Lighting Device Coupling Members for Seamless Joint Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In building construction, the installation of lighting appliances adjacent to each other often results in visible misalignment due to distortions in building materials, leading to a stepped or inconspicuous joint between adjacent lighting units.
Innovation Solution
A lighting device comprising a first and second lighting appliance with a chassis, light sources, a fitting adapter, and a light-transmissive cover, where the appliances are arranged with their lateral surface portions abutting, and coupled using coupling members on the rear surface, allowing for adjustable positioning to conceal misalignment and create a seamless appearance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If lighting appliances are installed adjacent to each other on building materials, then lighting coverage is improved, but misalignment and visible joints occur due to material distortion
Solution Approach 1:
The lighting appliance is divided into separate modular units that can be independently installed and then coupled together. Each unit has standardized coupling members that enable precise connection, maintaining alignment even when installed on distorted building materials.
Solution Approach 2:
Coupling members act as intermediary elements between adjacent lighting appliances. These coupling members include positioning structures that bridge the gap between units, compensating for material distortion and ensuring precise alignment of the light-emitting surfaces.
2Manufacturing precision
If coupling members are added to connect lighting appliances, then alignment and continuity are improved, but device complexity increases
Solution Approach 1:
The coupling members are integrated into the overall lighting appliance structure, combining the functions of connection, positioning, and electrical connection into unified components. This merging reduces the number of separate parts and simplifies the installation process.
Solution Approach 2:
The coupling members serve multiple functions simultaneously: they mechanically connect adjacent lighting appliances, provide precise positioning to ensure alignment, and facilitate electrical connections between units. This multi-functionality reduces the need for separate components.
3Shape
If lateral surface portions abut against each other, then seamless appearance is improved, but adjustment flexibility is reduced
Solution Approach 1:
The coupling mechanism incorporates movable elements that allow the lighting appliances to be adjusted to different positions during installation. Once positioned, the coupling members secure the units with their lateral surfaces abutting, creating a seamless appearance while maintaining the ability to achieve various configurations.
Solution Approach 2:
The coupling members include pre-configured positioning structures that guide the alignment of lateral surfaces during installation. This preliminary positioning action ensures that when the units are coupled, their lateral surfaces naturally abut to create a seamless appearance without requiring precise manual adjustment.
