Solution Overview
Problem
Existing light source devices, such as OLED and LED panels, require significant space and thickness due to electrical connections and their return lines, especially at crossover points, which complicates the mechanical and electrical fixing of connections external to the printed circuit board.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If contact-connections on all sides are used to achieve homogeneous luminous image, then luminous homogeneity is improved, but area requirement and overall thickness increase
Solution Approach 1:
The electrical connection system is segmented into individual connection elements distributed at corners or edge regions of the light source device, rather than requiring continuous contact-connections across the entire perimeter. Each segment handles localized electrical connection, eliminating the need for extensive wiring while maintaining electrical functionality.
Solution Approach 2:
The connection points are positioned at corner or edge regions (spatial dimension optimization), allowing electrical connections to be made at discrete locations rather than requiring planar contact-connections across the surface. This dimensional repositioning reduces the area occupied by wiring infrastructure.
2Illumination intensity
If contact-connections on all sides are used to achieve homogeneous luminous image, then luminous homogeneity is improved, but overall thickness increases particularly at crossover points
Solution Approach 1:
The wiring infrastructure is extracted from the interior space of the light source device and repositioned to external connections at corner or edge regions. This removes the thickness-consuming crossover points from the device structure, as wires no longer need to traverse through the device interior from one side to another.
Solution Approach 2:
The electrical connection path is segmented into separate connection elements at different locations, eliminating the need for long traversing wires that would increase thickness. Each segment connects locally at its position, avoiding the accumulation of wire layers that would occur with full-perimeter contact-connections.
3Stability of the object's composition
If additional mechanical fixing device is used to fix external connection, then mechanical stability is improved, but device complexity increases
Solution Approach 1:
The electrical connection element and mechanical fixing function are merged into a single integrated component. The connection element serves dual purposes: establishing electrical contact and providing mechanical anchoring for external wires, thereby eliminating the need for separate mechanical fixing devices and reducing overall device complexity.
Solution Approach 2:
The connection element at corner or edge regions is designed with multi-functionality, serving both as an electrical contact point and as a mechanical anchor for external wiring. This universal component replaces what would otherwise require separate specialized components for electrical and mechanical functions.
