Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If ultrasonic waves are emitted in a single direction by conventional distance measuring devices, then the device structure is simple, but the detection coverage is limited to obstacles in the same direction only
Solution Approach 1:
The patent transitions from single-direction ultrasonic emission to full circumferential emission by arranging multiple ultrasonic transmitters around a central axis, each emitting at different angles. This dimensional expansion from 1D to 360-degree coverage enables comprehensive spatial detection while maintaining relatively simple individual transmitter structures
Solution Approach 2:
The detection system is divided into multiple independent ultrasonic transmitters positioned at different angular locations. Each transmitter segment covers a specific angular range, and their combined coverage achieves full circumferential detection. This segmentation allows the system to maintain simple individual components while achieving complex overall functionality
2Adaptability or versatility
If multiple ultrasonic transmitters are arranged to achieve full circumferential detection, then the detection coverage is improved, but the device complexity increases
Solution Approach 1:
Each ultrasonic transmitter is designed with dual functionality: emitting ultrasonic waves for distance measurement and serving as a reflection surface for waves emitted by other transmitters. This multi-functionality reduces the need for separate dedicated reflection surfaces, thereby decreasing overall device complexity while maintaining comprehensive detection capability
Solution Approach 2:
The patent merges the functions of ultrasonic emission and reflection into the same physical components (the transmitters themselves). By combining these functions, the system reduces the total number of separate components needed, achieving high adaptability without proportionally increasing device complexity
3Adaptability or versatility
If conventional distance measuring devices are used, then the device structure is simple, but the application scope is greatly limited
Solution Approach 1:
The system implements feedback by having each ultrasonic transmitter not only emit waves but also receive reflected waves from other transmitters. This mutual feedback mechanism enables the system to reconstruct three-dimensional spatial distribution information and detect position changes of obstacles from multiple angular perspectives, significantly expanding application scope
Solution Approach 2:
The patent adds angular and spatial dimensions to the detection capability by arranging transmitters in a circumferential pattern. This dimensional enhancement allows the system to capture spatial distribution information that single-direction devices cannot detect, thereby preventing loss of critical environmental information
