Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If optical modules are arranged parallel to the circuit board, then the structure is simple and easy to manufacture, but it occupies more surface area and hinders airflow for heat dissipation
Solution Approach 1:
The patent transitions from a parallel arrangement (2D surface occupation) to a vertical arrangement (3D space utilization), allowing the optical module to stand perpendicular to the circuit board. This dimensional change reduces surface area occupation while improving airflow access from multiple directions, thereby enhancing heat dissipation without complicating the manufacturing process
2Ease of operation
If optical modules are arranged parallel to the circuit board, then the installation is straightforward, but it obstructs access to system panel information and complicates maintenance operations
Solution Approach 1:
By arranging the optical module vertically rather than parallel to the circuit board, the patent creates vertical clearance that improves access to system panel information and facilitates maintenance operations. The vertical orientation allows technicians to approach the module from the side or top without obstructing other components, making insertion, removal, and maintenance significantly easier
3Ease of manufacture
If optical modules are arranged parallel to the circuit board, then the design is conventional and easy to implement, but it makes it difficult to insert fiber optic patch cords
Solution Approach 1:
The vertical arrangement repositions the optical interface away from the plane of the circuit board, creating vertical clearance that facilitates the insertion and routing of fiber optic patch cords. This dimensional change allows patch cords to be routed vertically or at angles without interfering with other board-mounted components, significantly improving ease of connection while maintaining design simplicity

AI summary
The present application discloses a miniature vertical optical module, comprising a housing, a control circuit board, an optical receiving unit, an optical transmitting unit, a signal connector, and a positioning component. One end of the signal connector is connected to the control circuit board, and the other end extends to form signal terminals. The soldering surface of the signal terminals is oriented either vertically or parallel to the bottom surface of the housing. One side of the positioning component is mounted on the housing, while the other side extends toward the circuit board. The extension direction of the positioning component is perpendicular to the soldering surface on the circuit board. The miniature vertical optical module of the present application is designed to be mounted at a vertical or inclined angle relative to the circuit board, and may be adjusted appropriately to align with the system housing.
