Adjustable Child Seat Base for Leg Room and Recline
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional child safety seats lack adequate leg room adjustment, leading to discomfort and the need for premature transitions to forward-facing seats as children grow, as they are not designed to accommodate varying ages and sizes effectively.
Innovation Solution
A child safety seat assembly with a base featuring an adjustable platform that allows the child seat to be moved back and forth, providing adjustable leg room and recline angles through a latch and release mechanism, enabling secure attachment and detachment while accommodating different child sizes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional attachment structures are used to fasten the child seat with the base, then the seat is securely fastened, but the child seat cannot be adjusted to accommodate growing children's leg room needs
Solution Approach 1:
The base incorporates a movable platform that can be adjusted along the longitudinal axis, transforming the static attachment structure into a dynamic one. This allows the child seat to be repositioned to different distances from the vehicle seat back, providing adjustable leg room while maintaining secure attachment through engagement features at various positions.
Solution Approach 2:
The base is divided into a stationary portion and a movable platform portion. The stationary portion maintains the attachment to the vehicle seat, while the movable platform can be independently adjusted. This segmentation allows the leg room adjustment function to be added without compromising the security of the overall attachment structure.
2Adaptability or versatility
If the child seat is designed for infants from birth to 12 months, then it accommodates small infants, but it lacks the adjustments needed for older children up to 24 months
Solution Approach 1:
The movable platform with engagement features at multiple positions enables the base to adapt to different age groups and child sizes. Parents can easily reposition the platform along the longitudinal axis as the child grows, extending the usable life of the child seat from infants to toddlers without requiring a different seat model.
3Adaptability or versatility
If the child seat is fixed in position on the base, then the installation is simple and secure, but the leg room cannot be adjusted as the child grows
Solution Approach 1:
The system transitions from a fixed position to a dynamically adjustable position while maintaining reliability. The movable platform incorporates engagement features that securely lock at predetermined positions along the longitudinal axis, ensuring that the attachment remains as secure as a fixed installation while allowing for leg room adjustment when needed.
Solution Approach 2:
By separating the attachment function (stationary portion) from the adjustment function (movable platform), the design maintains the reliability of secure attachment while adding the versatility of leg room adjustment. The engagement features ensure that when the platform is locked at any position, the security of attachment is maintained.

AI summary
A child safety seat assembly includes a child seat and a base. In one embodiment, the base can include a first portion having a bottom adapted to provide stable resting support, and a second portion extending upward from the first portion. The child seat can be installed on the base, wherein the child seat has a seat portion and a seatback, and is movable relative to adjust a distance between the seat portion and a region of the second portion in front of the seat portion. In other embodiments, a base suitable for use with a child seat is also described. The base can comprise a shell body, and an adjustable platform movably assembled on an upper guide surface of the shell body, wherein the adjustable platform is adapted to attach with the child seat.
