Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Displaying building status information, such as room occupancy, temperatures, and energy consumption, requires significant configuration work and lacks efficient visualization in existing systems, leading to cumbersome alphanumeric or graphic reports.
Innovation Solution
A method utilizing a digital building information model to automatically link data points with corresponding devices through a fuzzy search algorithm, enabling graphical representation of status information in 3D or 2D views on output devices, with data points linked via coordinated terminology and attributes, and updated in real-time for monitoring and operational control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If building status information is displayed using traditional alphanumeric or graphic reports, then the information can be presented, but the configuration work required is significant and the visualization is cumbersome
Solution Approach 1:
The patent applies preliminary action by pre-configuring the building information model (BIM) with all necessary building data, device information, and parameter relationships before the actual status display is needed. The BIM contains pre-defined associations between building elements and their corresponding control devices, so when status information needs to be displayed, the system can directly query and visualize the data without requiring complex configuration work at display time. This resolves the contradiction by moving the configuration effort to the modeling phase rather than the display phase.
Solution Approach 2:
The patent introduces a building information model (BIM) as an intermediary between the building's technical systems and the display interface. The BIM serves as a centralized database that stores structured information about building elements, devices, and their relationships. This intermediary layer simplifies the system by providing a unified access point to all building data, eliminating the need for complex direct connections between multiple control systems and display interfaces, thereby reducing both configuration effort and system complexity.
2Reliability
If detailed building status information is displayed, then monitoring capability is improved, but the configuration and data integration effort increases significantly
Solution Approach 1:
The patent applies preliminary action by pre-configuring the building information model (BIM) with all necessary building data, device information, and parameter relationships before the actual status display is needed. The BIM contains pre-defined associations between building elements and their corresponding control devices, so when status information needs to be displayed, the system can directly query and visualize the data without requiring complex configuration work at display time. This resolves the contradiction by moving the configuration effort to the modeling phase rather than the display phase.
Solution Approach 2:
The patent applies universality by designing the building information model (BIM) as a multi-functional platform that can display various types of building status information (temperature, humidity, occupancy, energy consumption, etc.) through a single unified interface. The BIM structure is designed to accommodate diverse data types and display formats, allowing the system to provide comprehensive monitoring capabilities without requiring separate configuration processes for different types of data, thereby reducing configuration time while maintaining reliable monitoring.
3Manufacturing precision
If building data is manually configured and linked to devices, then data accuracy can be ensured, but the configuration process becomes time-consuming and labor-intensive
Solution Approach 1:
The patent applies self-service by enabling the building information model (BIM) to automatically link building elements with control devices through automated data matching and association processes. The system uses automated algorithms to match BIM elements with corresponding devices based on identifiers, locations, and other key attributes, eliminating the need for manual configuration while maintaining data accuracy. This self-service approach allows the system to configure itself, significantly improving productivity without sacrificing the precision that would otherwise require manual verification.
Solution Approach 2:
The patent applies mechanics substitution by replacing the manual mechanical process of configuring and linking building data with automated computational processes. Instead of manually matching and linking BIM elements to devices, the system uses automated algorithms, database queries, and data matching techniques to establish relationships between building elements and control devices. This substitution of manual mechanical configuration with automated computational processes dramatically improves configuration efficiency while maintaining or even enhancing data accuracy through systematic validation rules.
