Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If manual intervention by operators is used to control process parameters, then flexibility in adjusting to changing conditions is improved, but reproducibility and consistency deteriorate
Solution Approach 1:
The power supply system performs self-adjustment by automatically detecting process parameters through sensors and modifying its own output voltage and current based on measured values, eliminating the need for manual operator intervention while maintaining consistent, reproducible control
Solution Approach 2:
The system continuously measures process parameters using sensors and uses this feedback information to automatically adjust the electrical output, creating a closed-loop control system that ensures both adaptability to changing conditions and reproducible results
2Reliability
If external predefined scripts are used to control process parameters, then reproducibility is improved, but adaptability to deviations and changing conditions deteriorates
Solution Approach 1:
The control system transitions from static predefined scripts to dynamic adaptive control, where the power supply continuously adjusts its output based on real-time sensor measurements, allowing it to respond to deviations while maintaining reproducible operation through systematic control
Solution Approach 2:
The system incorporates continuous feedback from sensors that monitor process parameters, enabling the power supply to detect deviations from target values and automatically adjust its output, combining the reproducibility of programmed control with the adaptability of real-time response
3Device complexity
If fixed output values are set in advance for preset environmental conditions, then device complexity is reduced, but adaptability to complex applications and changing conditions deteriorates
Solution Approach 1:
The power supply automatically detects environmental conditions and process parameters through integrated sensors and self-adjusts its output without requiring complex external configuration, maintaining simplicity while achieving high adaptability to different applications and changing conditions
Data Source
AI summary
A power supply comprises a control unit for adjusting a power output by the power control unit in response to a control signal. The power supply further includes a processing unit configured to generate the control signal using a control model and based at least on one or more sensor signals supplied to the processing unit. The processing unit is configured to communicate via an interface with an external processing entity to receive a data set for generating the control model and/or to receive the control model, and/or to transmit the model to the external processing entity.
