Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing BIM systems are not suitable for early design stages, requiring extensive information beyond conceptual sketches and lacking the ability to easily transition between sketch, CAD/3D design, and BIM models, making them time-consuming and inflexible.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional BIM systems are used at early design stages, then detailed design information can be obtained, but the system requires extensive information beyond conceptual sketches and lacks flexibility
Solution Approach 1:
The system dynamically adapts the level of design detail and model complexity based on the current design stage. At early conceptual stages, the system works with simplified representations and gradually increases detail as more information becomes available, allowing seamless transition between design phases without rigid constraints
Solution Approach 2:
The BIM system is designed to handle multiple design stages and input types universally. It can process conceptual sketches, bubble diagrams, and detailed designs within a single platform, serving both early-stage conceptualization and later-stage detailed modeling needs without requiring separate specialized tools
2Adaptability or versatility
If designers transition between sketch, CAD/3D design, and BIM model representations, then comprehensive design development is achieved, but the process becomes time-consuming
Solution Approach 1:
The system merges sketching, CAD/3D design, and BIM modeling into a single integrated workflow. Designers can begin with conceptual sketches and progressively develop the same model through different representation stages without manually redrawing or recreating elements, as the system automatically maintains and updates the design across all representation levels
Solution Approach 2:
The system performs preliminary automated actions to generate intermediate design representations. When a designer creates a conceptual sketch, the system automatically generates preliminary CAD/3D models and BIM structures, saving the manual time that would otherwise be required to create each representation from scratch
3Measurement precision
If BIM models are developed early in the design process, then detailed information is available, but the system lacks the ambiguity and flexibility needed for conceptual design
Solution Approach 1:
The system dynamically adjusts the level of model detail and information completeness based on the design stage. Early in the process, it maintains ambiguity and flexibility suitable for conceptual exploration, then progressively increases precision and detail as the design matures, allowing the same system to serve both conceptual and detailed design needs effectively
Data Source
AI summary
A method, apparatus, system, and computer program product provide the ability to dynamically generate a digital building information model. Design data for various designs is received. The design data for each design is encoded into a graph. A knowledge base is maintained and defines a model of design intent while processing and storing the graph. First user input of a goal or constraint is received. The knowledge base generates solutions based on the input. Second user input based on the solutions is received and used to iteratively train the knowledge base. The solutions are then output.
