Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of repair
If a pluggable light source module is used to enable easy replacement of the light source, then the light source can be replaced independently without replacing other components, but the available space on the panel is limited and insufficient space for heat dissipation holes is available
Solution Approach 1:
The patent combines the optical input interface and optical output interface into a single light source module. The module includes a substrate with a light source, an electrical interface for power supply, a first optical interface for optical signal input/output, and integrates these components so that the optical interfaces are disposed on different sides of the module body, merging multiple functions into one replaceable unit.
Solution Approach 2:
The patent utilizes three-dimensional space by disposing the first optical interface and second optical interface on different sides of the module body. This spatial arrangement allows optical signals to pass through the module from opposite directions without requiring separate panel openings, effectively using the module's internal volume to resolve the panel space constraint.
2Adaptability or versatility
If separate optical input/output ports are disposed on the panel, then optical signals can be transmitted, but the panel space is occupied and heat dissipation space is insufficient
Solution Approach 1:
The patent extracts the optical input and output interfaces from the panel structure and relocates them to an independent light source module. The module is connected to the panel through a detachable connection, allowing the optical interfaces to be positioned away from the panel surface. This extraction eliminates the need for separate optical ports on the panel, freeing up panel space for heat dissipation while maintaining optical signal transmission capability.
3Area of stationary object
If the light source module integrates multiple interfaces, then panel space is saved, but the module structure becomes more complex
Solution Approach 1:
The patent segments the optical communication system into distinct functional modules: the light source module containing the light source and optical interfaces, and the panel structure. By segmenting the system this way, the complex multi-interface structure is contained within a self-contained module that can be easily replaced, while the panel structure remains simple and requires minimal modifications.
