Luggage with Integrated Trolley Handle and Central Compartment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional luggage designs fail to optimize space and compartment accessibility, and lack effective trolley handles for maneuverability.
Innovation Solution
A luggage design featuring multiple compartments with integrated trolley handles, flexible lid connections, and a central compartment accessible from both sides, along with a telescopic handle structure for easy maneuverability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If multiple compartments are added to increase storage capacity, then the volume and storage efficiency are improved, but the device complexity and difficulty of accessing compartments increase
Solution Approach 1:
The luggage is divided into multiple independent compartments (first compartment, second compartment, central compartment) that can be accessed separately. Each compartment has its own lid portion and opening, allowing users to access specific compartments without opening the entire luggage, thus maintaining organization while improving accessibility.
Solution Approach 2:
The patent introduces a third dimension for access by providing opening portions on opposite sides of the central compartment. This allows bidirectional access to the central compartment from both the first and second compartments, creating a multi-dimensional access structure that reduces the need to open the entire luggage.
2Ease of operation
If a trolley handle is added to improve maneuverability, then the ease of operation is improved, but the device complexity increases
Solution Approach 1:
The trolley handle is integrated with the central compartment structure, where the vertical leg portions are embedded in or protruding from the side wall portions of the central compartment. This merging of the handle with the compartment structure provides maneuverability while minimizing additional complexity.
Solution Approach 2:
The central compartment serves multiple functions: it provides storage space and simultaneously houses the trolley handle mechanism. The side wall portions of the central compartment serve both as structural elements and as mounting points for the handle, reducing the need for separate components.
3Ease of operation
If the lid portions are flexibly connected to allow independent opening, then the ease of operation is improved, but the reliability of the closed structure decreases
Solution Approach 1:
The lid portions are divided into separate, independently operable units (first lid portion, second lid portion, central compartment lid) that can be opened independently. Each lid is connected through hinges and fastening openers, allowing selective access to different compartments while maintaining the closed integrity of the remaining compartments.
Solution Approach 2:
The lid portions are designed with flexible connections (hinges and fastening openers) that allow dynamic opening and closing operations. The hinges enable rotational movement for opening, while the fastening openers provide secure closure when needed, creating a system that transitions between rigid closed state and flexible open state based on operational requirements.

AI summary
A luggage includes first, second, central compartments and a trolly handle. The first compartment has a first lid portion provided on an outer opening portion, two side portions, a top portion, a bottom portion, and an inner opening portion defined by inner edges of the two side portions, the top portion, and the bottom portion. The second compartment has portions similar to the first compartment. The central compartment is provided between the inner opening portions of the first compartment and the second compartment. The trolly handle has two vertical leg portions and a handle portion connected to the two vertical leg portions substantially perpendicular to each of the two vertical leg portions. Each of the two vertical leg portions of the trolly handle is embedded in a corresponding side wall portion of the central compartment.
