Child Safety Seat Base Locking Structure for Pivoting Orientation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional child safety seats have fixed seat orientations that cannot be easily adjusted, requiring re-installation for orientation changes, which is inconvenient.
Innovation Solution
A base structure for a child safety seat with a pivotally connected second base and locking mechanism, allowing the seat orientation to be adjusted by disengaging the locking component from the locking hole using a releasing mechanism, facilitated by an operating assembly with a driving component and resilient component for easy pivoting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the seat portion is fixed on the base portion, then the installation is simple and stable, but the orientation cannot be adjusted for easy access
Solution Approach 1:
The patent applies the dynamics principle by making the second base pivotally connected to the first base, allowing the seat portion to rotate between a first orientation (for easy access) and a second orientation (for compact storage). This dynamic configuration enables orientation adjustment without requiring complete disassembly and reinstallation, thus improving ease of operation while maintaining reasonable structural complexity through the use of a pivotal connection mechanism with locking components.
2Adaptability or versatility
If the orientation is adjusted by re-installation, then the orientation can be changed, but the process is time-consuming and inconvenient
Solution Approach 1:
The patent applies preliminary action by pre-configuring the pivotal connection mechanism with locking holes and locking components that allow quick orientation changes. The locking components are designed to engage with the locking holes in different positions, enabling the seat portion to be rotated between orientations and locked in place without requiring time-consuming disassembly and reinstallation processes.
Solution Approach 2:
The dynamics principle enables quick orientation adjustment by allowing the second base to pivot relative to the first base around a pivotal axis. The locking mechanism permits the seat portion to be rotated to different orientations and secured quickly, reducing the time required for orientation adjustment compared to complete reinstallation.
3Ease of operation
If the second base is pivotally connected to the first base, then the orientation can be adjusted, but the locking mechanism adds structural complexity
Solution Approach 1:
The patent applies segmentation by dividing the locking mechanism into separate locking components and locking holes positioned at different locations. The locking components are disposed at different positions on the first base, with corresponding locking holes on the second base, allowing independent engagement at each position. This segmented approach enables orientation adjustment while keeping each individual locking element relatively simple in structure.

AI summary
A base structure (100) adapted for a seat body of a child safety seat is provided and includes a first base (1), a second base (2), a locking component (3) and a releasing mechanism (4). The second base (2) is pivotally connected to the first base (1). A locking hole (21) is formed on the second base (2). The locking component (3) is slidably disposed on the first base (1). An end of the locking component (3) is for engaging with an end of the locking hole (21). An end of the releasing mechanism (4) is located inside the second base (2) and slidably disposed on another end of the locking hole (21). The releasing mechanism (4) is operated to push the locking component (3) to disengage from the locking hole (21) for unlocking the second base (2), so as to allow the second base (2) to pivot relative to the first base (1).
