Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual control of scanning devices is used, then ease of operation is improved, but measurement precision deteriorates due to human error and inconsistent coverage
Solution Approach 1:
The system uses automated scanning control where the scanning device independently executes pre-programmed scanning patterns and sequences without requiring continuous manual intervention. The device self-adjusts parameters, follows predetermined paths, and automatically processes data, eliminating human error while maintaining operational simplicity through automated self-service mechanisms.
Solution Approach 2:
The system incorporates feedback mechanisms where detection results are continuously monitored and fed back to adjust scanning parameters in real-time. This closed-loop control ensures consistent coverage by automatically correcting deviations from the intended scanning pattern, thereby improving measurement precision without requiring manual intervention.
2Device complexity
If traditional detection systems are used, then device complexity is reduced, but loss of information increases due to incomplete or inaccurate assessments
Solution Approach 1:
The system transitions from traditional single-point or single-axis scanning to multi-dimensional scanning using multiple axes of motion and multiple sensing elements. This dimensional expansion enables comprehensive coverage of the target area, capturing complete spatial information and eliminating data gaps that occur in traditional systems.
Solution Approach 2:
The scanning system is divided into multiple independent scanning axes and detection elements that operate simultaneously or sequentially. Each segment covers a specific portion of the target area, and the results are integrated to form a complete assessment, ensuring no information is lost while maintaining manageable system complexity through modular segmentation.
3Ease of operation
If fixed scanning patterns are used, then ease of operation is improved, but adaptability deteriorates when environmental conditions change
Solution Approach 1:
The scanning system employs dynamic scanning patterns that can adapt in real-time to changing environmental conditions. Pre-programmed scanning sequences serve as base patterns, but the system dynamically adjusts parameters such as scanning speed, axis movement ranges, and detection frequencies based on sensor feedback about environmental changes, maintaining both ease of operation and adaptability.
Solution Approach 2:
The system stores multiple pre-configured scanning patterns with different parameters for various application types and environmental conditions. When conditions change, the system automatically selects and switches between different parameter sets, allowing easy adaptation to new situations without requiring complex manual reconfiguration or changing the fundamental ease of operation.
