Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual height measurements are performed at predetermined intervals, then measurement accuracy can be achieved, but workability and productivity deteriorate due to separate processes for measurement and correction
Solution Approach 1:
The patent combines the height measurement function and the unevenness visualization function into a single surveying system. The distance measurement sensor and projection device work together to simultaneously measure and visualize surface unevenness, eliminating the need for separate measurement and correction processes. This merging of functions directly addresses the productivity issue by allowing workers to perform both tasks concurrently.
Solution Approach 2:
The patent creates a visual copy of the surface unevenness by projecting the measured height data onto the construction surface itself. The projection device displays the unevenness pattern directly on the work area, providing an intuitive visual representation that guides correction work. This copying approach maintains measurement precision while dramatically improving workability and productivity.
2Loss of information
If individual height measurements are performed manually, then detailed unevenness data can be obtained, but the complexity of the measurement process increases
Solution Approach 1:
The patent replaces manual mechanical measurement operations with an automated optical-electronic system. The distance measurement sensor automatically captures height data across the construction surface, and the projection device automatically visualizes the results. This substitution eliminates the need for manual measurement operations while preserving detailed unevenness information, thereby reducing process complexity.
3Reliability
If separate processes are used for concrete placing, height measuring, and correcting work, then each process can be optimized independently, but overall productivity deteriorates
Solution Approach 1:
The patent merges the measurement and correction guidance functions into a single integrated system. The surveying system provides real-time visualization of unevenness that guides the correction process, allowing workers to perform placement and correction concurrently. This merging maintains process reliability while significantly improving overall productivity by eliminating sequential process delays.
