Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple radar sensors are installed on the bicycle to detect surrounding vehicles and obstacles, then the safety and awareness of the rider is improved, but the device complexity and cost increase
Solution Approach 1:
The system divides the sensing function into multiple independent radar sensors positioned at different locations (front, rear, left, right) of the bicycle. Each sensor independently detects objects in its specific direction, and the processing module integrates these segmented detection results to provide comprehensive surrounding awareness, resolving the contradiction between safety improvement and device complexity
Solution Approach 2:
The processing module serves multiple functions: it receives data from all radar sensors, calculates sensing distances, determines safety status, and controls warning lamps. This multi-functional design reduces overall system complexity by consolidating processing tasks in a single module while maintaining comprehensive safety coverage
2Measurement precision
If radar sensors are used to detect objects at long distances, then the sensing distance is improved, but the power consumption increases
Solution Approach 1:
The radar sensors perform periodic scanning of the surrounding environment rather than continuous monitoring at full power. The system adjusts the scanning frequency and power level based on the current riding situation, maintaining long sensing distance capability while reducing average power consumption through intermittent operation
Solution Approach 2:
The system dynamically adjusts the sensing distance and power consumption based on the rider's speed and surrounding conditions. At higher speeds, the sensing distance is increased with corresponding power adjustment, while at lower speeds the system conserves energy. This dynamic adaptation resolves the contradiction between measurement precision and energy usage
3Reliability
If warning lamps are activated to alert riders of nearby vehicles, then the safety warning function is improved, but the visibility and attention of the rider may be distracted
Solution Approach 1:
The warning lamps use different colors to convey different levels of urgency and safety status. For example, yellow lamps indicate moderate risk while red lamps indicate immediate danger, allowing the rider to quickly assess the situation without being overly distracted. The color-coding system maintains safety warning effectiveness while preserving rider attention and situational awareness
