Elastic Strap with Tongue and Groove for Luggage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for attaching additional luggage to rolling suitcases fail to securely prevent side-to-side movement during sharp turns or sudden movements, and often restrict the size and orientation of the additional parcel.
Innovation Solution
A hook and loop fastening mechanism-based attachment device that wraps around the additional parcel and can be slid over the retractable handle of a rolling suitcase, providing secure attachment in both vertical and horizontal orientations, with optional storage pockets and made from stretchable materials like neoprene or elastic.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If straps, buttons, clips, or buckles are used to attach additional luggage, then the attachment mechanism provides basic securing capability, but the additional parcel can still move laterally during sharp turns or sudden movements
Solution Approach 1:
The attachment device is divided into multiple functional segments: a first strap that attaches to the rolling suitcase, a second strap that attaches to the additional parcel, and a connecting mechanism with tongue and groove elements. This segmentation allows each component to perform its specific function independently, providing secure attachment while preventing lateral movement through the interlocking tongue and groove structure.
Solution Approach 2:
The tongue and groove connecting mechanism acts as an intermediary between the first and second straps. The tongue element on the first strap inserts into the groove element on the second strap, creating a rigid connection that prevents lateral movement while maintaining ease of attachment and detachment. This intermediary structure transforms flexible straps into a stable, movement-preventing assembly.
2Adaptability or versatility
If Velcro or hook and loop fastening means are used to surround individual parcels, then attachment is achieved, but the mechanism lacks support for sudden movements and requires complex buckle attachments
Solution Approach 1:
The invention merges the advantages of hook and loop fastening (flexibility, adaptability) with the structural stability of tongue and groove interlocking. The hook and loop straps provide flexible attachment to surround parcels of various sizes, while the integrated tongue and groove connecting elements add structural support to prevent lateral movement. This combination eliminates the need for separate buckle mechanisms while maintaining both adaptability and stability.
3Reliability
If clasp mechanisms with tongue and slot means are used, then secure attachment is achieved, but the additional parcel is not securely seated and can slide during sudden movements
Solution Approach 1:
The invention uses flexible straps made of durable material that can conform to the shape of the additional parcel while maintaining tensile strength. The flexible nature of the straps allows them to wrap securely around the parcel, while the rigid tongue and groove connecting elements provide structural support to prevent sliding during sudden movements. This combination of flexible attachment and rigid connection resolves the stability issue.
4Ease of operation
If hooks, loops, and straps are used to attach auxiliary bag, then attachment is achieved, but the bag hangs from front end and can easily slide during sharp turns
Solution Approach 1:
The invention transitions from single-point or single-axis attachment to multi-point, multi-dimensional attachment. The first strap attaches to the rolling suitcase at one location, the second strap attaches to the additional parcel at another location, and the tongue and groove connector provides a third point of connection. This multi-dimensional attachment geometry distributes forces and prevents side-to-side sliding that occurs with simple front-end hanging attachment.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The device securely hugs the additional parcel to the rolling suitcase, preventing sliding or swinging, and allows for versatile attachment of various bag sizes and shapes, ensuring ease of use and universal compatibility.
Implementation Method 1
The device includes a hook and loop fastening mechanism that secures the device around an additional parcel
Implementation Method 2
made from stretchable materials like neoprene or elastic

AI summary
A strap mechanism for attaching an additional parcel to a rolling suitcase is disclosed. A strip of elasticized material with a sleeve for sliding over a rolling suitcase handle is secured around the parcel using a hook and loop fastening mechanism. The strap mechanism prevents the additional parcel from twisting off or otherwise falling off of the rolling suitcase. A horizontally and vertically oriented device is presented, as well as a universal configuration. Different materials can be used for the strap mechanism including but not limited to neoprene, veltex, elastic, or medical grade elastic. Additional embodiments include the use of a pocket attached to a side of the strap which may be used for additional storage purposes.
