Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If ultrasonic array sensors and individual sensors are integrated into a combined assembly, then wiring complexity and cabling efforts are reduced, but separate integration of sensors requires complex wiring and separate control units
Solution Approach 1:
The patent combines multiple ultrasonic sensors (array sensors and individual sensors) into a single integrated assembly with shared electronic components and common wiring infrastructure. This merging approach reduces the overall wiring complexity and eliminates the need for separate control units for each sensor type, while maintaining the functional independence of each sensor through integrated signal processing circuits.
2Reliability
If separate module control units are used for each sensor type, then signal processing is dedicated and reliable, but electronic hardware and cabling requirements increase
Solution Approach 1:
The patent implements a universal control architecture where a single control unit handles signal processing for both ultrasonic array sensors and individual ultrasonic sensors. This multi-functional approach maintains reliable signal processing through standardized processing pathways while reducing the total quantity of electronic hardware by eliminating redundant control units and their associated cabling.
3Ease of operation
If ultrasonic sensors are wired in star configuration to central controller, then signal processing is centralized and manageable, but cabling efforts and production costs increase
Solution Approach 1:
The patent reduces production complexity by integrating multiple sensors into assemblies that require fewer wiring connections to the central controller. By combining sensors that share common wiring requirements into single assemblies, the overall cabling effort is reduced, streamline 生产 process, and improve production efficiency while maintaining centralized signal processing capability.
