Modular Child Wheeled Device with Adjustable Seat and Handle
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wheeled devices for children, such as scooters, are not adequately adaptable to the size of the child and do not facilitate a stable learning process, leading to falls during use.
Innovation Solution
A set of modular elements comprising a platform, front and rear wheels, a removable handle, and a supporting body with adjustable seat mounting options, allowing the device to be configured as either a scooter or a straddled vehicle, with the handle capable of being controlled by an adult for safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a removable seat mounting is provided on a scooter, then the learning process is facilitated, but the device is not easily adaptable to the size of the child
Solution Approach 1:
The device is divided into separate modular components: a platform, a supporting body with adjustable seat, and a handle. This segmentation allows the seat and supporting body to be independently adjusted to match different child sizes while maintaining the scooter functionality, thereby resolving the contradiction between facilitating learning and adapting to various child sizes.
Solution Approach 2:
The supporting body is designed with adjustable features that allow dynamic reconfiguration. The seat can be positioned at different locations on the supporting body, and the handle can be attached at different positions on the platform, enabling the device to adapt to different child sizes and learning needs.
2Adaptability or versatility
If the handle is mounted on the front of the platform, then a conventional scooter is formed, but the device cannot be easily adapted for different child sizes
Solution Approach 1:
The platform is designed with universal mounting features that can accommodate both handle attachment and supporting body attachment. The same platform structure serves multiple functions: it can support the handle for scooter mode, support the adjustable supporting body for straddled mode, and accommodate both configurations simultaneously, thereby achieving versatility without proportionally increasing complexity.
