Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If vibration sensors and speed measurements are used to evaluate driving quality, then the ability to assess driving behavior is improved, but the device complexity increases
Solution Approach 1:
The system uses a multi-functional approach where vibration sensors serve multiple purposes: detecting road conditions, evaluating driving behavior, and assessing vehicle status. The same sensor data is processed to generate both diagnostic information and driving quality metrics, reducing the need for separate dedicated sensors for each function.
Solution Approach 2:
The patent introduces an intermediary processing layer that receives raw vibration and speed data, processes it through reference comparisons, and generates meaningful driving quality assessments. This intermediary system acts as a mediator between the simple sensor inputs and the complex evaluation outputs, managing the complexity through structured data processing rather than hardware complexity.
2Measurement precision
If real-time vibration and speed measurements are continuously monitored, then the accuracy of driving quality evaluation is improved, but the energy consumption increases
Solution Approach 1:
The system implements periodic monitoring where vibration and speed measurements are taken at specific intervals rather than continuously. The processor compares measurements against reference values at discrete time points, providing accurate driving quality evaluation while reducing energy consumption by keeping sensors and processing in low-power states between measurement cycles.
Solution Approach 2:
The system dynamically adjusts monitoring parameters based on driving conditions. When abnormal vibrations or speed changes are detected, the measurement frequency increases to capture detailed driving quality data. During normal operating conditions, the monitoring frequency is reduced, balancing accuracy requirements with energy conservation.
