Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If real-time feedback system is implemented to provide braking assessment information to drivers, then driver awareness of braking impact on emissions is improved, but device complexity increases
Solution Approach 1:
The patent implements a feedback mechanism that provides real-time braking assessment information to drivers through a display unit. The system calculates a braking assessment index based on detected physical quantities (braking force, speed, temperature) and feeds this information back to the driver, enabling them to adjust their braking behavior to reduce particulate emissions while maintaining necessary braking performance.
Solution Approach 2:
The patent introduces a control unit as an intermediary that processes detected physical quantities from sensors and generates braking assessment information. This intermediary component translates complex sensor data into simplified feedback for the driver, reducing the perceived system complexity while maintaining effective communication of braking impact.
2Measurement precision
If comprehensive physical quantities are detected and processed to calculate braking assessment index, then measurement precision of emission impact is improved, but device complexity increases
Solution Approach 1:
The patent segments the braking assessment system into distinct functional components: detection means for measuring physical quantities (braking force, speed, temperature), a control unit for processing data and calculating the braking assessment index, and a display unit for presenting information. This segmentation allows each component to specialize in specific tasks, improving measurement precision while managing overall system complexity through modular design.
Solution Approach 2:
The control unit serves multiple functions: it processes data from various sensors, calculates the braking assessment index using predetermined algorithms, determines appropriate feedback information, and controls the display unit. This multi-functionality reduces the need for separate dedicated components for each task, thereby managing device complexity while maintaining comprehensive assessment capabilities.
