Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual measurement methods are used with a measurement technician holding an insulating rod with a measuring microphone, then the measurement can be performed with simple equipment, but the positioning accuracy of the measuring microphone is poor and the reproducibility is limited
Solution Approach 1:
The measuring robot autonomously navigates along the measurement path and positions itself at measurement points without human intervention. The robot independently performs the measurement task, eliminating the need for manual positioning by a technician while achieving high positioning accuracy through automated control systems and sensors.
Solution Approach 2:
The manual mechanical positioning system (technician holding insulating rod) is replaced with an automated robotic system that uses sensors, motors, and control algorithms to achieve precise positioning. This substitution transforms a manually-operated mechanical system into an automated electromechanical system with superior positioning capabilities.
2Reliability
If manual measurement methods are used with technicians working in the vicinity of high-voltage machine parts, then the measurement can be performed with simple equipment, but there is a significant risk potential for people
Solution Approach 1:
The measuring robot autonomously performs the measurement task in the high-voltage area without requiring human presence. The robot navigates, positions microphones, and transmits data independently, completely eliminating exposure of personnel to high-voltage risks while maintaining measurement capabilities.
Solution Approach 2:
The measuring robot acts as an intermediary between the measurement personnel and the high-voltage measurement environment. It enables remote data collection from dangerous areas by serving as a mediator that can operate in conditions unsuitable for human workers, thus protecting personnel while achieving measurement goals.
3Productivity
If manual measurement methods are used with over 100 individual measurements required for a high-voltage choke, then the measurement can be performed with simple equipment, but a considerable amount of time is required
Solution Approach 1:
The measuring robot continuously moves along the measurement path and performs measurements at multiple points without interruption. The automated system eliminates gaps between measurements and enables continuous data collection, significantly increasing productivity compared to manual methods where technicians must reposition equipment between measurements.
Solution Approach 2:
The measurement system transitions from static manual positioning to dynamic automated movement. The robot dynamically navigates along the measurement path, automatically adjusts positions, and continuously collects data, enabling rapid completion of numerous measurement points that would be time-consuming performed manually.
4Measurement precision
If the measurement is carried out in the vicinity of machine parts that are at high voltage potential, then the measurement can be performed with simple equipment, but the positioning of the measuring microphone is not exact due to safety constraints
Solution Approach 1:
The measuring robot autonomously operates in the high-voltage environment, eliminating human exposure to electrical hazards. The robot independently navigates to precise measurement locations and performs measurements without safety constraints that would limit manual access, achieving both high positioning accuracy and complete operator safety.
Solution Approach 2:
The robot serves as an intermediary that can safely operate in high-voltage zones where human presence is restricted. It enables access to measurement points that would be inaccessible or unsafe for technicians, maintaining positioning accuracy while eliminating exposure to harmful high-voltage factors.
