Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mounting systems for recessed ceiling and wall luminaires are complex and difficult to adapt to varying structural conditions, such as drywall thickness, leading to increased component variability and installation complexity.
Innovation Solution
A universal assembly set comprising a mounting sleeve with contact portions and a luminaire housing featuring locking elements that can be easily transferred between fixing and release positions using handles, allowing for secure and tool-free installation in various building structures, including drywall, cast walls, and ceilings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional mounting systems with carrier elements and screw fastening are used, then reliable fixation is achieved, but device complexity and installation time increase
Solution Approach 1:
The mounting system is segmented into a mounting sleeve fixed in the building structure and a luminaire housing with integrated locking elements. This separation allows the mounting sleeve to provide stable fixation while the luminaire housing provides easy installation through snap-fit locking elements that engage with the mounting sleeve.
Solution Approach 2:
The traditional screw-fastening mechanical system is replaced with a snap-fit locking mechanism. The locking elements on the luminaire housing engage with the mounting sleeve through elastic deformation and geometric interlocking, eliminating the need for screws and complex carrier elements while maintaining reliable fixation.
2Adaptability or versatility
If multiple mounting systems are used to adapt to different building structures, then adaptability is improved, but device complexity and storage costs increase
Solution Approach 1:
The mounting sleeve is designed as a universal component that can be fixed in various building structures (drywall, cast walls, ceilings) using different methods (screw-fastening, plastering-in). The luminaire housing with standardized locking elements can be installed in any mounting sleeve, creating a universal system that adapts to different building structures without requiring multiple specialized mounting systems.
3Stability of the object's composition
If carrier elements are fixedly connected to building structure, then stable mounting is achieved, but installation time and labor increase
Solution Approach 1:
The mounting sleeve is pre-fixed in the building structure during construction or renovation, creating a ready-to-use mounting point. When the luminaire needs to be installed, the locking elements simply need to be engaged with the pre-positioned mounting sleeve, eliminating the need to fix carrier elements at the time of luminaire installation and significantly reducing installation time.
4Ease of operation
If snap-fit connections are used for easy installation, then ease of operation is improved, but fixation reliability may be compromised
Solution Approach 1:
The locking elements are nested within the luminaire housing and engage with corresponding features in the mounting sleeve. This nested arrangement allows the locking elements to be easily inserted and engaged (providing ease of operation) while creating a secure interlocking connection that ensures reliable fixation. The elastic deformation of the locking elements provides both the snap-fit action for easy installation and the mechanical interlocking for reliable connection.

AI summary
An assembly set for recessed ceiling and wall luminaires, comprises a mounting sleeve and a luminaire housing, which is adapted to be installed in the mounting sleeve, the mounting sleeve being mountable in a wall or ceiling opening. The mounting sleeve is provided with contact portions extending, on the side of the mounting sleeve facing away from the wall or ceiling opening, perpendicular to a wall of the mounting sleeve into the interior of the latter. The luminaire housing comprises at least two locking elements extending beyond the circumference of the luminaire housing, wherein the locking elements of the luminaire housing engage behind the contact portions of the mounting sleeve at the fixing position, and the locking elements are operatively connected to handles in the interior of the luminaire housing such that the locking elements can be transferred from the fixing position to a release position by moving the handles towards each other.
