Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a user manually checks the completion of installation and proper timing of laser light emission, then the device can be stabilized, but this work takes time and effort and varies depending on user skill
Solution Approach 1:
The device performs self-leveling and self-diagnosis using built-in sensors (acceleration sensors, tilt sensors) and control units. The system automatically detects installation conditions, determines whether leveling is complete, and identifies proper timing for laser emission without requiring manual user assessment, thereby eliminating time consumption and skill dependency while ensuring reliable stabilization
Solution Approach 2:
The system continuously monitors installation conditions through sensors and provides real-time feedback to the control unit. The control unit processes sensor data to determine installation completion and laser emission timing, creating a closed-loop system that automatically adjusts and confirms proper setup without manual intervention
2Reliability
If a user manually checks the completion of installation and proper timing of surveying, then the device can be stabilized, but this work takes time and effort and varies depending on user skill
Solution Approach 1:
The surveying device automatically monitors its own installation stability and surveying conditions using integrated sensors. The system self-determines when installation is complete and when surveying conditions are optimal, eliminating the need for users to manually assess stability and reducing operational complexity to simple button presses or automatic initiation
Solution Approach 2:
Manual mechanical assessment of installation stability and surveying timing is replaced by electronic sensor systems (acceleration sensors, tilt sensors) and automated control algorithms. The physical act of manual checking is substituted with electronic detection and automated decision-making, simplifying user interaction while improving reliability
3Measurement precision
If the device operates without automatic stabilization, then the structure remains simple, but accuracy is affected by environmental vibrations
Solution Approach 1:
Acceleration sensors and tilt sensors continuously monitor environmental vibrations and device orientation, providing real-time feedback to the control unit. The control unit processes this feedback data to determine when vibrations are within acceptable ranges and when the device is properly leveled, enabling accurate surveying operations while automatically compensating for environmental factors
Solution Approach 2:
The system monitors changes in vibration parameters and orientation parameters through sensors. By detecting parameter changes that indicate stable conditions (low vibration levels, proper leveling), the system automatically determines optimal surveying timing, maintaining high accuracy without requiring complex mechanical stabilization structures
