Reconfigurable Luggage System with Load Transfer Arrangement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional luggage designs, such as rucksacks, face issues with stress concentration on the outer skin due to load distribution, leading to potential tears and increased weight/cost for durability. Additionally, access to items within the luggage is limited and inefficient.
Innovation Solution
A reconfigurable luggage system featuring a load carrier attached to a load transfer arrangement, which directs loads away from the outer skin, allowing the outer skin to remain unstressed. The system includes a handle for lifting and multiple handles for shoulder carrying, along with a modular design for different load carriers and configurations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the outer skin is made stronger and more durable to withstand loads and stresses, then the reliability and durability of the luggage item is improved, but the weight and cost of the luggage item increases
Solution Approach 1:
The load-bearing function is extracted from the outer skin and transferred to a dedicated load transfer arrangement. The outer skin is relieved of structural support duties and only retains its cosmetic and protective functions, allowing it to be made from lighter, less durable materials without compromising overall reliability.
Solution Approach 2:
A load transfer arrangement acts as an intermediary component between the load carrier and the outer skin. This mediator transfers loads away from the outer skin to dedicated structural elements, preventing stress concentration and allowing the outer skin to be lighter while maintaining durability through the intermediary's load management.
2Ease of operation
If items are stowed in numerous pockets and storage compartments, then the organization and accessibility of items is improved, but the complexity of the luggage structure increases
Solution Approach 1:
The storage system is segmented into multiple independent pockets and compartments that can be individually accessed. The outer skin is divided into separate panels that can be independently manipulated, allowing users to access specific storage areas without unpacking the entire luggage, thus improving ease of operation while maintaining manageable complexity through modular design.

AI summary
A luggage system comprising an outer skin having a plurality of skin panels, a load transfer arrangement, a handle attached to the load transfer arrangement for lifting the luggage system, and a load carrier. The load carrier is attached to the load transfer arrangement. The outer skin is reconfigurable between a first configuration in which the skin panels are releasably connected to one another to wrap around the load carrier, and a second configuration in which the skin panels are unfurled to expose the load carrier.
