Surface-Mount Downlight Suspension Assembly for Easier Installation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The installation of surface-mount downlights is inconvenient due to the need to lift and maneuver heavier devices while tightening screws, increasing the difficulty and time required for staff during the installation process.
Innovation Solution
A surface-mount downlight design that separates the installation into two parts: a lighter mounting top plate and a heavier downlight body, with a suspension mount assembly allowing the downlight body to be freely moved and secured to the mounting top plate through a rotational mechanism, reducing the need to lift the downlight body during installation.

1Reliability
If the surface-mount downlight is fixed using screw-lock connection, then the downlight body can be securely mounted to the ceiling, but the installation process becomes difficult and time-consuming due to the need to support the heavy downlight body while tightening screws
Solution Approach 1:
The mounting assembly is divided into two separate parts: a mounting top plate that remains fixed to the ceiling, and a downlight body that can be independently installed and removed. This segmentation allows the heavy downlight body to be separated from the mounting structure during installation, enabling workers to secure the lighter mounting top plate first, then attach the downlight body without needing to support its full weight during screw tightening.
Solution Approach 2:
The mounting top plate acts as an intermediary component between the ceiling and the downlight body. It provides a stable mounting interface that can be secured to the ceiling independently, then connects to the downlight body through the suspension mount assembly. This intermediary structure eliminates the need to support the heavy downlight body during the critical screw-tightening phase.
2Ease of operation
If the downlight body is separated into a mounting top plate and a downlight body, then the installation process becomes easier, but the device structure becomes more complex
Solution Approach 1:
The suspension mount assembly merges multiple functions into a single integrated mechanism: it provides both the mounting interface and the rotational locking mechanism in one component. The connecting plates and fixing blocks are combined into a unified suspension mount assembly that handles both attachment and positioning functions, reducing the number of separate components needed.
Solution Approach 2:
The mounting top plate serves multiple functions: it acts as the ceiling mounting interface, provides the rotational mechanism for locking, and serves as the structural support for the downlight body. This multi-functionality reduces the need for additional separate components, offsetting the apparent structural complexity with functional integration.
3Ease of operation
If the connecting plates and fixing blocks are positioned to avoid each other, then the downlight body can move freely for assembly, but the mounting mechanism requires additional rotational movement to secure
Solution Approach 1:
The mounting mechanism transitions from a static connected state to a dynamic rotational state during installation. The connecting plates and fixing blocks are initially positioned to allow free movement (avoiding each other), then the mounting top plate rotates to engage them in a locked position. This dynamic transformation enables easy assembly followed by secure mounting through a simple rotational motion.
Solution Approach 2:
The connecting plates and fixing blocks are pre-positioned in the mounting top plate in a configuration that allows free movement during approach and assembly. This preliminary positioning enables the downlight body to be easily brought into place without resistance, and the subsequent rotation is a simple final engagement step rather than a complex alignment process.

AI summary
A surface-mount downlight including and a mounting top plate (200; 400) and a downlight body (100; 300) comprising a hollow main body (110; 310) and a light source module (130; 330). The surface-mount downlight also has a suspension mount assembly which includes at least two bearing portions (220; 410) provided on the mounting top plate (200; 400) and at least two suspension fixings (121; 320) provided on the hollow main body (110; 310) corresponding to the at least two bearing portions (220; 410). With translational movement or rotational movement of the mounting top plate (200; 400) with respect to the downlight body (100; 300) in a direction substantially transverse to a suspension mount direction, the suspension mount assembly can switch between a first position and a second position in which the downlight body (100; 300) is mounted onto the mounting top plate (200; 400) .
