Multi-Mode Child Carrier with Telescopic Frame and Segmented Seat
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional child carrying devices are bulky and limited in functionality, failing to adequately serve as both strollers and high chairs due to complex reconfiguration processes and lack of height adjustment, restricting their use in various environments and terrains.
Innovation Solution
A collapsible child carrying device with a frame-mounted seat that includes adjustable link arms and telescopic side bars, allowing it to be configured as a stroller, child back carrier, or high chair, with wheels that can be folded for compact storage and travel.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a stroller is designed with a rotating hub to allow seat rotation, then the child can face different directions, but the device remains large and bulky even when folded
Solution Approach 1:
The device is divided into separable components: the seat unit can be detached from the stroller frame and converted into a standalone child back carrier. This segmentation allows the seat to be reconfigured without the bulk of the stroller frame, enabling compact folding while maintaining orientation versatility.
Solution Approach 2:
The seat unit serves multiple functions: it can be used in stroller mode attached to the frame, converted to a child back carrier by detaching and reconfiguring the harness, or positioned at different orientations using the rotating hub mechanism. This multi-functionality eliminates the need for separate devices.
2Device complexity
If a stroller is designed without height adjustment, then the structure is simpler, but it cannot function adequately as a high chair
Solution Approach 1:
The side bars incorporate telescopic sections that allow dynamic adjustment of the frame height. When extended, the frame reaches sufficient height for high chair functionality; when retracted, the device maintains a compact form. This dynamic adjustment enables the structure to adapt between simple stroller mode and elevated high chair mode.
3Ease of operation
If conventional child carrying devices are made collapsible, then they are easier to store, but they remain large and bulky making travel impractical
Solution Approach 1:
The device separates into a compact stroller frame and a detachable seat unit. The frame can be folded to a small size, and the seat unit can be independently configured as a child back carrier, allowing both components to be packed efficiently for travel while maintaining full functionality.
4Adaptability or versatility
If a device is designed to convert between stroller and child back carrier, then it reduces the number of devices needed, but the reconfiguration process becomes complex and time-consuming
Solution Approach 1:
The harness system is pre-configured with quick-release mechanisms and attachment points that allow rapid conversion between stroller and child back carrier modes. The rotating hub and link arms are pre-positioned to facilitate smooth transitions, reducing the time and complexity of reconfiguration.

AI summary
A child carrying device comprising a frame mounted on a set of wheels or castors to enable the device to be manually conveyed thereon, and a seat mounted on said frame, said device including adjustment means for selectively reconfiguring the device such that it is operable as any one of a stroller, a child back carrier and a high chair.
