Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual sighting method is used for laser emission, then the device complexity is low, but the measurement precision and productivity are poor
Solution Approach 1:
The patent replaces manual mechanical sighting with an automated system comprising an image acquisition system, image processing system, and control system. The image acquisition system captures target positions, the image processing system calculates coordinates, and the control system automatically adjusts laser emission angles, eliminating manual intervention and significantly improving precision.
Solution Approach 2:
The patent uses an image acquisition system to create a visual copy of the target scene, processing this optical information to determine precise laser aiming points. This allows the system to 'see' and calculate target positions accurately without manual observation, enhancing measurement precision while maintaining manageable system complexity through software-based processing.
2Productivity
If manual sighting method is used for laser emission, then the device complexity is low, but the productivity is poor
Solution Approach 1:
The system performs self-service by automatically acquiring target images, processing coordinates, calculating laser emission parameters, and adjusting emission angles without human intervention. This automated closed-loop control enables continuous operation and significantly improves productivity for foreign body removal on power transmission lines.
Solution Approach 2:
The patent implements continuous image acquisition and processing, allowing the system to track and remove multiple foreign bodies in sequence without manual repositioning or setup. The automated nature enables uninterrupted operation, maintaining high productivity while the integrated control system manages complexity through unified software control.
3Reliability
If conventional laser sighting is used, then the ease of operation is high, but the reliability is poor in dynamic environments
Solution Approach 1:
The patent incorporates feedback through the image acquisition system that continuously monitors target positions and the laser emission system that adjusts angles based on processed image data. This closed-loop feedback ensures accurate targeting even when foreign bodies move or are affected by wind, significantly improving reliability in dynamic environments.
Solution Approach 2:
The system dynamically adjusts laser emission angles in real-time based on processed image coordinates of moving targets. The control system modifies emission parameters continuously to track foreign bodies affected by wind or motion, maintaining high targeting accuracy and reliability despite changing environmental conditions.
