Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If components are sourced from different manufacturers and assembled separately, then component selection flexibility is improved, but system integration complexity and packaging efficiency deteriorate
Solution Approach 1:
The patent combines the driver circuit board and lighting circuit board into a single integrated housing structure with a unified PCB substrate. The driver components and lighting components are mounted on the same board, eliminating the need for separate assembly of multiple components from different manufacturers. This integration resolves the technical contradiction by maintaining component selection flexibility through modular design while significantly reducing system integration complexity and improving packaging efficiency.
2Adaptability or versatility
If multiple separate components are used, then functional versatility is improved, but packaging efficiency and final system configuration deteriorate
Solution Approach 1:
The patent implements a nested structure where the lighting circuit board is positioned within the housing that also contains the driver circuit board. The lighting PCB is inserted into a cavity in the driver PCB housing, creating a compact nested arrangement. This nesting approach maintains functional versatility by keeping both driver and lighting functions available while dramatically improving packaging efficiency and reducing the overall volume of the lighting system.
3Ease of operation
If components are designed for easy interchangeability, then ease of configuration is improved, but connection reliability and electrical contact stability may deteriorate
Solution Approach 1:
The patent incorporates pre-designed alignment features, guide pins, and predetermined mating interfaces on both the driver PCB and lighting PCB. These preliminary structural preparations ensure that when components are interconnected, they automatically align and establish reliable electrical contacts without requiring complex assembly procedures. This preliminary action maintains ease of configuration while ensuring connection reliability through built-in alignment and contact assurance mechanisms.

AI summary
A solid state lighting assembly (10) includes a socket (12) having a base wall (14) having a first side (18) and a second side (20), and a first cavity (22) proximate the first side (18) and a second cavity proximate the second side (20). Contacts are held by the base wall (14). The contacts have mating fingers extending into the first and second cavities (22). A lighting printed circuit board (PCB) (30) is removably positioned within the first cavity (22) with at least one lighting component (32) configured to be powered when electrically connected to corresponding mating fingers of the contacts. The lighting PCB (30) is initially loaded into the first cavity (22) in an unmated position and moved in the first cavity (22) to a mated position. A driver PCB is positioned within the second cavity and is electrically connected to corresponding mating fingers of the contacts. The driver PCB has a power circuit configured to supply power to the lighting PCB (30) when electrically connected to the contacts.
