Multi-position chair with tiltable, rotatable and slidable seat shell
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Vehicular child seats are difficult to secure or release in cramped smaller vehicles due to their design, which prioritizes safety but complicates transfer and use in different environments.
Innovation Solution
A multi-position chair with a tiltable, rotatable, and slidable seat shell, featuring a base assembly with tilt, swivel, and slide support mechanisms, allowing the seat to pivot, rotate, and move linearly, facilitating easy installation and removal from vehicles and strollers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If child seat is designed with safety safeguards, then child safety is improved, but ease of securing and releasing child is worsened
Solution Approach 1:
The child seat incorporates dynamic movement capabilities including tilting forward and rotating to multiple positions. The seat shell can tilt forward about 90 degrees from upright position and rotate to at least three different positions, transforming a static safety device into a dynamic system that maintains safety while improving accessibility for parents in cramped vehicles
Solution Approach 2:
The child seat is divided into separable components with the seat shell being detachable from the base assembly. This segmentation allows the seat shell to be independently manipulated for tilting and rotating operations, enabling parents to access and release children more easily without compromising the integrated safety restraint system
2Reliability
If child seat is designed for safety, then child protection is improved, but ease of transfer between vehicle and stroller is worsened
Solution Approach 1:
The seat shell's ability to tilt forward and rotate to multiple positions enables dynamic reconfiguration during transfer operations. Parents can tilt the seat forward to access the child or rotate it to facilitate removal, making transfers between vehicles and strollers significantly easier while the safety restraint system remains intact
Solution Approach 2:
The detachable seat shell design allows separation of the child-containing portion from the base assembly. This enables parents to remove the entire seat shell with the child for transfer to strollers, or manipulate the seat shell independently to facilitate child removal, simplifying the transfer process while maintaining safety

AI summary
A multi-position chair includes a seat shell, elongated seatbelts and a base assembly with pairs of members capable of tilting, rotating and sliding. The seat shell accommodates a child thereon. The seatbelts secure the child to the seat shell. The base assembly includes tilt, swivel and slide support mechanisms. The tilt support mechanism has first and second interfitted members pivotally coupled to one another. The swivel support mechanism has first and second interengaged members rotatably coupled to one another. The slide support mechanism has first and second intercoupled members linearly slidable relative to one another. The second intercoupled member defines a base platform for directly supporting the first intercoupled member in an upright orientation and thereby indirectly supporting, via the first intercoupled member, the first and second interengaged members and the second interfitted member in respective upright orientations.
