Child Seat Side Wing Mechanism for Smooth Folding Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing child safety seats with fixed side wings fail to provide optimal comfort and safety for children of different ages and sizes, and the inflexible side wings complicate storage, transportation, and testing due to their inability to be folded and opened at will.
Innovation Solution
A side wing adjustment mechanism that includes pins on the headrest and inclined grooves on the side wings, allowing for adjustable height and extension, along with a driving rod and return members to ensure smooth opening and folding, and springs for automatic retraction, enabling the side wings to be folded and opened effortlessly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If side wings are made fixed to provide stable protection, then safety and comfort are improved, but adaptability to different children and ease of storage are worsened
Solution Approach 1:
The side wings are designed to be dynamically adjustable rather than fixed. The adjustment mechanism includes grooves on the backrest and corresponding protrusions on the side wings that allow the side wings to be positioned at different heights and angles, enabling adaptation to children of various sizes while maintaining protective function
2Stability of the object's composition
If side wings are made fixed, then structural stability is improved, but ease of operation for folding and opening is worsened
Solution Approach 1:
The side wings transition from a fixed state to a dynamically adjustable state through a designed mechanism. The grooves and protrusions create guided movement paths that allow easy folding and opening operations while the mechanism itself maintains structural stability during use
Solution Approach 2:
The connection between side wings and backrest is segmented into discrete positioning points along the grooves. This segmentation allows the side wings to be easily detached and repositioned at different locations, facilitating simple folding and opening operations
3Ease of manufacture
If side wings are made fixed, then manufacturing simplicity is improved, but adaptability and operational flexibility are worsened
Solution Approach 1:
The side wing structure incorporates adjustable elements (protrusions and grooves) that enable dynamic positioning. While slightly more complex than a completely fixed structure, the design remains manufacturable using standard fabrication processes and maintains the benefit of adaptability

AI summary
A side wing adjustment mechanism and an adjustable sitting device, the side wing adjustment mechanism includes: a pin arranged on the headrest; and an inclined grooves arranged on the side wing, a distance between a portion of the inclined grooves and the longitudinal center axis gradually decreases in a direction extending from bottom to top toward the headrest along a longitudinal center axis of the backrest, and the pin is slidable along the inclined grooves. According to the application, the side wing can be folded and opened at will, and the structure of the application is more inclusive. During the opening and folding process, puling of the headrest or pushing of the side wing can be performed more smoothly and labor-savingly, and the phenomenon of deflection and jamming can be avoided, such that the opening and folding process of the side wings is smoother.
