Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual sampling inspection is performed by practitioners, then inspection can be conducted with simple tools, but the inspection results have subjective difference and lack quantitative data
Solution Approach 1:
The patent replaces manual mechanical inspection tools (angle square, levelling meter, taping rod) with an automated robotic system equipped with electronic sensors, cameras, and data processing capabilities. This substitution eliminates subjective human judgment and provides objective, quantifiable inspection results through electronic measurement and digital data collection.
Solution Approach 2:
The robotic inspection system performs self-positioning, self-measurement, and self-data-collection functions autonomously. The system uses its own onboard sensors and processors to conduct inspections without requiring human operators to manually position tools or interpret measurements, thereby eliminating subjective differences between inspectors.
2Reliability
If comprehensive inspection is performed manually, then all construction quality aspects can be inspected, but huge manpower cost is required
Solution Approach 1:
The robotic inspection system is designed as a multi-functional platform that can perform various inspection tasks (flatness measurement, crack detection, dimensional verification) using a single integrated system. This eliminates the need for multiple specialized inspectors and tools, achieving comprehensive inspection coverage while reducing manpower requirements.
Solution Approach 2:
The robotic system can continuously move through the construction space and perform inspections without interruption, unlike manual inspection which requires repeated positioning and setup. The automated system maintains continuous operation, significantly improving inspection efficiency while ensuring comprehensive coverage of all areas.
3Ease of manufacture
If simple tools are used for on-site inspection, then the inspection process can be performed with crude means, but it is impossible to reproduce the inspection process and results
Solution Approach 1:
The robotic system creates digital copies of the construction space and measurement data through electronic sensors and cameras. These digital replicas can be stored, analyzed, and reproduced indefinitely without loss of information, unlike manual measurements which are recorded on paper and subject to transcription errors and loss.
Solution Approach 2:
The system transforms physical construction parameters (dimensions, flatness, cracks) into digital data parameters that can be precisely measured, stored, and reproduced. This parameter transformation from physical to digital domain ensures complete information retention and reproducibility of inspection results.
