Adjustable Child Safety Seat Belt Slot Blocking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing child safety seat assemblies are not adjustable and cannot be securely restrained in different positions, limiting their versatility and safety when used in vehicles.
Innovation Solution
A child safety seat assembly with a base and seat that includes protruding sidewalls and anchoring slots, allowing the seat to be adjusted between erected and reclined positions, with the sidewalls obstructing unused slots to prevent erroneous safety belt insertion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the seat assembly is designed with fixed anchoring slots for safety belt restraint, then the seat can be securely restrained in one configuration, but it cannot be restrained if placed in a different position
Solution Approach 1:
The seat assembly is designed with a movable mechanism that allows the seat to be adjusted between different positions (erected and reclined) relative to the base. The anchoring slots are positioned on the seat such that they move with the seat, and the base includes protruding sidewalls that selectively obstruct certain slots based on the seat position, enabling reliable restraint in multiple configurations
Solution Approach 2:
The anchoring system is segmented into multiple slots positioned at different locations and orientations. The base sidewalls act as selective blockers that prevent the safety belt from engaging with obstructed slots. This segmentation allows the system to provide reliable restraint in authorized positions while preventing misuse in unauthorized positions
2Adaptability or versatility
If multiple anchoring slots are provided for different positions, then the seat can be restrained in various positions, but erroneous operations for securing the seat assembly can occur
Solution Approach 1:
The base includes protruding sidewalls positioned to preemptively block certain anchoring slots when the seat is in unauthorized positions. This preliminary anti-action prevents the safety belt from being incorrectly inserted into obstructed slots, thereby preventing erroneous operations before they can occur. The sidewalls act as physical guides that only allow correct belt insertion when the seat is in the proper position

AI summary
A child safety seat assembly comprises a base including a plurality of protruding sidewalls, and a seat movably assembled with the base including a plurality of anchoring slots adapted to retain a portion of a safety belt, wherein seat is movably adjustable between an erected position and a reclined position relative to the base. Some of the anchoring slots can be selectively obstructed by the sidewalls of the base when the seat is adjusted to a different inclination relative to the base. As a result, erroneous operations for securing the seat assembly with a safety belt can be prevented, and the seat assembly can be safer in use.
