Adjustable Ceiling Profile for Drywall Fastening
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing drywall systems lack efficient fastening mechanisms that maximize installation flexibility and stability, particularly in transverse planes, and are unsuitable for supporting heavy loads such as fire doors or heavy windows.
Innovation Solution
A length adjustable profile apparatus with a sliding connection between a ceiling and profile, featuring a ceiling anchor and connection element that allows for secure fastening along the profile's length, providing stability in transverse planes and supporting heavy loads.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a sliding connection is made by sliding stud profiles between components of a counter profile, then the ceiling can accommodate rise and fall movements, but fastenings cannot be applied at the interaction area as this would impede the mobility of the sliding connection
Solution Approach 1:
The counter profile is divided into separate components: a sliding component that moves with the ceiling and a stationary component that provides fastening points. This segmentation allows the sliding function and fastening function to be separated spatially, resolving the contradiction between mobility and fastening capability.
Solution Approach 2:
The fastening points are positioned in a different spatial dimension relative to the sliding path. By offsetting the fastening area from the direct sliding interaction zone, the profile can maintain sliding mobility while providing adequate fastening points at alternative locations.
2Ease of manufacture
If standard stud profiles with U-shaped or C-shaped cross-section are used, then construction is cheap and simple with quick installation, but the profiles cannot support heavy loads in non-vertical directions
Solution Approach 1:
The profile system combines thin-walled sheet metal profiles with reinforced connection components and bracing elements. The composite structure maintains the simplicity of standard profile installation while adding strength through the integrated reinforcement system that supports heavy loads in transverse directions.
Solution Approach 2:
The profile system incorporates adjustable and adaptable connection mechanisms that can dynamically respond to load requirements. The sliding connection allows the structure to adapt to movement while maintaining structural integrity under various load conditions through engineered reinforcement points.
3Productivity
If fastenings are required to penetrate only a single layer of sheet metal for quick installation, then installation efficiency increases, but the fastening area is limited compared to profiles requiring multiple penetration points
Solution Approach 1:
The counter profile components are designed with multi-functional features that provide both sliding capability and multiple fastening points along their length. The extended components serve dual purposes: maintaining sliding mobility while providing numerous opportunistic fastening locations, effectively increasing the usable fastening area without compromising installation efficiency.
