Adjustable Suspended Ceiling Fixing Device for Acoustic Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing suspended ceiling installation systems cannot easily produce ceilings with inclined tiles or tiles on different levels, limiting acoustic correction and aesthetic options, as they lack a standardized and ready-to-use device for such configurations.
Innovation Solution
A device featuring adjustable threaded rods and customizable fixing hooks allows for independent positioning of ceiling tiles at variable heights and inclinations, enabling sound absorption and reflection adjustments by trapping sound in openings or directing it preferentially.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional flat slab fixing systems are used, then the ceiling is easy to install and maintain, but the acoustic correction capability is limited and aesthetic options are restricted
Solution Approach 1:
The fixing device incorporates adjustable threaded rods that allow the ceiling slabs to be positioned at variable heights and inclinations. The rods can be rotated to change the angle and position of the slabs, transforming the rigid fixed system into a dynamic adjustable one, thereby enabling acoustic correction through inclined or multi-level slab arrangements
Solution Approach 2:
The fixing system is divided into independent modular components: separate threaded rods, fixing hooks, and slab mounting plates. Each component can be independently adjusted and positioned, allowing individual slabs to be set at different angles and heights to create voluminous ceiling configurations for optimized acoustic correction
2Adaptability or versatility
If wired hanging systems with individually adjusted hooks are used, then acoustic correction through inclined tiles is achieved, but the installation process is time-consuming and not standardized
Solution Approach 1:
The fixing device is designed as a universal standardized system where the same threaded rod and fixing hook components can be used for all ceiling slabs regardless of the desired final position. Each component serves multiple functions: the threaded rod provides both suspension and angular adjustment, while the fixing hook accommodates various slab orientations, eliminating the need for custom-wired systems
Solution Approach 2:
The system enables quick adjustment of installation parameters (height, inclination angle, horizontal position) by simply rotating the threaded rods to different positions. This parameter-based adjustment mechanism allows standardized components to achieve variable configurations, significantly speeding up installation compared to custom-wired systems
3Adaptability or versatility
If ceiling tiles are fixed in fixed positions, then the structure is stable, but the ability to transform between flat and three-dimensional configurations is lost
Solution Approach 1:
The threaded rod fixation system allows the ceiling structure to transition between static stable states at different configurations. The rods can be adjusted to lock slabs in fixed positions for stability, or repositioned to transform the ceiling from flat to three-dimensional voluminous forms, providing both stability and adaptability
Solution Approach 2:
Each ceiling slab is independently mounted on its own threaded rod and fixing hooks, creating modular segments. This segmentation allows individual slabs to be positioned at different angles and heights while maintaining overall structural stability, enabling transformation between flat and three-dimensional configurations without compromising the entire ceiling structure
