Child Safety Seat Modular Latching Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current child safety seat designs are complex and inconvenient to operate when attaching to different carrier structures like bases and stroller frames.
Innovation Solution
A child safety seat with a modular latching unit featuring two pairs of latches and a release handle, allowing secure engagement and disengagement with both base and stroller frames using a simplified mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional attachment mechanisms are used for child safety seats, then the seat can be securely attached to bases and stroller frames, but the construction becomes relatively complex and inconvenient to operate
Solution Approach 1:
The attachment mechanism is divided into separate functional components: latches (first and second) that can independently engage with different carrier structures, and a release handle that operates both latches. This segmentation allows each component to be optimized for its specific function while simplifying the overall construction and operation.
2Reliability
If conventional attachment mechanisms are used for child safety seats, then the seat can be securely attached to bases and stroller frames, but the operation becomes inconvenient
Solution Approach 1:
The release handle merges the operation of both first and second latches into a single action. When the user operates the release handle, it simultaneously unlocks both latches, allowing the seat to be quickly detached from either a base or stroller frame without requiring separate operations for each latch.
3Adaptability or versatility
If a single attachment mechanism is designed to work with both bases and stroller frames, then versatility is improved, but the mechanism becomes more complex
Solution Approach 1:
The attachment mechanism is designed with universal functionality to work with different carrier structures. The first latch engages with bases while the second latch engages with stroller frames, allowing the same seat to be securely attached to multiple types of carriers. This multi-functionality is achieved through the dual-latch design that can adapt to different attachment points and structures.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution provides a convenient and secure attachment system that simplifies the installation and removal of the child safety seat on various support structures, enhancing usability and safety.
Implementation Method 1
A child safety seat with a modular latching unit featuring two pairs of latches and a release handle, allowing secure engagement and disengagement with both base and stroller frames using a spring-biased mechanism for easy operation.

AI summary
A child safety seat comprises a seat shell, two first latches, two second latches and a release handle. An underside of the seat shell has two protruding rails, each of which having an inner side surface facing a gap delimited between the two rails, and an outer side surface opposite to the inner side surface. The two first latches are assembled with the rails, and respectively protrude from the inner side surfaces of the two rails to engage with a base. The two second latches are assembled at positions adjacently opposite to the first latches, and respectively protrude from the outer side surfaces of the two rails to engage with a stroller frame. The release handle is operatively connected with the first and second latches at the two rails, and is operable to switch the first and second latches from a locking to unlocking state.
