Ceiling Truss Corner Bracket for Thin Profile Load Transfer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing ceiling trusses in drywall construction are unable to effectively bear significant loads due to narrow, thin support profiles made of sheet metal, and existing solutions are cumbersome or have low load-bearing capacity.
Innovation Solution
A ceiling truss corner bracket with a bearing area, edge region, and clamping/hook sections that form a single unit with the truss body, providing enhanced load distribution and stability, allowing for easy installation and manufacturing with minimal cuts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If support profiles are made narrow and thin to reduce material usage, then manufacturing cost and material consumption decrease, but load-bearing capacity deteriorates
Solution Approach 1:
The support profile is segmented into a main body and an integrated bracket portion, where the bracket extends perpendicularly to distribute loads over a wider area of the plasterboard, thereby maintaining load-bearing capacity while keeping the main support profile thin and narrow for material efficiency
Solution Approach 2:
The bracket extends in a direction perpendicular to the main support profile, utilizing another spatial dimension to increase the load distribution area without increasing the cross-sectional dimensions of the support profile itself, thus maintaining material efficiency while improving load-bearing capacity
2Device complexity
If loads are transferred directly through support profiles to the ceiling, then the structure remains simple, but the load-bearing capacity is insufficient due to concentrated forces
Solution Approach 1:
The force transfer path is segmented into two distinct functions: the support profile carries the load from the plasterboard, and the integrated bracket distributes this load over a wider area of the ceiling, preventing force concentration while maintaining structural simplicity
Solution Approach 2:
The bracket is merged with the support profile as an integral component, combining the load-carrying function of the support profile with the load-distributing function of the bracket into a single unified structure, thereby maintaining structural simplicity while improving load-bearing capacity
3Strength
If makeshift solutions like wooden boards between studs are used to transfer loads, then load-bearing capacity improves, but ease of operation and installation deteriorates
Solution Approach 1:
The support profile with integrated bracket serves multiple functions: it supports the plasterboard, transfers loads, and distributes forces to the ceiling, replacing the need for separate makeshift solutions like wooden boards and providing a universal solution for all load transfer requirements
Solution Approach 2:
The bracket is designed to be self-installing by simply hooking onto the support profile, eliminating the need for additional fasteners or complex assembly steps required by makeshift solutions, thereby maintaining ease of installation while providing adequate load-bearing capacity
