Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the driver assistance system adjusts setting parameters to achieve a higher degree of fulfillment for one quality criterion, then that quality criterion is improved, but other quality criteria may deteriorate without clear visualization
Solution Approach 1:
The system implements feedback by continuously monitoring and displaying the effects of parameter changes on multiple quality criteria. When an operator adjusts a setting parameter, the system calculates and presents the expected effects on other quality criteria, enabling informed decision-making about trade-offs between competing objectives.
Solution Approach 2:
The graphical user interface uses color-coded visual indicators to represent the expected effects on quality criteria. Different colors indicate positive, neutral, or negative effects, allowing operators to quickly assess the impact of parameter changes without analyzing numerical data, thus preventing information loss.
2Loss of information
If the system provides detailed information about all quality criterion interactions, then operator awareness is improved, but the complexity of the control system increases
Solution Approach 1:
The system applies local quality by providing detailed information specifically at the point where the operator needs it - in the graphical user interface during parameter adjustment. The complexity is localized to the information processing and display layer, while the core control system remains relatively simple, focusing only on calculating and presenting the effects.
Solution Approach 2:
The graphical user interface acts as an intermediary between the simple control system and the operator. It translates complex parameter interactions into easily understandable visual representations, allowing the control system to remain relatively simple while still providing comprehensive information about quality criterion interactions.
3Ease of operation
If the system visualizes all expected effects of parameter changes, then operator decision-making is improved, but the processing time and computational load increase
Solution Approach 1:
The system performs preliminary calculations of quality criterion effects based on pre-established models and relationships. When an operator adjusts a parameter, the system quickly retrieves and displays the pre-calculated expected effects, minimizing processing time while still providing comprehensive information for decision-making.
