Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If human workers perform photography for BIM integration, then traceability and convenience of construction management are improved, but man-hour consumption increases and worker safety deteriorates
Solution Approach 1:
The patent replaces the mechanical system of manual photography with an automated mobile robot equipped with a scanner. The robot autonomously moves through the construction site, captures images of construction members, and transmits them to the server, eliminating the need for human workers to perform manual photography while maintaining complete traceability of construction elements.
Solution Approach 2:
The mobile robot performs self-service by autonomously navigating the construction site, identifying construction members through its scanner, capturing images, and automatically transmitting data to the server. This self-service capability eliminates dependency on human operators, reducing man-hour consumption while preserving full traceability of construction elements.
2Loss of information
If human workers perform photography for BIM integration, then traceability and convenience of construction management are improved, but worker safety deteriorates
Solution Approach 1:
The patent replaces human workers with an automated mobile robot system that performs photography and data collection. The robot navigates construction sites autonomously, capturing images of construction members without exposing human workers to hazardous environments, thereby maintaining complete traceability while significantly improving worker safety.
Solution Approach 2:
The mobile robot serves as an intermediary between the construction site and the BIM system. It autonomously collects data about construction members and transmits this information to the server, eliminating the need for human workers to directly interact with potentially hazardous construction environments while ensuring complete traceability.
3Productivity
If automated mobile robot is used for scanning, then worker safety and efficiency are improved, but device complexity increases
Solution Approach 1:
The mobile robot is designed as a multi-functional device that combines autonomous navigation, laser scanning, image capture, and wireless communication capabilities in a single platform. This universal design allows one device to perform multiple tasks (scanning construction members, capturing images, transmitting data), improving efficiency while managing system complexity through functional integration.
Solution Approach 2:
The patent replaces multiple separate systems (manual photography equipment, data management systems) with an integrated mobile robot platform that performs scanning, image capture, and data transmission autonomously. This substitution improves productivity by consolidating functions into a single automated system, though it does increase device complexity.
