Installation frame for ventilation components in a ceiling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mounting frames for ventilation components in ceilings require drilling or radial cutting into the ceiling, which damages the surface and is aesthetically unappealing, and also increases installation time.
Innovation Solution
A mounting frame design featuring two tubular elements with radially projecting collars, one with an internal thread and the other with an external thread, allowing installation from the visible side without drilling, and a tapered configuration to accommodate hoses or connecting elements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If visible screws are used to fasten the mounting frame to the ceiling, then the installation is secure, but the visual appearance is compromised
Solution Approach 1:
The harmful visible screws are extracted/removed from the visible side of the installation. The fastening mechanism is relocated to the back side of the ceiling, where screws fasten the first tubular element to the ceiling structure without being visible from the front, thus maintaining visual appearance while ensuring installation security
2Ease of operation
If a self-tapping thread is used to fasten the mounting frame, then installation is simplified, but the ceiling is at risk of damage
Solution Approach 1:
The harmful radial cutting action is extracted/removed from the installation process. Instead of cutting radially around the perimeter of the ceiling, the fastening is performed axially through the hole from the back side, eliminating the risk of radial damage while maintaining installation simplicity
Solution Approach 2:
The first tubular element acts as an intermediary that distributes the fastening load over a larger area on the back side of the ceiling. This mediator structure prevents concentration of forces that could cause damage, while still allowing simple screw fastening
3Strength
If drilling or radial cutting is performed to the side of the hole, then the mounting frame can be secured, but installation time increases
Solution Approach 1:
The hole in the ceiling is prepared in advance at the correct position and size. The first tubular element is designed with pre-formed fastening features (screw holes or external threading) that allow direct fastening through the existing hole without requiring additional drilling or cutting operations during installation
Solution Approach 2:
The mounting frame is segmented into two separate tubular elements with different fastening mechanisms on opposite sides. This segmentation allows each element to be optimized for its specific function (one for secure fastening to ceiling structure, one for visible side installation) without requiring additional ceiling modifications
