Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If event-based vision sensors are integrated with other devices in electronic devices, then the functionality and versatility of the electronic device is improved, but noise interference and reduced detection accuracy occur
Solution Approach 1:
The control unit acts as an intermediary between the event-based vision sensor and other physical input/output units. It receives event signals from the sensor, identifies time periods when other units are operating, and selectively processes or filters signals based on this temporal information, thereby preventing noise interference while maintaining integration capability
Solution Approach 2:
The control unit preliminarily identifies time periods when physical input/output units are operating before processing event signals. By pre-determining these time windows, the system can proactively filter or mark signals generated during these periods, preventing noise from affecting detection accuracy before it can interfere with the vision sensor's measurements
2Speed
If event-based vision sensors operate at high speed with high temporal resolution, then the response speed is improved, but noise from simultaneous operation of other devices increases
Solution Approach 1:
The control unit operates periodically by monitoring the operational states of physical input/output units and rhythmically filtering event signals based on these periodic operations. This periodic identification and filtering of noise periods allows the high-speed vision sensor to maintain its rapid response capability while systematically eliminating noise interference that occurs during simultaneous operations of other devices
