Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual measurement methods are used to estimate wall area, then measurement accuracy can be maintained, but cost and time consumption increase significantly
Solution Approach 1:
The patent creates a digital three-dimensional model that copies the physical building structure, allowing wall area measurements to be obtained from the digital model rather than through manual field measurements. This digital copy enables automated calculation of wall areas while maintaining accuracy through geometric computations.
Solution Approach 2:
The patent replaces manual mechanical measurement processes with an automated computational system. Instead of physically measuring walls with tools, the system uses image processing algorithms and three-dimensional modeling software to automatically calculate wall areas from aerial images and roof measurements.
2Measurement precision
If manual measurement methods are used to estimate wall area, then measurement accuracy can be maintained, but cost increases significantly
Solution Approach 1:
By creating a digital replica of the building, the system eliminates the need for expensive manual measurement services while maintaining measurement accuracy. The digital model can be generated from freely available or low-cost aerial images and roof measurements.
Solution Approach 2:
The system enables automated self-measurement of wall areas without requiring professional measurers. The computational algorithms automatically calculate wall areas from the digital model, making the measurement process independent and cost-effective.
3Quantity of substance
If original building plans are used for wall area estimation, then cost can be reduced, but reliability decreases due to unavailable or outdated plans
Solution Approach 1:
The system performs preliminary creation of a digital three-dimensional model that serves as a reliable, up-to-date representation of the building. This digital model is created before any measurement needs arise, ensuring current and accurate data is available when needed, replacing outdated or missing original plans.
Solution Approach 2:
The digital model creates an accurate copy of the current building state, ensuring reliability regardless of whether original plans exist. This digital replica captures the actual as-built conditions, providing more reliable data than potentially outdated original plans.
4Productivity
If automated estimation systems are implemented, then productivity increases, but device complexity increases
Solution Approach 1:
The system is designed to perform multiple functions using a unified approach: it processes aerial images, generates three-dimensional models, calculates roof areas, and determines wall areas all through the same digital modeling framework. This multi-functionality increases productivity while managing complexity through a single integrated system rather than separate specialized tools.
Data Source
AI summary
A wall area estimation system generates an estimated wall area measurement of a building based on the received roof measurements (e.g., those generated by, received from or found in a three-dimensional model of the roof) and a reference distance. The reference distance is a measurement indicative of a distance between the roof and a model ground surface placed on an image of the building where the walls of the building meet the ground. This reference distance may be used to determine how for down to extend the walls of the building (e.g., to a ground level) when building a three-dimensional digital model of the building to aid in generating wall area measurements. The resulting wall measurements, roof measurements, measurements of areas missing from the wall used to generate a wall estimate report, or a combined roof and wall estimate report including various different identifiers indicating the different features and measurements based on the three-dimensional model.
