Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current building automation systems (BAS) face challenges in integrating data with building information models (BIM), resulting in low-quality graphics and inefficient management of building equipment, as they require manual creation of graphics and lack seamless integration of dynamic data points with 3D building models.
Innovation Solution
A system that includes a BAS-BIM integrator to receive and integrate BAS points with a BIM, using a viewer to generate a user interface with graphical representations of building equipment and spaces, allowing users to interact and control systems within the BIM environment, including real-time data monitoring and control actions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If manual graphics creation is used in BAS, then system implementation is straightforward, but graphics quality is low and time-consuming
Solution Approach 1:
The patent uses BIM (Building Information Modeling) to create high-quality 3D graphical representations of building equipment and spaces. Instead of manually creating low-quality 2D graphics, the system copies and integrates the detailed BIM model data into the BAS interface, providing accurate and visually rich representations automatically.
Solution Approach 2:
The BIM model is created in advance during the building design and construction phase, containing detailed information about all building systems and equipment. This preliminary creation of the graphical model eliminates the need for time-consuming manual graphics creation during BAS implementation and operation.
2Ease of operation
If BAS and BIM are integrated, then data visualization and control are enhanced, but integration complexity increases
Solution Approach 1:
The patent merges the BAS data layer with the BIM graphical layer into a unified interface. The system integrates real-time BAS data (equipment status, sensor readings, control commands) with the corresponding BIM objects, allowing users to monitor and control building systems directly through the intuitive 3D BIM visualization rather than separate data displays.
Solution Approach 2:
The integrated BAS-BIM interface serves multiple functions simultaneously: it provides visual navigation of building spaces, displays real-time equipment status, enables data monitoring, and allows control operations. This multi-functional interface replaces multiple separate systems and simplifies user interaction despite the underlying integration complexity.
3Productivity
If BAS data is displayed through traditional interfaces, then implementation is simple, but user interaction with building equipment is inefficient
Solution Approach 1:
The patent transitions from traditional 2D flat interfaces to a 3D spatial representation using BIM. This dimensional enhancement allows users to interact with building equipment in its actual spatial context, providing intuitive navigation and understanding of equipment locations, relationships, and operational status, thereby improving management efficiency.
