Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If a translucent carrier material is used in the vision sensor system, then light transmission is improved, but the aesthetic appearance deteriorates
Solution Approach 1:
The patent applies composite materials by combining a translucent carrier material with a metallic coating layer. This composite structure allows the carrier material to provide light transmission functionality while the metallic coating layer provides aesthetic appearance, resolving the contradiction between these two requirements.
Solution Approach 2:
The metallic coating is applied selectively to specific surfaces of the carrier material (first surface, second surface, or both) depending on the desired aesthetic effect and light transmission requirements. This local application allows optimization of both appearance and light transmission in different areas.
2Shape
If a metallic coating is applied to the carrier material, then aesthetic appearance is improved, but light transmission deteriorates
Solution Approach 1:
The patent optimizes the metallic coating parameters including layer thickness, material composition, and optical properties to achieve a balance between aesthetic appearance and light transmission. By carefully controlling these parameters, the coating provides decorative effects while maintaining sufficient light transmission for vision sensor operation.
3Volume of moving object
If the carrier material is positioned close to the light-receiving element, then device compactness is improved, but optical performance deteriorates
Solution Approach 1:
The patent positions the carrier material at a distance from the light-receiving element along the optical axis, creating spatial separation that maintains optical performance. This distance positioning allows sufficient light transmission and optical quality while the overall device compactness is maintained through optimized spatial arrangement of other components.

AI summary
A vision sensor system is used for gesture recognition or another control system with a human-machine interface. In the vision sensor system, a vision sensor 1 is used in particular to check the presence, the orientation, the characteristics or the texture of an object 15. For this purpose, the vision sensor 1 has a housing 2 in which a light-receiving element 3 is arranged. At a distance from the light-receiving element 3 there is a cover made of a translucent carrier material 5 with a first surface 6 facing the light-receiving element 3 and a second surface 7 facing away from the light-receiving element 3, both located in the beam path 4 of the light-receiving element 3. The carrier material 5 has at least partially a translucent metallic coating 8, 9 on at least one of the first or second surfaces 6, 7 located in the beam path 4 of the light receiving element 3.
