Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual position measurement and marking is used, then the system is simple to operate, but the measurement precision and work accuracy deteriorate
Solution Approach 1:
The driving-type working device performs self-position detection and self-correction by integrating the position detecting unit, sensing unit, and correcting unit. The device automatically compares its actual position with the movement path and corrects deviations without external intervention, enabling autonomous operation with high precision while maintaining operational simplicity
Solution Approach 2:
The driving-type working device integrates multiple functions including movement, sensing, position detection, path tracking, and self-correction into a single multi-functional system. This allows the device to perform both transportation and precision positioning tasks simultaneously, improving measurement accuracy without requiring separate complex systems
2Productivity
If repeated manual measurements are performed, then the system can handle complex environments, but the productivity and efficiency deteriorate
Solution Approach 1:
The system implements continuous feedback through the sensing unit that monitors the driving-type working device's position and environment in real-time. The position detecting unit compares actual position with the planned movement path, and the correcting unit automatically adjusts for deviations, ensuring high reliability and efficiency without repeated manual measurements
Solution Approach 2:
The patent replaces manual mechanical measurement methods with an automated electronic system comprising sensors, position detectors, and computer-controlled correction mechanisms. This substitution eliminates manual intervention while maintaining high reliability through automated feedback loops and electronic positioning control
3Manufacturing precision
If the driving-type working device operates without position correction, then the device complexity is low, but the manufacturing precision and work accuracy deteriorate
Solution Approach 1:
The patent merges the position detecting unit, sensing unit, and correcting unit into an integrated correction system that works as a unified subsystem within the driving-type working device. This combination achieves high work accuracy through coordinated operation of multiple components while minimizing overall device complexity through functional integration

AI summary
This application relates to a location measuring system including a driving-type working device. In one aspect, the system includes a data receiving unit that receives marking data about a working surface, a marking unit that executes a marking operation with respect to the working surface corresponding to the marking data, and a scanning unit that scans a target space. The system may also include a scan condition setting unit that sets a movement path of the driving-type working device corresponding to the marking data, sets a scanning position for scanning the target space in consideration of space map data corresponding to the target space, and sets a scan angle of the scanning unit at the scanning position. The system may further include a position detecting unit that compares scan data acquired via the scanning unit with the space map data to detect a position of the driving-type working device.
