Spring-Loaded Fastening System for Luggage Containers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems for attaching containers to luggage carriers are cumbersome, with protruding fastening elements that make the containers heavier and less smooth, and require complex unlocking mechanisms, making attachment and removal inconvenient.
Innovation Solution
A compact locking system with a spring-loaded fastening element and receiving device that allows for easy attachment and removal, featuring a cylindrical fastening element with a guide rail and a self-locking mechanism that can be unlocked manually, keeping the system flat and lightweight.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If large stable hooks or hooks with large deflections are used to attach containers to the carrier, then the attachment strength is improved, but the device complexity and weight increase
Solution Approach 1:
Instead of using large hooks on the container to engage with the carrier, the patent inverts the approach by using small fastening elements on the carrier that engage with receiving elements on the container. This reversal allows the container structure to remain simple and smooth while the mounting device on the carrier provides the necessary strength and complexity.
Solution Approach 2:
The attachment system is divided into separate functional components: fastening elements mounted on the carrier and receiving elements on the container. This segmentation allows each component to be optimized independently - the fastening elements can be strong and stable while the container structure remains simple.
2Ease of operation
If multiple attachment points with wide guide grooves are used on the carrier, then the ease of insertion is improved, but the device complexity and weight increase
Solution Approach 1:
Instead of making the entire mounting device complex with wide guide grooves across the whole carrier surface, the patent applies localized receiving elements with integrated guide features only where needed. This provides sufficient guidance for insertion while keeping the overall device simple and lightweight.
3Adaptability or versatility
If protruding fastening elements are attached to the container, then the attachment functionality is improved, but the surface smoothness and weight are worsened
Solution Approach 1:
The patent reverses which component has the fastening elements and which has the receiving elements. The carrier gets the active fastening elements while the container has passive receiving elements that can be smoothly integrated into its structure, eliminating protruding elements on the container surface.
Solution Approach 2:
The complex fastening mechanism is extracted from the container and placed on the carrier instead. This allows the container to maintain a smooth, simple surface while the carrier bears the complexity of the attachment system.
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
Enables easy and secure attachment and removal of containers without prior unlocking, maintaining a smooth surface and reducing weight, with the ability to be integrated into the container design for a seamless and convenient handling experience.
Implementation Method 1
the receiving element is provided with an unlocking or contact area on its inlet side via a spring-loaded means and that Fastening element can be locked in the receiving element by means of the spring-loaded means
