Child Safety Seat Sidewall Buffering for Side Collision Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional child safety seats often experience undesirable deformations in the sidewalls during side collisions, which can compromise their protective function.
Innovation Solution
The child safety seat incorporates two side impact protection modules with buffering parts that are pivotally connected to the sidewalls, allowing them to protrude and deform inward during a collision, thereby dissipating impact energy and enhancing protection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If traditional side impact protection structures are used, then side collision energy can be dissipated, but undesirable deformations occur in the sidewalls which compromise protective function
Solution Approach 1:
The side impact protection structure is divided into multiple buffering parts (first, second, and third buffering parts) that can independently deform and absorb energy. Each buffering part is pivotally connected to allow controlled movement, enabling segmented energy absorption while maintaining overall structural integrity and protective function.
Solution Approach 2:
The buffering parts are designed to be movable rather than fixed, allowing them to dynamically respond to collision forces. The pivotal connections enable the buffering parts to rotate and deform in a controlled manner during impact, optimizing energy absorption while preventing harmful deformations of the main sidewall structure.
2Loss of energy
If buffering parts are pivotally connected to allow inward deformation during collision, then impact energy is absorbed and dissipated, but device complexity increases
Solution Approach 1:
The buffering parts utilize pivotally connected elements that function as flexible components within the rigid seat structure. These pivotal connections allow controlled deformation through rotation, providing energy absorption capability while maintaining a relatively simple overall structure that integrates seamlessly with the existing seat framework.

AI summary
A child safety seat (100) includes a seat shell (112) and a buffering part (132). The seat shell (112) includes a backrest portion (118) and two sidewalls (120), the backrest portion (118) having a front surface (118A) facing forward that is suitable to provide support for a child's back, the two sidewalls (120) being respectively disposed at a left and a right side of the seat shell (112) for restricting sideways movements of a child who sits in the seat shell (112), one of the two sidewalls (120) having a sidewall portion (120A) located in front of the front surface (118A). The buffering part (132) is connected with the seat shell (112), the buffering part (132) being operable to protrude sideways at an outer side of the sidewall portion (120A).
