Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The electrical connection of circuit boards in linear lights during assembly is cumbersome, especially when accessing ceiling-mounted installations, due to difficult cabling and the need to disconnect and reassemble long linear lights for maintenance.
Innovation Solution
A linear light design featuring a support profile, optics, and a coupling adapter that allows detachable mounting of optics and circuit boards, with current paths on the circuit boards enabling power distribution through the coupling adapter, eliminating the need for external wiring and allowing vertical or horizontal coupling for efficient assembly and maintenance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If circuit boards are electrically connected during installation using traditional wiring methods, then the linear light can be assembled and function, but the electrical connection becomes cumbersome and difficult to access, especially in ceiling-mounted installations
Solution Approach 1:
The patent combines the electrical connection function with the mechanical mounting structure by integrating contact elements directly into the support profile and circuit board edges. This merging eliminates the need for separate wiring steps, making the electrical connection as simple as the mechanical assembly process itself.
Solution Approach 2:
The circuit boards are designed with edge-mounted contact elements that automatically engage with corresponding contacts in the support profile during the mounting process. This self-service mechanism eliminates the need for external wiring operations, as the electrical connection is established automatically when the circuit board is inserted into the support profile.
2Area of stationary object
If long linear lights are assembled with multiple circuit boards connected in series, then the light can cover larger areas, but maintenance requires disassembly from one end to the defective board, which is time-consuming
Solution Approach 1:
The linear light system is segmented into modular circuit board units that can be independently removed and replaced. Each circuit board is designed as a self-contained module with its own contact elements, allowing individual boards to be accessed and replaced without affecting the entire assembly.
Solution Approach 2:
The mounting system incorporates detachable connections that allow circuit boards to be easily inserted and removed from the support profile. This dynamic design enables maintenance personnel to access and replace specific defective boards by simply detaching the relevant section, rather than disassembling the entire linear light from one end.
3Shape
If the linear light is designed with a low profile for flush installation in ceilings and walls, then the aesthetic appearance and integration are improved, but the assembly and electrical connection become more difficult
Solution Approach 1:
The patent transitions the electrical connection interface from a lateral connection method to an edge-based connection method. By mounting contact elements on the edges of circuit boards and using corresponding contacts in the support profile, the system achieves compact integration without requiring lateral space for wiring, thus maintaining a low profile while simplifying assembly.
