Suspended Ceiling Hanger with Removable Bracing Elements
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hanger systems for suspended ceilings are costly, overly rigid, and heavy, particularly when the distance between the ceiling slab and the suspended structure exceeds 30 cm, leading to deformation risks and increased weight, which is inefficient for structures like medical devices and standard housing or office constructions.
Innovation Solution
A suspension device featuring a rod with removably fixed bracing means composed of two rigid elements with nested edges forming a sleeve to enhance stability and prevent deformation, allowing for adjustable rigidity and ease of installation, along with a veil to limit air current propagation and fire spread.

Engineering Contradiction Analysis
1Stability of the object's composition
If traditional threaded rods are used for hangers, then the structure is simple and easy to install, but the rigidity is insufficient when the distance between ceiling slab and suspended structure exceeds 30 cm, leading to deformation risks
Solution Approach 1:
The hanger is divided into multiple functional segments: a rod element for suspension, bracing elements for lateral stability, and a bearing surface for load distribution. This segmentation allows each component to be optimized independently - the rod provides tensile strength while the bracing elements provide lateral rigidity, resolving the contradiction between simplicity and rigidity.
Solution Approach 2:
The invention transitions from a one-dimensional rod to a three-dimensional structure by adding bracing elements that extend laterally. The bracing elements create a spatial framework that resists deformation in multiple directions, adding dimensional stability without significantly increasing installation complexity.
2Strength
If profiles with large cross section are used to increase rigidity for heavy devices, then the rigidity is sufficient to support heavy medical devices, but the weight of the false ceiling increases significantly
Solution Approach 1:
The hanger combines different material properties in a composite structure: the rod element provides tensile strength to support vertical loads, while the bracing elements provide lateral rigidity. This composite approach achieves high load-bearing capacity without requiring a single heavy-profile solution, thereby reducing the overall weight of the false ceiling structure.
Solution Approach 2:
By segmenting the load-bearing function across multiple lightweight elements (rod + bracing elements) rather than using a single heavy profile, the structure achieves equivalent strength with reduced weight. Each segment is optimized for its specific function, creating an efficient lightweight structure.
3Stability of the object's composition
If oversized hangers with large cross section profiles are used, then the rigidity is sufficient for heavy devices, but the cost of manufacture and installation increases
Solution Approach 1:
The bracing elements are designed as simple, inexpensive components that can be easily manufactured and installed. Rather than using expensive oversized profiles, the invention employs multiple simpler elements that collectively provide the necessary rigidity at lower cost, treating the bracing elements as cost-effective structural additions.
Solution Approach 2:
Segmenting the rigidity function across multiple simple bracing elements rather than using a single complex oversized profile reduces manufacturing costs. Each element can be manufactured independently using simpler processes, and the modular nature allows for efficient assembly and installation.
4Stability of the object's composition
If the hanger structure is made heavier to prevent deformation at greater distances, then the stability improves, but the ease of installation and removability decreases
Solution Approach 1:
The hanger design allows for dynamic adjustment and easy assembly/disassembly despite providing stable support. The bracing elements can be readily installed and removed, enabling flexibility in installation while maintaining structural stability during service. This dynamic approach resolves the contradiction between stability and ease of operation.
Solution Approach 2:
By segmenting the hanger into modular components (rod, bracing elements, bearing surface), the structure achieves stability through proper geometric arrangement rather than heavy materials. The modular segments are lightweight and easy to handle, facilitating simple installation and removal while maintaining structural integrity.
