Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If light source boards are fixed using conventional methods, then assembly is simple, but the fixing structure interferes with power supply lines and reduces reliability
Solution Approach 1:
The light source board is divided into multiple board bars, each with its own coupling portion and bar fixer. This segmentation allows the fixing structure to be distributed and optimized independently, preventing interference with power supply lines while maintaining overall structural integrity and reliability.
Solution Approach 2:
The coupling portion acts as an intermediary element between the board bar and the bar fixer. It provides a dedicated interface for mechanical attachment that is spatially separated from the power supply lines, thereby preventing interference while ensuring secure fixing.
2Productivity
If board fixers are positioned to securely attach board bars, then manufacturing efficiency increases, but repair and replacement become more difficult
Solution Approach 1:
The modular board bar design with discrete coupling portions allows individual components to be independently accessed and replaced. The segmentation enables efficient assembly during manufacturing while facilitating targeted repair without requiring complete disassembly of the light source board.
Solution Approach 2:
The fixing structure is designed to be dynamically adjustable, allowing bar fixers to be easily positioned and secured during assembly, yet permitting controlled disassembly for repair purposes. This dynamic design optimizes both manufacturing efficiency and ease of maintenance.
3Ease of manufacture
If coupling portions are located on board bars, then fixing is simplified, but power supply lines are interfered with
Solution Approach 1:
The coupling portions are strategically positioned at specific locations on the board bars where they do not overlap with power supply line routes. This local optimization ensures that the fixing function is achieved without creating harmful interference with electrical connections.
Solution Approach 2:
The coupling portions and bar fixers utilize the vertical dimension and lateral spacing to position fixing elements in three-dimensional space away from the planar power supply lines. This dimensional separation eliminates interference while maintaining effective mechanical attachment.
