Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If flat light source apparatus is formed by combining predetermined shaped elements into desired shape, then the apparatus can achieve specific illumination areas, but the flexibility in shape assembly is limited and electric wiring becomes complicated
Solution Approach 1:
The light source board is divided into multiple unit boards that can be independently manufactured and then assembled. Each unit board contains light sources and connecting portions, allowing modular assembly into various shapes without complex wiring between units, as the connecting portions automatically establish electrical connections when units are joined
Solution Approach 2:
The connecting portion integrates both mechanical connection and electrical connection functions into a single structure. When unit boards are assembled together, the connecting portions simultaneously provide structural support and establish electrical pathways, eliminating the need for separate wiring operations
2Manufacturing precision
If predetermined shaped elements are combined to form desired shape, then specific illumination areas can be achieved, but manufacturing efficiency decreases due to complicated wiring work
Solution Approach 1:
The light source board is divided into multiple unit boards that can be independently manufactured and then assembled. Each unit board contains light sources and connecting portions, allowing modular assembly into various shapes without complex wiring between units, as the connecting portions automatically establish electrical connections when units are joined
Solution Approach 2:
The connecting portions are pre-formed on each unit board during manufacturing, so that when units are assembled, the electrical connections are automatically established without requiring additional wiring operations. This preliminary preparation of connection structures significantly reduces assembly time and complexity

AI summary
A flat light source apparatus has a light source board which comprises unit boards, each unit board having a printed circuit board and a light source formed on the printed circuit board, wherein the unit boards are arranged adjacent to each other at least in one direction, and any pair of the unit boards adjacent to each other is integrated by a connecting portion provided therebetween. The apparatus also has a main wire which extends along a plane of the light source board, wherein the main wire extends between adjacent unit boards via the connecting portion such that all of the unit boards are electrically connected to each other by the main wire. The apparatus further has a branch wire for supplying electric power to the light source, the branch wire being provided in each unit board and branching from the main wire in each unit board.
