Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a separate camera mount is used in the Scheimpflug adapter, then the camera can be permanently fixed and adjusted, but the mechanical complexity and cost increase
Solution Approach 1:
The patent merges the camera mount functionality directly into the camera body by providing a rotatable camera connection (16) that is integrally formed as part of the camera housing. This eliminates the need for a separate camera mount component, reducing mechanical complexity while maintaining the ability to permanently fix and adjust the camera position relative to the lens connection.
2Manufacturing precision
If a Scheimpflug adapter is used to adjust camera angle, then the object plane and sensor plane alignment can be corrected, but the working distance between lens and sensor increases
Solution Approach 1:
The patent implements dynamic adjustment mechanisms that allow the lens connection (18) to be pivoted relative to the camera connection about a pivot axis intersecting the sensor plane. This dynamic positioning enables precise alignment of the object plane and sensor plane while maintaining a compact working distance, as the lens can be positioned closer to the sensor compared to traditional Scheimpflug adapters.
3Ease of operation
If a complex camera connection design is used, then the camera can be permanently mounted and adjusted, but the cost increases particularly in industrial applications
Solution Approach 1:
The patent designs the camera connection (16) with universal functionality that combines both permanent mounting capability and adjustment capability in a single integrated structure. The rotatable connection allows the camera to be securely mounted while enabling occasional readjustment of the camera angle, eliminating the need for separate mounting brackets or adjustment mechanisms and thereby reducing production costs for industrial applications.

AI summary
The invention relates to a Scheimpflug camera (10) comprising - a camera connection (16) for mounting a camera (12), - a camera (12) which is mounted in the camera connection (16), comprising a sensor (123) which lies on a sensor plane and camera electronics (126) which are connected to the sensor (123), wherein the central surface normal of the sensor (123) defines a first optical axis, - a lens connection (18) for rigidly mounting a lens which defines a second optical axis, said lens connection being pivotal relative to the camera connection (16) about a pivot axis that intersects the first optical axis on the sensor plane such that the first and second optical axis run coaxially to each other or intersect each other on the sensor plane according to the pivot position, and - an installation base (20) in which the lens connection (18) is rotatably mounted about the second optical axis. The invention is characterized in that the camera (12) has a cylindrical sensor support (121), - on the front end face (122) of which the sensor (123) is fixed in a central position and in an orientation that is normal relative to the cylinder axis of the sensor support (121) and - the rear end face (124) of which has an interface for the camera electronics (126) that are arranged in the interior of the sensor support (121). The camera connection (16) has a central circular through-opening in which the sensor support (121) is directly mounted in an axially fixed manner and in a rotatable manner about the cylinder axis of the sensor support.
