ISOFIX Connector Adjustment Mechanism for Rotating Safety Seat Bases
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing safety seat bases can only be rotated for rear-facing use with infant seats, limiting their adaptability, and existing adjustment mechanisms for ISOFIX connectors are cumbersome and prone to misuse.
Innovation Solution
A safety seat base with a rotary plate and linkage mechanism that allows for both rear- and forward-facing configurations, featuring a sliding member and engaging mechanism to securely lock and unlock the ISOFIX connector, preventing misuse by ensuring the infant seat can only be detached in the rear-facing position.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a multi-stage adjustment structure with operating members on two sides is used, then the user can adjust the distance between the safety seat and ISOFIX connector, but the structure becomes complex and prone to misuse
Solution Approach 1:
The patent combines the adjustment mechanism and locking mechanism into a single integrated structure. The operating member on one side simultaneously controls both adjustment and locking functions, eliminating the need for separate operating members on both sides. This merging reduces structural complexity while maintaining ease of operation.
Solution Approach 2:
The operating member is designed to perform multiple functions: it controls the adjustment of the ISOFIX connector distance and simultaneously activates the locking mechanism. This multi-functional design simplifies the overall structure by eliminating redundant components while preserving full operational capability.
2Adaptability or versatility
If the safety seat base is designed for rear-facing use only, then the engaging mechanism is simple, but the adaptability to different seating orientations is limited
Solution Approach 1:
The patent introduces a rotary plate mechanism that enables dynamic reconfiguration between rear-facing and forward-facing orientations. The rotary plate can rotate to different positions, allowing the safety seat base to adapt to various seating orientations while maintaining a relatively simple engaging mechanism through controlled rotational movement.
3Reliability
If the sliding member protrudes into the mounting base to abut against the driving member, then the locking is secure, but the structure becomes more complex
Solution Approach 1:
The sliding member is designed to protrude into the mounting base in a nested configuration, where the sliding member fits within the mounting base structure. This nesting approach provides secure locking through the abutment between the sliding member and driving member while minimizing additional structural complexity by utilizing the existing spatial arrangement.

AI summary
A safety seat base includes a mounting base, a rotary plate, an engaging mechanism, and a linkage mechanism. The rotary plate is rotatably arranged on the mounting base and has a first rotation position and a second rotation position. The engaging mechanism is configured to engage the rotary plate with the safety seat body. The linkage mechanism includes a driving member and a sliding member. The driving member is slidably arranged on the mounting base. The sliding member is slidably arranged on the rotary plate. The sliding member at least partially protrudes into the mounting base to abut against the driving member, or the driving member at least partially protrudes into the rotary plate to abut against the sliding member. When the rotary plate is in the first rotation position, the driving member is operable to move and drive the engaging mechanism to be unlocked.
