Convertible Stroller Bicycle Frame Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional strollers have a short period of use due to rapid infant growth, leading to high purchase costs and environmental waste, as they are often discarded before becoming obsolete, with limited functional improvements and safety considerations.
Innovation Solution
A stroller design that can transform into a two-wheeled or three-wheeled bicycle by coupling or separating a connection frame part with a seat, allowing for adaptable use and extended lifespan, reducing waste and environmental impact.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a stroller is designed with basic functions only, then the purchase price can be reduced, but the period of use becomes even shorter and waste increases
Solution Approach 1:
The stroller is designed with a convertible structure that can transform between stroller mode and bicycle mode. The connection frame part can be detached and reconfigured to create a bicycle, allowing the product to serve multiple functions throughout the child's growth, thereby extending its useful life without significantly increasing manufacturing complexity
2Ease of operation
If a stroller is designed to be foldable for convenient storage, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The stroller is divided into separable modules: a main body part and a connection frame part. The connection frame part can be detached from the main body and reused when transforming into a bicycle, reducing the complexity of folding mechanisms while maintaining storage convenience through modular design
