Fastening Clip with Dual Retaining Elements for Planar Element Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fastening clips for planar elements are cumbersome to install and prone to falling out of the planar element before it is mounted on a component, and they can also fall out during removal, leading to inefficient assembly and potential instability.
Innovation Solution
A fastening clip system with a flexible holding element that exerts contact pressure on both sides of the planar element, allowing secure pre-assembly and improved stability through a dual holding mechanism, which includes a first holding element engaging in an opening and a second holding element providing additional retention, enabling easier handling and secure attachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a fastening clip is inserted into the flat element before the flat element has been brought into contact with the building component, then the fastening clip can be pre-assembled on the flat element, but the fastening clip can easily fall out of the flat element
Solution Approach 1:
The fastening clip is divided into two separate retaining elements: a first retaining element that engages with the building component through an opening, and a second retaining element that engages with the flat element through a recess. This segmentation allows each element to perform its specific function independently, preventing the fastening clip from falling out during pre-assembly while maintaining reliability during final assembly.
Solution Approach 2:
The second retaining element is designed to engage with the flat element before the flat element is mounted to the building component. This preliminary action secures the fastening clip to the flat element during handling and transport, enabling pre-assembly operations without the risk of the fastening clip falling out.
2Device complexity
If a fastening clip uses a single retaining element engaging through a recess into an opening, then the structure is simple, but the fastening clip is cumbersome to install and prone to falling out
Solution Approach 1:
The single retaining element is segmented into two distinct retaining elements with different functions. The first retaining element interacts with the building component, while the second retaining element interacts with the flat element. This segmentation simplifies the installation process by providing dedicated engagement points for each component, eliminating the cumbersome handling issues of single-element designs.
Solution Approach 2:
The second retaining element acts as an intermediary that facilitates the connection between the fastening clip and the flat element during pre-assembly. It provides a stable engagement point that simplifies handling and installation, while the first retaining element completes the connection to the building component.
3Strength
If a fastening clip relies on force-fit connection between the retaining element and the hole wall, then the connection is secure when mounted, but the fastening clip can fall out during removal
Solution Approach 1:
The force-fit connection is segmented into two separate engagement mechanisms: the first retaining element provides the force-fit connection with the building component for secure attachment, while the second retaining element provides engagement with the flat element that prevents falling out during removal. Each segment maintains its specific function throughout the attachment and removal cycles.
Solution Approach 2:
The second retaining element engages with the flat element in advance, creating a preliminary secure connection that prevents the fastening clip from falling out during removal operations. This preliminary engagement ensures reliability throughout the entire service life of the 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 system allows for easier pre-assembly and secure attachment of the fastening clip to the planar element, reducing assembly time and improving stability by ensuring the clip remains in place during installation and removal, with enhanced retention forces and reduced risk of falling out.
Implementation Method 1
The fastening clip has a first, flexible retaining element connected to the contact section and configured such that, after the planar element has been fixed to the component, it engages through the recess of the planar element into the opening
Implementation Method 2
the fastening clamp has a second, elastic retaining element which is connected to the contact section and is designed such that it engages the flat element through the recess of the flat element on a second side of the flat element, which faces the bore, in such a way that the fastening clamp exerts a clamping force on the second side of the flat element
Implementation Method 3
when the contact plane rests on the first side of the planar element
