Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple sensors and processing units are integrated to improve safety monitoring accuracy, then measurement precision and reliability improve, but device complexity increases
Solution Approach 1:
The patent combines multiple sensing functions (gyroscope for lean angle, infrared sensor for temperature) and processing capabilities (microprocessor for real-time analysis) into a single integrated safety device unit that attaches to the motorcycle, eliminating the need for separate distributed systems and reducing overall complexity while maintaining measurement precision
Solution Approach 2:
The safety device performs multiple functions simultaneously: it measures lean angle via gyroscope, monitors tire temperature via infrared sensor, processes data through microprocessor, and provides visual feedback via display, all within one unified device that serves as both sensor array and control system
2Reliability
If a safety device is designed to integrate multiple essential parameters for real-time performance modeling, then safety effectiveness improves, but ease of operation deteriorates due to installation complexity
Solution Approach 1:
The safety device is designed as a self-contained modular unit with all necessary components (sensors, microprocessor, display) integrated together, allowing it to be installed as a single segment on the motorcycle without requiring integration with existing electronic control circuits, thereby maintaining safety effectiveness while simplifying installation
Solution Approach 2:
The device serves as an intermediary safety system that operates independently of the motorcycle's native electronic systems, using its own integrated sensor array and processing unit to provide safety monitoring without requiring modification or connection to pre-existing electronic control circuits
3Loss of information
If real-time data processing and display are implemented to provide immediate feedback, then loss of information is reduced, but use of energy increases
Solution Approach 1:
The microprocessor processes sensor data and updates the display in periodic cycles rather than continuously, updating the visual display at optimized intervals that provide sufficient real-time feedback information while allowing the processing unit to enter low-power states between updates, thus reducing overall energy consumption
