Recessed Luggage Attachment Member for Secure Bag Coupling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current luggage articles lack efficient and cost-effective mechanisms for selectively attaching a second luggage article, especially on hard side luggage, due to the difficulty and expense of adding external features, and existing solutions often add unnecessary weight, complexity, and are prone to loss or misplacement.
Innovation Solution
A luggage case with a recess and attachment member, such as a hook-like structure, integrated into the main body, allowing for the secure attachment of a second luggage article without increasing weight or complexity, and featuring a retractable tow handle and lock mechanism for added security and protection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If removable attachment members (belts or straps) are added to enable selective attachment of a second luggage article, then the ability to attach multiple luggage articles is improved, but the weight and complexity of the luggage article increases
Solution Approach 1:
The attachment member is nested within a recess formed in the luggage article shell. The recess receives and conceals the attachment member, allowing it to be integrated into the luggage structure without adding external complexity or protruding elements. This nesting approach enables the attachment function while maintaining a clean, simple exterior design.
Solution Approach 2:
The attachment member is extracted from traditional external belt or strap forms and reimagined as an integrated structural element within the luggage shell. By taking the attachment function out of separate removable components and embedding it into the luggage structure itself, the design eliminates the need for separate belts or straps while maintaining the attachment capability.
2Adaptability or versatility
If external attachment features are added to hard side luggage articles, then the ability to attach multiple luggage articles is improved, but the manufacturing difficulty and expense increases
Solution Approach 1:
The recess is formed as an integrated feature within the hard side shell structure, allowing the attachment member to be nested within the existing luggage architecture. This approach avoids the need to add external protruding features to the shell, thereby maintaining ease of manufacture while enabling the attachment function.
Solution Approach 2:
The recess and attachment member are merged into a single integrated structure that is formed as part of the luggage shell manufacturing process. By combining the attachment feature with the shell structure itself rather than adding it as a separate external component, the manufacturing process remains simple and cost-effective.
3Adaptability or versatility
If removable attachment members are used, then the ability to selectively attach luggage articles is improved, but the reliability of the attachment connection deteriorates due to loss or misplacement
Solution Approach 1:
The attachment member is merged with the luggage shell structure through the recess, creating a permanent, non-removable connection point. This integration ensures that the attachment member cannot be lost or misplaced, while still allowing selective attachment of other luggage articles through the fixed attachment interface.
Solution Approach 2:
The attachment member is nested within the recess and secured in place, preventing it from being detached or lost. This nesting configuration maintains the attachment capability while ensuring the attachment member remains reliably positioned on the luggage article throughout use.

AI summary
In one embodiment, a luggage case is disclosed. The luggage case includes a main body including a lid shell and a base shell. The lid shell and the base shell are hingedly coupled to one another and selectively closable by a closure mechanism. The luggage case further includes a primary recess, the primary recess defining a bottom wall. A secondary recess is formed in the bottom wall of the primary recess and an attachment member is positioned in the secondary recess.
