Telescopic ISOFIX Locking Structure for Child Seat Fit Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing child safety carriers with isofix interfaces face challenges in conveniently and efficiently adjusting the length of the fixing device to securely fit with various car seats, complicating the installation process.
Innovation Solution
A telescopic adjustment structure comprising a fixing device and a locking member that allows for adjustable locking and unlocking with positioning parts, facilitated by a driving assembly and elastic members, enabling the fixing device to be telescopically adjusted to fit different isofix interfaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the fixing device is made fixed and non-adjustable, then the installation structure is simple and reliable, but it cannot adapt to different car seat isofix interfaces
Solution Approach 1:
The fixing device transitions from a fixed state to a movable state through the locking member mechanism. The locking member can engage with positioning parts to fix the fixing device at specific positions, or disengage to allow movement, enabling the device to adapt to different car seat interfaces while maintaining structural simplicity
Solution Approach 2:
The fixing device is divided into multiple positioning parts at different locations, allowing the locking member to engage with different segments depending on the required length adjustment. This segmentation enables versatile adaptation without requiring a completely different structure for each car seat type
2Ease of operation
If the fixing device is made telescopic and adjustable, then it can fit different isofix interfaces, but the installation process becomes more complicated
Solution Approach 1:
The locking member is designed to automatically engage with the positioning parts when the fixing device is moved to the desired position, eliminating the need for manual locking operations. The elastic member provides automatic resetting force, making the entire adjustment and locking process self-service oriented and simplifying installation
Solution Approach 2:
The locking member acts as an intermediary between the movable fixing device and the base. It simplifies the interaction by providing a single engagement point that controls the entire locking mechanism, allowing users to install the child seat without dealing with complex adjustment procedures
3Adaptability or versatility
If multiple positioning parts are provided for different lengths, then the adaptability to various car seats is improved, but the structure becomes more complex
Solution Approach 1:
The locking member is designed with universal functionality to engage with multiple different positioning parts along the base. A single locking member structure serves multiple purposes by interacting with different positioning parts to achieve various length adjustments, reducing the need for multiple specialized locking mechanisms

AI summary
The disclosure provides a telescopic adjustment structure including a fixing device movably arranged on a base and a locking member movably arranged on the base and capable of locking the fixing device, a plurality of positioning parts cooperating with the locking member are arranged on the fixing device, and the fixing device is locked to different corresponding positions corresponding to the base by the locking member in locked cooperating with different positioning parts, or the fixing device is movable corresponding to the base by the locking member separated from the positioning parts. In the telescopic adjustment structure of the disclosure, the locking member and the fixing device are locked or unlocked by movement of the locking member, such that the fixing device may be adjusted in length in respect to the base with simple structure and more convenient installation.
