Self-Tapping Fastening Insert for Universal Wall Panel Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fastening devices for attaching components to ceilings and walls require complex configurations and special substructure preparations, making them expensive and difficult to assemble universally.
Innovation Solution
A fastening device with a self-locking or self-tapping fixing means integrated into a one-piece plastic carrier part, featuring a recess for tool engagement and a pre-drilled receptacle for easy assembly, eliminating the need for profile channels or special substructure configurations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing fastening devices use profile channels and resilient hooking parts, then reliable attachment is achieved, but device complexity and assembly effort increase
Solution Approach 1:
The invention extracts and eliminates the profile channel from the fastening system, replacing it with a self-contained fixing part that has integrated fixing means. The resilient hooking part is replaced by a self-tapping or self-locking mechanism that does not require external profile channels, thereby simplifying the device while maintaining attachment reliability
Solution Approach 2:
The fixing means are integrated directly into the fixing part as a unified component, combining the functions of anchoring and fastening into a single element. This merging eliminates the need for separate profile channels and reduces the number of components, thereby reducing device complexity while ensuring reliable attachment
2Reliability
If existing fastening devices require profile channels in substructure, then secure fixing is achieved, but ease of manufacture and universal use decrease
Solution Approach 1:
The fixing part with integrated fixing means is designed to be universally applicable without requiring specific profile channel substructures. The self-tapping or self-locking mechanism can be used in various substrates (wood, metal, concrete) by simply providing a pre-drilled receptacle, making the fastening device universal and easy to manufacture for different applications
Solution Approach 2:
The fixing means are pre-configured in the fixing part during manufacturing, eliminating the need for on-site assembly of separate components. The self-tapping or self-locking mechanism is already integrated, so no additional assembly steps or special substructure preparations are needed, greatly easing manufacture and installation
3Reliability
If resilient hooking parts are used in fastening device, then reliable engagement is achieved, but productivity and assembly speed decrease
Solution Approach 1:
The fixing means are designed to automatically engage and lock into the pre-drilled receptacle without requiring manual manipulation of resilient hooking parts. The self-tapping or self-locking mechanism performs the engagement action itself when subjected to assembly force, eliminating the need for complex manual assembly operations and significantly improving productivity while maintaining engagement reliability
4Reliability
If special substructure preparations are required, then secure attachment is achieved, but adaptability and versatility of the fastening device decrease
Solution Approach 1:
The fixing part with integrated fixing means is designed to work with simple pre-drilled receptacles rather than requiring specialized profile channels. This design allows the same fastening device to be used in various substrates and applications (wood, metal, concrete, different panel types), greatly enhancing adaptability and versatility while maintaining secure attachment through the self-contained fixing mechanism
