Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional laser level systems with multiple components are used, then measurement capability is provided, but device complexity and operational difficulty increase
Solution Approach 1:
The patent combines the laser level, tripod, and elevation rod into a single integrated system. The laser level is mounted directly on the tripod, and the elevation rod with sensor board is coupled to the tripod, eliminating the need for separate components and reducing overall system complexity while maintaining measurement precision.
Solution Approach 2:
The tripod serves multiple functions: it supports the laser level, provides a mounting structure for the elevation rod, and acts as a stable platform for the entire measurement system. This multi-functionality reduces the number of separate components needed.
2Measurement precision
If traditional elevation measurement systems are used, then elevation data can be obtained, but loss of time occurs due to multiple setup steps
Solution Approach 1:
The laser level is pre-aligned and calibrated before use, and the elevation rod is pre-equipped with the sensor board and processing unit. This preliminary preparation eliminates the need for complex setup procedures during actual measurement, reducing setup time while maintaining data accuracy.
Solution Approach 2:
The system automatically performs elevation measurements without requiring manual calculation or complex operational steps. The sensor board detects laser reflections and the processing unit automatically calculates elevation data, reducing the time required for measurement operations.
3Measurement precision
If skilled operators with years of experience are required, then measurement accuracy can be maintained, but ease of operation decreases
Solution Approach 1:
The processing unit automatically processes sensor data and calculates elevation measurements without requiring skilled manual calculation. The system self-calibrates and performs measurements autonomously, making the operation simple while maintaining accuracy.
Solution Approach 2:
The sensor board provides continuous feedback on laser reflections, and the processing unit automatically adjusts calculations based on this feedback. This closed-loop system eliminates the need for skilled manual adjustment while maintaining measurement accuracy.
4Measurement precision
If multiple components are used for elevation measurement, then measurement capability is achieved, but productivity decreases due to increased setup and movement time
Solution Approach 1:
By integrating the laser level, tripod, and elevation rod into a single system, the patent eliminates the time required to move and setup multiple separate components. The unified structure allows for rapid deployment and efficient measurement operations, improving productivity while maintaining measurement capability.
