Child Safety Seat Latching Unit for Base and Stroller Attachment
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 spring-biased mechanism for easy operation.
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 complex and operation becomes inconvenient
Solution Approach 1:
The attachment mechanism is divided into separate latch components (first latches for base attachment, second latches for stroller frame attachment) that can independently engage with different carrier structures. Each latch is a discrete element that can be assembled with the rails, allowing the system to attach to multiple types of carriers without requiring a single complex universal mechanism
Solution Approach 2:
The same rail and latch structure serves multiple functions: the first latches engage with bases while the second latches engage with stroller frames. This multi-functional design allows a single attachment mechanism to securely attach to different types of carrier structures without requiring separate mechanisms for each carrier type
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 is operatively connected to both the first latches and second latches, allowing a single operating action to simultaneously engage or disengage both sets of latches. This merging of control functions enables the user to attach or detach the entire seat from either base or stroller frame using one simple operation rather than manipulating separate mechanisms
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 simplifies the attachment process, ensuring secure mounting and easy removal of the child safety seat from various support structures, reducing the complexity and effort required for installation and use.

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.
