Child Safety Seat Base Locking Structure for Pivot Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional child safety seats lack the ability to easily adjust the orientation of the seat portion after installation, making it inconvenient for caregivers to place or care for children, as adjustments require reinstallation of the seat or base components.
Innovation Solution
A base structure for a child safety seat featuring a first and second base, locking components, and a releasing mechanism that allows the second base to pivot relative to the first, enabling easy adjustment of the seat orientation through a sliding locking component and operating assembly, driven by a handle and linking components, with a resilient component for locking and unlocking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the seat portion is fixed on the base portion after installation, then the installation stability is improved, but the ease of operation deteriorates because the orientation cannot be adjusted without reinstallation
Solution Approach 1:
The patent applies the dynamics principle by transforming the fixed connection between the seat portion and base portion into a movable connection. The locking component can slide between locked and unlocked positions, allowing the seat portion to pivot relative to the base portion. This enables dynamic adjustment of orientation while maintaining stability when locked, resolving the contradiction between fixed stability and adjustable ease of operation
Solution Approach 2:
The patent segments the connection system into distinct functional components: the locking component, locking holes, and releasing mechanism. This segmentation allows independent optimization of each component - the locking component provides stable engagement when locked, while the releasing mechanism enables easy unlocking for adjustment, thus resolving the contradiction between stability and ease of operation
2Ease of operation
If a locking mechanism is added to enable orientation adjustment, then the ease of operation is improved, but the device complexity increases
Solution Approach 1:
The patent applies the self-service principle through the resilient component that automatically returns the locking component to its locked position after being pushed by the releasing mechanism. The locking component self-engages with the locking holes without requiring additional actuation, and the resilient component self-restores the locking component, reducing overall system complexity while maintaining ease of operation
Solution Approach 2:
The patent uses the resilient component as an intermediary between the releasing mechanism and the locking component. Instead of directly connecting the releasing mechanism to the locking component, the resilient component mediates by pushing the locking component to disengage and then automatically returning it to the locked position, simplifying the overall mechanism while enabling easy operation

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables caregivers to easily adjust the seat orientation between forward- and rearward-facing positions without reinstallation, enhancing convenience and usability by allowing the seat body to pivot with the second base, facilitating child placement and care.
Implementation Method 1
a resilient component for pushing the locking component to be engaged with the locking hole
Implementation Method 2
A pivoting shaft protrudes from the bottom portion of the second base, and at least a portion of the pivoting shaft is pivotally inserted into the insertion hole

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) and located above the first base (1). A locking hole (21) is formed on a bottom portion of 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).
