Child Safety Seat ISOFIX Pivot Mount for Compact Storage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional child safety seats with ISOFIX fixing devices protrude outwardly, making them inconvenient to store as the fixing members must be connected to the vehicle's fixing rods, which obstructs storage.
Innovation Solution
A child safety seat design featuring a pivotally connected fixing device with rotating members that can be accommodated into recesses on the base, allowing the fixing members to be securely stored when not in use, conforming to the ISOFIX standard.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the ISOFIX fixing member protrudes from the base outwardly to connect to the vehicle's fixing rod, then the connection function is improved, but the storage convenience deteriorates
Solution Approach 1:
The fixing member is designed to be rotatable relative to the base through a pivot axle, allowing it to dynamically change position between protruding (for connection) and retracted (for storage) states. This dynamic capability resolves the contradiction by enabling the same component to serve both connection and storage needs at different times.
Solution Approach 2:
The fixing member can be rotated to nest within or alongside the base structure during storage, reducing the overall footprint. The pivot mechanism allows the fixing member to be positioned inside the base's boundary when not in use, effectively nesting the connection component within the main body.
2Ease of operation
If the fixing device is designed with protruding fixing members for easy connection, then the ease of operation is improved, but the device complexity increases
Solution Approach 1:
The pivot axle mechanism adds minimal structural elements while enabling the fixing member to rotate between positions. This simple dynamic joint allows the fixing member to be positioned as needed without requiring multiple separate components or complex adjustment mechanisms.
Solution Approach 2:
The same fixing member serves multiple functions: it protrudes for connection to the vehicle's fixing rod, rotates to accommodate during storage, and can be positioned at different angles for assembly and disassembly. This multi-functionality reduces the need for additional specialized components.
3Ease of operation
If the fixing member is made rotatable on the pivot axle, then the storage convenience is improved, but the device complexity increases
Solution Approach 1:
A single pivot axle provides the rotational capability needed for storage while maintaining structural simplicity. The pivot mechanism allows the fixing member to rotate freely between positions without requiring motors, sensors, or complex control systems.
Solution Approach 2:
The fixing device is segmented into the base, pivot axle, and fixing member as separate but connected components. This segmentation allows the rotating fixing member to be independently positioned while the base remains stable, simplifying both the rotation mechanism and the overall assembly.

AI summary
A child safety seat is adapted to be disposed on a vehicle seat and the vehicle seat comprises a fixing rod. The child safety seat comprises a base, a seat body and a fixing device. An assembling direction is defined on the base and the base is capable of being disposed on the vehicle seat. A facing direction is defined on the seat body and the seat body is assembled on the base along the assembling direction. The fixing device is pivotally connected to the base by a pivot axle and used for connecting with the fixing rod. An axial direction of the pivot axle is perpendicular to the assembling direction and the facing direction. Accordingly, the fixing member of the fixing device of the child safety seat can pivot with respect to the base between an accommodating position and a using position.
