1Ease of operation
If angled connection pins and specialized components are used to produce lateral connections in electro-optical interfaces, then the connection orientation is achieved, but the device complexity and manufacturing cost increase
Solution Approach 1:
Instead of using angled connection pins to achieve lateral connection orientation, the patent inverts the approach by using a planar printed circuit board with standard right-angled pins and achieving the lateral connection through the orthogonal arrangement of components on the board. This eliminates the need for specialized angled pins while maintaining the lateral connection function.
Solution Approach 2:
The patent changes the parameter of connection pin angle from angled (non-90 degrees) to standard right angles (90 degrees), and achieves the lateral connection effect through the orthogonal layout of the printed circuit board itself. This parameter change simplifies manufacturing while achieving the same functional result.
2Ease of operation
If angled connection pins and specialized components are used for lateral connections, then the connection is achieved, but production costs increase
Solution Approach 1:
The patent replaces expensive specialized angled connection pins with standard, inexpensive right-angled connection pins that can be mass-produced. The lateral connection function is achieved through the low-cost orthogonal layout of the printed circuit board rather than through costly specialized components.
Solution Approach 2:
The patent extracts the orientation function from the connection pins themselves and transfers it to the printed circuit board layout. By removing the need for angled pins and achieving orientation through the board's orthogonal structure, the manufacturing process becomes simpler and more cost-effective.
3Ease of operation
If angled connection pins are used for lateral connections, then the connection orientation is achieved, but the lateral spacing requirements increase
Solution Approach 1:
The patent moves the orientation function from the horizontal plane (angled pins requiring lateral spacing) to the vertical plane (orthogonal pins with standard spacing). By using right-angled pins mounted on an orthogonally arranged printed circuit board, the lateral spacing requirement is reduced to standard pin spacing, freeing up lateral space.

AI summary
A method for producing a lateral connection of an electro-optical interface is specified. In the method, a printed circuit board having a non-curved center plane is provided. An electro-optical component and an electrical component are arranged and oriented with respect to one another in a connection region. A first section of the printed circuit board is deformed in such a way that the center plane encloses an angle with the non-deformed layer in the region of the first section. An electro-optical interface and a control device are also specified.
