Pivoting Child Seat Connector for Deceleration Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional child safety seats tend to rotate and tip forward during sudden vehicle deceleration, causing the child to sink and potentially collide with the front seat, leading to injury due to the lack of effective stabilization and balancing mechanisms.
Innovation Solution
A child safety seat design featuring pivotally connected connectors with a damper, such as a torsion spring, and a limiting member to maintain the connector in an initial pivotal position, allowing balanced forward movement and buffering impact forces, while limiting downward rotation to prevent severe collisions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the connector is rigidly fixed to the base, then the connection strength is improved, but the ability to buffer impact forces during sudden deceleration deteriorates
Solution Approach 1:
The connector is pivotally connected to the base via a pivot shaft, allowing it to rotate dynamically during sudden deceleration events. This dynamic connection enables the connector to absorb impact forces through controlled rotation rather than rigid transmission, resolving the contradiction between connection strength and impact buffering capability
Solution Approach 2:
A damper (torsion spring) is pre-installed between the pivot shaft and the base to provide beforehand cushioning. This damper is configured to maintain the connector in an initial pivotal position and provide resistance to rotation, cushioning the impact forces before they can cause harmful effects during sudden deceleration
2Object-affected harmful factors
If the connector is allowed to rotate freely during deceleration, then the impact buffering capability is improved, but the stability of the safety seat deteriorates
Solution Approach 1:
The damper (torsion spring) is pre-configured to maintain the connector in an initial pivotal position, providing beforehand cushioning that resists excessive rotation. This ensures the connector rotates only within controlled limits to buffer impact while maintaining seat stability
Solution Approach 2:
The limiting member is installed to preliminarily prevent excessive downward rotation of the connector. By providing preliminary anti-action against excessive rotation, the limiting member ensures that the connector buffers impact forces without compromising the overall stability of the safety seat
3Stability of the object's composition
If the connector is constrained to remain in initial position, then the seat stability is improved, but the ability to move forward balancedly during deceleration deteriorates
Solution Approach 1:
The pivotable connector allows controlled forward movement during deceleration, enabling the seat to move forward balancedly rather than being rigidly constrained. This dynamic capability prevents harmful forward tipping while maintaining stability through the damper and limiting member
