Child Seat Side Wing Ring Reinforcement for Impact Resistance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing child safety seats are prone to deformation or fracture when subjected to severe impacts, such as collisions or sudden deceleration, due to insufficient strength in the components that interact with the vehicle's seat belt.
Innovation Solution
A side wing assembly for child safety seats that incorporates a strengthening member, made of materials like metal, plastic, or ceramic, which is integrated with the seat belt ring to enhance its strength and withstand external forces up to 5000N, preventing deformation or damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the side wing ring is made of standard material without strengthening, then the device complexity is low and manufacturing is easier, but the strength and resistance to external impact is insufficient
Solution Approach 1:
The patent applies composite materials by combining a strengthening member (made of metal, plastic, or carbon fiber) with the side wing ring structure. The strengthening member is embedded within or attached to the ring, creating a composite structure that provides enhanced strength and impact resistance while maintaining the overall ring geometry and function.
Solution Approach 2:
The side wing ring is segmented into functional components: the outer ring structure and the embedded strengthening member. This segmentation allows the strengthening member to be separately manufactured and then integrated into the ring, enabling enhanced strength without completely redesigning the entire ring structure.
2Reliability
If a strengthening member is added to the ring, then the reliability and safety under impact is improved, but the manufacturing process becomes more complex
Solution Approach 1:
The strengthening member is pre-positioned or pre-formed before final assembly of the side wing ring. This preliminary action allows the strengthening member to be prepared separately with optimal geometry and material properties, then integrated into the ring structure, ensuring reliability while streamlining the manufacturing process.
Solution Approach 2:
The strengthening member is nested within the side wing ring structure, with the strengthening member embedded in or attached to the inner surface of the ring. This nesting approach allows the strengthening member to be integrated into the existing ring geometry without requiring complete disassembly or complex manufacturing processes.
3Force
If the strengthening member is made of high-strength material, then the ability to withstand external force is improved, but the weight of the assembly increases
Solution Approach 1:
The strengthening member is applied locally at critical stress points within the side wing ring rather than throughout the entire structure. This local quality approach provides enhanced force resistance where needed most while minimizing the overall weight increase, as the strengthening is concentrated in specific high-stress regions rather than distributed uniformly.

AI summary
The disclosure provides a child safety seat having a side wing assembly. The side wing assembly includes a ring for a seat belt of a vehicle to pass through. A strengthening member is assembled to the ring to improve the strength of the ring to prevent the ring from being deformed or damaged under impact.
