Child Safety Seat Base With Pivot Locking Orientation Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional child safety seats have a fixed seat orientation 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 a releasing mechanism allowing the second base to pivot relative to a first base, facilitated by locking and unlocking components, enabling easy adjustment of the seat orientation.
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 without re-installation
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 dynamically change orientation. The pivotal connection enables rotation between different orientations (e.g., forward-facing, rearward-facing, side-facing) without requiring complete disassembly and re-installation, thus resolving the contradiction between ease of orientation adjustment and structure complexity.
2Adaptability or versatility
If the seat portion is re-installed to change orientation, then the orientation can be changed, but the process is time-consuming and inconvenient
Solution Approach 1:
The pivotal connection mechanism allows quick orientation changes through simple rotation rather than time-consuming re-installation procedures
Solution Approach 2:
The locking component is pre-configured with locking holes at different angular positions on the second base. When the user rotates the second base, the locking component automatically engages with the nearest locking hole, providing preliminary positioning that eliminates the need for precise manual alignment during orientation changes, thus reducing the time required.
3Ease of operation
If a locking mechanism is added to enable orientation adjustment, then the seat can be repositioned easily, but the device becomes more complex
Solution Approach 1:
The locking component is designed to automatically engage with the locking holes through elastic deformation. When the second base is rotated to a new orientation, the elastic portion of the locking component naturally bends and snaps into the next locking hole without requiring additional actuators or complex control mechanisms, thus maintaining simplicity while enabling easy orientation adjustment.
Solution Approach 2:
The elastic portion acts as an intermediary between the user's rotation action and the locking function. It mediates the transition by providing automatic engagement through elastic deformation, eliminating the need for separate locking actuators or complex mechanical linkages, thus resolving the contradiction between ease of operation and device complexity.

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