Convertible Carrier Collapsible Cart with Universal Receiver
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current collapsible carriers for child car seats are limited by their proprietary designs and require extensive storage space, failing to provide a universal receiver and compact configuration suitable for both stroller and utility cart use.
Innovation Solution
A collapsible cart with a modular frame design that includes an upright frame, base frame, receiver frame, and ground transport wheels, allowing for universal reception of child car seats and easy reconfiguration between stroller and utility cart modes, featuring a latch system for handle adjustment and quick-release mechanisms for compact storage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If a stroller is designed to be collapsible, then storage space requirement is reduced, but it still requires extensive trunk space and cannot be compactly stored
Solution Approach 1:
The stroller frame is designed so that the seat unit nests within the frame structure when collapsed. The seat backrest folds inward and the seat base tucks into the frame, creating a compact nested configuration that significantly reduces the overall volume occupied by the stroller in its collapsed state.
Solution Approach 2:
The stroller is divided into separable components including the frame, seat unit, and receiver assembly. These segments can be independently folded and nested within each other, allowing the entire stroller to collapse into a compact configuration that fits in smaller vehicle trunks rather than requiring extensive storage space.
2Reliability
If a stroller accepts proprietary car seats, then compatibility with specific models is ensured, but universality across different car seat models is limited
Solution Approach 1:
The receiver assembly is designed with universal compatibility features including adjustable positioning mechanisms and adaptable connection interfaces. The receiver can accommodate multiple car seat models from different manufacturers through its flexible mounting system, allowing the stroller to function with various car seats rather than being limited to proprietary models.
Solution Approach 2:
The receiver assembly incorporates dynamic adjustment capabilities that allow it to adapt its position and configuration based on the specific car seat being attached. This dynamic adaptability enables reliable connection across different car seat types while maintaining secure attachment, resolving the contradiction between universal compatibility and reliable connection.
3Adaptability or versatility
If a stroller is designed for dual use as stroller and utility cart, then versatility is improved, but device complexity increases
Solution Approach 1:
The stroller is segmented into modular components including the frame, seat unit, and receiver assembly that can be independently positioned. By segmenting the structure, the stroller enables simple reconfiguration between stroller and utility cart modes through straightforward component relocation rather than complex mechanical transformations.
Solution Approach 2:
The stroller design allows inversion of its primary function - the receiver assembly and seat unit can be repositioned from the traditional stroller configuration to create a utility cart configuration. This inversion approach simplifies the transition mechanism by using the existing modular components in alternative arrangements rather than requiring additional complex conversion mechanisms.
