Adjustable Child Seat Back Insert for Small-Child Support
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Typical booster seats are often too large for smaller children, providing insufficient back support, and the fixed distance between the seating surface and seat back can hinder their use, while the harnesses on these seats can be cumbersome and difficult to remove.
Innovation Solution
A child seat with an adjustable seat back insert that can be positioned closer to the front edge, allowing for multiple support configurations to accommodate different child sizes and growth stages, and a harness system that can be easily installed or removed based on the seat configuration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the seat back is positioned farther from the front edge to accommodate larger children, then larger children can use the seat, but smaller children cannot reach or touch the seat back
Solution Approach 1:
The seat back is made adjustable between a first position spaced a first distance from the front edge and a second position spaced a second distance from the front edge, allowing the distance to be dynamically changed based on the child's size. This resolves the contradiction by enabling the seat back to be close to small children when in the second position and far from large children when in the first position.
Solution Approach 2:
The seat back is divided into a first portion and a second portion that can move relative to each other. The first portion remains fixed while the second portion can be adjusted to different positions, allowing the seat back to accommodate different child sizes while maintaining structural integrity.
2Reliability
If the seat back height is increased to provide support for smaller children, then back support is sufficient, but comfort is reduced for larger children
Solution Approach 1:
The seat back height is made adjustable between a first height that provides sufficient support for small children and a second height that is comfortable for large children. This allows the height to be dynamically adjusted based on the child's size, resolving the contradiction between support sufficiency and comfort.
Solution Approach 2:
Different portions of the seat back are designed with different heights and configurations to serve different needs. The adjustable portion can be positioned to provide appropriate support for small children while the overall structure accommodates larger children, allowing local optimization for different user groups.
3Ease of operation
If the harness is made removable to improve convenience, then installation and removal becomes easier, but structural complexity increases
Solution Approach 1:
The harness system is segmented into a first portion and a second portion that can be independently adjusted and removed. The second portion including the harness can be removed from the first portion, allowing easy installation and removal while maintaining a relatively simple overall structure through modular design.
Solution Approach 2:
The harness system is designed to be dynamically adjustable and removable. The harness can be easily installed and removed through simple mechanisms, providing convenience while the modular dynamic structure actually reduces overall complexity compared to fixed non-removable designs.

AI summary
A child seat has a seat base with a seating surface, a front edge, and a back end. A back support surface of the child seat is generally inclined relative to the seating surface. A seat bight is formed at the juncture between the seating surface and the back support surface. The seat bight is adjustable between a first bight position spaced a first distance from the front edge of the seat base and a second bight position spaced a second distance from the front edge of the seat base. The second distance is less than the first distance. A seat back insert can be provided that is attachable to the seat base in one or more insert positions defining one or more of the bight positions. The insert can create the back support surface at one or more position relative to the front edge. The seat base can also have a back wall creating the back support surface further from the front edge when the insert is removed.
