Child Seat Side Buffer With Magnetic Auto-Deployment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing child safety seats with side impact protection structures often fail to deploy correctly due to their location on the sidewall, leading to inadequate protection during vehicle side collisions as caregivers may forget to deploy the protecting elements.
Innovation Solution
A child safety seat with a side impact protection system featuring a buffering part that can be stowed and deployed via a magnetic retaining mechanism and release mechanism, allowing it to protrude sideways for effective cushioning during collisions, and a latching mechanism to secure it in the deployed position.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the protecting element is located on the sidewall of the child safety seat, then the side impact protection structure can be provided, but the caregiver may forget to deploy the protecting element, resulting in inadequate protection
Solution Approach 1:
The buffering part is designed to deploy automatically through a magnetic retaining mechanism that releases when a child is placed in the seat, eliminating the need for manual deployment by the caregiver. The system serves itself by detecting the presence of the child and activating the protection mechanism automatically.
Solution Approach 2:
The patent replaces the manual mechanical deployment system with a magnetic field-based retaining and release mechanism. The magnetic force holds the buffering part in a retracted position during transport and automatically releases it when the child's weight triggers the release mechanism, substituting human action with magnetic field interaction.
2Volume of moving object
If the buffering part is retracted toward the sidewall for compact storage, then the storage space is optimized, but the protection capability during collision is reduced
Solution Approach 1:
The buffering part transitions from a static retracted position during transport to a dynamic deployed position during use. The magnetic retaining mechanism allows the buffering part to be held compactly when not in use and automatically extends it when needed, creating a dynamic system that adapts between storage and protection modes.
Solution Approach 2:
The buffering part is pre-positioned in a retracted state during transport and storage, and the magnetic retaining mechanism is pre-configured to automatically deploy it when a child is placed in the seat. The system prepares the protection mechanism in advance but only activates it when the specific condition (child presence) is met.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Ensures convenient deployment and compact storage of the side impact protection system, providing enhanced protection for children during vehicle side collisions without requiring manual unlocking by caregivers.
Implementation Method 1
a retaining mechanism configured to hold the buffering part in the first position via a magnetic force
Implementation Method 2
the release mechanism being operable to release the buffering part from the hold of the retaining mechanism by removing the magnetic force

AI summary
A child safety seat includes a seat shell having at least one sidewall, a buffering part connected with the seat shell, the buffering part being movable between a first position corresponding to a stowed state where the buffering part is retracted toward the sidewall and a second position corresponding to a deployed state where the buffering part protrudes sideways from the sidewall, a retaining mechanism configured to hold the buffering part in the first position via a magnetic force, and a release mechanism operatively connected with the retaining mechanism, the release mechanism being operable to release the buffering part from the hold of the retaining mechanism for movement of the buffering part from the first position to the second position.
