Integrated Luggage Cart System with Hinged Shell
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Travelers face challenges in transporting multiple luggage items efficiently and securely, as renting baggage carts is costly, and strapping luggage together fails to properly contain and secure items, leading to instability.
Innovation Solution
An integrated luggage cart system (ILCS) with a built-in conveyor cart assembly, including a frame, wheel assembly, and hinge mechanism, allowing multiple luggage items to be securely transported without additional carts, and accommodating various travel accessories.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If travelers rent a baggage cart or use airport porter services, then multiple luggage items can be transported securely, but the cost increases significantly
Solution Approach 1:
The patent combines a conventional luggage with a conveyor cart system into a single integrated unit. The cart is mechanically attached to the luggage through a frame and hinge mechanism, allowing the luggage itself to serve as the cart base, eliminating the need for separate rental services
Solution Approach 2:
The luggage is designed to perform multiple functions: it serves as both the container for personal items and as the base for a conveyor cart system. The integrated design allows a single item to fulfill both luggage and cart functions, reducing dependency on external services
2Object-affected harmful factors
If travelers strap luggage together using luggage straps or bungees, then no additional cost is incurred, but the ability to properly contain and secure multiple articles of luggage is lost
Solution Approach 1:
The patent merges the luggage and cart into a single stable unit where the cart frame provides structural support and the hinge mechanism ensures secure connection. This integrated structure offers superior stability compared to loose straps, preventing items from toppling over during transport
3Reliability
If a built-in conveyor cart assembly is integrated into the luggage, then secure transportation of multiple items is achieved, but the device complexity increases
Solution Approach 1:
The conveyor cart system is nested within the luggage structure. The cart frame and wheel assembly are housed within or attached to the luggage body, allowing the complex system to be compact when not in use and easily deployed when needed
Solution Approach 2:
The integrated system is divided into distinct functional modules: the luggage component, the cart frame, the wheel assembly, and the hinge mechanism. This segmentation allows for easier manufacturing, assembly, and maintenance while maintaining overall system functionality
4Object-affected harmful factors
If multiple luggage items are transported without proper containment, then cost is reduced, but the items can topple over and become unstable
Solution Approach 1:
By combining the luggage and cart into a single stable platform, the invention provides a unified base that prevents individual items from toppling. The integrated design ensures that all items remain securely positioned during transport without requiring additional containment measures

AI summary
An integrated luggage apparatus includes: a rear shell, a front shell hingedly attached to the rear shell by a hinged attachment, a cart base fixedly attached to a bottom of the rear shell; a cart frame pivotally attached to the cart base; at least one wheel assembly; and a handle assembly. When the front shell is rotated about a hinged attachment and comes into contact with the rear shell, both the front shell and the rear shell define a space for a person to pack personal items, such as clothing.
