Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If standard blind spot detection systems are used for motorcycles, then the system structure is simple, but the detection accuracy is poor due to not accounting for motorcycle lean and unique positioning
Solution Approach 1:
The patent combines object detectors with lean indicators into an integrated blind spot detection system. The object detectors detect potential vehicles in adjacent lanes while the lean indicators measure the motorcycle's lean angle, and the processor integrates both data streams to calculate accurate blind spot positions, resolving the contradiction between detection accuracy and system complexity.
Solution Approach 2:
The system dynamically adjusts blind spot detection parameters based on the motorcycle's real-time lean angle. As the motorcycle leans during turns, the processor modifies the calculated blind spot zones accordingly, ensuring continuous accurate detection despite changing vehicle orientation and position relative to adjacent lanes.
2Stability of the object's composition
If the driver position is in the center of the motorcycle, then the motorcycle positioning is stable, but the blind spot location becomes unpredictable and harder to detect
Solution Approach 1:
The processor acts as an intermediary that translates the stable center-positioned driver's perspective into accurate blind spot detection. It uses the lean angle data from indicators and object detector information to calculate where vehicles appear in the driver's field of view, bridging the gap between stable positioning and dynamic blind spot locations.
3Adaptability or versatility
If the motorcycle leans left and right during turning, then the motorcycle can navigate turns effectively, but the relative position of vehicles in adjoining lanes changes making blind spots unpredictable
Solution Approach 1:
The system continuously monitors the motorcycle's lean angle through indicators and uses this feedback to dynamically update the blind spot detection parameters. The processor adjusts the calculated blind spot zones in real-time based on the lean angle, ensuring that vehicle position detection remains precise even during dynamic turning maneuvers.
