Hinged Travel Case Compartments for Selective Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional travel cases lack efficient compartmentalization and access mechanisms, making it difficult to organize and access different types of items conveniently during travel.
Innovation Solution
A hard travel case with multiple compartments, featuring a main body and sub-compartments that hinge between closed and open positions, allowing for independent or unified access, and equipped with spring hinges and access doors that swing on horizontal or vertical axes for enhanced organization and accessibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional travel cases are used, then the structure is simple, but the compartmentalization and access efficiency are poor
Solution Approach 1:
The travel case is divided into a main compartment and multiple sub-compartments, each with independent access doors. The sub-compartments can be opened independently from the main compartment, allowing selective access to different items without opening the entire case. This segmentation enables efficient organization of different types of items (e.g., liquids, electronics, clothes) with dedicated access points for each category.
2Productivity
If multiple compartments are added for better organization, then the storage efficiency improves, but the device complexity increases
Solution Approach 1:
Multiple hinge mechanisms (main compartment hinges and sub-compartment hinges) are integrated into a unified hinge system that shares common mounting points and structural support. The hinge assembly combines the functionality of opening both the main compartment and sub-compartments through a coordinated mechanism, reducing the number of separate hinge components needed and simplifying the overall structure while maintaining multiple access points.
3Ease of operation
If sub-compartments are made accessible independently, then the access convenience improves, but the structural complexity increases
Solution Approach 1:
The sub-compartment access doors are nested within the main compartment structure. Each sub-compartment door is positioned inside or along the edges of the main compartment, allowing the sub-compartments to be accessed independently while utilizing the structural framework of the main compartment. This nesting approach enables multiple access points without requiring separate external door structures for each compartment.

AI summary
A hard travel case is described comprising a main body with a main compartment, two sub-compartments, each hinging on a first side of the main body between a closed position and open position, whereby in the closed position together the sub-compartments close the main compartment, and in the open position access is provided to the main compartment, wherein each sub-compartment comprises an access door hinging on a first side of the sub-compartment between a closed position whereby the access door closes the sub-compartment and an open position allowing access to the sub-compartment.
