Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional blueprint-based positioning methods are used, then construction workers can position components using existing documentation, but the process requires substantial time for preparing and referencing blueprints, requires experienced personnel, and is prone to measurement errors
Solution Approach 1:
The patent replaces manual mechanical measurement methods with automated optical scanning technology. Electromagnetic radiation sources (lasers) and sensors automatically capture spatial data of the construction site, eliminating the need for manual blueprint reading and hand measurements. This substitution dramatically improves positioning accuracy while reducing the time required for measurement activities.
Solution Approach 2:
The patent creates a digital 3D copy of the construction site by scanning the environment with electromagnetic radiation. This digital model serves as a dynamic reference that automatically updates as construction progresses, replacing static blueprints. The digital copy enables precise measurement extraction without requiring workers to interpret complex 2D blueprint drawings.
2Adaptability or versatility
If manual measurements and blueprint reading are performed on-site, then customization to site conditions is possible, but the process is time-consuming and error-prone under difficult building site conditions
Solution Approach 1:
The patent replaces unreliable manual measurement processes with automated optical scanning systems. The electromagnetic radiation sources and sensors objectively capture spatial data without being influenced by worker experience levels or difficult site conditions. This automation maintains the ability to customize parts to site conditions while dramatically improving measurement reliability.
Solution Approach 2:
The scanning system automatically performs measurements and generates spatial data without requiring human intervention for each measurement. The system self-calibrates and continuously captures site conditions, enabling reliable customization data collection even under challenging construction environment conditions where manual methods fail.
3Manufacturing precision
If custom parts are fabricated based on manual measurements, then parts can be customized to fit site requirements, but the overall process from measurement to fabrication takes excessive time
Solution Approach 1:
The patent performs preliminary automated scanning and measurement capture at the construction site, immediately generating precise spatial data. This preliminary action provides accurate customization specifications to the factory without delay, enabling parallel processing of fabrication while site work continues. The result is both high manufacturing precision and improved overall productivity.
Solution Approach 2:
The patent replaces sequential manual measurement and documentation processes with automated optical scanning that instantly captures and transmits spatial data. This substitution eliminates time-consuming intermediate steps while maintaining the ability to produce highly accurate custom parts, thereby improving both manufacturing precision and construction productivity.

AI summary
A system and method for automatically manufacturing custom parts for use in a prefabricated construction site includes scanning a room under construction. The method also includes determining, based on the scan of the room, an image of an installation location in the room. The method also includes calculating, based on the image of the installation location, alteration dimensions for a prefab part. The alteration dimensions comprise alterations to the prefab part to match spatial dimensions of the installation location in the room. The method additionally includes transmitting, via a network, the alteration dimensions to a factory. The factory fabricates a custom prefab part according to the alteration dimensions.
