Foldable Child Seat With Nested Backrest For Space Saving
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing adjustable child devices for vehicles are bulky and cannot be folded, occupying large storage space when not in use.
Innovation Solution
The design includes a first seat portion with a chamber, a foldable second seat portion that can be received within the first seat portion, and a belt engaging element with a positioning recess and protrusion system, allowing the device to be folded and unfolded, with additional features like a pivoting shaft and soft supporting components for comfort and ventilation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the adjustable child device is designed with a fixed structure to ensure safety and stability, then the reliability is improved, but the device occupies large storage space and cannot be folded
Solution Approach 1:
The child device is divided into separate components: a base unit with seat belt receptacle and a removable seat portion with back rest. This segmentation allows the back rest to be folded or removed, reducing storage space while maintaining safety functionality when assembled
Solution Approach 2:
The back rest is designed with foldable capability, transitioning from a fixed position during use to a folded position for storage. This dynamic structure allows the device to adapt between operational reliability and compact storage requirements
2Ease of operation
If the adjustable child device includes a back rest for comfort, then the comfort is improved, but the device becomes bulky and cannot be folded
Solution Approach 1:
The back rest is separated as a distinct component that can be folded or removed, allowing comfort features to be present during use but compact during storage
Solution Approach 2:
The foldable back rest can be nested or folded into a compact configuration within or adjacent to the base unit, reducing overall storage volume while maintaining comfort when deployed
3Ease of manufacture
If the adjustable child device uses simple structure to reduce complexity, then the ease of manufacture is improved, but the device cannot be folded to save space
Solution Approach 1:
Simple hinge or pivot mechanisms are incorporated into the base unit to enable the back rest to fold or detach, adding folding capability without significantly increasing structural complexity
Solution Approach 2:
The device is designed as modular components that can be easily manufactured separately and assembled, with the foldable connection point being a simple mechanical interface

AI summary
An adjustable child device includes a first seat portion, a second seat portion and a belt engaging element. The second seat portion is foldable relative to the first seat portion between an unfolded position and a folded position and at least partially received in the first seat portion when the second seat portion is located at the folded position. The second seat portion and the first seat portion are located on a horizontal plane to form a seat part when the second seat portion is located at the unfolded position. A positioning protrusion is formed on a lateral side of the seat part. The belt engaging element is installed on a lateral side of the seat part. A positioning recess is formed on the belt engaging element for engaging with the positioning protrusion. The adjustable child device can be folded when it is not in use, which saves storage space.
