base locking mechanism is movably integrated into the bottom section to engage a respective one of the plurality of stops thereby inhibiting the top section from rotating. A car seat is provided with a car seat base pivotally disposed in the top section and a seat attached to the car seat base to accommodate a child. The car seat is pivotal in either direction in the mounting base to facilitate a mother to breastfeed the child while the mother is sitting next to the car seat. The car seat has a plurality of stops integrated into the car seat base. A car seat locking mechanism is movably integrated into the mounting base to engage a respective stop in the car seat.
