Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If sensor signals are transmitted unprocessed through the serial transmission link, then complete signal evaluation can be performed in the controller, but the response time becomes unacceptably long due to the limited data transmission capacity
Solution Approach 1:
The patent divides the signal evaluation process into two segments: preprocessing in the optical sensor (generating partial results) and further evaluation in the controller. This segmentation allows the serial transmission link to carry only essential partial results rather than complete raw sensor data, reducing transmission time while maintaining evaluation flexibility in the controller.
Solution Approach 2:
The optical sensor performs preliminary preprocessing of sensor signals before transmission, generating partial results that capture essential information. This preliminary action reduces the data volume that needs to be transmitted through the serial link, enabling faster response times while preserving the ability to perform complete evaluation in the controller.
2Loss of time
If complete sensor signal evaluation is performed in the optical sensor, then response time is reduced, but the system loses flexibility in adapting to changing requirements
Solution Approach 1:
The evaluation process is segmented between the optical sensor (preprocessing) and controller (further evaluation). The controller can specify different configurations for the preprocessing, allowing flexibility in adapting to changing requirements while the time-critical preprocessing occurs in the sensor with fast response.
Solution Approach 2:
The system implements dynamic adaptability by allowing the controller to specify different configurations for the optical sensor's preprocessing based on changing requirements. This dynamic configuration capability enables the system to adapt its evaluation strategy without sacrificing response time, as the controller can adjust parameters for different operational scenarios.
3Loss of information
If all sensor data is transmitted through the serial transmission link, then complete evaluation is possible, but the data transmission capacity is exceeded and response time increases
Solution Approach 1:
The optical sensor extracts essential information from complete sensor signals by generating partial results that capture the most relevant data. This extraction process removes unnecessary data volume while preserving critical information needed for evaluation, enabling efficient transmission through the serial link without significant information loss.
Solution Approach 2:
Preprocessing in the optical sensor performs preliminary data reduction by generating partial results before transmission. This preliminary action identifies and transmits only the most essential sensor information through the serial link, maintaining data completeness for critical evaluation while dramatically reducing transmission time.
