Spring-Loaded Lever Adapter for Luggage Carrier Struts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing adapter systems for attaching bags or containers to luggage carriers, particularly on the upper side, face issues such as disruption of the carrier's surface when not in use, limited adaptability to different strut configurations, and insufficient stability due to aging or design flaws like Velcro straps losing holding power.
Innovation Solution
An adapter system featuring spring-loaded, rotatably mounted levers with adjustable and friction-enhanced holding elements that securely clamp onto luggage carrier struts, allowing for reversible attachment and adjustable fit to various carrier geometries, ensuring self-locking stability and easy removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a holding device is firmly connected to the luggage carrier and protrudes beyond the upper side, then the bag can be fastened securely, but the upper side of the luggage carrier cannot be fully used when the bag is not attached
Solution Approach 1:
The invention extracts the holding function from a permanent fixed structure and relocates it to a removable adapter system. The adapter with holding elements can be detached when not in use, freeing up the luggage carrier upper side for other purposes while maintaining secure fastening capability when needed.
Solution Approach 2:
The holding elements are designed to be adjustable and repositionable along the struts, allowing dynamic adaptation to different positions and configurations. This enables the system to provide secure fastening when required while allowing the carrier surface to remain fully accessible when the adapter is removed or repositioned.
2Reliability
If lateral snap hooks or spring-loaded tensioning elements are used, then the bag can be fastened to struts, but the system requires a precisely defined distance between longitudinal struts which limits adaptability to different luggage carriers
Solution Approach 1:
The adapter system is designed with holding elements that can be positioned at various locations along the struts and adjusted to accommodate different strut distances and diameters. This universal design allows the same adapter to work with multiple luggage carrier models and configurations, eliminating the need for precisely defined strut spacing.
Solution Approach 2:
The holding elements are made adjustable and repositionable, allowing the system to adapt dynamically to different strut configurations. The elements can be moved along the struts to match varying distances between longitudinal struts on different luggage carriers, providing both stability and versatility.
3Ease of operation
If Velcro straps are used for fastening, then the attachment is simple, but the straps considerably lose their holding power during use or due to aging
Solution Approach 1:
The invention replaces the friction-based Velcro fastening system with a mechanical lever-based clamping mechanism. The spring-loaded levers with friction surfaces provide positive mechanical engagement around the struts, maintaining holding power over time without the degradation issues of Velcro while still allowing easy operation through the release mechanism.
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 adapter system maintains the upper carrier surface's usability when not in use, provides high stability during attachment, and adapts to different luggage carrier configurations, ensuring secure and reliable fastening while allowing easy detachment.
Implementation Method 1
equipped with a spring-loaded and rotatably mounted lever
Implementation Method 2
the lever is made of an elastic material or at least the surface of the lever that comes into contact with the luggage carrier strut
Implementation Method 3
the lever has a surface, a protrusion or an angular element or a shell element at that end of the lever which faces away from the pivot point pivots in from below in a manner gripping over or onto the luggage carrier strut

AI summary
An adapter system for mounting or fastening bags or containers with fixing elements for engaging between struts of a luggage carrier and which can be reversibly attached on the upper side of a luggage carrier. The adapter system has at least two holding elements which engage on opposite struts of the adapter and are equipped with a spring-loaded and rotatably mounted lever, and the rotatably mounted lever has a geometry at that end of the lever which faces away from the pivot point and securely clamps the adapter system on the luggage carrier struts in a self-locking manner.
