Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The construction industry faces challenges in efficiently identifying and resolving object clashes in construction projects, particularly due to limitations in software technology for generating usable two-dimensional views from three-dimensional models for clash detection.
Innovation Solution
The development of new software technology that traces the intersection of a cross-section plane with objects in a three-dimensional model, determines respective two-dimensional boundaries, and generates a two-dimensional cross-sectional view for automated clash detection, allowing users to input object classes for clash identification and providing indications of clashes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual inspection methods are used for clash detection, then construction professionals can identify object clashes, but the process becomes time-consuming and error-prone
Solution Approach 1:
The patent replaces manual visual inspection with an automated computer-based system that performs clash detection by comparing geometric boundaries of objects in 2D cross-sectional views, eliminating human error and time consumption while maintaining detection accuracy
Solution Approach 2:
The system enables automated self-detection of clashes by algorithms that automatically compare object boundaries and identify intersections without requiring manual review, allowing the system to perform clash detection independently
2Loss of information
If three-dimensional models are used for clash detection, then comprehensive project information is available, but navigating and identifying clashes becomes difficult
Solution Approach 1:
The patent transforms 3D model data into 2D cross-sectional views that display object boundaries in a simplified format, making it easier to visually identify clashes while preserving the geometric information needed for accurate detection
Solution Approach 2:
The system extracts specific cross-sectional slices from the 3D model that contain potential clashes, separating relevant information from the complete 3D dataset to improve navigability and clash identification
3Ease of operation
If two-dimensional drawings are used for clash detection, then the format is universally recognized and compact, but automated clash detection capability is limited
Solution Approach 1:
The patent maintains compatibility with universal 2D drawing formats while enhancing them with automated clash detection algorithms, allowing the system to process standard 2D drawings and perform automated clash identification without requiring proprietary formats
Solution Approach 2:
The system uses 2D cross-sectional views as an intermediary representation that bridges the gap between 3D model data and automated clash detection, enabling algorithmic analysis while preserving the benefits of 2D format universality

AI summary
Techniques for facilitating automated two-dimensional (2D) clash detection on objects displayed within a 2D view generated from a three-dimensional (3D) model of a construction project involve (1) tracing an intersection of (i) a cross-sectional plane and (ii) two or more objects in the 3D model, (2) based on tracing the intersection, determining respective 2D boundaries of the two or more objects, (3) generating a cross-sectional 2D view that depicts the intersection and includes representations of the respective 2D boundaries of the objects in the 2D view, (4) causing an end-user device to present one or more user interface views for receiving user input indicating a clash detection scope, (5) based on data defining the clash detection scope, identifying any clashes between objects displayed in the generated 2D view, and (6) causing a respective indication of each identified clash to be displayed at the end-user device.
