Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If connectors are positioned on multiple sides to supply power and control signals to light source assemblies, then reliability of power supply and signal transmission is improved, but bezel area increases
Solution Approach 1:
Multiple connectors (first positive electrode connector, second positive electrode connector, first negative electrode connector, second negative electrode connector) are merged into a single integrated connector structure positioned on one side of the display device. This consolidation maintains all necessary electrical connections while reducing the bezel area occupied by connector arrangements.
Solution Approach 2:
The connector structure extends in the thickness direction of the display device, utilizing the z-axis dimension rather than only the planar x-y dimensions. This allows connectors to be positioned on one side while maintaining electrical connections to electrodes on opposite sides of the display panel, effectively reducing bezel area.
2Area of stationary object
If multiple connectors are positioned on one side to reduce bezel area, then bezel area is reduced, but device complexity increases
Solution Approach 1:
The integrated connector structure performs multiple functions simultaneously: it provides electrical connections for both positive and negative electrodes, transmits power and control signals, and maintains a compact form factor. This multi-functionality reduces the number of separate components needed, thereby reducing overall device complexity despite the advanced design.
3Area of stationary object
If light source assemblies are arranged densely to improve display coverage, then display area utilization is improved, but power supply and signal distribution becomes more difficult
Solution Approach 1:
Electrical connections extend in the thickness direction of the display device, allowing connectors on one side to reach electrodes on opposite sides. This three-dimensional routing enables dense light source assembly arrangements while maintaining simplified power and signal distribution through the integrated connector structure.
