Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If BUS interface or radio module is used for parameter data transmission, then data transmission capability is improved, but device complexity and security risks increase
Solution Approach 1:
The patent extracts the parameter data transmission function from complex communication interfaces (BUS, radio modules) and implements it through a simple optical code reading mechanism using the existing light receiver, eliminating the need for dedicated communication hardware
Solution Approach 2:
The patent replaces electronic communication systems (BUS interfaces, radio modules) with an optical information carrier system where parameter data is transmitted through visually readable codes, substituting complex electronic data transmission with simple optical detection
2Device complexity
If manual input via control elements is used, then device complexity is reduced, but ease of operation and accuracy deteriorate
Solution Approach 1:
The system automatically reads parameter data from visual codes through the light receiver, eliminating the need for manual data entry by operators. The measuring device serves itself by optically acquiring parameter data without human intervention in the data input process
3Ease of operation
If radio module is used for parameter data transmission, then ease of operation is improved, but reliability and security worsen due to electromagnetic interference and manipulation risks
Solution Approach 1:
The patent removes the vulnerable radio module from the system and extracts the essential function of parameter data transmission to a simple optical code reading mechanism that is inherently more secure and immune to electromagnetic interference
Solution Approach 2:
The patent converts the limitation of using only existing light receiver components into a benefit by creating a secure optical communication system that naturally resists electromagnetic interference and manipulation, turning a potential disadvantage into a security advantage

AI summary
A measuring device for triangulation measurement comprises a light transmitter for emitting illumination light; transmitting optics for guiding the illumination light in a light pattern towards an object; a light receiver for capturing an image; and a control and evaluation unit which, in a measurement mode, determines shape or position information of the object based on a measurement image from the light receiver. According to the invention, the control and evaluation unit can switch between measurement mode and data reading mode, wherein, in data reading mode, the control and evaluation unit evaluates the image with respect to coded parameter data and uses the parameter data read in this way in a subsequent measurement mode. Furthermore, a corresponding method for triangulation measurement is described.
