Crossed Profile Connection Device for False Ceiling Reinforcement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing construction methods for false ceilings require cumbersome and costly reinforcement of load-bearing structures, particularly when adding additional spacers, due to the lack of efficient removable connection means between profiles, leading to material waste and labor-intensive securing processes.
Innovation Solution
A device allowing for quick, easy, and reliable removable connection of two profiles at right angles, enabling additional spacers to be added to the original structure without additional tools, using V-shaped notches and L-shaped support elements to securely engage profiles without extra securing means.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If additional primary profiles are added to reinforce the supporting structure, then the structural strength is improved, but the material cost increases due to using oversized profiles and the labor time increases due to fixing profiles and spacers separately
Solution Approach 1:
The invention merges the connection of two coplanar profiles and a perpendicular profile into a single integrated device. The device simultaneously connects the first spacer and second spacer in the same plane while also connecting the vertical profile perpendicular to that plane, eliminating the need for separate connection operations and reducing overall complexity.
Solution Approach 2:
The connection device performs multiple functions: it connects two coplanar profiles (first and second spacers) and simultaneously connects a third profile perpendicular to that plane (vertical profile). This multi-functional device replaces what would otherwise require multiple separate connection operations, reducing labor time and simplifying the reinforcement process.
2Reliability
If traditional securing means are used to connect spacers to primary profiles, then the connection is reliable, but the installation time increases and the process becomes more labor-intensive
Solution Approach 1:
The device combines multiple connection functions into a single integrated structure that simultaneously secures two coplanar spacers and one perpendicular profile. This merging of connection operations into one device significantly accelerates installation while maintaining reliable connections through its integrated design with multiple engagement points.
Solution Approach 2:
The connection device is designed with pre-formed geometric features (V-shaped notches, L-shaped support elements) that are prepared in advance to receive and secure the profiles. These preliminary structural arrangements enable quick alignment and secure connection without requiring complex on-site assembly operations, thereby increasing installation speed while ensuring reliable connections.
3Adaptability or versatility
If removable connection means are implemented, then the adaptability and ease of modification are improved, but the connection strength may be reduced compared to permanent connections
Solution Approach 1:
The connection device is designed as a segmented, modular structure with distinct geometric features (V-shaped notches, L-shaped support elements, tabs) that can be independently engaged with different profiles. This segmentation allows the device to be easily removed and repositioned while maintaining strong connections during use, as each segment independently contributes to the overall connection strength.
Solution Approach 2:
The device employs asymmetric geometric features such as V-shaped notches with specific orientations and L-shaped support elements with defined concavities. These asymmetric features provide strong mechanical engagement in the installed position while allowing for controlled removal when needed, balancing connection strength with removability and adaptability.
