Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple distance meters are employed to measure multiple points simultaneously, then measurement speed is improved, but device complexity and manufacturing cost increase
Solution Approach 1:
The patent merges multiple measurement functions into a single distance meter by combining it with an optical axis deflection section. This single integrated system can measure multiple points on the target surface by deflecting the optical axis in different directions, eliminating the need for multiple separate distance meters while maintaining simultaneous measurement capability
Solution Approach 2:
The patent employs a dynamic optical axis deflection mechanism that can change the measurement direction in real-time. The optical axis deflection section allows the single distance meter to dynamically scan across multiple points on the target surface, achieving multi-point simultaneous measurement through rapid directional changes rather than using multiple static sensors
2Measurement precision
If collimation and measurement of target points is performed for at least three points, then inclination measurement is achieved, but processing time increases
Solution Approach 1:
The patent performs preliminary action by pre-calculating and storing the relationship between optical axis deflection angles and corresponding measurement point coordinates. During actual measurement, the system directly retrieves pre-computed inclination data based on measured coordinates, avoiding time-consuming real-time calculations and enabling rapid inclination determination while maintaining precision
3Measurement precision
If points to be used are selected on a PC after acquiring coordinate data, then inclination computation is performed, but post-processing time is required
Solution Approach 1:
The patent implements self-service by integrating the inclination computation function directly into the measurement device's control unit. The device automatically processes acquired coordinate data and computes inclination results without requiring external PC intervention or post-processing, enabling real-time inclination measurement while maintaining computational accuracy through built-in algorithms
