Smoke Detector Mounting on Stretch Ceilings
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for installing smoke detectors on already installed stretch ceilings are time-consuming and require disassembly of the ceiling canvas, posing a risk of damage and inefficiency.
Innovation Solution
A method involving partial dismantling of the canvas to mark the location, fixing an annular reinforcing washer, cutting the fabric to create a passage opening, and using an adjustable intermediate fixing structure to secure the smoke detector without full disassembly, allowing for secure and fast installation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the canvas is fully disassembled to install the smoke detector structure, then the detector can be securely fixed to the ceiling, but the installation becomes time-consuming and the canvas is at risk of damage
Solution Approach 1:
The patent applies preliminary action by pre-assembling the fixing structure (mounting plate and detector) on the ceiling before stretching the canvas. This allows the structure to be securely fixed to the ceiling in advance, eliminating the need for full canvas disassembly during detector installation. The canvas is then stretched around the pre-installed structure, securing it in place while avoiding time-consuming reassembly operations.
Solution Approach 2:
The patent segments the installation process into distinct phases: first installing the mounting plate and detector structure on the ceiling, then stretching the canvas around it. This segmentation allows the fixing structure to be independently secured to the ceiling without requiring complete canvas removal, thereby reducing installation time while maintaining secure fixation.
2Manufacturing precision
If the canvas is disassembled to access the ceiling for structure installation, then the fixing structure can be properly positioned, but the complexity and difficulty of installation increase
Solution Approach 1:
The patent applies preliminary action by pre-positioning the mounting plate on the ceiling at the desired location before canvas installation. This ensures precise positioning of the fixing structure without requiring complex canvas manipulation or trial-and-error adjustments after the canvas is stretched. The mounting plate is secured to the ceiling directly, establishing accurate positioning in advance.
3Ease of operation
If the canvas is cut to access the fixing structure, then the smoke detector can be installed, but the canvas integrity is compromised and repair becomes necessary
Solution Approach 1:
The patent applies preliminary action by installing the mounting plate and detector structure on the ceiling before the canvas is stretched. This eliminates the need to cut the canvas to access the fixing structure, as the structure is already in place and the canvas simply needs to be stretched around it. The canvas integrity is fully preserved while maintaining ease of operation.
4Productivity
If no pre-provided structures are installed before canvas stretching, then the stretch ceiling can be installed completely, but subsequent smoke detector installation requires canvas disassembly
Solution Approach 1:
The patent applies preliminary action by installing the mounting plate and detector structure on the ceiling before the canvas is stretched. This forward-planning approach eliminates the need for subsequent canvas disassembly operations, thereby improving overall installation efficiency and making the detector installation process straightforward. The structure is already in position, requiring only canvas stretching around it.

AI summary
The invention relates to a method of installing a technical device, such as a [missing word], on a stretch ceiling already installed, comprising a flexible fabric stretched below a ceiling of a room, the stretched flexible fabric delimiting with the ceiling a residual space, characterized in that it comprises the steps of determining the location of the technical device to be installed on the flexible fabric, forming a passage opening in the fabric allowing passage to the residual space at the level of the determined location, installing an intermediate fixing structure in the residual space through the passage opening, the intermediate fixing structure having a base plate for fixing the technical device in the vicinity of the passage opening, fixing the technical device on the intermediate fixing structure, the technical device being arranged on the face of the stretched flexible fabric located on the opposite side of the residual space.
