Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual measurement methods are used to estimate building wall area, then measurement accuracy can be maintained, but cost and time consumption increase significantly
Solution Approach 1:
The patent uses aerial images as copies of the building to create a digital model for wall area estimation. Instead of physically measuring the building, the system creates a scaled representation from aerial photography, allowing automated calculation of wall areas while maintaining accuracy. This copying approach eliminates the need for time-consuming manual measurements.
Solution Approach 2:
The patent replaces the mechanical measurement process (physical tools and manual measurement) with an automated image processing and calculation system. The system uses computer algorithms to analyze aerial images, generate 3D models, and calculate wall areas automatically, substituting mechanical measurement with computational analysis.
2Measurement precision
If manual measurement methods are used to estimate building wall area, then measurement accuracy can be maintained, but cost increases
Solution Approach 1:
The system creates a digital copy of the building from aerial images, enabling automated wall area calculation without requiring expensive manual measurement services. This copying approach maintains measurement accuracy while significantly reducing the cost associated with professional measurers and their time.
Solution Approach 2:
The patent implements a self-service measurement system where the building itself (through its aerial image) provides the data needed for wall area estimation. The system automatically extracts measurements from the aerial image without requiring external measurement services, making the process cost-effective and self-sufficient.
3Quantity of substance
If original building plans are used for wall area estimation, then measurement can be obtained, but reliability decreases due to outdated information
Solution Approach 1:
The system performs preliminary measurement and documentation capture through aerial imaging before any construction or renovation occurs. By capturing the building's current state through aerial photography and creating a digital model, the system ensures that measurements reflect the actual current conditions rather than outdated plan information.
Solution Approach 2:
Instead of relying on paper plans that may be outdated, the system creates current digital copies of the building through aerial imaging. This digital copying process captures the building's present state, ensuring reliability and accuracy of measurement data without depending on potentially obsolete plan documents.
4Productivity
If automated estimation systems are implemented, then productivity increases, but device complexity increases
Solution Approach 1:
The patent creates a multi-functional system that performs multiple tasks: capturing aerial images, generating 3D building models, calculating wall areas, and producing detailed reports. This universal system handles the entire wall area estimation process through a single integrated platform, improving productivity while managing complexity through consolidation rather than multiplication of separate tools.
