Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing child safety carriers with isofix interfaces face challenges in efficiently adjusting to fit various car seat configurations, leading to inconvenient installation.
Innovation Solution
A telescopic adjustment structure featuring a fixing device with movable locking members that can lock or unlock with multiple positioning parts on a base, allowing for adjustable length adjustment of the fixing device to better fit isofix interfaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed-length fixing device is used, then the structure is simple, but it cannot adapt to various car seat configurations
Solution Approach 1:
The fixing device transitions from a fixed-length design to a telescopic design with movable components. The fixing device includes a first fixing part and a second fixing part that can move relative to each other along the sliding direction, enabling dynamic length adjustment to adapt to different car seat configurations while maintaining operational simplicity through guide slots and locking mechanisms
2Ease of operation
If the fixing device length is adjustable, then compatibility with isofix interfaces is enhanced, but the installation complexity increases
Solution Approach 1:
The locking member is designed to automatically lock with the positioning parts when the first and second fixing parts are at the desired position. The elastic component provides automatic resetting functionality, allowing the locking member to return to its initial state after locking, enabling users to complete installation without complex manual adjustment procedures
Solution Approach 2:
The locking member acts as an intermediary mechanism between the movable fixing parts and the base. It cooperates with positioning parts on the base to secure the telescopic components at specific positions, simplifying the installation process by providing automatic positioning and locking functionality
3Measurement precision
If multiple positioning parts are added for precise adjustment, then positioning accuracy is improved, but the device complexity increases
Solution Approach 1:
The locking member serves multiple functions: it locks with positioning parts to secure the fixing device, works with the elastic component for automatic resetting, and cooperates with guide slots to maintain proper alignment. This multi-functionality reduces the need for separate components for each positioning function, maintaining positioning accuracy while controlling overall device complexity

AI summary
A telescopic adjustment structure arranged on a base includes a fixing device movably arranged on the base and having a plurality of positioning parts. a locking member movably arranged on the base and capable of locking the fixing device, wherein the fixing device is configured to be locked to different corresponding positions of the base by the locking member cooperating with different positioning parts, or the fixing device is movable relative to the base by the locking member separated from the positioning parts, and an elastic member on the locking member. The locking member is arranged elastically telescopic on the base. The elastic member is configured to bias the locking member toward the positioning parts in a first direction. A position of the fixing device relative to the base is telescopically adjustable in a second direction.
