Snap-Fit Parallel Connection for Structural Profile Assemblies
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing parallel connections in construction assemblies using structural profiles weaken the material due to screw holes, damaging protective layers and creating load nodes that reduce durability.
Innovation Solution
Elastically deformable anchoring structures with snap connections that form a form-fitting connection along the entire length of structural profile sections, eliminating the need for boreholes and maintaining corrosion-protective coatings, and incorporating spreading spring assemblies with locking mechanisms to enhance resilience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If screw connections are used to join structural profile sections, then parallel connections are achieved, but the protective layers are damaged and load nodes are created that weaken the material
Solution Approach 1:
The invention extracts the harmful element (screw holes penetrating the profile) by using snap connections that engage with the profile surface without creating through-holes. The anchoring structures are inserted into grooves cut from the surface, eliminating the need for boreholes that damage protective layers and create weak points in the material.
Solution Approach 2:
The invention applies local quality by creating grooves only where needed for connection purposes rather than drilling holes through the entire profile. The grooves are surface-level features that provide anchoring for snap connections while preserving the integrity and protective coatings of the profile material in surrounding areas.
2Reliability
If snap connections are used instead of screw connections, then corrosion-protective coatings remain intact and full profile cross-sections are maintained, but the connection mechanism becomes more complex
Solution Approach 1:
The connection mechanism is segmented into modular components: structural profiles with integrated grooves, separate anchoring structures with elastic deformable areas, and snap-fit engagement features. This segmentation allows each component to be optimized independently while maintaining overall simplicity and reliability of the connection 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
Provides durable and resilient parallel connections between structural profiles without material weakening, maintaining full cross-sections and preventing disengagement under load, thus enhancing structural integrity.
Implementation Method 1
the anchoring structures are elastically deformable areas with which the parallel connection and the structural profile sections cut to length interact in a form-fitting manner via snap connections
Implementation Method 2
the parallel connection is designed as a spreading spring assembly, the spring legs of which, arranged in pairs, have locking lugs at their free ends

AI summary
In an assembly comprising a structural profile and a parallel connection (3), the structural profile has an undercut longitudinal groove (12), and the parallel connection (3) has anchoring structures that can be fixed in the longitudinal groove (12) of the structural profile. The anchoring structures are elastically deformable areas with which the parallel connection (3) and structural profile sections (12, 13) cut from the structural profile interact in snap connections. The parallel connection (3) is designed as a spring-loaded assembly, the spring legs (4, 5; 6, 7) of which are arranged in pairs and have locking lugs (8, 9, 10, 11) formed at their free ends.
