Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a variety of optoelectronic devices are provided for each operating parameter to be measured, then measurement capability is improved, but production cost and storage cost increase
Solution Approach 1:
The patent implements a universal carrier device that can accommodate multiple different optoelectronic components (transmitters and receivers) through standardized contact chambers and electrically conductive contact tracks. This single carrier design replaces the need for multiple specialized carrier devices, enabling one carrier to serve multiple measurement functions while reducing production and storage costs.
Solution Approach 2:
The carrier device is segmented into multiple contact chambers, each capable of holding different optoelectronic components. This segmentation allows flexible configuration where specific chambers can be populated with transmitters or receivers depending on the measurement requirement, while other chambers remain empty or contain different components, enabling versatile measurement capability from a single carrier.
2Adaptability or versatility
If carrier devices are adapted to specific optoelectronic components with specific geometric designs, then component compatibility is improved, but development effort increases
Solution Approach 1:
The patent creates a universal carrier device with standardized contact chambers and electrically conductive contact tracks that can accommodate multiple types of optoelectronic components. This universal design eliminates the need to develop separate carrier geometries for different components, significantly reducing development effort while maintaining compatibility through the standardized interface.
Solution Approach 2:
The carrier device enables dynamic reconfiguration of optoelectronic components through the standardized contact chamber design. Different components can be installed or removed from contact chambers depending on measurement requirements, allowing the system to adapt to different applications without requiring physical modification of the carrier itself.
3Reliability
If contact chambers are optically isolated, then optical crosstalk is prevented, but manufacturing complexity increases
Solution Approach 1:
The carrier device divides the contact area into multiple separate contact chambers that are optically isolated from each other. This segmentation prevents optical crosstalk between adjacent transmitters and receivers by providing physical separation within each chamber, while the overall carrier remains a single integrated component that can be manufactured using standard processes.

AI summary
The invention presents an optoelectronic apparatus, in particular an optoelectronic sensor apparatus, comprising a carrier device (12) which has a longitudinal extent and a transverse extent, wherein the carrier device (12) has a leadframe with a plurality of electrically conductive contact tracks (92, 92') which are oriented parallel to the longitudinal extent, and wherein the carrier device has, on a top side, a plurality of contact chambers which are oriented parallel to the transverse extent and are formed by separating webs (104). Each of the contact tracks (92, 92') can be electrically contacted in each contact chamber in order to be able to install at least one optoelectronic transmitter (40) and/or at least one optoelectronic receiver (42) in the respective contact chambers with variable population.
